本文旨在介绍目前国内尚未实用化,但确有经济实效、完全适合在我国研究推广的新技术。一、浮膜覆盖浮膜覆盖是近几年发展起来的一种新的覆盖栽培技术。它利用通气材料如无纺布,直接或留有间隔地覆盖作物(首推蔬菜),不仅具备地膜覆盖对土壤保温保湿的特点,而且能防止或减轻冷害、霜害、风害、鸟虫害,促进作物生长发育,使作物早熟丰产。与地膜相比,浮膜可多次使用,不污染土壤,使用方法灵活多样。因
The purpose of this paper is to introduce the new technology which is not yet practical in China but does have economic effect and is totally suitable for research and popularization in China. First, the floating membrane cover Floating membrane cover is developed in recent years, a new cover cultivation techniques. It uses aerated material such as non-woven fabric, covering the crops directly or with intervals (top-grade vegetables), not only has the characteristics of plastic film mulching and soil moisture retention, but also can prevent or reduce chilling damage, frost damage, wind damage, bird pests and diseases Crop growth and development, crop early yield. Compared with the film, the film can be used repeatedly, does not contaminate the soil, the use of flexible methods. because
