化肥已成为泽普县农业增产的重要技术措施,每年用量5000吨(标准肥)以上。为进一步摸索化肥合理施用技术,按全国化肥试验网统一设计,结合泽普县情况,我们作了化肥田间试验。 一、概况 泽普县位于叶尔羌河冲积扇上,地形较为平坦,海拔高程1215—1490米,耕地土壤为灌淤土和潮土,土层深厚,一米深土层为轻壤—中壤,土壤母质为灌淤物,冲积物,试验土壤理化性状:0—20厘米上层的有机
Fertilizer has become Zepu County, an important measure of agricultural production, annual consumption of 5,000 tons (standard fertilizer) above. To further explore the rational use of fertilizers technology, according to the National Fertilizer Experimental Network unified design, combined with the situation in Zepu County, we made a field experiment of fertilizer. First, an overview Zepu County is located in the Yarkant River alluvial fan, the terrain is relatively flat, elevation 1215-1490 meters, arable land for irrigation silt and Chao soil, deep soil layer, one meter deep soil layer is light soil - soil, soil The parent material for the irrigation silt, alluvial, test soil Physical and chemical properties: 0-20 cm above the organic
