摘要
该文从蔬菜沙培的基质选择、沙培设施、营养液、蔬菜品种选择和节水等几方面综述了日光温室蔬菜沙培技术研究进展;简要介绍了日光温室蔬菜沙培研究存在的区域性技术发展不平衡、沙培技术要求高、推广环节比较弱、技术完善程度不高等问题;并在此基础上,对蔬菜沙培可以避免根部土传病害的发生,且具有省水、省肥、省工、病虫害少、易获得高产优质的蔬菜产品等优点进行了阐述,并对沙培可有效利用沙荒地、工矿废弃地、盐碱地等非耕地,开拓农民就业途径,增加农民收入,可解决与粮食作物争地矛盾等发展前景进行了展望。
Research progress on vegetable sand culture technology in solar greenhouse were summarized from substrate selection,sand culture facilities, nutrient solution, vegetable variety selection and water saving. The problems existed in solar greenhouse vegetables sand culture of regional technology development imbalance,high technical requirements,the promotion of weak link, low degree of current technology were briefly introduced. And on this basis, the sand culture to avoid the happening of the root soil borne disease,and the advantages including saving water,fertilizer and work,fewer pests,easy to obtain high yield and good quality products,and it could effectively utilize the areas,industrial and mining land and saline-alkali land non-cultivated land, open up ways of rural employment, increase farmers＇ income, resolve conflict with food crops for land etc were prospected.
