地膜覆盖栽培因其显著的优点,为农业生产做出了巨大的贡献。但是,覆膜栽培也有不足的一面,例如马铃薯、西红柿等作物采用覆膜栽培,容易出现早衰或生长失调等问题,致使这些作物达不到预期的增产效果。近年来,在生产上开始初步应用的有孔地膜在很大程度上克服了普通地膜的不足。这种地膜只是在普通
Mulch mulch cultivation has made tremendous contributions to agricultural production due to its significant advantages. However, there is also a downside of film cultivation. For example, crop cultivation of potatoes, tomatoes and the like is prone to problems such as premature aging or poor growth, resulting in the failure of these crops to achieve the expected increase in yield. In recent years, the initial application in the production of perforated film to a large extent to overcome the lack of ordinary film. This film is only ordinary
