杂交水稻制种稳产高产的首要前提是父母本花期理想相遇,而要达到花期相遇,除了确定适宜的播种差期外,花期预测和花期调节工作是必不可少的技术环节。目前普遍应用的幼穗剥查、叶龄余数、氮肥控制等方法存在明显的局限性。本文就这方面介绍我们研究的结果。 一、杂交稻制种花期
The first prerequisite for stable and high yield of hybrid rice seed production is the ideal meeting of the parents of the flowering, and to meet the flowering, in addition to determine the appropriate sowing difference, the flowering and florescence forecasting regulation is an essential technical aspects. Currently widely used method of spike inspection, leaf age residue, nitrogen fertilizer control and other methods have obvious limitations. This article describes the results of our study in this regard. First, hybrid rice flowering
