摘要
通过因子分析获得综合指标值,进行模型拟合和优化,提出了延边地区保护地辣椒高产、优质、高效、节水、环保水肥管理体系。当灌水138.9-149.8m^3/(hm^2·次),施纯氮248.3-278.2kg/hm^2,施纯磷140.8-159.7kg/hm^2时兼顾了多项指标要求,实现了保护地辣椒合理施肥和灌水。
By means of factor analysis, comprehensive index is obtained and the model is established and simulated in this paper. Then the water and fertilization management system with high yield, high quality, highly efficiency, water-saving and environmentprotecting for capsicum in protective farmland in Yanbian Region is put forward. The management system , in which the irrigation quota is 138. 9-149.8 m3/hm^2 ,the nitrogenous fertilizer quota is 248. 3-278. 2 kg/hm^2 and the phosphorus fertilizer quota is 140. 8-159.7 kg/hm^2, gives consideration to multiple indexes and realize the reasonable fertilization and irrigation for capsicum in pro teetive farmland.
