利用“3414”田间肥效试验,研究N、P、K肥对大白菜晋菜1号产量、经济效益的影响,并分析了肥料利用率。结果表明,合理施用N、P、K肥能产生显著的增产增收作用,试验表明:合理配施N、P、K肥,大白菜晋菜1号增产量最高达6 417 kg/hm2,增加的纯收入为18 148.5元/hm2。在生产中不能盲目加大肥料用量,要根据土壤肥力状况及大白菜对养分的需求规律,做到N、P、K肥合理配施,以减少肥料损失,同时加强土壤培肥至关重要。
The effects of N, P and K fertilizers on the yield and economic benefit of Chinese cabbage Jincan No.1 were studied by using “3414” field fertilizer efficiency test. The utilization rate of fertilizer was also analyzed. The results showed that rational application of N, P and K fertilizers could produce significant effects of increasing yield and increasing yield. The results showed that the yield of Chinese cabbage Jin Cai 1 was up to 6 417 kg / hm 2 with the rational application of N, P and K fertilizer, Net income of 18 148.5 yuan / hm2. In the production can not blindly increase the amount of fertilizer, according to the status of soil fertility and nutrient requirements of Chinese cabbage law, so N, P, K fertilizer rationally to reduce fertilizer losses, while strengthening soil fertility is essential.
