日光温室蔬菜连作,造成土壤养分积累和养分失衡,导致蔬菜产量低、品质差、生理病害严重。要解决日光温室蔬菜连作问题,必须做到设施蔬菜土壤的科学施肥及在棚室应用地膜覆盖高垄栽培方法以及科学防治病虫害。由于土壤连年集约化生产,大量施用化肥,加之大棚覆盖土壤得不到充分的降雨淋洗,造成土壤盐分积累和养分失衡,导致蔬菜产量低、品质差,生理病害严重。要解决这一问题,必须采取科学施肥及栽培管理措施。
Solar greenhouse vegetable continuous cropping, resulting in the accumulation of soil nutrients and nutrient imbalance, resulting in low vegetable yield, poor quality, severe physiological diseases. To solve the problem of continuous cropping of vegetables in solar greenhouse, we must accomplish the scientific fertilization of vegetable soils and the application of plastic film mulching and high ridge cultivation methods in the greenhouse to prevent and control pests and diseases. Due to intensive production of soil in successive years, large-scale application of chemical fertilizers and insufficient coverage of soil by rainfall in the greenhouses resulted in accumulation of soil salinity and nutrient imbalance, resulting in low yield of vegetables, poor quality and serious physiological diseases. To solve this problem, we must adopt scientific fertilization and cultivation management measures.
