自六十年代以来,我省沿黄灌区水稻发展很快,一些水源条件好的地方也种植水稻,形成我省北方稻麦两熟区,这对发展我省的粮食生产,调剂人民生活有着重要意义。从我省北部地区的生态条件看,基本上能满足水稻对光、温的要求,七、八月份雨量充沛,温度高,这时正处水稻需水的高峰期,对水稻前期生长十分有利。生长后期雨量少,日照较长,昼夜温差大,病虫害较轻,有利于水稻籽粒形成与灌浆。高产田块的
Since the 1960s, the rice in the irrigation areas along the Yellow River has been developing rapidly. Some rice with good water conditions have also been planted in paddy fields to form the rice-wheat two-crop zone in the northern part of our province, which is of great importance to the development of grain production in our province and the adjustment of people’s livelihood significance. From the ecological conditions in the northern part of our province, it basically meets the requirements of rice for light and temperature. In July and August, abundant rainfall and high temperature are at the peak of water demand for rice, which is very beneficial to the growth of rice in the early stage. In the late growth period, less rainfall, longer sunshine, large temperature difference between day and night, pests and diseases lighter, is conducive to the formation of rice grains and grouting. High yield plots
