甘蔗种苗应用化学药剂和植物生长调节剂浸泡6～24小时,能促进甘蔗萌芽,明显地提高出苗率和蔗苗生长,经试验研究,表现最好的7种药剂及使用浓度是:0.1ppm 油菜素内酯、50～900ppm 乙烯利、2%熟石灰、0.25%苛性钾、200ppm 黄腐酸、20ppm 精氨酸和1%硝酸钙。与清水浸种比较,其中油菜素内酯和乙烯利处理达极显著差异,熟石灰处理达显著差异。由于试验中所用的苛性钾、硝酸钙、精氨酸均系 Sugarcane seedling application of chemical agents and plant growth regulators for 6 to 24 hours, can promote sugarcane sprouting, significantly improve the emergence rate and seedling growth, the experimental study, the performance of the best 7 kinds of agents and concentrations are: 0.1ppm Brassinolide, 50 to 900 ppm ethephon, 2% hydrated lime, 0.25% caustic potash, 200 ppm fulvic acid, 20 ppm arginine, and 1% calcium nitrate. Compared with the soaking of fresh water, the brassinolide and ethephon treatment reached the extremely significant difference, and the slaked lime treatment reached significant differences. As the caustic potash used in the test, calcium nitrate, arginine are all
