摘要
旱地节水型播种机可在播种施肥的同时进行施水作业，达到保苗节水的目的。为研究此类机具的施水方案、载水量、施水量、水流量与土壤环境状况的关系，通过室内试验和２ＢＦＳ－３型施水硬茬播种机的田间测试，分析了在粘壤土上作业时施水量与出苗状况的关系，还对施水播种中遇到的施水范围、播种深度、播种均匀生、工作部件适应性。
Water saving sowing machines for dryland can conduct the watering operation as sowing and fertilizing, with which the objective of seedling prevention and water saving can be achieved. In order to study the relationship of water applicating design scheme,water load capacity, water applacting capacity and water flowing capacity with soil environment, both on the basis of the indoor experiments and of field tests with 2BFS-3 water applicating sowing machine, the relationship between water applicating capacity and seedling emergence on clay soil has been analyzed. Also, waterapplicating scope, sowing depth, sowing evenness, working parts adaptability and management mechanism of farming machinery and water conservancy during water applicating and sowing are discussed in this paper.
