为确保麦苗全、齐、匀、壮、必需做到:①土地平整细碎,墒情良好.上松下实。②播种量准确,排口流量一致,种子和肥料分布均匀。③播深一致.不过深过浅,复土严密。保证达到上述要求的措施是提高整地、机械、播种和种子质量.其中整地是基础。对春季干旱的东北春麦区春小麦生产来说,整地的主要作用,除协调耕层土壤中土粒、水分和空气三者之间的关系,为小麦顺利萌发、出苗和正常生长,创造良好的土壤环境之外,还在于有效地接纳和保存前一年的伏、秋降水,做到伏、秋雨春用。水分是小麦萌发、出苗的首要条件,也是东北春小麦生产的重要限制因素。播种时种子能否播在湿土上和耕层中有无足够的水分供出苗和生长需 In order to ensure wheat seedlings all, Qi, uniform, strong, must be done: ① land formation fine, moisture is good. ② accurate sowing, outlet flow consistent, evenly distributed seeds and fertilizers. ③ sowing the same depth, but too shallow, complex soil tight. The measures to ensure that the above requirements are met are to improve soil preparation, machinery, sowing and seed quality, of which land preparation is the foundation. For the spring wheat spring wheat spring area northeast spring wheat production, the main role of soil preparation, in addition to coordination of topsoil soil, water and air, the relationship between the three for the smooth germination of wheat, emergence and normal growth, and create a good soil Outside the environment, but also lies in the effective acceptance and preservation of the previous year’s volt, autumn precipitation, so volts, autumn rain with. Moisture is the primary condition of wheat germination, emergence, but also an important limiting factor for the production of spring wheat in Northeast China. Seeds can be sowed on sown wet soil and plow for sufficient water for seedling and growth needs
