高粱单位面积产量是由穗粒重和穗数决定的。穗数是人为控制的栽培因素,当密度一定时,产量的高低取决于穗粒重的大小。穗粒重是由穗粒数和千粒重两个因素决定的。研究表明,千粒重遗传力高,稳定性强,目前已达到一定的水平,现阶段高粱提高产量的主攻方向仍
Sorghum yield per unit area is determined by the grain weight per panicle and panicle number. Spike number is artificially controlled cultivation factors, when the density is constant, the level of output depends on the size of grain weight. The grain weight per spike is determined by two factors, the number of grains per spike and the weight of 1000 grains. Studies have shown that 1000-grain heritability high, strong stability, has reached a certain level, the main direction of sorghum to increase production at this stage is still
