棉花生产中常出现蕾铃大量脱落现象,对产量的影响很大。造成蕾铃脱落的原因是多方面的,下面就蕾铃脱落的规律、原因及应对措施,进行一下分析,供大家参考。一、蕾铃脱落的一般规律1、蕾铃脱落的比例。在蕾铃脱落中,落蕾与落铃的比例,总的趋势是落铃率高于落蕾率,其比例约为3∶2。但棉花前期遭受病虫害、干旱、水涝时,落蕾率大于落铃率。2、蕾铃脱落的日龄。现蕾以后11-20天的脱落最多,20天以上的大蕾脱落的较少。棉铃开花
Cotton production often appear a large number of buds off phenomenon, a great impact on the yield. Rayleigh shedding caused by many reasons, the following principles of falling off the bell, the reasons and measures to carry out some analysis for your reference. First, the general rule of the falling buds 1, the proportion of falling buds. In the buds falling off, the ratio of falling buds to falling bell, the general trend is that the falling boll rate is higher than the falling bud rate, and the ratio is about 3: 2. However, early cotton suffered pests, droughts and waterlogging, the rate of falling buds is greater than the rate of falling bolls. 2, the age of the buds fall off. 11-20 days after budding off the most, less than 20 days off the big buds. Cotton boll flowering
