肥水一体化膜下滴灌在日光温室越冬茬黄瓜上的应用

Application of the Dripping Irrigation with Fertilizer in Cucumber Planting in Greenhouse in Winter

[目的]探寻在日光温室作物栽培中可有效利用水资源的灌溉技术。[方法]采用示范对比的方法研究了肥水一体化膜下滴灌技术在日光温室越冬茬黄瓜上的应用效果。[结果]试验得出,滴灌比漫灌可节省费用5985元/hm2,平均增产23755 kg/hm2,增产率为20.99%,每茬可节水4318 t/hm2,比漫灌节水近一半。[结论]肥水一体化膜下滴灌技术经济和社会效益显著,应大力推广。

[ Objective ] The irrigation technique with efficient use of water for crop cultivation in greenhouse was explored. [ Method ] The effect of the technique of dripping irrigation with fertilizer trader plastic film on cucumber growth in greenhouse in winter was compared. [ Results ] The cost of 5 985 yuan/hm^2 could be saved in the dripping irrigation more than the flooding irrigation;the average yield of 23 755 kg/hm^2 could be increased with an increase rate of 20.99% .4 318 ton water per hectare in each crop growing season could be saved with the technique and the amount of water-using with this technique was nearly half of the flooding irrigation. [ Conclusion] The technique of dripping irrigation with fertilizer under plastic film could produce good economic and social benefits significantly and should be vigorously promoted.
