晋西山地果园多为旱作果园,很少有灌溉条件,干旱缺水是发展果树生产的一个制约因素,因而果园土壤保水技术对当地果树生产具有重要作用。一些资料表明,应用地膜及其它覆盖材料覆盖树盘有利于果树的生长发育;化工产品高吸水树脂作为土壤保水剂已开始在多种作物栽培中试用,但目前很少见到在旱地果园中的应用报道,为了筛选 Most of the mountainous orchards in Shanxi Province are mostly orchards, with few irrigation conditions. Arid and water deficit is a limiting factor in the development of fruit trees. Therefore, soil water conservation techniques in orchards play an important role in the production of local fruit trees. Some data indicate that the application of plastic film and other covering materials to cover the tree plate is conducive to the growth and development of fruit trees; chemical superabsorbent resin as a soil water-retaining agent has begun to test a variety of crop cultivation, but rarely seen in dry land orchards Application reports, for screening
