幼龄荔枝园种植百喜草改良土壤效果的研究

Research of the Soil Improvement Impact by Planting Paspalum notatum Flugge in the Young Litchi Orchard

当前,许多地区用种草法进行果园的水土保持。本文研究了幼龄荔枝园种植百喜草对土壤的改良作用,结果表明采用全园种植百喜草的模式不仅能够有效地改善土壤通透性,提高土壤微生物数量,增强土壤酶生物活性,而且使土壤理化性状受到改善。但如果种植不当,果树植株与草之间存在着相互争肥的现象,从而对幼龄荔枝植株的生长产生显著影响。

At the moment, grass -planting method has been applied in the orchard for soil conservation. The paper conducted the research on the impact of Paspalum notatum Flugge on improvement of soil in the young Litchi orchard. The result shows that by applying the Paspalum notatum Flugge planting model in the orchard will not only improve effectively the permeability, the microbial amount and the enzyme biological activity of the soil, but also the physicochemical property of the soil. However, if plant improperly, the fruit trees will need contest with the grass for manure, that will have the great influence on the growth of the young litchi plantlet.
