In the cotton film covered nutrition bowl nursery, seedling bowl is to increase the quality of cotton seedlings one of the measures. Before transplanting timely removal bowl (moderate injury main root), can effectively inhibit the growth of the shoot, promote root development and shorten the field huanmiao period. However, moving the bowl consume a large amount of work loss bowl more difficult to implement large areas. CCC, plant stalks stubby, developed root system, control leggy. In this paper, CCC, Pix and other growth inhibitors on the effectiveness of cotton seedlings, and moving mortar Dunmiao made a comparison, the purpose is to observe whether the effect of spraying pots Dunmiao.
