摘要
本项研究结果表明，应用乙缩调节剂（乙烯利＋缩节安）除去棉花早蕾可减轻烂铃病的发生。处理区与对照区相比平均防效５８．０１％，皮棉平均增产１９．６２％，其中乙烯利１５００ｐｐｍ＋缩节安１００ｐｐｍ，亩施药液２５公斤，喷棉株周围，防病增产效果最佳。
The
results showed that cotton boll rot could be decreased effectively due to removing early bud by
spraying a regulatory agent EMC,(ethephon + empiquat chloride). camparing with the check,
the treatments had an average control efficiency of 58.01%and the average increasing rate of
ginned cotton output being 19.62%, Among those treatments,1500ppm ethephon+100ppm
empiquat chloride with the dosage of 25 kilograms per mu and spraying just round the plants
showed the optimum effect of controlling boll rot and in-creasing output.
