Abstract
Field experiment was conducted to study the effects of nitrogen, phosphorus, potassium deficiency and boron on N, P, K nutrition absorption and distribution, yield, quality of broccoli. The results showed that the plant accumulated more mineral nutrition during initial period of bud to curd intumescences period. In the whole growth stage, broccoli absorbed K most, then N, and P was least. N, P, K were distributed in leaves mostly, and then turn to curd. The content of N, P, K decreased 19.6%, 10% and 9.0% in leaves from bud period to harvest and the content of N, P, K in curd increased to 23.1%, 15.9% and 11.1% respectively in harvest period. The nitrogen, phosphorus and potassium deficiency decreased yield, vitamin C and finished product rate significantly. The treatment of adding boron increased finished product rate 4.8% than N, K, P treatment. The deficiency of nitrogen and sulfur decreased the glucosinolates significantly. Correlation analysis revealed that the yield was significantly correlated with N, K accumulation in plant and finished product rate was significantly correlated with P in plant.
