地膜覆盖栽培技术能有效地调节、控制、改善田间温、光、水、气、营养等环境因子,为农作物生长创造良好条件。无论山区、丘陵,还是经济、粮食作物都可因地制宜采用,增产幅度大,经济效益高。但是,如何降低地膜覆盖栽培的成本,是提高地膜栽培的经济效益,进一步扩大推广面积,加快推广速度的一个重要问题。目前,有的农民对地膜栽培的顾虑较大,主要原因是覆盖成本较高,怕增产不增收。因此,降低地膜栽培成本,必将加快地膜栽培的进一步发展。那么,怎样才能降低地膜栽培的成本呢?其对策主要有以下几点: 一、根据不同用途,选用不同品种、规格和质量的地膜。关于塑料薄膜的规格质量问题,根 Film mulching cultivation techniques can effectively regulate, control and improve environmental factors such as temperature, light, water, gas and nutrition in the field, and create favorable conditions for crop growth. Regardless of the mountains, hills, or economy, food crops can be adapted to local conditions, increase yield, high economic efficiency. However, how to reduce the cost of mulching cultivation is an important issue to improve the economic benefits of mulching cultivation, further expand the area of ​​popularization and speed up popularization. At present, some farmers are more concerned about the cultivation of plastic mulch, mainly due to the higher cost of covering and being afraid of increasing production without increasing income. Therefore, to reduce the cost of film cultivation, will speed up the further development of film cultivation. So, how to reduce the cost of film cultivation? The countermeasures are the following: First, according to different uses, use different varieties, specifications and quality of the film. Plastic film specifications on the quality problems, roots
