果园覆草,是果园科学管理的一项重大改革。美国、日本、欧洲等国家早已普及,我国山东省在1987年开始推广果园覆草并取得可喜成果。果品质量的优劣和单产的高低,除了品种本身外,树体的营养状况是很重要的制约因素。内蒙地区果园面积已达50多万亩,但大部分果园立地条件差,土壤瘠薄,肥料不足。加之干旱,降水量少,不仅果品质量差,单产也很低。采用果园覆草,将使果园地面常年保持15～20厘米的草被,以起到增肥、蓄水、灭草、免耕、防冻和改善土壤中水、肥、气,热条件,为果园土壤中的动物和微生物创造一个良好的环境,有利于土壤营养物质的积累,
Orchard mulching, orchard scientific management is a major reform. The United States, Japan, Europe and other countries have long been popular, Shandong Province, China started in 1987 to promote grass orchard grass and achieved gratifying results. The quality of fruit and the level of yield, in addition to the variety itself, the tree’s nutritional status is a very important constraint. Inner Mongolia orchard area has reached more than 500000 acres, but most of the orchard poor site conditions, soil infertility, inadequate fertilizer. Coupled with the drought, less precipitation, not only the poor quality of fruit, yield is also very low. The use of orchard mulching will keep perennial orchard ground 15 to 20 cm of grass, in order to play a fertilizer, water, weeds, no tillage, frost and improve the soil water, fertilizer, gas and heat conditions for the orchard Soil animals and microorganisms to create a good environment conducive to the accumulation of soil nutrients,
