Abstract

Abstract: Field experiment was carried out to study the effects of nitrogen （N）, phosphorus （P） and potassium （K） amount on yield, quality and nutrient use efficiency of broccoli. The results showed that with the increase of N application （240~480 kg/hm²）, the yield, biomass and dry matter of broccoli increased first and then decreased, and the highest N application rate was 330~405 kg/hm². When the amount of N, P and K exceeded 330, 135 and 255 kg/hm²,respectively, the effect of yield improvement was limited. N application with 330~405 kg/hm² could obtain higher N, P and K accumulation. When P and K application exceeded 135 and 255 kg/hm²,respectively, the N accumulation of plant reduced, but the effect on P and K accumulation was not significant. Nitrogen use efficiency and agronomic use efficiency reached 43.10%~47.66% and 16.25~16.72 kg/kg respectively with 240~405 kg/hm² of N application. Nitrogen application increased nitrate accumulation in broccoli, but decreased vitamin C content, while sugar-acid ratio and ash content decreased first and then increased. In a word, broccoli can obtain better yield and quality and nitrogen use efficiency when the amount of P and K was 135 and 255 kg/hm²,respectively, and with the 330~405 kg/hm² of N application.

Key words: yield, quality, nutrient accumulation, nitrogen use efficiency, agronomic use efficiency
