| 摘 要： | 采用田间试验方法研究了不同氮钾水平和配比对结球甘蓝产量、品质参数的影响。结果表明,氮肥和钾肥以及适宜配合施用可显著提高结球甘蓝产量和养分生产效率的提高。钾肥可提高结球甘蓝Vc、糖分的含量,减缓不合理施氮带来的负面影响。氮肥可提高结球甘蓝氨基酸含量,氮、钾肥料都可提高必需氨基酸的营养价值。Vc和糖分含量与叶球含氮量成负相关,与含钾量成正相关。充足的钾素供应和合理的氮钾配比是保证蔬菜优质高产的关键。

| Abstract: | The field trials were conducted to study the effect of different N and K rates on the yield and quality of cabbage(Brassica oleracea var. capitata). The results indicated that the N, K and their proper combined application could significantly increase the cabbage yield and nutrient utilization efficiency. K fertilizer could remarkably increase the content of Vc and sugar content and alleviate unfavorably effect of unsuitable N application. Nitrogen could increase the content of amino acid, N and K increased nutritional value of essential amino acid. The Vc and sugar contents were negative correlation with N content in cabbage head, and positively with K content. The adequate K supply and optimum N and K combination could ensure the high-quality and high-yield production of vegetables. |
