目前生产上所推广的杂交水稻,在抽穗扬花期间如受高温或低温危害易形成大量空秕。因此,在一些人心目中的印象是杂交水稻产量高而不稳。然而我们公社马口大队种植的700多亩杂交晚稻,虽然近两年抽穗扬花期遇到了高温和低温,但仍然都获得了高产。1978年亩产946斤,1979年更上一层楼,破了千斤关。马口大队杂交晚稻增产的原因在哪里?主要是他们抓住了一个关键性措施——增加穗数。 At present, the hybrid rice promoted in production is easy to form a large number of empty pomfret during the period of heading and flowering if it is endangered by high temperature or low temperature. So, in some people’s minds, the impression is that hybrid rice is high and unstable. However, the 700-hectare hybrid late rice planted by our commune Shekou was still high in both high and low temperatures during the flowering and flowering stages in the past two years. 946 kg per mu in 1978, a higher level in 1979, breaking a thousand pounds off. Where are the reasons for the increased production of late rice in the hybrid rice plant of Shekou? The main reason is that they have taken a key measure - increasing the number of spikes.
