    Key words Chenopodium quinoa Willd., Large-scale development, Present situations, Suggestions

    1 Introduction

    Chenopodium

    quinoa

    Willd. is native to South America. It is a crop product resistant to drought, low temperature and barrenness.

    C

    .

    quinoa

    Willd. has rich nutritional value and is rich in a variety of nutrients, and can resist in adjuvant treatment for many diseases. Therefore,

    C

    .

    quinoa

    Willd. is more and more favored by people all over the world, many countries begin to introduce

    C

    .

    quinoa

    Willd. for planting, and the world market is very huge. China has a large population base and a large demand for

    C

    .

    quinoa

    Willd. With the Chinese people’s in-depth understanding of

    C

    .

    quinoa

    Willd., China will become the largest producer and consumer of

    C

    .

    quinoa

    Willd. in the future. Therefore, at present, it is necessary to promote the large-scale production and planting of

    C

    .

    quinoa

    Willd., so as to meet the needs of Chinese people for

    C

    .

    quinoa

    Willd.

    2 Present situation of large-scale development of C. quinoa Willd.

    2.1 Variety research needs to be strengthened

    In the current

    C

    .

    quinoa

    Willd. cultivation, many

    C

    .

    quinoa

    Willd. varieties are not studied enough. The varieties of

    C

    .

    quinoa

    Willd. are not optimized enough, and the plant and ear types of many

    C

    .

    quinoa

    Willd. varieties are separated and the height is not consistent. There is a large color gap. The maturity period of the same

    C

    .

    quinoa

    Willd. variety in the field is also different. Therefore, the above phenomena show that the current research on

    C

    .

    quinoa

    Willd. varieties is insufficient.

    2.2 Insufficient mastery of training environment and cultivation techniques

    In the current planting of

    C

    .

    quinoa

    Willd., there are many factors that will affect its growth. Altitude, for example, has a great influence on

    C

    .

    quinoa

    Willd. The seed setting rate of

    C

    .

    quinoa

    Willd. is low in areas with lower elevations. If the temperature is more than 30 degrees Celsius, it will also cause

    C

    .

    quinoa

    Willd. not to bear fruit. And

    C

    .

    quinoa

    Willd. is also greatly affected by the threat of various diseases and pests. How to control

    C

    .

    quinoa

    Willd. diseases and pests is also a difficult problem and key research field. However, the current actual situation is that the related research on the influence of altitude, yield and quality in

    C

    .

    quinoa

    Willd. planting is insufficient. There are even gaps in many areas.

    2.3 Large-scale planting is not enough

    For the large-scale planting of

    C

    .

    quinoa

    Willd., many domestic companies do not pay enough attention and lack participation, and do not realize the importance of large-scale planting of

    C

    .

    quinoa

    Willd. and its large-scale industrial benefits. The company’s awareness of large-scale production is not enough, so the enthusiasm and participation in

    C

    .

    quinoa

    Willd. large-scale production is not high.

    2.4 Degree of planting mechanization is not enough

    At present, due to the characteristics of

    C

    .

    quinoa

    Willd., the degree of mechanization of

    C

    .

    quinoa

    Willd. planting is not enough. In the planting of

    C

    .

    quinoa

    Willd., it is difficult to mechanize the precision sowing of

    C

    .

    quinoa

    Willd. because of the small quantity of seeds used, and the degree of mechanization of

    C

    .

    quinoa

    Willd. sowing is not high in the actual planting of

    C

    .

    quinoa

    Willd. In the harvest season of

    C

    .

    quinoa

    Willd., due to the variety problems of

    C

    .

    quinoa

    Willd., the height of

    C

    .

    quinoa

    Willd. is highly uneven and the maturity is not consistent, which makes the mechanization of

    C

    .

    quinoa

    Willd. harvesting difficult. Therefore, the degree of mechanization in the current

    C

    .

    quinoa

    Willd. harvest is not high.

    3 Suggestions on strengthening the large-scale development of C. quinoa Willd.

    3.1 Increasing investment in

    .

    Willd. variety research

    At present, one of the problems in the large-scale production of

    C

    .

    quinoa

    Willd. is that the quality of

    C

    .

    quinoa

    Willd. varieties is uneven, and there is still a lot of room for improvement in the overall quality of

    C

    .

    quinoa

    Willd. varieties. Only if the variety of

    C

    .

    quinoa

    Willd. is good, can we provide a good beginning for the large-scale production of

    C

    .

    quinoa

    Willd. and realize the possibility of large-scale planting of

    C

    .

    quinoa

    Willd. If the varieties of

    C

    .

    quinoa

    Willd. are not good, even if efforts are made to expand the large-scale production of

    C

    .

    quinoa

    Willd., the results will not be the best. Therefore, the variety research of

    C

    .

    quinoa

    Willd. is the top priority to increasing the large-scale production of

    C

    .

    quinoa

    Willd. products.To increase the investment in

    C

    .

    quinoa

    Willd. variety research, we can start from the following aspects: first, it is necessary to increase the investment in variety research and development of

    C

    .

    quinoa

    Willd., which can be carried out with the help of the relevant producers of

    C

    .

    quinoa

    Willd. The second is to increase the training of talents related to

    C

    .

    quinoa

    Willd. variety research, so as to provide the possibility for the research and development of new

    C

    .

    quinoa

    Willd. varieties. The talent for

    C

    .

    quinoa

    Willd. variety research can be cultivated within the enterprise or through the introduction and absorption of outstanding talents in the society. The third is to increase the importance to large-scale production of

    C

    .

    quinoa

    Willd.

    3.2 Strengthening analysis of the introduction and screening of

    .

    Willd. varieties

    C

    .

    quinoa

    Willd. is an exotic variety, and domestic research on

    C

    .

    quinoa

    Willd. varieties also needs a process and time. So how can we strengthen the large-scale production of

    C

    .

    quinoa

    Willd. during this period? We can start from the introduction and selection of

    C

    .

    quinoa

    Willd. varieties. Professional staff should be organized to study and analyze the existing varieties of

    C

    .

    quinoa

    Willd., and then the local climate, geography, soil and other conditions should be considered before selecting and introducing the

    C

    .

    quinoa

    Willd. varieties most suitable for local growth and cultivation.

    3.3 Studying the optimum planting environment and cultivation techniques of

    .

    Willd.

    At present, a problem in the cultivation of

    C

    .

    quinoa

    Willd. in China is that there is not enough mastery and research on the planting environment and cultivation techniques of

    C

    .

    quinoa

    Willd. in China. In order to carry out large-scale production of

    C

    .

    quinoa

    Willd., it is necessary to have deep understanding and mastery of the planting environment and early culture techniques, and to train various

    C

    .

    quinoa

    Willd. producers and skilled workers. At present, the existing research results are that fresh

    C

    .

    quinoa

    Willd. is suitable to grow in areas with high altitude, and the higher the altitude is, the colder the temperature is, which is more suitable for the planting of

    C

    .

    quinoa

    Willd. and the increase of its yield. However, at present, the research on how humidity affects the growth of

    C

    .

    quinoa

    Willd. is relatively vague, and agronomists have not yet obtained a more reliable conclusion and results. At present, there are some studies on whether

    C

    .

    quinoa

    Willd. is suitable to be planted in saline-alkali soil in China. The suitable growth environment of

    C

    .

    quinoa

    Willd. should be studied, and the research on the planting and cultivation techniques of

    C

    .

    quinoa

    Willd. is also a top priority.The cultivation techniques of

    C

    .

    quinoa

    Willd. can be studied from the following aspects: The first is to study the suitable sowing time of

    C

    .

    quinoa

    Willd. Choosing the appropriate sowing time of

    C

    .

    quinoa

    Willd. can reduce the effect of temperature at flowering stage on the growth of

    C

    .

    quinoa

    Willd. and make

    C

    .

    quinoa

    Willd. have a higher pollination rate. The second is to study the suitable planting mode of

    C

    .

    quinoa

    Willd., involving ridging and film mulching planting, intermission seeding, out-of-season planting, multiple cropping and so on. The third is to study the fertilizer and the proportion of fertilizer needed in the planting of

    C

    .

    quinoa

    Willd. It is best to develop a special fertilizer for growing

    C

    .

    quinoa

    Willd. We should have a clear conclusion on the proportion of fertilizer needed and determine what kind of fertilizer is needed for each growth period of

    C

    .

    quinoa

    Willd., in order to facilitate the large-scale planting of

    C

    .

    quinoa

    Willd. The fourth is the study on the diseases and pests to

    C

    .

    quinoa

    Willd. The main diseases and pests are cutworms and sparrows. For the control of cutworms, we can apply pesticide to the soil before planting

    C

    .

    quinoa

    Willd. to play a certain control effect. Anti-sparrow net is mainly used to control sparrows in

    C

    .

    quinoa

    Willd. planting. Fifth, there is no herbicide specifically for

    C

    .

    quinoa

    Willd. planting at present. And any herbicide is easy to cause drug damage to

    C

    .

    quinoa

    Willd. In view of this phenomenon, it is necessary to strengthen the research on professional herbicides for

    C

    .

    quinoa

    Willd. cultivation.

    3.4 Increasing the scale of mechanized production of

    .

    Willd.

    When introducing and planting

    C

    .

    quinoa

    Willd. varieties, we should consider how to mechanize the introduction of

    C

    .

    quinoa

    Willd. Mechanized production can reduce the input of human labor and production cost. In order to carry out large-scale mechanized production of

    C

    .

    quinoa

    Willd., it is necessary to optimize it from the following aspects: first, it is necessary to strengthen the research on

    C

    .

    quinoa

    Willd. varieties to make the maturity time difference of

    C

    .

    quinoa

    Willd. varieties as small as possible, which is conducive to the large-scale harvest of

    C

    .

    quinoa

    Willd. The second is to improve the machinery to adapt to the characteristics of small quantity of seeds used in the sowing period of

    C

    .

    quinoa

    Willd., making it possible to use mechanized production on a large scale when sowing

    C

    .

    quinoa

    Willd.

    3.5 Increasing the research and development of

    .

    Willd. related products and their deep processing technologies

    One of the forces that

    C

    .

    quinoa

    Willd. needs for large-scale production can be the research and development of

    C

    .

    quinoa

    Willd. related products and deep processing technologies. At present, the developed

    C

    .

    quinoa

    Willd. products include wine, drinks, baked goods, fine dried noodles, biscuits, bread, pastries, all kinds of snacks and health products, cosmetics, beauty products and so on. Other

    C

    .

    quinoa

    Willd. related products and deep processing technologies need to be studied with more attention in the future.

    4 Conclusion

    In this paper, based on the study of

    C

    .

    quinoa

    Willd. planting, it is concluded that the current situations of large-scale development of

    C

    .

    quinoa

    Willd. include the following four aspects: first, the research on

    C

    .

    quinoa

    Willd. varieties needs to be strengthened; second, it is insufficient to master the training environment and cultivation techniques; third, the large-scale planting of

    C

    .

    quinoa

    Willd. is not enough; fourth, the degree of mechanization of

    C

    .

    quinoa

    Willd. planting is not enough.In view of the above situation, this paper puts forward the following effective suggestions to strengthen the large-scale development of

    C

    .

    quinoa

    Willd.: the first is to increase the investment in

    C

    .

    quinoa

    Willd. variety research; the second is to strengthen the analysis of introduction and screening of

    C
