百喜草(Paspalum notatum fliigge)、英名Bahia grass,系禾本科雀稗属草本植物。原产拉丁美洲,1963年引入台湾省,经试验认为是一种较好的水土保持草。现广泛用于果园、桑田、茶园的水土保持。在果园做为覆盖作物,其作用不仅是生长过程能保护地面、减轻土壤冲刷,还可刈草作为敷盖(铺盖)材料,减少土壤水分蒸发,减轻旱害,免除中耕除草,节约劳力。而且容易控制,只要在每株果树树冠范围之内铺以10cm厚的覆盖层,百喜草就不会侵入此范围之内与果树争肥争水。种植此草对改良土壤效果十分显著,据台湾试验观测,在果园全园覆盖种植三年,0—20cm深的土层,有机质含量从1.77％提高到2.30％;20—40cm
Paspalum notatum fliigge, the British name Bahia grass, Department of grassgrass Paspalum herb. Originally Latin America, introduced to Taiwan Province in 1963, the experiment that is a better soil and water conservation grass. Is now widely used in orchards, mulberry fields, tea plantations soil and water conservation. In the orchard as a cover crop, its role is not only the growth process can protect the ground, reduce soil erosion, but also mowing as cover (bedding) material to reduce soil moisture evaporation and reduce drought damage, eliminating cultivation and weeding, saving labor. And easy to control, as long as the tree within each tree canopy shop covered with 10cm thick layer, Bahrain will not invade the scope of this dispute with the fruit trees and water. The planting of this grass has very significant effect on soil improvement. According to Taiwan’s experimental observation, the organic matter content is increased from 1.77% to 2.30% in the whole orchard covered with orchards for three years and 0-20cm depth;
