我国的果树多种植在丘陵山地,土壤瘠薄、蓄水保墒能力低,这些因素在很大程度上制约着果树增产。因此,探求山地果园的节水管理措施,缓解水肥资源的供需矛盾,对于促进果树生产的发展具有重要意义。近年来,北方(以山东为主)正大力推广果园覆草,获得了较好的综合效益,南方各地果园也竞相效尤。本文就果园覆草对土壤及果树的效应及问题作综述和讨论。 Many fruit trees in our country are planted in the hilly and mountainous regions, soils are infertile, and their ability to store water and soil moisture is low. These factors restrict the increase of fruit trees to a great extent. Therefore, to explore the mountain water conservancy management measures to alleviate the contradiction between supply and demand of water and fertilizer resources, for promoting the development of fruit tree production is of great significance. In recent years, the north (mainly Shandong) is vigorously promoting orchard mulching grass, access to a better overall efficiency, the orchards around the South are also competing effect. This paper reviews or discusses the effects of mulching orchard on soil and fruit trees.
