摘要
1989～1991年,在新疆塔额垦区春小麦喷灌生产田中,定位观测喷灌质量对春小麦生长和产量的影响。结果表明:喷灌均匀系数和湿润层深度是衡量喷灌质量的两个关键指标。影响两指标的主要因素是喷嘴工作压力和土壤容重。
In the years of 1989～1991,the fixed position observation and determination ofeffects of the qualities of sprinkler irrigation upon spring wheat growth and yields wasmade in spring wheat producing fields with sprinkler irrigation in TA-ER Land Recla-mation Area in XinJiang.The results showed that the uniform sprinkler coefficient andthe depth of wet layer are the two key indexes to evaluate the qualities of sprinkler irri-gation.The important elements affecting two indexes are the working pressure at nozzleand soil bulk density.
