玉米施用无机氮、磷、钾肥料,有一定的增产作用;在农肥的基础上施用,结果更明显.但各地试验结果并不一致,特别是磷、钾肥,有些地区增产,有些地区不增产,甚至减产.增产、减产的原因相当复杂,土壤特性,栽培水平都有密切的关系.本试验的目的是:结合莎车地区的土壤、自然条件与当前生产技术水平,以不同的比例,配合农肥施用无机氮、磷、钾的增产效果及对玉米生长、发育的影响.试验从一九五八年开始,到一九六一年为三年(其中,一九五九年中断).兹将结果整理分析于后,供参考.
The application of inorganic nitrogen, phosphorus and potassium fertilizers to maize had a certain increase in yield, and the results were more obvious when applied on the basis of agro-fertilizer, but the test results were inconsistent in various places, especially phosphorus and potassium fertilizers, increased yields in some areas, increased production in some areas, The reasons for increasing yield and reducing output are quite complex, and the soil characteristics and cultivation level are closely related.The purpose of this experiment is to combine the soil and natural conditions of Shache region with the current production technology level, with different proportions, Effect of Inorganic Nitrogen, Phosphorus, Potassium on Yield and Its Effect on Growth and Development of Corn. The experiment started from 1958 to 1961 and ended in 1961 (of which, it suspended in 1959) After finishing the analysis, for reference.
