近几年来,我国农业产业结构不断调整,经济作物种植面积逐年增加,其中烤烟种植下田的面积越来越多,种烟的产值远远高于种粮产值,但粮食产量大面积下降,烟农粮食不能自给,出现了无粮不稳心,为了解决这些现象,我们基层农业推广部门经多年试验示范,目前寻找出中低海拔地区烟后种植水稻的栽培技术。其关键技术就是选好生育期短、耐寒、抗病、早熟的优良品种,合理
In recent years, the structure of China’s agricultural industry has been continuously adjusted, and the area under cultivation of cash crops has increased year by year. The area under which potatoes are planted in flue-cured tobacco is increasing. The output value of tobacco is much higher than the output value of grain-growing crops. However, In order to solve these problems, our grassroots agricultural extension department, after many years of experiments and demonstrations, is currently looking for ways to cultivate rice grown at low and medium altitude in the future. Its key technology is to select good varieties with short growth period, cold tolerance, disease resistance and early maturity, and reasonable
