我们呼盟无霜期短,大部地区春季干旱严重,适时早播,缩短播期,是抢墒下种,巧用积温,战胜低温冷害,一次播种保全苗的重要措施。根据全盟各地经验,种大田作物改变过去“立夏到小满,种啥也不晚”的习惯,做到“谷雨到立夏,突击把种下”,就可以抢出积温100℃左右,延长了作物的生长期。我盟灌溉条件很差,大面积生产主要靠保住土壤中的自然墒情,因此,搞好整地保墒

We call the union frost-free period is short, most of the spring drought serious, timely sowing, shorten the sowing date, is to grab moisture under the kind of, clever use of temperature, to overcome cold damage, an important measure of seedling preservation. According to the experience of the League, field crops have changed the habit of “setting up summer to small fullness and farming is not too late.” After the achievement of “grain rain to the beginning of summer and assault planted”, it is possible to grab out the accumulated temperature of about 100 ℃ and extend the crop The growth period. I League irrigation conditions are poor, large-scale production of soil by retaining the natural moisture, therefore, do a good job of soil moisture
