花生的结果率很低,一般只有7—10%。不实花多,无效消耗大量养分,则造成秕果多,饱粒少,这一直是花生增产的障碍。为了解决这个问题,我们根据乙烯利对植物性器官的发步育作用及其已用于疏花、疏果方面的启示,在大田进行了乙烯利控制花生后期开花的试验和初观察。具体做法是:在见花后分三期(即7月6日,16日,26日)分别用1500ppm、1800ppm2000ppm以及2300ppm浓度喷施,供试品种为徐系1号、小区面积0.01亩,每次各处理喷药液一斤。重复两次,对照区喷水。结果第一次喷药后,10天之内累积开花量各处理比对照
The result rate of peanuts is very low, usually only 7-10%. Inaccurate, ineffective consumption of large amounts of nutrients, then the result is more fruit, less grain, which has been an obstacle to peanut production. In order to solve this problem, based on the phytotrophic effect of ethephon on plant organs and its enlightenment on the flower-thinning and fruit-thinning, we conducted experiments and preliminary observations on the flowering of perennial flowering of ethephon in the field. The specific method is as follows: After the flower is seeded in three phases (ie, on July 6, 16, 26) were sprayed with 1500ppm, 1800ppm2000ppm and 2300ppm concentration test varieties for Xu Department No. 1, plot area of 0.01 acres, each Each treatment spray a pound. Repeat twice, control area water spray. Results After the first spraying, the accumulated flowering within 10 days of each treatment than the control
