多功能秸秆腐熟剂对设施番茄产量和品质的影响

Effect of Multifunctional Straw Decomposition Inoculants on the Yield and Quality of Tomato in Greenhouse

以设施番茄为研究对象,在玉米秸秆还田的基础上,研究了多功能秸秆腐熟剂对设施番茄生长和品质的影响。结果表明：施用多功能秸秆腐熟剂的处理与不施用腐熟剂的CK1相比,提高了番茄产量,改善了番茄品质,其中单产增加9.29%,可溶性蛋白质、维生素C、可溶性糖含量分别比对照增加了12.70%、17.00%、7.01%。此外,施用多功能秸秆腐熟剂促进了土壤中秸秆的腐熟,不同程度增加了土壤速效养分含量,其中碱解氮增幅为64%-89%,速效磷增幅为60%-90%,速效钾增幅为37%-79%,同时降低了土壤EC值;综上所述,在该区域种植大棚番茄,应提倡玉米秸秆还田,不仅可降低1/3左右磷钾用量,并且配合施用多功能秸秆腐熟剂,可以达到番茄稳产、增产、优质的目的。

The study was conducted in tomato greenhouse to investigate the influence of multifunctional straw decomposition inoculants application on the yield and quality of tomato.The results showed that the application of multifunctional straw decomposition inoculants promoted the yield and quality of tomato,the yield increased by 9.29%,soluble protein,vitamin C and soluble sugar content increased 12.70%,17.00%,7.01%than that of CK1,respectively.Moreover,application of multifunctional straw decomposition inoculants promoted the decomposition of straw in soil and increased the soil nutrient-element levels that available nitrogen increased by 64%-89%,available phosphorus increased by 60%-90%,available potassium increased by 37%-79%.In addition,application of multifunctional straw decomposition inoculants also decreased the soil EC.In summary,the greenhouse tomato should be advocated to use the corn straw,which could not only reduce 1/3of total P and K application rates,but also achieve the purpose of increasing yield,stable production and high quality in this area.
