摘要：

为研究适宜西蓝花生产的化肥减量增效技术,提高种植效益,特开展田间试验,设置不施肥(CK)、常规施肥(W1)、化肥减量10%(在W1处理的基础上,下同)+微生物肥1 200 kg·hm-2(W2)、化肥减量20%+微生物肥1 500 kg·hm-2(W3)、化肥减量30%+微生物肥1 800 kg·hm-2(W4)4个处理,研究不同施肥模式对西蓝花产量、品质、肥料利用率,以及对土壤养分、酶活性的影响。结果显示,与单一施用化肥相比,适当的化肥减量配施微生物肥可提高西蓝花的生物性状和产量,改善品质,同时可以提高肥料利用率,及土壤养分含量和酶活性。运用隶属函数法对不同处理下西蓝花的产量品质进行综合评价,以W3处理的效果最好,经济效益最佳,具有推广应用价值。

Abstract:

In order to explore a suitable fertilization method, which could both reduce the input of chemical fertilizers and increase the efficiency of broccoli production, a field experiment was conducted to investigate the effects of different fertilization modes on the yield, quality, fertilizer utilization efficiency, and soil nutrients and enzymes activities of broccoli. There were four treatments: CK, no fertilizer applied; W1, conventional fertilization mode; W2, chemical fertilizer reduction by 10% (compared with the W1 treatment, the same as below)+microbial fertilizer 1 200 kg·hm-2; W3, chemical fertilizer reduction by 20%+microbial fertilizer 1 500 kg·hm-2; W4, chemical fertilizer reduction by 30%+microbial fertilizer 1 800 kg·hm-2. The results showed that compared with the conventional fertilization mode, application of appropriate reduction of chemical fertilizer combined with microbial fertilizer could improve the biological traits and yield of broccoli, improve its quality, increase the utilization efficiency of nitrogen, phosphorus, potassium fertilizers, and enhance the soil nutrients content and enzymes activities. The subordinate function method was used to comprehensively evaluate the characteristics and quality of broccoli under different fertilization modes, and the W3 treatment exhibited the best performance, as well as the highest economic benefit, which could be promoted in agricultural production.

Key words: broccoli, chemical fertilizer reduction, yield, quality, soil nutrient
