摘要
为给露地黄瓜生产及土壤培肥提供参考,以猪粪为变量因素,采用随机区组设计,对露地黄瓜产量和土壤养分的影响进行研究。结果表明:在露地黄瓜的生产中,1.50kg.m-2的猪粪施用量为最佳施用量,不宜过多,另通过施入猪粪还可以增加土壤中速效氮、速效磷、速效钾和有机质的含量,且随着施用量的增加而增加,增强土壤肥力。
Taking pig manure as variable factors, adopting random district design, the effect of pig manure on the yield and soil nutrients of Cucumis sativus Linn were studied to provide reference for production of Cucumber in open and fertilization in soil. The results showed that the production of Cucumis sativus Linn in open, the best amount of pig manure was 1 500 kg per 1 000 m2 ,and should not be too excessive,besides,applying pig manure could increase the content of available nitrogen,available phosphorus, available potassium and organic matter in soil, moreover, with the application rate increased, the soil fertility enhanced.
