摘要
在石灰岩丘陵桑园行间进行了覆盖地膜、覆草、土壤施保水剂、松土等 4种土壤保水技术的试验 ,结果表明 :其保水效果、春季桑树生长和产叶量为覆膜 >保水剂 >覆草 >松土 >对照 ,秋季桑树生长和产叶量为覆草 >保水剂 >覆膜 >松土 >对照。
In this paper,four techniques of preserving soil moisture,which include covering field film,covering grass,applying super absorbent polymer and loosening soil in the mulberry field of limestone hill,were studied.The results showed that:the order for the effects of preserving moisture and that for growth and yield of mulberry leaves in spring were film covering>absorbsent polymer>grass covering>soil loosening>check,that for growth and yield of mulberry leaves in autumn was film covering>absorbsent polymer >grass covering>soil loosening>check.
