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。

Abstract:

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 WHY-11 and WHY-11 increased by 32.73%-79.44% and 10.91%-70.61%, compared with uncoated controls, respectively. The cauline basilar width increased by 7.96%-11.54% and 3.45%-6.90%; The leaf area increased by 4.21%-38.31% and 20.56%-21.08%; The fresh weight increased by 11.84%-46.86% and18.80%-25.83%; The rate of high hypocotylar seedling decreased by 5.66%-10.23% and 15.11%-18.90%; The contents of N, P, K and B increased by 7.44%-19.22% and 0.95%-5.52%, 2.0%-2.8% and 18.74%-38.83%，3.57%-4.49% and 2.85%-4.30%, 7.82%-9.07% and 9.05%-10.72%, respectively; The activities of peroxidase (POD), catalase (CAT) and superoxide dismutase (SOD) increased by 17.64%-44.56% and 27.61%-33.05%， 85.54%-86.46% and 19.62%-66.56%, 8.46%-19.35% and 14.99%-27.73%, respectively. Those results showed that two seed-coating agents not only could promote seedling growth, increase seedling resistance to adverse environments, but also could enhance seedling qualities of no-tillage and direct- seeding rapes. These effects, however, were different on hybrid and conventional rapes. The general effects of seed pelleting agent were better than those of seed filming agent.
