当前，小麦产量由高产向超高产迈进。１９９８～２０００年我们根据超高产小麦的技术环节提出各生育期的镇压对产量的关系进行示范研究。现将关键技术措施总结如下。１．播种后的镇压此期镇压能增加土壤紧实度，连接土壤毛细管促使土壤下层水分上升，利于保墒。同时，还可以促?
At present, the output of wheat is shifted from high yield to high yield. From 1998 to 2000, we put forward the demonstration research on the relationship between the yield and the repression of each growth period according to the technical aspects of the super-high-yield wheat. The key technical measures are summarized below. 1. Post-seeding repression This period of repression can increase soil compaction, connecting the soil capillaries to promote soil moisture in the lower soil, which will benefit soil moisture. At the same time, you can promote?
