近几年来,由于除莠剂的大量采用,喷雾作业已成了一项重要的生产环节。所喷药液一般都价格昂贵,用量很少。所以喷量要务求精确、均匀。否则不但损失药液,浪费了宝贵的生产资金,而且易形成药害,造成减产甚至绝产。本文想就机械上如何保证喷量准确、均匀谈几点粗浅的意见。 In recent years, due to the large use of herbicides, spray operations have become an important production link. The spray liquid is generally expensive, dosage is small. So to be precise and uniform spray. Otherwise, not only will the chemical liquid be wasted, precious productive capital will be wasted, but it will also easily lead to injury and harm, resulting in a reduction in output or even an absolute loss. This article would like to ensure that the accuracy of the spray on the machine, talk about a few superficial opinions.
