| Abstract: | Potato was used as an indicating crop to study the effects of plastic film mulching and fertilization on potato dry matter accumulation,soil water content and yield in dryland.The results shows that plastic film mulching could make potato dry matter accumulation of the whole plant,tuber and overground part significantly higher than no film mulching treatment,and optimum fertilization treatment(OPT)could make it higher than FP(tradition fertilization treatment) and CK(no fertilization) for whole growing period.The plastic film mulching treatment in soil water content of 21 to 80 cm soil depth was higher than the uncover film mulching.The plastic film mulching treatment in efficiency of water application(WUE) and yield was observably higher than no film mulching treatment,OPT was higher than FP and CK,and all the differences were significant between treatments. |
