丰产素是广谱性植物生长调节剂,已广泛应用于水稻等多种作物。为探讨其在玉米栽培上的应用,笔者于1992年早、晚两季分别对甜玉米进行种子浸种和花期喷雾试验。结果表明2000、3000、4000、5000倍浓度处理过的超甜20号种子,其发芽率和发芽势都明显优于对照(清水浸种),其中以3000倍液处理的效果较好,发芽率为93.4%,较对照的89.6%提高3.8个百分点;发芽势也明显增强,72小时的发芽率为85.1%。较对照的79.2%增加5.9个百分点。对发芽后的种子分别进行清水育苗(在培养皿里进行)
Abundance is a broad-spectrum plant growth regulator, has been widely used in rice and other crops. In order to explore its application in maize cultivation, the author conducted seed soaking and flowering spray experiments on sweet corn in early and late 1992 respectively. The results showed that the 2000, 3000, 4000, 5000 times the concentration of super sweet 20 seeds, the germination rate and germination potential were significantly better than the control (water soaking), of which 3000 times the liquid treatment is better, the germination rate 93.4%, increased by 3.8% compared with the 89.6% of the control; the germination potential also increased obviously, and the germination rate in 72 hours was 85.1%. 79.2% more than the control increased by 5.9 percentage points. Seeds after germination were nurtured seedlings (in Petri dishes)
