摘　　要：试验初步探讨了浅水晒田(A)、浅水不晒田(B)、深水晒田(C)和深水不晒田(D)4种水分管理模式对水稻病虫害的发生及产量的影响。结果表明,深水晒田(C)耗工时耗电最多,管理成本最高;深水不晒田(D)病虫害发生严重,产量最低;浅水晒田(A)水分管理方式病虫害发生较轻,产量最高。Four kinds of water management models, shallow irrigation drying field （A）,shallow irrigation without drying field （B）, deep irrigation drying field （C） and deep irrigation without drying field （D） ,were used to study their effects on rice diseases and insect pests occurrence and yield. The results showed that model D had the highest consumption of working hours and power with the highest management cost. Model C had the most serious diseases and insect pests and the lowest yield. Model A had the slightest diseases and insect pests and the highest yield.
