摘要： 为了研究蚯蚓粪对果树根系生长和根际的影响，以“石硖”龙眼为试材，把龙眼的根系剪断后分别插入装有蚯蚓粪、牛粪和果园土的根际袋中，研究断根后龙眼根系的生长情况、根际袋中蚯蚓粪的养分变化情况以及根际微生物的情况。结果表明：与果园土相比，蚯蚓粪和牛粪诱导新根生长的量分别提高了342.3%和231.6%。蚯蚓粪中氮的含量分别比牛粪和果园土高144.3%和434.1%，磷的含量分别高366.5%和1256.0%，钾的含量分别高248.9%和392.0%。蚯蚓粪和牛粪中放线菌的数量分别比果园土高240.5%和211.1%，细菌的数量分别比果园土高255.9%和229.6%，蚯蚓粪中真菌的数量与果园土相差不大，而牛粪中真菌的数量比果园土高204.6%。蚯蚓粪是最适宜龙眼根系生长的基质。

Abstract: To investigate the influences of vermicomposting on growth of cutting root and rhizosphere, the experiment was carried out. Shixia longan was used as tested plants. The cuttin root was put into the rhizosphere bag that was contained vermicompasting, cow dung and orchard soil, respectively. The results showed that: the quantity of fresh roots in vermicompasting and cow dung improved 342.3% and 231.6% compared with the orchard soil, respectively. The content of nitrogen in vermicompasting was higher 144.3% and 434.1% than in cow dung and in orchard soil, respectively. The content of phosphorus in vermicompasting was higher 366.5% and 1256.0% than in cow dung and in orchard soil, respectively. The content of potassium in vermicompasting was higher 248.9% and 392.0% than in cow dung and in orchard soil, respectively. Compared with the orchard soil, the quantity of actinomycete in vermicompasting and cow dung improve 240.5% and 211.1% ,respectively.The quantity of germ improve 255.9% and 229.6%, respectively.The quantity of epiphyte in cow dung improve 204.6% then orchard soil, but vermicompasting and orchard soil was similar. Therefore, vermicompasting was the best matter suitting to groth of root.
