水稻旱种是从水稻旱直播基础上发展起来的新技术,它是水稻灌溉上的一项革新。水稻由于育秧移栽和水层管理,需要大量用水,特别在我国北方稻区,水源不足成为限制水稻发展的主要因素。为了扩种水稻,近几年来,各地因地制宜地创造了各种类型的水稻旱种:其中有北京郊区和黑龙江的苗期旱长、后期水层管理的;有山东和河北的麦田套种、后期水层管理的。河南省则采用麦后直播、苗期旱长、后期不留水层灌跑马水的办法,1982年试种1.2万亩,高产的在800斤以上,一般的亩产500斤左右,受到了广大群众的欢迎。据1982年统计,北方稻区水稻旱种的

Rice dry cultivation is a new technology developed from the dry planting of rice, which is an innovation in the irrigation of rice. Due to the transplanting of rice seedlings and the management of water layer, rice needs a lot of water, especially in the paddy areas in the north of our country. The shortage of water resources has become the main factor limiting the rice development. In order to expand paddy rice, various types of dry farming of rice have been created in various places in recent years. Among them, there are the long dry years of seedling in Beijing’s suburbs and Heilongjiang Province, and the management of later water layers; the intercropping of wheat fields in Shandong and Hebei, Layer management. Henan Province is the direct broadcast after wheat, wheat seedling drought, the late irrigation method does not leave the water Ma, 1982 trial of 1.2 million mu, high yield of 800 pounds or more, the general yield of about 500 pounds per mu, by the vast Welcome by the masses. According to the 1982 statistics, the dry cultivation of rice in the northern rice area
