田间药效试验表明 ,连续两次 (间隔 15 d)施用 8%甲哌可溶性粉剂 15 0～30 0 mg/ L,甘薯蔓长增长明显减慢 ,且浓度越高 ,增长越慢 ;甘薯产量增加了 12 .2 %～ 16.0 % ,在供试浓度范围内 ,浓度越高 ,增产越明显 ;室内生理实验表明 ,与对照相比用甲哌处理过的甘薯可溶性糖含量、淀粉含量无显著差异 ,说明甲派对甘薯品质无不良影响
Field efficacy trials showed that the application of 8% mechlorethamine soluble powder 15 0-30 0 mg / L twice a day (interval 15 d) significantly slowed the growth of sweet potato vine, and the higher the concentration was, the slower the growth was. The yield of sweet potato An increase of 12.2% ~ 16.0%, in the concentration range of the test, the higher the concentration, the more obvious the increase; Indoor physiological experiments showed that compared with the control, the soluble sugar content of sweetpotato treated with Metropole, starch content was not significant Differences, indicating that A sent to the sweet potato quality without adverse effects
