本文对1975～1986年有关果树地膜覆盖的系列研究资料进行了总结分析。认为在干旱地区,地膜覆盖是果树发展和增产的重要措施之一。覆盖具有温室、蓄水保墒、免耕、增肥和增光等多种生理生态效应,从而产生提高幼树成活率、加速生长、促进成花、提早结果,提高座果率、增加产量和提高果实品质等显著作用。还具有节约用水、用电、用工、用肥和病虫防费用等显著经济效果。最后还将地膜覆盖的技术细节作了进一步说明。
This paper summarizes a series of research data about the mulching of fruit trees from 1975 to 1986. It is considered that mulching is one of the important measures for the development and yield increase of fruit trees in arid areas. Covering a variety of physiological and ecological effects such as greenhouse, water and soil conservation, no tillage, fertilization and light enhancement, etc., thereby resulting in raising the survival rate of saplings, accelerating growth, promoting flowering, early result, increasing fruit set rate, increasing yield and improving fruit Quality and other significant role. Also has significant economic benefits such as water conservation, electricity, labor, fertilizer and pest and disease prevention costs. Finally, the technical details of the mulch cover were further explained.
