有机肥替代化肥对大棚黄瓜生产的影响

Effects of organic fertilizer instead of chemical fertilizer on cucumber production in greenhouse

本研究旨在通过对比分析不同比例有机肥配施对大棚黄瓜生产的影响,筛选出黄瓜种植中有机肥配施最佳比例,为设施黄瓜生产的科学施肥提供参考。本试验在大棚黄瓜上增施有机肥,减施不同数量的化肥,探究其对黄瓜产量、效益和品质的影响。结果表明,施用有机肥+减施不同比例的配方肥与习惯施肥比较,均能明显提高黄瓜产量,增产6483.45~11382.60 kg/hm^(2),增幅达10.7%~18.8%,黄瓜种植效益和施肥效应明显增加。生产中增施有机肥同时减施16%化肥,可以达到减少化肥施用量,提高经济效益的效果。此外,施用有机肥能明显降低黄瓜硝酸盐含量,增加其可溶性蛋白含量,降低其有机酸含量,从而改善产品品质。

This study aims to analyze the influence of different organic fertilizer application proportion on cucumber production in greenhouse,and select the best proportion of organic fertilizer application in cucumber planting,so as to provide reference for scientific fertilization in facility cucumber production.In this experiment,the effects of increasing organic fertilizer and decreasing different amounts of chemical fertilizer on the yield,efficiency and quality of greenhouse cucumbers were investigated.The results showed that the application of organic fertilizer+reduced application of different proportions of formula fertilizer could increase the yield of cucumber compared with that of conventional fertilizer,increasing the yield by 6483.45~11382.60 kg/hm^(2)(10.7%~18.8%),and the planting efficiency and fertilization effect of cucumber were significantly increased.In the production of increase the application of organic fertilizer and reduce the application of 16%fertilizer,can achieve the effect of reducing the application of chemical fertilizer and improving the economic benefit.In addition,the application of organic fertilizer could significantly reduce the nitrate content of cucumber,increase the content of soluble protein,reduce the content of organic acid,so as to improve the product quality.
