不同灌溉量下微水溶性缓释肥料在春玉米的肥效及环境效应研究
STUDY OF SLIGHTLY-WATER-SOLUBLE SLOW-RELEASE FERTILIZER ON SPRING CORN AND ENVIRONMENT EFFECT UNDER THE CONDITION OF DIFFERENT IRRIGATION AMOUNT
摘要
Abstract
A field experiment was conducted to study the fertilizer and its environment effect on spring corn under the condition of different irrigation amount with a kind of slightly-water-soluble slow-release fertilizer which is suitable for semi-arid climate conditions(Beijing Academy of agriculture and forestry sciences development,called W,similarly hereinafter) with four different treatments of conventional irrigation without fertilization treatment(CK),the conventional irrigation urea treatment(N),the conventional irrigation with slightly-water-soluble slow-release fertilizer treatment(W1),reducing irrigation amount with slightly-water-soluble slow-release fertilizer treatment(W2).Results showed that,compared with CK treatment,W1 treatment significantly increased plant height,then W2 treatment significantly increased the total N content of plant and grain and yield of spring corn,but chlorophyll,plant height was not significantly improved,and N treatment significantly increased the grain total N content only(p 0.05).Compared with N,W1 treatment significantly increased the plant height,fertilizer P and K efficiency and yield of spring corn(p 0.05),and the highest value of NO3—N content appeared in 80cm-depth soil,and leaching amount significantly reduced(p 0.05),and W2 treatment significantly increased the total N content of plant and grain,fertilizer nitrogen,phosphorus,potassium use efficiency and yield,and the highest value of NO3—N content appeared in 60cm-depth soil,and leaching amount significantly reduced(p 0.05).Therefore,the slightly-water-soluble slow-release fertilizer could improve yield,save water irrigation and reduce NO3—N content leaching.关键词
