秸秆与生物炭配施对樱桃番茄生长及产量品质的影响

Effect of Straw and Biochar Application on the Growth and Yield Quality of Cherry Tomato

秸秆和生物炭配施可以提高作物的产量和品质。为筛选最适合樱桃番茄生产的秸秆与生物炭配施模式,本实验采用盆栽试验,研究了七种不同秸秆(椰糠,水稻秸秆,香蕉叶片,橡胶叶,木薯秸秆,菠萝秸秆,甘蔗残渣)与生物炭配施对樱桃番茄生长发育、产量及品质的影响。结果表明:和只施生物炭相比,木薯秸秆配施生物炭显著增加樱桃番茄18.5%的株高和12.0%的干物质量,香蕉秸秆配施生物炭显著增加樱桃番茄35.6%的SPAD值;木薯和香蕉秸秆与生物炭配施对樱桃番茄产量增加明显,较只施生物炭分别提高24.9%和21.9%,具体表现为每串果数和单果重的增加;秸秆与生物炭配施对樱桃番茄品质提升明显,木薯秸秆配施生物炭显著增加樱桃番茄75.0%的可溶性蛋白含量,椰糠配施生物炭显著增加樱桃番茄78.1%的维生素C的含量。因此我们建议生产中将木薯秸秆与生物炭配施以提高热带地区樱桃番茄产量和品质。本研究结果可以为热带地区樱桃番茄高效栽培提供依据,同时也为秸秆资源有效利用提供了参考。

Application of straw in combination with biochar can increase crop yield and quality.To screen the most suitable straw-biochar application pattern for cherry tomato production,this experiment used a pot experiment to study the effects of seven different straws(coconut bran,rice straw,banana leaf,rubber leaf,cassava straw,pineapple straw,and sugarcane bagasse)applied in combination with biochar on the growth and development,yield and quality of cherry tomato.The results showed that compared with biochar application only,application of cassava straw in combination with biochar increased plant height and dry matter mass of cherry tomatoes by 18.5%and 12.0%,application of banana straw in combination with biochar significantly increased the SPAD of cherry tomatoes by 35.6%.Application in combination with cassava and banana straw significantly increased the yield of cherry tomatoes by 24.9%and 21.9%,respectively,compared to biochar application only,and the increase in yield was due to the increase in the number of fruits per bunch and weight per fruit.The quality of cherry tomatoes was significantly improved by the application of straw and biochar in combination,cassava straw with biochar application significantly increased the soluble protein content of cherry tomatoes by 75.0%,and coconut bran with biochar application increased the vitamin C content of cherry tomatoes by 78.1%.Therefore,we recommend the application of cassava straw with biochar to improve the yield and quality of cherry tomatoes in tropical areas.The results of this study can provide a basis for the efficient cultivation of cherry tomatoes in the tropics and also provide a reference for the effective utilization of straw resources.
