| 摘 要： | 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18.74%~38.83%，3.57%~4.49%和2.85%~4.30%，7.82%~9.07%和9.05%~10.72%；苗体内过氧化物酶（POD）、过氧化氢酶（CAT）和超氧化物歧化酶（SOD）活性分别提高了17.64%~44.56%和27.61%~33.05%，85.54%~86.46%和19.62%~66.56%，8.46%~19.35%和14.99%~27.73%。表明2种种衣剂具有促进油菜幼苗生长、增强抗逆性、提高苗素质等作用，其作用程度在杂交品种和常规品种间存在一定差异；丸化型种衣剂的综合作用效果优于薄膜型种衣剂。 |
