化学药剂在农田上的施用,是实现农业现代化的重要措施之一。化学药剂的喷洒,须由一整套喷雾机械来完成。随着化学药剂的大面积施用,使喷雾机械的数量和品种不断增加,研制使用技术,作业水平不断提高。但由于我国喷雾机械的发展历史较短,喷雾作业还不够广泛,因此在喷雾机械的研制,作业管理,以及与此相关的人们在认识方面,都存在着一定的差距。国营农场使用化学药剂,已有近二十年的历史,施用范围和面积逐年扩大,由最初24—D小麦叶面杀草,发展到当前大
The application of chemical agents in farmland is one of the important measures to realize agricultural modernization. Chemical spraying, to be a complete set of spray machinery to complete. With the large-scale application of chemical agents, the number and types of spray machines are continuously increasing. Research and application technologies are used to improve the operation level. However, due to the short history of the development of spray machinery in our country, the spraying operation is still not extensive enough. Therefore, there is a certain gap in the development of spray machinery, operation management and people who are concerned with this problem. State-owned farms use chemical agents, has nearly 20 years of history, the scope and area of the expansion has expanded each year, from the initial 24-D wheat leaf herbicide, the development of the current large
