【摘要】 研究全生物降解农用地膜、聚乙烯和稻草覆盖3种不同处理对土壤含水量、土壤温度以及大顶苦瓜产量和经济效益的影响。试验结果表明,全生物降解农用地膜具有保温保水功能,而且能够达到预期降解效果,纯收入比较:全生物降解农用地膜>聚乙烯地膜>稻草覆盖,综合来看,K9-10全生物降解农用地膜在实践中使用效果较好。更多还原

【Abstract】 The effects of 3 different treatments of biodegradable agricultural mulch film, polyethylene film and straw mulching on soil water content, soil temperature, yield and economic benefit of Dading bitter gourd were studied. The results showed that the full biodegradable agricultural mulch film had the function of heat preservation and water retention and achieved the expected degradation effect. The order of net income is full biodegradable agricultural mulch film >polyethylene film>straw mulching.更多还原
