采用田间试验研究了6种肥料组合对不同采收期茎瘤芥茎叶产量、营养品质和叶片养分的影响。结果表明,不同肥料组合中2个采收期除钙镁磷氯钾处理明显降低茎瘤芥茎叶产量(22.8%～54.6%)外,其余各处理对茎瘤芥茎叶产量有明显提高作用,以专用肥I(有机无机型)对茎瘤芥茎重提高作用最大。各处理除钙镁磷氯钾对茎营养品质主要表现为提高作用,其余处理可提高氨基酸和粗蛋白含量,降低Vc、可溶性糖、磷和钾含量。专用肥I处理的茎瘤芥茎营养品质整体上优于专用肥II(无机型)处理。普钙硫钾与磷铵硫钾处理的Vc含量差异不明显,可溶性糖和氨基酸含量以普钙硫钾为优,但粗蛋白、磷和钾含量以磷铵硫钾处理较好;普钙硫钾与普钙氯钾处理相比,Vc含量差异不明显,前者可溶性糖和氨基酸含量较优,但粗蛋白、磷和钾含量以普钙氯钾处理较好。除钙镁磷氯钾处理外,各肥料组合处理提高茎瘤芥叶片全氮含量,降低全钾含量,提高收获期全磷含量,叶片N/P,N/K,K/P变化幅度小。
Field experiments were conducted to study the effects of six fertilizer combinations on the yield, nutritional quality and leaf nutrient contents of stem and mustard in different harvesting periods. The results showed that the yield of stem and mustard stems and leaves increased obviously in all the treatments except Ca, Mg, K, K and K in two harvest periods of different fertilizer combinations significantly reduced the yield of stem and mustard stems and leaves (22.8% -54.6%) , With special fertilizer I (organic and inorganic type) on the tumor stem mustard heaviest role in raising the most. The treatment of calcium, magnesium, phosphorus, potassium and potassium on the main nutritional quality of stems to enhance the role of the rest of the treatment can increase the amino acids and crude protein content, reduce Vc, soluble sugar, phosphorus and potassium content. Specialized fertilizer I processed stem mustard stems nutritional quality overall better than the special fertilizer II (inorganic type) treatment. There was no significant difference in the content of Vc among the contents of P, K, S, K, K and K, but the contents of soluble sugar and amino acid were better than P, K and K. However, the contents of crude protein, P and K were better treated by ammonium, There was no obvious difference in Vc content between potassium and normal calcium chloride treatment. The content of soluble sugar and amino acid in the former was better, but the content of crude protein, phosphorus and potassium was better treated with CaCl2 and K2O. In addition to calcium, magnesium, phosphorus, potassium and potassium treatment, the combination of fertilizer to increase the total nitrogen content of the stem mustard leaf, reducing the total potassium content and increase the total phosphorus content during harvest, leaves N / P, N / K, K / P small changes.
