小麦播种前科学整地是实现小麦一播全苗的基础,做到科学整地就是针对不同作物的茬口、土壤质地情况、当地生态气候条件、因地制宜的选择不同的整地方法,达到理想的播种状态。越冬期田间管理的中心任务是在保苗的基础上,促根增蘖,使弱苗转壮。壮苗稳长,确保麦苗安全越冬,为来年穗多、穗大打下良好的基础。1小麦播前整地要点小麦的根系比较发达,其中70%集中在距地表10~30厘米的耕层内,播前做好精
The scientific land preparation before sowing of wheat is the basis for realizing the whole wheat sowing. Scientific land preparation aims at the stubble of different crops, the soil texture, the local ecological and climatic conditions, and the selection of different land preparation methods according to the local conditions to achieve the ideal sowing status. Overwintering field management center mission is to seedlings in the foundation, to promote tillering, so weak seedling strong. Strong seedling stable, to ensure safe winter wheat seedlings, for the coming year spike, spike large lay a good foundation. Wheat before sowing the main points of wheat germ more developed, of which 70% concentrated in 10 to 30 cm above the surface of the tillage, sowing fine
