小麦的高产稳户是靠协调个体与群体的关系来实现的。在‘定的光照、温度、水分、养分、品种条件下,只有确定相适应的群体结构,才能夺取小麦高产。而在一定密度条件下,要协调好个体与群体的关系,采用合理的播种方式是重要的一环。传统的犁播方式,由于受机具限制,很难达到这个目的。如犁杖开沟多呈船底形,播下的种子往往形成上、中、下 The high yield and stability of wheat depend on the coordination of individuals and groups. Under the set conditions of light, temperature, moisture, nutrients and breeds, only high-yielding wheat can be seized if the appropriate group structure is determined. Under certain density conditions, to coordinate the relationship between individuals and groups, it is an important part to adopt reasonable sowing methods. The traditional plowing method, due to the constraints of the machine, it is difficult to achieve this purpose. Such as the cane ditches were mostly ship-shaped, sowing seeds often form the upper, middle and lower
