Effects of Different Concentrations of Nano-Selenium Fertilizer on Yield,Quality and Selenium Content of Broccoli
Taking"Naihanyouxiu"of broccoli variety as experimental material,the effects of two kinds of nano-selenium fertilizer spraying on the yield,quality,active components and selenium content of broccoli were studied.The results showed that suitable concentration of nano-selenium fertilizer can significantly improve the quality and yield of broccoli,among which the yield,quality index and selenium content of Zhenxi 500 times solution were significantly higher than spraying the same amount of water treatment(CK),and the yield and selenium content were 66.7％and 343％higher than CK,respectively.The yield and selenium content of broccoli treated with 1000 times of fish peptide and selenium were 55.6％and 146％higher than CK,respectively.It can be seen that the suitable concentration of nano-selenium fertilizer spraying on the leaf surface can significantly promote the yield and quality of broccoli.
