我区杂种优势在粮食生产上的应用是从包谷开始的,随后又从水稻试验示范。杂种优势的利用是农业科学技术上的一项重大成果。我区杂交优势的利用,是从无到有,从少到多,从点到面逐步扩大的,其种植效果在不同的社队表现有一定的差异。究竟是否增产?增产幅度多大?杂交优势表现如何?是否有发展前途?应从实研究?从实得出较为正确的结论,便于认真开展农业科学实验活动,进一步提高科学种田水平,促进农业大上快上。为此,我们对我区近年来杂交优势的利用情况进行了调查研究,现把材料整理分析如下。
The application of heterosis in grain production started from Baogu and then from rice experiment. The utilization of heterosis is a major achievement in agricultural science and technology. The advantages of hybridization utilization in our region are from scratch, from less to more, and gradually expanded from point to area, and the planting effect has some differences in performance of different communes and teams. Whether or not to increase yield? How much yield increase? How good is the hybrid advantage? Is there a promising future? From the actual research? Derived from the more correct conclusions, to facilitate serious agricultural science experiment activities to further improve the level of scientific farming, . To this end, we conducted a survey on the utilization of hybrid advantages in our district in recent years. Now we analyze the materials as follows.
