花期协调是玉米制种的技术关键,目前生产中还只是利用查测叶龄而后采用促慢、控快、剪苞叶、辅助授粉等办法进行被动补救。这些办法需增加较大的投入,效果却往往事倍功半。

花期协调是玉米制种的技术关键,目前生产中还只是利用查测叶龄而后采用促慢、控快、剪苞叶、辅助授粉等办法进行被动补救。这些办法需增加较大的投入,效果却往往事倍功半。笔者从分析亲本不同生育阶段天数与水热条件的相关关系入手,建立任一
Flowering coordination is the key technology of seed production in maize. At present, the production is only used to detect the leaf age and then use the method of slowing down, controlling fast, cutting the leaves and assisting with pollination. These measures need to increase a larger investment, the effect is often less effective. The author from the analysis of the different stages of the growth of the parents of the relationship between the number of days and hydrothermal conditions, the establishment of any
