由于尼龙育苗移栽棉种植面积扩大,棉花生育提早,早桃增加,到8月中下旬便进入吐絮期。此时,正是我县秋雨连绵的连阴雨阶段。据1959～1984年26年的气象资料,8月中旬到9月下旬的51天中,平均雨日为23天,占45.1％。雨日雨量多,田间湿度大,加上棉花株高叶茂,下部郁闭严重,有利铃病滋生,导致烂铃。一般年景单株烂铃两个左右,多的超过3个,部分棉田烂铃三分之一。为了减少损失,在1980年前,我们提出采烂铃的措施,要求发现烂铃及时采摘,结果“采了烂的,烂了好的”,收效甚微。1981年我们在直塘乡青秧村改采烂铃为采黄铃,当年初见成效。到1983年,全村推开,效益显著,现已被广大棉农视为增产增值的重要手段。 Due to the expansion of nylon seedling transplanted cotton planting area, cotton growth earlier, early peach increased to mid to late August will enter the boll opening period. At this point, it is my county even the rainy autumn rainy phase. According to the weather data from 1959 to 1984 for 26 years, the average rainfall day was 23 days, accounting for 45.1% of the 51 days from the middle of August to the end of September. More rainfall on rainy days, field humidity, coupled with high leafy cotton plant, the lower canopy serious, beneficial bell disease breeding, resulting in bad bell. General years of single plant two bad bell, more than 3, one-third of the cotton ring rotten bell. In order to reduce losses, before 1980, we put forward measures to collect rotten bells and asked for the timely detection of rotten bells. As a result, “badly picked and bad ones” were achieved with little success. In 1981, we changed the rotten bell to pick the bell in Qingyang Village, Zhitang Township. By 1983, the whole village had been opened with significant benefits. It has now been regarded by the vast number of cotton farmers as an important means of increasing production and increasing value.
