目前对于以稻麦等有分蘗习性作物为对象的“群休概念”的争论,大致上可归纳为两个问题,一个是稻麦大田群体中有无“自动调节”的机能,另一个是争取高产究竟应该“依靠主茎还是依靠分蘗。”前者是大田群体中茎数消长变化规律的机质问题,后者是主茎与分蘖之间的关系问题。两者同是由于个休与群休之间的矛盾而产生的,也是指导生产、决定合理密度的理论依据。“自动调 At present, the debate about the concept of ”group breaks“ targeting tillering crops such as rice and wheat can be roughly divided into two problems, one is the function of ”automatic adjustment “ in the field group of rice and wheat, The other is to fight for high-yield should ”The former is dependent on the main stem or tiller. “ The former is the population of the population growth and decline in the law of the body of the problem, which is the relationship between the main stem and tiller. Both are due to the conflict between a break and group break, which is also the theoretical basis for guiding production and determining the reasonable density. ”Auto-tune
