一、深耕细■蔬菜地膜覆盖栽培,根系发育好,在土壤中的分布范围广而深,只有提供深厚的土壤耕作层才有利于根群的发展。然后进行细■,做到畦细碎,没有大坷垃(疙瘩),使畦面平整,不出现坑洼,这样,一方面有利于蔬菜生根、发芽;另一方面也有利于将地膜紧贴在畦土表面,否则,就难于使地膜紧贴在畦土的表面,容易出现地膜破损和膜下杂草丛生。 First, deep plowing ■ vegetable mulching cultivation, root development, distribution in the soil a wide range and deep, only to provide deep soil tillage layer is conducive to the development of the root swarm. And then fine ■, do 畦 fine, no bumpy (pimples), so smooth noodles, no potholes, so that on the one hand conducive to vegetable rooting, germination; the other hand, it will help close the film in the 畦 畦Soil surface, otherwise, it is difficult to make the film close to the soil surface, prone to damage and undergrowth membrane mulching.
