为探明种衣剂对免耕直播油菜幼苗生长、苗体酶活性及氮、磷、钾、硼等含量的影响,用丸化型种衣剂WHY-11和薄膜型种衣剂YCY-11分别包衣杂交油菜和常规油菜种子,进行免耕直播栽培试验。结果表明,与对照相比,丸化型种衣剂和薄膜型种衣剂包衣处理后,油菜防控病虫害的能力分别提高了32.73%～79.44%和10.91%～70.61%,油菜幼苗茎粗分别提高了7.96%～11.54%和3.45%～6.90%,叶面积分别提高4.21%～38.31%和20.56%～21.08%,鲜重分别提高了11.84%～46.86%和18.80%～25.83%;而高脚苗率分别降低了5.66%～10.23%和15.11%～18.90%;苗体氮、磷、钾、硼含量分别提高了7.44%～19.22%和0.95%～5.52%,2.0%～2.8%和18....

To explore the effects of seed-coating agents on seedling growth,some enzyme activities and contents of nitrogen（N）,phosphorus（P）,potassium（K） and boron（B） of rape under the conditions of no-tillage and direct-seeding,experiments were conducted by using no-tillage and direct-seeding cultivation with hybrid and conventional rape seeds coated with seed pelleting agent WHY-11 and seed filming agent YCY-11,respectively.Results showed that the prevention rates to main diseases and insect pests during seedlings of coating treatment rapes with...
