用传统的方法栽培大棚蔬菜往往产量低、效益差。实践证明,如改用以下一些新的栽培措施,则可使大棚蔬菜的产量和效益成倍提高。 一、改普通栽培法为覆盖地膜栽培。覆盖地膜利于增温保湿,提早播种,增强抗灾能力,避免肥土流失、减少病虫危害、加快肥料分解,保持土壤疏松结构,促进壮苗早发,获得稳产高产。 The traditional method of growing greenhouse vegetables is often low yield, poor efficiency. Practice has proved that if you switch to some of the following new cultivation measures, you can double the yield and benefits of greenhouse vegetables. First, change the ordinary cultivation method to cover the film cultivation. Covering the plastic film is conducive to warming moisturizing, sowing early and enhance resilience, to avoid soil erosion, reduce pests and diseases, accelerate the decomposition of fertilizers, to maintain loose soil structure, and promote strong seedling early onset, stable and high yield.
