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
