施用新型尿素水稻叶片SPAD值变化特征及产量分析
Dynamic Characteristics of SPAD Value in Rice Leaf and Yield Analysis under the Application of New Urea
摘要
Abstract
The experiment was conducted with 7 treatments,including no nitrogen treatment,normal urea,controlled loss urea,densi-ty network urea, urea containing zine, controlled loss urea one-time fertilization, and normal urea plus zine. The effect of new type urea on dynamic characteristics of SPAD value and yield of rice leaves in Xinyang area was studied by field experiment, aiming to providing scientific basis for large area spreading of new type urea in Xinyang area.The results showed that compared with the normal urea, new type urea could promote alternate phenomenon of the plant leaf of rice, which was helpful for sthenia of rice plant and plumpness of grain.At the tillering stage of rice,new urea could provide nitrogen nutrition of newly-growing leaves,and also guaran-tee nitrogen nutrition of leaves in the lower position.At the booting stage and heading stage,new urea could guarantee nitrogen nutri-tion of grain, and also consideration to nitrogen nutrition of leaves in rice plant. The effect of new urea on increasing production was significantly,compared with the normal urea,increase amplitude of rice yield was urea containing zine 6.23%,normal urea plus zine 5.35%, controlled loss urea 5.13% and density network urea 3.72% respectively. In summary, the effect of urea containing zine and controlled loss urea were better than the other new urea,which has excellent popularizing value in Xinyang area.关键词
