不同灌水方式对辣椒生长、生理的影响
Effects of Different Irrigation Methods on the Growth and Physiology of Hot Pepper
摘要
Abstract
[ Objective I The study aimed to provide scientific basis for water saving irrigation of hot pepper. [ Method ] The effects of normal irrigation, root-zone located irrigation and root-zone alternative irrigation on the growth and physiological indexes were analyzed through potting test. [ Result ] When the lower irrigation limit was 75%θF, the plant height of root-zone located irrigation was significantly lower than that of normal irrigation and root-zone alternative irrigation; compared with normal irrigation, the leaf width of root-zone located irrigation was decreased obviously; the chlorophyll content of normal irrigation was highest, that of root-zone alternative irrigation was secondary and that of root-zone located irrigation was lowest; the proline content of normal irrigation was lowest, that of root-zone alternative irrigation was middle and that of root-zone located irrigation was highest. When the irrigation methods were same, the chlorophyll contents of different lower irrigation limits were shown as: 75% θF >65% θF >55% θF. When the lower irrigation limits were 55% θF and 65% θF, the proline content of rootzone alternative irrigation was significantly higher than that of root-zone located irrigation. When the irrigation methods were same, the leaf width was decreased significantly along with the decreasing of lower irrigation limit. Under the same lower irrigation limit, the leaf width of root-zone alternative irrigation was significantly bigger than that of root-zone located irrigation. [ Conclusion ] Controlling root-zone alternative irrigation was most watersaving and efficient irrigation method.关键词
