根据历年丰产经验总结与试验研究资料,论述了北方高产稳产水稻田的主要栽培技术,水稻生长发育和产量构成因素间的关系。同时,以北方高产水稻实例对“群体概念”、“主蘖关系”等进行了讨论。 Based on the summery and experimental research data of the past years, the paper discussed the main cultivation techniques of paddy field with high and stable yield in North China, and the relationship between the growth and development and the components of rice yield. In the meantime, the concept of “colony” and “main tiller relationship” were discussed with the examples of high-yielding rice from the north.
