| 摘 要： | 探讨了在种衣剂中应用烯效唑防止油菜高脚苗及田间应用的效果.试验在油菜种衣剂中添加不同浓度的烯效唑并用于包膜3个油菜品种的种子,经室内试验筛选得到较适烯效唑浓度的种衣剂配方.田间试验表明,筛选出的含较适烯效唑浓度的油菜种衣剂Coat I包膜种子后可以有效防止油菜苗期的蚜虫危害,显著降低三叶期幼苗苗高、根颈长,显著增加叶龄和绿叶数;促进根颈粗和苗干重的增加.Coat I包膜处理还能改善油菜的经济性状,增加有效分枝数和单株角果数,提高了3个品种的籽粒产量,其中双72品种增产达18.9%.表明烯效唑通过种衣剂包膜种子处理能提高幼苗素质,有效解决油菜高脚苗问题,为油菜的高产稳产奠定基础.

| Abstract: | Rape seed coating agents with different concentration uniconazole were used for film coating and their effects on rape of three cultivars were studied. Optimal concentration of uniconazole in coating agents was selected out based on comparison of germination rate, chlorophyll content, seedling height and dry weight of the grown-up seedlings. Field experiments showed that the selected rape coating agent with optimal concentration of uniconazole (Coat I) effectively protected rape seedlings from damage by plant lice. It significantly reduced seedling height and main stem length, increased the number of leaves and green leaves at the three-leaf stage. It also had some effect in increasing width of main stem and seedling dry weight. Besides, the number of effective branches, pods per plant and seed harvest of three cultivars were also increased. Yield of Shuang 72 was increased by 18.9% as compared with the control which was not given film coating treatment. The results indicated that uniconazole could be used in preparation of seed coating agent in order to give rise to stronger seedlings of better quality and effectively resolve the problem of seedlings with high and slim main stems in rape production. |
