人们都已充分认识到土壤和叶片分析对于诊断橡胶树肥料需要的重要意义。苗圃或大田在种植前需要分析代表性土壤的肥力状况,这对于植胶新区特别重要。这种基于最初土壤分析的肥料推荐,将作为头几年苗圃、大田胶树及覆盖作物施肥的指南。一般认为这种土壤分析可作为三年之内苗圃施肥推荐的依据,在大田若植株生长良好,可作为头4年施肥的依据。在第5年和尔后的未开割期,以及刚开割期间,其施肥推荐必须以代表性林地的土壤和叶片分析结果作为依据。
People are well aware of the importance of soil and leaf analysis in diagnosing rubber tree fertilizers. Nursery or field needs to analyze the fertility status of the representative soil before planting, which is particularly important for the new plantation. This fertilizer recommendation, based on the initial soil analysis, will serve as a guide to fertilizing nurseries, field gum trees and cover crops in the first few years. Generally believed that this soil analysis can be used as recommended nursery within three years of fertilization, if the plant grows well in the field can be used as the basis for the first four years of fertilization. During the fifth year and beyond, and during the first cut, the fertilization recommendation must be based on soil and leaf analysis of the representative woodland.
