Method for increasing seeding rate of robinia pseudoacacia seed producing seed trees

The invention relates to the technical field of robinia pseudoacacia cultivation, in particular to a method for increasing the seeding rate of robinia pseudoacacia seed producing seed trees. The method specifically comprises the steps of shaping and trimming, and a trimming method comprises the steps that lateral branches at the outermost ends of the robinia pseudoacacia seed trees at the seedingstage are divided into seeding branches and growing branches; the seeding branches are trimmed again in the middle ten days of April, and good branches of the growing branches are subjected to full-branch cultivation in the first ten-day period of May; next year, alternating of the seeding branches and the growing branches is carried out. According to the method, alternate seeding and trimming operation are combined, so that the seeding rate is increased, the seed yield is obviously increased, and the seed quality is obviously improved. 本发明涉及刺槐育种技术领域，尤其涉及种提高刺槐采种母树结种率的方法，所述方法具体包括整形和修剪，修剪的方法为：将结种期刺槐母树的最外端侧枝分为结种枝和生长枝；4月中
