水稻产量构成因素中,每亩穗数和每穗颖花数在生产上很容易达到预定的指标,而千粒重受环境影响较小,只有结实率是最难办的事。在我省水稻生产中,一般结实率为70—80％,有的仅有30—40％,严重地影响产量。有关科技工作者和农民对此非常关心,都在寻求最行之有效的措施来解决这个难题。笔者想通过本文同大家一起讨论。水稻结实是在各种环境因子的影响下,通过水稻体内复杂的生理生化过程实现的。因此,要提高水稻结实率必然应从品种和环境控制着手。
Among the components of rice yield, the number of spikes per acre and the number of spikelets per panicle can easily reach the predetermined target in production. However, the 1000-grain weight is less affected by the environment. Only the seed setting rate is the most difficult task. In rice production in our province, the general seed setting rate is 70-80%, while some only 30-40%, seriously affecting the yield. Concerned sci-tech workers and farmers are all looking for the most effective measures to solve this problem. I want to discuss with everyone through this article. Rice is strong in a variety of environmental factors under the influence of the body through the complex physiological and biochemical processes in rice to achieve. Therefore, it is inevitable to improve the seed setting rate of rice varieties and environmental control.
