摘要
通过室内拌种法,研究了新型植物生长调节剂碧护与种衣剂比卡奇复配后不同温度下对小麦、花生、玉米三种作物出苗率的影响。结果表明,碧护药种与比卡奇复配,小麦、玉米、花生3种作物的最佳药种比分别为1∶500,1∶250,1∶500,与单剂及空白对照,小麦、玉米、花生在不同时期的出苗率分别可提高6.3%~18.6%,8%~12%,14%~22%,复配对三种作物的出苗率均有一定的增强作用,并在花生上的效果尤为明显。
The effect of seed dressing agent of Vitacat and Bikaqi, which are plant growth regulators, on e- mergence rate were discussed systematically in different temperature. The results showed that composite treatment cooperating Vitacat with Bikaqi could improve seeding emergence and promote healthy growth of wheat, peanuts and corn, and the optimum proportion of seed with agent are 1 : 500,1 : 250,1 : 500,re- spectively. As a contrast test, dressing seeds alone with Vitacat or Bikaqi were also done respectively. Compared with the single Vitacat or Bikaqi and the blank contral, the complex of Vitacat and Bikaqi had a distinctness influence on the seeding emergence rate and growth of the three crops. The emergence rate of wheat, peanuts and corn were increased by 6.3%~18.6% ,8%~12% and 14%~22%, respectively.
