一、提高小麦产量的主要途径小麦的产量决定于亩穗数、穗粒数和粒重三因素。穗数取决于群体,穗粒数和粒重取决于个体发育状况。一般来说,导致亩穗数多的群体变化是矛盾的主要方面,个体发育好坏,往往依赖于群体结构是否合理。因此,协调好群体与个体的关系,解决好多头与倒伏、穗多与穗大、粒多粒重的矛盾,使小麦穗数、穗粒数和粒重协 First, the main way to improve wheat yield Wheat yield is determined by the number of acres per spike, grain number and grain weight of three factors. The number of spikes depends on the population, and the number of grains per spike and grain weight depend on the individual’s development. In general, group changes that lead to a large number of ears per acre are the main contradictions. Individual development tends to depend on whether the group structure is reasonable. Therefore, to coordinate the relationship between groups and individuals, to solve the long and lopsided, spike and spike, grain and more weight conflicts, so that the number of spikelets of wheat, spikelets and grain weight Association
