| Abstract: | 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. |
