近几年,蔬菜塑料大棚生产发展迅速,而大棚内土壤的侵蚀也越来越严重。为了指导菜农种好菜,发展生产,我们对大棚内土壤理化性质的变化进行了初步研究。1 材料与方法 1992～1994年,在遂平县关王庙乡大界牌村,对三户村民的塑料大棚内土壤进行了测试。大棚内土壤为潮土,土层深厚,质地偏粘,保水保肥力较强。土壤肥力较高。供试大棚均为1992年秋建棚。以未建棚时所采土作对照,1993年10月9日和1994年
In recent years, the production of vegetable plastic greenhouse has developed rapidly, while the soil erosion in the greenhouse is also more and more serious. In order to guide vegetable farmers to grow good vegetables and develop production, we conducted a preliminary study on the changes of soil physical and chemical properties in greenhouses. Materials and Methods From 1992 to 1994, the soil in the plastic greenhouse of three villagers was tested in Dajiepai Village, Guanwangmiao Township, Suiping County. Soil in the greenhouse Chao soil, deep soil, texture partial sticky, water and fertilizer strong. Soil fertility is higher. For the test sheds were built in autumn 1992 shed. Contrasted with the soil excavated when the shed was not constructed, October 9, 1993 and 1994
