为了逐步推广棉田喷灌,今年我们在小港公社北港大队搞了120亩棉田喷灌试验示范,试验点共配备PV——50生流动喷灌机6台,配备195型柴汕机作动力,喷灌机实际射程30米,生产率为0.5亩/小时,于7月21日进行了一次喷灌,(因以后下了雨未进行二次喷灌),增产效果显著。据调查,喷灌示范区,亩产111.6斤,比对照流灌区亩产91.3斤增产18.19%。
In order to gradually promote sprinkler irrigation in cotton fields, this year we carried out 120 mu of cotton sprinkler irrigation experiments at the North Harbor Brigade of Xiao Gang Commune. The pilot stations were equipped with 6 PV-50 flow irrigation machines equipped with 195 Chaishan power and the actual range of irrigation machines 30 m and a productivity of 0.5 mu per hour. A sprinkler irrigation was carried out on July 21, and the effect of increasing yield was remarkable (no secondary sprinkler irrigation was carried out because of raining afterwards). According to the survey, sprinkler irrigation demonstration area, 111.6 kg per mu, 91.3 kg more mu than the control irrigation area yield 18.19%.
