大米是我国人民的主要食粮,以往只在水资源十分丰富的地区种值。但它能不能在水资源不十分充裕或地面灌溉有困难的地方种植并获得高产、稳产?近两年来,河南省临汝县寄料公社观上和雷湾两个大队进行了大面积的试验,证明利用喷灌灌水技术和其它农业技术措施配合完全可以种植并获得高产。1981年,这两个大队自筹资金七万元,在国家适当扶持下,仅半年时间建成了千亩喷灌系统,其中固定式喷灌系统100亩,半 Rice is the main food for our people, and in the past, it was only valued in areas with very rich water resources. But can it be planted in areas where water resources are not sufficient or where there is difficulty in surface irrigation and high yield and stable yield? In the past two years, a large area trial has been conducted by both the observation posts of Linru County Commune in Henan Province and the two brigades of Leiwan , Proved that the use of sprinkler irrigation technology and other agricultural techniques can be fully planted with high yield. In 1981, the two brigades raised their own funds of 70,000 yuan. With the proper support from the state, only a half mu of sprinkler irrigation system was built in half a year, of which 100 mu
