小麦的高产与良种、密度、施肥、防治病虫等很多因素有关,其中还有一个重要的条件,就是要把好播种质量关。播种质量不好,出苗率不高或出苗不整齐,弱苗太多或密度不够,是今后的技术措施难以弥补的。因而必须高度重视精细播种的问题,为小麦的高产打下基础。精细播种包括哪些要求呢? 1、精选种子通过半年多时间的保管,种子有可能被虫蛀或发生霉变,精选种子可以淘汰瘦小种子,清
The high yield of wheat is related to many factors such as seed quality, density, fertilization, pest control and so on. There is also an important condition that the quality of sowing should be well controlled. Sowing quality is not good, the emergence rate is not high or irregular emergence, weakness too much or the density is not enough, is the future of technical measures difficult to make up. Therefore, we must attach great importance to the issue of precision sowing, laying the foundation for the high yield of wheat. What are the requirements of precision sowing? 1, Selected seeds through more than six months of custody, the seeds may be moth-eaten or mildew, the selection of seeds can be eliminated thin seed, clear
