加强果树用背负式手动精密施药器械的研制开发果树是农业化学防治的一大对象．如占水果栽培面积４０％～５０％苹果，每年至少要喷十多次药。其植保费用占总费用的４０％～５０％。因此如何不断研制开发出适合我国国情的果树用施药器械。其意义之重是不言而喻的。目得，我...

Strengthening the fruit tree Knapsack manual precision spraying device research and development of fruit trees is a major object of agricultural chemical control. If the fruit cultivation area of ​​40% to 50% of the apple, spray at least 10 times a year drug. The plant protection costs account for 40% to 50% of the total cost. Therefore, how to continuously develop and adapt to the application of fruit trees in China’s application of medical equipment. Its significance is self-evident. Eyes, I ...
