为探索地膜覆盖对果树的影响,从1984年起我们对秦冠、富士苹果和酥梨进行地膜覆盖栽培的多点对比试验。试验表明,地膜覆盖能有效地减缓干寒地区不利自然因素对果树的影响,对提高产量,增强品质,降低成本有明显作用,是行之有效值得推广的新技术。
In order to explore the impact of plastic film mulching on fruit trees, since 1984, we conducted multi-spot comparative experiments on mulching of Qin Guan, Fuji apple and pear. The experiment shows that the plastic film mulching can effectively reduce the impact of adverse natural factors on the fruit trees in dry and cold regions, and has a significant effect on yield enhancement, quality enhancement and cost reduction, which is worthy of promotion.
