    The tomato is one of fruits and vegetables the most extensively cultivated worldwide.While it is botanically a fruit, it is considered a vegetable for culinary purposes. It contains 13 vitamins and 17 mineral substances,abundant with Vc,and lycopene content proves the highest. Hence, the tomato is one of fruits as well vegetables enjoying higher nutritional value. Currently, the tomato is widely cultivated in China.For example,Lingshui County,Hainan Province, has become national production base of cherry tomato, with growing cultivation area. What’s more, the goal of fruit and vegetable production has changed from yield into quality improvement[1].Additionally,the content of nutrients of soils has effects on tomato growth[2]. Recently, researches have been conducted on the effects of soil nutrients on quality of horticultural plants, with progress. For instance,Li et al.[3]explored the relationship between soil nutrients and fruit quality in Xinken apple gardens,Mayan District. Cheng et al.[4], Fallahi et al.[5], Hilmelroch et al.[6]and Palmer et al.[7]made exploration on correlation between soil nutrients and apple quality. Bao et al.[8]investigated the status of soil nutrients in Newhall navel orange garden in Hubei Province and the effects on fruit quality, proposing that TSS content showed linear correlation with the contents of available P and available K.Ma et al.[9]researched that the increase of P fertilizer would improve the content of soluble sugar in tomato and the increase of K fertilizer would improve the contents of soluble sugar, Vc and amino acid within certain extent. Ning et al.[10]explored the effects of highly-concentrated K on yield and quality of tomato and pointed out that K fertilizer at 9 mmol/L would increase the content of TSS and K fertilizer at 12 mmol/L would significantly decrease nitrate, and the sugar-acid ratios of K fertilizer increased by 9.67% and 10.70% compared with control group.Zhu et al.[11]investigated that K fertilizer applied in tomato field would improve Vc content and sweetness of tomato. Pan et al.[12]re-searched that proper P fertilizer would advance tomato yield and improve the quality, but both of yield and quality would be decreasing by excessive P fertilizer. Wang et al.[13]explored the effects of steel and iron slag zinc fertilizers on tomato yield and quality,which indicated that the fertilization of N,P and K fertilizers, added with steel and iron slag zinc fertilizers would increase the content of soluble sugar by 4.74% -7.11% . Zhang et al.[14]researched the effects of Mg, B, Zn and Mo on quality and yield of tomato and proposed that Mo fertilizer would increase soluble sugar of tomato, which was contrary to Mg,B and Zn.Yang et al.[15]explored that soluble fertilizers,“Songtian” golden Ca would improve quality of tomato. Zhao et al.[16]investigated the effects of fertilizations on tomato yield and quality and proposed that the fertilization of inorganic fertilizers would maintain high contents of soluble sugar and titratable acid. Cui and Wang researched the effects of fertilization structure on tomato nutrient quality and pointed out that the contents of Vc, and soluble sugar,sugar-acid ratio, and content of nitrate would be increased in the treatment with organic fertilizer, ammonium sulfate, superphosphate and potassium sulphate[17]. Han et al.[18]made investigation the effects of compound fertilizers added with manganese ion on tomato quality and concluded that Mn-AA would improve the contents of Vc,soluble solids,soluble protein and free amino acid,reduce titratable acid content and increase sugar-acid ratio.Researches available are more on fruit trees, but less attention is paid to effects of soil physical and chemical properties on tomato quality. On the other hand, because of regional differences, the standard values concluded from researches tend to be volatile,which will be difficult in leading cultivation of cherry tomato. Hence, it is of great significance for advancing balance fertilization technology, improving fruit yield and quality, and promoting sustainable development of fruit industry to grasp the correlation between cherry tomato quality and soil physical and chemical properties. In order to further explore the correlation between soil nutrients and cherry tomato quality in Lingshui County,Hainan Province, based on field survey and room experiment in 8 cherry tomato producing areas, the correlation between TSS content of cherry tomato and soil properties was explored, which provides references for construction of cherry tomato garden and guidance of cultivations.

    Materials and Methods

    The test soils were sampled from cherry tomato producing area in Lingshui County, and the test materials were Qianxi grafted cherry tomato,provided by Known You Seed (China)Co. Ltd. Specifically, the plants were grown with planting space at 85cm×60cm, in November 2012, as per local method and the room experiment was in February 2013. During harvest period,the sampling depth maintained 12 cm in different regions to measure physical and chemical properties of soils. Furthermore, TSS content of fruits was measured when the 5th ear matured, and three farmland fields were chosen from every region, with 10 repetitions of every field.

    The test data were processed with Microsoft Excel 2003 and analysis of variance and test of significance were conducted as per Duncan method with SPSS 10.0.

    Table 1 Physical and chemical properties of test soils

    Results and Analysis

    Soil physical and chemical properties

    As shown in Table 1, pH value of test soils was in the range of 5.10-5.85, of which the value in Changpoyang, Xincun Town, reached the highest,and in Poliuyang, Yelin Town,Laodangyang, Timeng Village, and Liangyayang, Wenluo Town were reached the lowest at 5.10. The content of organic matter maintained in 0.800-2.245 g/kg, including maximum of Anmayang, Yelin Town and minimum of Huashiyang, Sancai Town.Alkali-hydrolyzale nitrogen content kept in the range of 36.750-99.600 mg/kg, including maximum of Anmayang, Yelin Town and minimum of Laodangyang, Timeng Village. Thecontent of organic P was in 21.867-96.125 mg/kg, involving the highest of Poliuyang, Yelin Town and the lowest of Liangyayang, Wenluo Town. The content of available K maintained in 14.750 -92.857 mg/kg, including the minimum of Liangyayang, Wenluo Town, and the maximum of Anmayang, Yelin Town. In terms of exchangeable Ca,the content was in the range of 157.100-589.050 mg/kg,and the content achieved the highest in Daqianyang, Guangpo Town, and the lowest in Huashiyang, Sancai Town.Exchangeable Mg content kept in 4.400-38.943 mg/kg, and the content was the highest in Anmayang, Yelin Town and the lowest in Changpoyang,Xincun Town. The content of Fe was from 87.800 to 1 388.025 mg/kg, and was the highest of Liangyayang,Wenluo Town and the lowest in Huashiyang, Sancai Town. The content of Mn was in 8.950-62.100 mg/kg,and reached the peak of Huashiyang,Sancai Town and the lowest of Changpoyang, Xincun Town. The content of Cu was in 2.530-1.665 mg/kg, reaching the highest of Changpoyang, Xincun Town, and the lowest in Anmayang, Yelin Town. The content of Zn changed in the range of 5.095-13.131 mg/kg,achieving the highest in Anmayang,Yelin Town and the lowest in Laodangyang, Timeng Village. The content of S maintained in the range of 4.825 -34.100 mg/kg, reaching the highest of Changpoyang,Xincun Town and the lowest of Zhongyangyang,Benhao Town.

    TSS content of cherry tomato

    The contents of TSS in Daqiangyang, Guangpo Town and Anmayang, Yelin Town were 10.467%and 10.317%, respectively in Lingshui County, Hainan Province, with insignificant differences, followed by Huashiyang,Sancai Town and Zhongyangyang, Benhao Town at 9.507%and 7.422% , with little differences,showing significant differences with that in other regions. The content of Poliuyang, Yelin Town, was 8.967%,ranking the 3rd, showing insignificant differences with Laodangyang,Timeng Village and Liangyayang, Wenluo Town and significant differences with that in other regions. The contents of TSS in Laodangyang, Timeng Village and Liangyayang, Wenluo Town were 8.883% and 8.567%, respectively, showing insignificant differences with that of Poliuyang,Yelin Town and significant differences with that of other regions.The content of Changpoyang,Xincun Town was the least at 7.800%,with significant differences with that of other regions.

    Table 2 TSS contents of cherry tomato

    Table 3 Correlation of TSS content of cherry tomato with soil physical and chemical properties

    Relationship of TSS content of cherry tomato with soil physical and chemical properties

    As shown in Table 3,TSS content was of extremely significant positive correlation with the content of exchangeable Ca,with correlation coefficients at 0.587**and 0.514**,of significantly positive correlation with the content of Zn, with correlation coefficient at 0.324*, of extremely significant negative correlation with the content of Cu, with correlation coefficient at -0.613**, and of significantly negative correlation with the content of S, with correlation coefficient at-0.332*.

    Conclusions

    In the research, available K made the largest contribution of the accumulation of TSS content, which coincides with researches made by most scholars on other horticultural plants,namely, available K would advance the accumulation of TSS in fruits. Furthermore, the effects of exchangeable Ca proves higher on TSS content of cherry tomato, which is in consistent with that of Yang ’s[11], and Zn would promote the increase of TSS in cherry tomato also, which is similar to that made by Zhang et al.[10]. The research explored that S played a more powerful role in inhibiting TSS accumulation of cherry tomato, and organic P had inhibition effects on TSS accumulation,which are different with that made by Bao et al.[8]or by Ma et al.[9], possibly caused by sensitivity degrees of researched species. What’s more, in some regions in the research, S content was higher, which was in consistent with that of Pan’s[12], possibly caused by inhibition on other elements,and the most suitable content of P in soils requires further exploration. In terms of trace elements, the research incorporated that Mg, Zn and Mn would increase the content of TSS,which is different with that made by Zhang et al.[14],but similar to that made by Han et al.[18]. Qi et al.[19]proposed that common effect of invertase and sucrose synthetase is a major factor influencing sugar accumulation in tomato, and more exploration requires on the range of nutrient elements, and the relationship of the content of available K,exchangeable Ca,and Zn,with invertase and sucrose synthetase. It can be concluded that within a certain extent,it is key for improving quality of cherry tomato in Lingshui County,Hainan province to increase the contents of available K, exchangeable Ca and Zn.
