1960年在昔阳大寨调查玉米增产经验时,注意到劳模陈永贵的玉米深播种能控制幼苗生长,促进后期生长发育,达到稳定高产的经验。我省其他地区的农民群众也有类似说法。总结研究这一经验,不仅具有实践价值,而且也有其理论意义。1961年和1963年,我们对这一经验进行了研究。通过研究企图明确:1.深播种是否会引起先控制后促进的变化。2.这种变化是否与丰产有联系。3.摸索上迎变化的生理实质。
In 1960, when surveying corn yield increase in Xiyang Dazhai, he noticed that the deep seeding of Chen Yougui, a model worker, could control seedling growth, promote late growth and development and achieve stable and high-yielding experience. The peasant masses in other parts of our province have similar views. To sum up this experience is not only of practical value but also of theoretical significance. In 1961 and 1963, we studied this experience. Through the research attempt to clarify: 1 whether deep seeding will lead to the change after the first control. 2. Whether this change is related to high yield. 3. Groove on the changes in the physical understanding of the essence.
