为了掌握不同化肥品种在当地的土壤气候条件下,对不同作物的增产效果及其经济合理的施用技术,以便指导生产,我们从1961年起,连续三年进行了国产化肥的试验研究工作。现就棉花的有关试验资料总结如下。一、试验方法试验地位于塔里木河上游北岸地区的二级阶地,土壤为荒漠胡杨林土,质地为砂壤,灌溉地,地下水位2—3米,脱盐情况较好,肥力中等,全氮量为0.09—0.11％.全磷量(P_2O_5)为0.18—0.24％左右。1961
In order to master different varieties of fertilizer in the local soil and climatic conditions, the yield-increasing effect of different crops and its economic and rational application of technology in order to guide the production, we started in 1961 for three consecutive years of domestic fertilizer experimental research. The relevant test data on cotton are summarized below. First, the test method Experimental site located in the upper reaches of the Tarim River north shore of the terraces, the desert poplar soil, the soil texture is sandy, irrigated, water table 2-3 meters, desalination is better, medium fertility, total nitrogen is 0.09-0.11% .The total phosphorus (P_2O_5) is about 0.18-0.24%. 1961
