种子丸粒化对棉花生长发育的影响

The Effects of Cottonseed Pelletizing on Cotton Growth and Development

研究了种子丸粒化技术对棉花出苗率、苗期病害、保苗效果及生长发育的影响。结果表明,棉花种子丸粒化处理出苗率高出供试种衣剂处理4～16个百分点,苗期发病率低于供试种衣剂处理1.94～7.54个百分点,苗期死苗率低2.87～9.41个百分点,棉花苗期相对保苗效果高44.0％～150.4％;棉花苗期病茎长度低于供试种衣剂处理0.21～0.44cm;单株伏前桃数较供试种衣剂处理增加0.59～1.46个,吐絮期提前4～6d。

The paper studied the effects of pelletization technology on some cotton physiological properties including rate of germination, death rate, seedling protection and the upgrowth during the seedling stage. The results showed that; compared with the seed-coating treatment, the germination rate, seedling protection and the number of single cotton buds increased 4% - 16%, 44. 0%-150. 4% and 0. 59% - 1. 46% respectively; the disease rate, the seedling death rate and the ill-stemed length dureased 1. 94%-7. 54%, 2. 87%-9. 41% and 0. 21%-0. 44%respectively. The date of boll-opening stage is shortened by 4-6 days.
