杂交水稻的空秕率问题,对产量影响很大。为了寻找减少空秕粒的途径,我们作了一些试验研究。下面兹将研究初步结果概述如下。一、杂交水稻空秕粒形成的原因当前生产中造成杂交水稻空秕率偏高的原因大体有四个方面:一是高、低温的 The problem of the empty rice rate of hybrid rice has a great impact on the yield. In order to find ways to reduce the empty particles, we made some experimental research. The following is a summary of the preliminary results of the study. First, the reasons for the formation of hybrid rice empty noodles In the current production of hybrid rice caused by the high empty rate is generally four aspects: First, high and low temperature
