杂交水稻高度稀播,培育多蘖壮秧,增产效果明显。常规二季晚稻培育多蘖壮秧效果如何呢?本试验证明,同样具有明显的增产效果。据本次试验观察,每亩秧田播种20斤的多蘖秧,比亩播200斤的无蘖秧增产14.6％,亩播40斤的比亩播200斤的增产12.8％。因此,常规二季晚稻品种,也可推广高度稀播以培育多蘖壮秧来夺取高产。 Hybrid rice is highly sowing, cultivating more tillering seedlings, yield significantly. Conventional seasons late rice cultivated tiller seedling effect how? This test proved that the same yield has obvious effects. According to this experiment, more tillering seedlings of 20 kg per mu were planted, yielding 14.6% more than 200 kg of non-tillering seedlings per mu, yielding 12.8% more yield than 200 kg of sowing 40 kg per mu. Therefore, the conventional two seasons late rice varieties can also promote highly thin sowing to cultivate more tiller seedlings to win high yield.
