江汉平原是长江中游的大豆主产区。六十年代以后,由于稻棉生产的发展,大豆面积和总产锐减。近几年来,不少地方开始重视豆科作物,特别是随着农业生产责任制不断完善,广大农民已采取灵活多样的间、套、复种形式发展大豆生产,不断提高单位面积产量和培肥地力。 在江汉平原发展大豆生产,是扩大麦豆两熟制,还是发展豆稻、豆棉两熟或麦豆稻、麦豆棉三熟制?笔者认为后一种途径对发展大豆和稻棉生产均有利,也较符合江汉
Jianghan Plain is the main producing area of soybean in the middle reaches of the Yangtze River. Since the 1960s, due to the development of rice-cotton production, the soybean area and the total output plummeted. In recent years, many places have begun to attach importance to leguminous crops. In particular, as the responsibility system for agricultural production continues to improve, the vast majority of farmers have adopted flexible and diversified forms of soybean production to continuously raise the yield per unit area and the fertility of fertilizers . The development of soybean production in the Jianghan Plain is to expand the wheat double cropping system, or the development of leguminous rice, bean or cotton two crops, wheat, wheat, rice, cotton three cooked system? The author believes that the latter approach to the development of both soybean and rice cotton production Favorable, but also more in line with Jianghan
