摘要
三年试验结果得出 ,当芒果产量为 18668kg/ hm2 ,果实养分吸收量为 N2 2 .4 kg/ hm2 ,P2 O59.0 kg/ hm2 ,K2 O 4 4 .7kg/ hm2 ,Ca 3.2 kg/ hm2 ,Mg 3.0 kg/ hm2 ,S 2 .3kg/ hm2 ,养分吸收比例为 :1∶ 0 .4 0∶ 2 .0 0∶ 0 .14∶ 0 .13∶ 0 .10。芒果适量配施氮、磷、钾、镁和硫肥能获得较高效益 ;适宜施肥量为 N34 2 kg/ hm2 ,P2 O510 7kg/ hm2 ,K2 O2 74 kg/ hm2 ,Mg34 kg/ hm2 ,S34 kg/ hm2 。
Results of three\|year in Mango trails showed that nutrient absorption rates of fruit with a yield of 18668 kg/hm 2 are N 22.4 kg/hm 2,P 2O 5 9.0 kg/hm 2,K 2O 44.7 kg/hm 2,Ca 3.2 kg/hm 2,Mg 3.0 kg/hm 2 and S 2.3 kg/hm 2,which the nutrient absorption ratio appeared to be 1∶0.40∶2.00∶0.14∶0.13∶0.10.The appropriate application rates recommended are separately N 342 kg/hm 2,P 2O 5 107 kg/hm 2,K 2O 274 kg/hm 2,Mg 34 kg/hm 2,S 34 kg/hm 2.
