Abstract:

Objective To investigate the effects of intermittent irrigation in paddy fields on mosquito control and the impact on growth and yield of rice. Methods The paddy fields were divided into an experimental group and a control group. In the same context of other measures,the experimental group was performed with intermittent irrigation and the control group with convention? al irrigation. The densities of larvae of Anopheles sinensis and Culex tritaeniorhynchus were surveyed by the suction trapping meth? od. The plant traits,leaf age process,tiller dynamics,yield structure and actual rice production were observed. Results Com? pared with the control group,the average densities of larvae of Anopheles sinensis and Culex tritaeniorhynchus were reduced of 10.32/m2 and 13.93/m2 respectively in the experimental group,the control rates were 79.84% and 72.14% respectively,the aver? age yield increased of 22.5 kg/667 m2 ,water conservation was 187.4m3 /667m2 , and the increased revenue was 75.78 yuan/667 m2 . Conclusions The intermittent irrigation in paddy fields not only can control mosquito larva breeding effectively,but also save wa? ter and electricity,and increase the harvest.

摘要:

目的 目的 探讨稻田间歇灌溉法控制蚊蚴效果及其对水稻生长和产量的影响。方法 方法 在其他措施完全相同的前提下, 以土壤水势为指针, 对试验田、 对照田分别实行间歇和常规灌溉, 于水稻生长全程定人、 定期、 定点采用吸捕法调查按蚊和库蚊幼虫密度; 以植株性状、 叶龄进程、 茎蘖动态、 产量结构和实际产量等指标评判水稻长势和产量。结果 结果 试验田中华按蚊和三带喙库蚊幼虫平均密度分别比对照田减少10.32条/m2 和13.93条/m2 , 防制率分别达78.84%和72.14%; 试验田比对照田每667 m2 平均增产22.5 kg , 节水187.4 m3 , 增收节支75.78元。结论 结论 稻田间歇灌溉不仅可有效控制蚊蚴孳生,还能节水、 省电、 增收。
