| 摘 要： | 根据数年来的观测表明,在生产实践中出现有少量的植株(称其为"超高产橡胶芽接树"),其单株产胶量约达当地普通橡胶芽接树平均单株产胶量的15～20倍.为了探索这些超高产橡胶芽接树高产的原因,笔者对其(砧木为无选择种子砧木,接穗为PB86)根际及立地环境土壤的养分状况,pH值,交换性钙、镁含量,以及土壤酶活性等进行研究.结果表明,超高产橡胶芽接树单株的根际土壤微生态环境(尤其是有机质、速效N含量和土壤酶活性)优于对照株,但其立地环境土壤微生态环境并不优于对照株.

| Abstract: | There are some individual rubber budding trees yielding especially high in rubber plantations.In order to find some evidences for special high yield of these individual rubber budding trees,the conditions of some high-yielding rubber budding trees(PB86) such as nutrient status,pH,exchangeable performance and soil enzyme activities of rhizosphere are discussed.The results showed that the micro-ecological conditions around the rhizosphere soil of the very high yielding trees were better than those of the cont... |
