Abstract:Where the vegetable fields were according to different fertility levels of Boron and Molybdenum in Pearl River Delta.In this paper,the test data of Boron and Molybdenum application amount,the soil available nutrient of Boron and Molybdenum,the relative yield of vegetables and Boron and Molybdenum uptake rate were analyzed statistically,and the regression equation was also acquired.Base this,the index of soil available Boron and Molybdenum and the application Boron and Molybdenum rate were obtained.(1)According to the model were obtained the sufficiency and deficiency range which the soil effective Boron were respectively<0.05 mg/kg、0.05~0.20 mg/kg、0.20~0.45 mg/kg、0.45~0.65 mg/kg、>0.65 mg/kg,which the relative product were respectively 50%、50%~75%、75%~90%、90%~95% and>95%,The proposed application Boron rate of vegetables were respectively 75g/667m2、50~75 g/667m2、32~50g/667m2、26~32 g/667m2、0~26g/667m2。(2)According to the model were obtained the sufficiency and deficiency range which the soil effective Molybdenum were respectively <0.01 mg/kg、0.01~0.07 mg/kg、0.07~0.24 mg/kg、0.24~0.35 mg/kg、>0.35 mg/kg.The proposed application Molybdenum rate of vegetables were respectively 12.5g/667m2、10.5~12.5 g/667m2、9.5~10.5 g/667m2、9.0~9.5 g/667m2、0~9.0 g/667m2。
