关于高粱生长锥的发育,解放后有人做过研究,但到目前为止,对高粱在不同条件下,其生长锥发育进程的影响以及外界条件和产量之间的关系,尚无人进行研究。我们知道,提高单位面积产量主要是依靠两个方面,一方面是增加密度,增加单位面积总穗数,另一方面是增加穗大粒多、粒重,因此了解在不同因素条件 Some studies have been done on the development of sorghum growth cone after liberation. So far, no studies have been conducted on the relationship between the sorghum growth cone development process and the external conditions and yield under different conditions. We know that increasing yields per unit area mainly depends on two aspects. One is increasing the density, increasing the total number of spikes per unit area, and the other is increasing the number of spikelets and grain weights. Therefore, we know that under different factors and conditions
