试验针对旱地深施化肥利用率不高的问题,从改进肥料类型与施肥技术入手,通过研究适于旱地应用的液肥品种与适期叶面喷施试验,表明新型多功能液肥具有提高叶水势、增强作物抗旱力、提高作物光合速率与水肥利用效率等多种功能,并在大旱之年,经在多种作物与大面积示范,可使单产提高213~5475kg/hm2(平均705kg/hm2),增产率达10%~30%(平均21.6%).

This paper reports on the new liquid fertilizer used and its proper foliar spray used in dryland based by improving type of fertilizer and application deal with the law use rate of chemical fertilizer.The result showed that the new multiperpors liquid fertilizer could reduce leaf water pretension,improve plant photosynthesis rate and water use efficiency,which increased yield of 10%-30% (mean 21.6%),and improve yield of 213-5 475kg/hm2(average of 705kg/hm2).
