1.早腾茬,抢早播晚茬麦冬前早春苗小、苗弱的主要原因是播种迟积温不足,因此,早茬、抢时间是争取有效积温,夺取高产的一项十分重要的措施。在不影响秋季作物产量的情况下,尽力做到早腾茬,早整地,早播种,加快播种进度,减少积温的损失,争取小麦带蘖越冬。为使前茬作物早腾茬,对晚收作 Early stubble, grab early seeding Early stubble in early spring before Ophiopogon seedling is small, seedling weak mainly due to lack of late planting temperature, therefore, stubble, snatching time for effective accumulation of temperature, to seize the high yield of a very important measure . Without affecting the yield of autumn crops, we try our best to get early t incrmentation, early planting and sowing as soon as possible to speed up sowing progress, reduce the accumulated temperature loss and win winter with tillers of wheat. To make the crop before the early Teng crop, late harvest
