为在高产旱粮作物区改变粮食结构,增加经济收入,1976年以来,以井灌区大封公社为基点,对麦茬水稻旱种进行了连续7年的试验、示范工作.初步总结出了麦茬水稻早种的栽培经验.1982年共示范450亩麦茬水稻旱种,平均单产达664斤.其中50亩郑州早粳亩产696.7斤,45亩黎优57,亩产823.1斤.1.5亩地膜覆盖亩产889斤.稻麦两熟,年亩产1500斤以上.从而在旱粮区走出了一条发展水稻生产 In order to change the grain structure and increase the economic income in the high-yielding dry-land crop area, since 1976, based on the well-sealed commune in the well irrigation area, seven years of experiment and demonstration work have been carried out on dry cultivation of rice stubble, Early planting experience in 1982. A total of 450 acres of dry cultivation of rice crop in 1982, the average yield of 664 kg, of which 50 acres of Zhengzhou early Japonica per mu 696.7 kg, 45 acres of Lai 57, mu yield 823.1 kg mu Yield 889 catties.Rice and wheat two crops, the annual output of more than 1,500 pounds.Therefore, out of a dry grain area in the development of rice production
