Effect of Drip Irrigation and Furrow Irrigation Under Plastic Film on Growing Development and the Growing Environment of Cucumber

The effect of furrow irrigation,drip irrigation and general furrow irrigation under plastic film on yield,pests and diseases situation of cucumber and indoor environmental conditions were studied.The results showed that indoor humidity of furrow irrigation and drip irrigation under plastic film than general furrow irrigation lower were 3.8%~4.9% and 3.3%~6.1% respectively,day and night difference in temperature were 1.5~2.3℃,and 1.6~2.6℃ respectively,relatively high of soil temperature.By the methods of furrow irrigation and drip irrigation under plastic film on water management of cucumber,incidence and disease index of downy mildew and powdery mildew of lower than the normal furrow irrigation.the difference was significant or very significant level.
