微量元素水溶肥料在油菜上的应用效果

Study on Application Effect of Trace Elements Water-soluble Fertilizers on Rape

[目的]研究微量元素水溶肥料在油菜上的应用效果,为油菜科学施肥提供参考。[方法]在油菜上喷施"翠兰春牌"微量元素水溶肥料,与清水对照、空白对照(当地习惯施肥)相比较,分析微量元素叶面肥对油菜抗病能力、经济性状和产量的影响。[结果]在油菜上喷施"翠兰春牌"微量元素叶面肥,可明显增强油菜的抗病能力,降低菌核病株率和发病指数,发病株率分别较对照组低18.18%和17.53%,发病指数分别较对照组低5.68和7.73;增产效果显著,实际产量分别高出对照组240.0、363.5 kg/hm2,增产9.60%;经济效益明显,与对照组相比,分别增加纯收入924、1 418元/hm2。[结论]"翠兰春牌"微量元素水溶肥料适合在油菜作物上推广使用。

[ Objective ] The study aimed to researched the effect of water soluble fertilizer on rape, in which trace elements, provided a reference for the scientific fertilization. [ Method] ＂Cuilanchun＂ water soluble fertilizer was sprayed on rapes, compared with fresh water control and blank control, the influence of disease resistance, economic characters and the yield on rapes were analyzed. [ Result] The results showed that ＂Cui- lanchun＂ can enhance disease resistance, reduce sclerotinia sclerotiorum strain rate and disease index, the disease incidence lower than that of fresh water control and blank control 18.18% and 17.53%, and disease resistance lower than that of fresh water control and blank control 5.68 and 7.73, respectively ; stimulation effect was obvious, it can actual output was higher than that of CK 240.0,363.5 kg/hm2 , respectively, in- crease rate 9.60% ; increased net income by 924 and 1 418 yuan/hm2 with obvious economic benefit. [ Conclusion] ＂Cuilanchun＂ is fit to promo- ting on rape.
