一、人民胜利渠灌区旱种水稻的必要性 河南引黄人民胜利渠灌区,一直是个旱作区。粮食作物的栽培主要采用小麦——玉米的轮作倒茬种植制度。历年旱作秋粮产区,粮食结构简单,都是粗粮。变粗粮为细粮,改善食物结构,这是广大人民的要求。70年代以后,灌区水稻种植面积逐年增加,到80年代初已发展到十三万亩,几乎占灌区总灌溉面积的近1/4,出现了小麦——水稻一年两熟的稻麦轮作栽培制度。实践证明后者比前者优越。对促进灌区粮食增产,增加农民收入,满足城乡人民对大米的需求,起了一定的作用。
First, the people victory Drainage Irrigation District, the need for dry rice Drainage Henan Yin Triumph people, has been a dry area. The cultivation of food crops mainly uses wheat-corn rotation cropping system. Dry pasture autumn grain production areas, grain structure is simple, are coarse grains. Coarse grains for fine grain, improve food structure, which is the majority of people’s requirements. Since the 1970s, the area under rice cultivation in the irrigated area has been increasing year by year. By the early 1980s, it has grown to 130,000 mu, accounting for almost one quarter of the total irrigated area in the irrigated area. There has been a rice-wheat crop with double ripening of wheat and rice system. Practice has proved that the latter is superior to the former. It has played a certain role in boosting grain output in irrigated areas, increasing farmers’ income and meeting the demand of rice by urban and rural residents.
