入春以后,甘蓝型油菜进入孕蕾抽苔阶段。此时油菜自交不亲和系剥蕾授粉制种工作也即将进行。但如何做好剥蕾授粉,以提高制种效果?根据几年来的实践,我们认为应掌握以下几个主要技术环节:1、选择适宜的气温条件。要提高制种效果,剥蕾授粉工作必须在适宜的气温条件下进行。根据我们几年的试验结果,剥蕾授粉的适宜气温为15—28℃,而一般在12℃以上即可进行剥蕾授粉。气温低于12℃或高于30℃时都不宜进行剥蕾授粉。但在10℃时剥蕾授粉后气温继续上升,或在30℃时剥蕾授
After the spring, the Brassica napus into the pregnant bud bolting stage. At this point rape self-incompatible peel bud pollination seed production is about to work. However, how to do a good job of pollination and pollination in order to improve the seed production effect? According to several years of practice, we believe that we should master the following major technical aspects: 1, select the appropriate temperature conditions. To improve seed production, peel pollination work must be carried out under the appropriate temperature conditions. According to our several years of test results, peel bud pollination suitable temperature is 15-28 ℃, and generally above 12 ℃ to peel pollination. When the temperature is lower than 12 ℃ or higher than 30 ℃ are not suitable for peel pollination. But at 10 ℃ when the peel pollination continue to rise in temperature, or peel at 30 ℃ granted
