水稻是一种具有分蘖特性的作物,在一穴稻中,有主穗,也有分蘖穗。一般情况是带蘖的稻株个体发育较好,穗大粒多。根据我们多年的试验,在生产中,采取稀播壮秧,中蔸密植,合理水肥,积极促进早生分蘖成穗,对增加每亩穗数和粒数,提高产量,比单纯依靠本苗,增加每亩穗数和粒数较为有利。下面是我们的试验、观察情况。一、主茎和分蘖的结实情况近年来,我们在水稻生产、科研中 Rice is a crop with tillering characteristics. In one-hole rice, there are main spikes and tillering spikes. In general, tillering rice plants developed well, large spikelets and more. According to our many years of experiments, in production, we should adopt thinning and sowing seedlings, medium and dense planting and reasonable water and fertilizer, and actively promote early tillering to spike. To increase the number of spike and grain per acre and increase the yield, Spike per acre and the number of grains is more favorable. Here is our test, observe the situation. First, the main stem and tillering firm In recent years, we are in rice production, research
