氮磷钾施用量对高山甘蓝产量及品质的影响
Effect of Chemical Fertilizer Applying Quantity on Yield and Quality of High Mountain Cabbage
摘要
Abstract
Taking'Jingfeng No.1'as experiment material,this paper studied the effect of applying different amount of nitrogen(N),phosphorus(P)and potassium(K)chemical fertilizer,on the yield,quality and economic benefit of cabbage(Brassica oleracea L. var. capitata L.)planted in high mountain at western Hubei Province by field experiment method.The results showed that the highest yield was obtained by applying 375 kg·hm-2 N fertilizer,which was 9.44% and 2.68% higher than that of 150 and 225 kg·hm-2 N treatment, respectively.The cabbage yield of applying 180 kg·hm-2 P fertilizer was 17.56% and 7.27% higher than 0 and 135 kg·hm-2 P treatment,respectively.The yield of applying 525 kg·hm-2 K fertilizer was 35.08% and 15.55%higher than 0 and 225 kg·hm-2 K treatment,respectively.Therefore,increasing N,P and K fertilizer input could increase the ratio of free amino acid content,and the total acid content was decreased.At the same time, there existed a tendency of increasing the accumulation of nitrate.Increasing the application of K fertilizer could also increase the VC content of cabbage.In conclusion,the recommended N,P and K fertilizer application were 225-300 kg·hm-2,180-225 kg·hm-2 and 225-300 kg·hm-2 in mountainous areas at western Hubei Province.关键词
