我省处于冬麦种植区域的北部边缘,又是夏秋两季作物轮作的种植地带,“三夏”、“三秋”时间短任务大,夏秋两季播种,往往因劳力、肥料、茬口等安排不当,使部分农田形成晚种晚收,晚收晚种的恶性循环,产量不稳。适当扩大春麦面积,可以起到调节农时,合理安排茬口,精细整地,增施肥料,提高播种质量,保苗增产的效果。特别是改棉田钻种冬麦为春小麦与棉花套种,对防止冬小麦丛矮病(即毒病)为害,保证棉粮双丰收有积极作用。总
The province is at the northern fringe of the winter wheat planting area and is also the planting area for crop rotation in summer and autumn. The tasks of “Sanxia” and “Sanqiu” are short in time and are sown in summer and autumn, and are often arranged improperly due to labor, fertilizer and stubble , So that part of the farmland to form a late crop late harvest late late varieties of the vicious circle, yield instability. Appropriate to expand the area of spring wheat, can play a role in regulating agriculture, rational arrangements stubble, fine preparation of land, increase fertilizer, improve sowing quality, seedling yield increase effect. In particular, changing the cotton field drill winter wheat wheat and cotton interplanting, to prevent winter dwarf dwarf disease (ie, poisonous disease) damage, to ensure a double-bumper cotton harvest has a positive effect. total
