山丘地区是果品的主要产地,为果树生产提供了丰富的土地和光热资源。但因其干旱瘠薄,水肥保证差则成为果树增产的主要限制因素。为此,探求山丘果园旱栽保水培肥及其增产优质综合配套技术,在目前我国果树生产中占有重要的地位。相继推广应用的果园覆膜和穴贮肥水地膜覆盖技术,在旱地果树栽培中起到了巨大作用。鉴于当前山丘果园普遍存在有机质少、缺水,又习惯于常年保持园内无草的清耕休闲制,从立足于 Hill area is the main producing area of ​​fruit, which provides rich land and light and heat resources for fruit tree production. However, due to its arid infertility, poor water and fertilizer guarantee has become the main limiting factor for the increase of fruit trees. To this end, to explore hill orchard dry planting water and fertilizer and its production of high-yielding comprehensive supporting technology, fruit production in our country occupies an important position. Successively promote the use of orchard mulching and storage of fertilizer water film mulching techniques, fruit cultivation in dry land played a huge role. In view of the current hill orchard ubiquitous organic matter, water shortage, but also accustomed to perennial to maintain grass-free garden clearing farming system, based on the
