吊瓶精准输液技术对芒果产量的影响

采用吊瓶精准输液技术，在芒果树开花到成熟期按树体大小定量向树杆木质部注射营养液，以确定对芒果产量的增产效应，结果表明：芒果果数可增产23.85%，单果重可增产22.77%，总产量可增产52.06%，其产投比为3.38:1，是对照产投比（2.29:1）的1.48倍。通过定量分析和计算机模拟的方法推导出芒果精确施肥用药量的数学模型为?=5.15383(D)3.09674(g)，对吊瓶输液技术导致芒果抗旱丰产的原因进行分析及讨论。

The Infection of the Tree Suspend Bottle Accurate Transfusion Technology on Mango Output

The increase production effect of mango was confirmed by using the tree suspend bottle accurate transfusion technology with injecting nutrition liquid into tree staff xylem from florescence to autumn.The test result indicated:the mango fruit number,single fruit weight and chief output were increased by 23.85%,22.77% and 52.06%.The 0utput/investment (3.38:1) of chief output was 1.48 times than comparison (2.29:1).The math model (y=5.15383(D)3.09674(g)) of extractive transfusion drug and fertilization volume in the mango was deduced using quantitative analysis and computer simulate method.In the paper,the causes of mango increase product were analyzed and discussed.
