俗话说:“麦收三件宝,头多、穗大、粒子饱。”小麦单位面积产量是由每亩穗数、每穗粒数和粒重三个因素构成的,三者相乘即为每亩产量。在这三个因素中,任何一个数量的增大,都有可能提高产量,但这三者是互相制约的。在一定的栽培条件下,在一定的范围内,这三者可以同时提高,从而提高产量,但超过了一定范围,则个体和群体矛盾激化,如穗密度过大时,穗子就
As the saying goes: “Wheat received three treasure, head and more, big spike, full of particles.” Yield per unit area of wheat is per acre spike, grain number per spike and grain weight of three factors, the three multiplied by each Mu production. In any of these three factors, the increase in any one of them may increase the output, but the three restrict each other. Under certain cultivation conditions, within a certain range, these three can be increased at the same time to increase the yield. However, when the range exceeds a certain range, the contradiction between individuals and groups is intensified. For example, when the spike density is too large,
