最近对一些施肥试验的数据进行分析的结果表明,只有合理施肥,才能提高橡胶产量和增加收益。由此,明确对胶树应当有区别地施肥。在这个问题的研究中,根据叶片养分状况、土壤类型和土壤养分状况测定了一些有代表性的胶田或植区的肥料需要,也讨论了根据这些因素施肥的发展。 Recent data from some fertilization experiments show that only reasonable fertilization can increase rubber yields and increase returns. Thus, a clear distinction should be applied to plastic trees fertilization. In this study, the fertilizer needs of some representative fields or plantations were determined according to leaf nutrient status, soil type and soil nutrient status. Development of fertilization based on these factors was also discussed.
