在棉花杂交制种环节中,如何提高授粉工效和质量,是降低制种成本,提高制种产量的关键之一.而目前棉花制种授粉的方法有毛笔涂抹、指套涂抹、小瓶法、套管法、花对花和昆虫授粉等,各有利弊.下面据笔者在多年制种实践中发明研制的一种插入式授粉器介绍给大家.一、原理及制作(一)原理 该授粉器即利用特制的授粉膜做成的授粉器,倒插棉花花柱,使柱头通过足量的花粉层,达到充分授粉之效果.其特征是授粉膜为中央呈辐射状开口的弹性膜.
How to improve pollination efficiency and quality in cotton hybridization is one of the key points to reduce the cost of seed production and increase the seed yield.At present, the pollination method of cotton seed production includes brush smearing, finger coating, vial method, The law, flowers and insects, pollination, and so on, each has its own advantages and disadvantages.According to the author in the years of seed production and invention developed a plug-in introduced to everyone. First, the principle and production (A) Using a special pollination film made of pollinators, inverted cotton style, the stigma through the pollen layer enough to achieve the full effect of pollination, characterized in that the pollination film is a radial central opening of the elastic membrane.
