一、试验目的:随着农业科技的发展,应用于农业生产中的各种微肥日益增多,为验证各种微肥在棉花生产中的增产效果,比较筛选出在我县土壤肥力,自然条件和栽培条件下投资少,收益大的微肥品种,今年我站根据县粮棉生产指挥部的安排,在棉花上进行喷施微肥对比小区试验,现将试验结果总结如下:二、试验方案:1.试验布置:试验地点在农技中心试验地,前茬为棉花,秋翻春灌地.播前取土化验分析,土壤中有机质11.605g/kg,全N0.642g/kg,碱解N85.581mg/kg;全P0.559g/kg,速效P9.675mg/kg.2.供试品种:棉花军棉一号品种.3.处理设计:设9个处理A.“天骄”牌高效液肥150g/亩.B、“田老茂”微肥100g/亩.C.磷酸二氢钾150g/亩.D.喷施宝5ml/亩.E.硫酸锌50g/亩.F.增产菌10g/亩.G.硼砂50g/亩.H.肥宝100g/亩.
First, the purpose of the experiment: With the development of agricultural science and technology, increasing application of various kinds of micro-fertilizer in agricultural production, in order to verify the effect of various kinds of micro-fertilizer in cotton production increased, compared to select the soil fertility in my county, natural conditions And cultivation conditions, less investment, large benefit fertilizer varieties, this station I station grain and cotton production headquarters in accordance with the arrangements for the cotton on the spraying of fertilizer compared to the plot test, the test results are summarized as follows: Second, the test program : 1. Test arrangement: The experimental site was in the experiment center of agricultural technology center, the former crop was cotton and the autumn was spring irrigation.The analysis of soil taking soil before sowing was 11.605g / kg, N0.642g / kg, N85 .581mg / kg; whole P0.559g / kg, quick-acting P9.675mg / kg.2 Test varieties: cotton Junmian 1 varieties .3 treatment design: set 9 treatment A. “Tianjiao” brand high-efficient liquid fertilizer 150g / Mu.
