摘要
陈同斌,项月琴:盐化潮土中硫酸钾对夏玉米产量及氮钾交互作用的影响,《生态农业研究》,3(4)1995;44—48 通过田间试验探讨了轻度盐渍化潮土中施用硫酸钾对夏玉米干物质产量及氮钾养分吸收和再利用的影响。在速效钾含量较高的供试土壤中,施钾对高产夏玉米具有明显的增产效果和促进植物对氮钾的吸收,但明显降低了生长后期植物体中钾和氮的再循环率。
Chen Tongbin and Xiang Yueqin (Institute of Geography,CAS,Beijing 100101): The influences of potassium sulfate on maize yield and interaction of nitrogen and potassium, EAR, 3(4)1995:44-48Field experiment was carried out to study the effects of K2SO4 application on maize yield, biomass, N and K uptake and their re-use in slightly salinized Chao soil. The results showed that for the tested soil with high available K content,K supply greatly increased the output of summer corn and improved N and K uptake by the plants ,but reduced the recycling rate of N and K in the plants significantly at the later growth stage.
