化肥施用对绿芦笋产量和品质的影响

Effect of Chemical Fertilization on Yield and Quality of Green Asparagus

在大田条件下,研究了不同氮磷钾肥对绿芦笋产量及品质的影响。结果表明,绿芦笋支数、单支质量以及总产量均以NPK处理最高;PK,NK以及NP处理的芦笋支数、单支质量均不同程度降低,最终导致减产。芦笋粗蛋白、粗脂肪、粗纤维、可溶性蛋白、可溶性糖以及不同矿质元素含量均以NPK处理最高。可见,平衡的养分供给不仅可以提高绿芦笋产量,而且还可以有效改善芦笋的品质。

A field experience was conducted to study the effect of NPK fertilization on yield and quality of green asparagus.The result showed that the branches of green asparagus,weight of per branch and yield of green asparagus in NPK treatment had the maximum values among those five treatments.The branches of green asparagus and weight of per branches in treatment of PK,NK and NP were much lower than NPK at different level.The content of crude protein,soluble protein,soluble sugar and content of mineral element in NPK treatment were much higher than in the other treatments.We concluded that balanced nutrient applications could not only increased yield,but also improved quality of green asparagus.
