不同复合肥施用水平对保护地甜椒生长和产量的影响

Effects of Different Compound Fertilizer with Different Levels on Growth and Yield of Sweet Pepper in Protected Field

[目的]为复合肥的合理施用提供科学依据。[方法]以甜椒9133为试材,采取田间小区试验方法,采用3种不同配比复合肥,设3个施用水平,研究不同复合肥及其施用量对甜椒9133的生长和产量的影响。[结果]3种复合肥对甜椒9133的株高、茎粗具有明显的促进作用,均随施用量的增加而增加,但当施用量到达一定水平时,产量随施用量增加而减少,施肥效益降低。[结论]甜椒9133在中等土壤肥力条件下,适当提高钾的施用比例,有助于提高甜椒产量。

[Objective] The study aimed to provide references on compound fertilizer.[Method] With Sweet pepper 9133 as the tested materials,took field plot as the method,3 treatments of different compound fertilizer and 3 fertilizer ratios were set up to study the effects on growth and yield.[Result] There were promoting effects of compound fertilizer with different levels on plant height and stem diameters,increasing along with increase of fertilizer.When the level reached a certain level,yield reduced with the application.[Conclusion] The optimum application was medium soil fertility and improved the potassium ratio would helpful to pepper yield.
