南京地区春季气候多变,夏菜生产很不稳定,采用各种覆盖措施十分必要.为深入探讨不同覆盖形式下土壤及近地气层的小气候效应,选择夏菜适宜覆盖形式,进行了本试验.材料与方法在马群公社石坝三队设立13亩不同覆盖形式的辣椒田.品种为南京早椒×上海甜椒.覆盖形式有小棚加地膜(棚高80厘米,跨度135厘米)、小棚(无地膜)、地膜,以露地为对照.小棚选用透明的聚乙烯薄膜,厚度约0.1
In spring and autumn in Nanjing, the spring climate is changeable, the production of summer vegetables is unstable, so it is necessary to adopt various covering measures.In order to study the microclimate effects of soils and the near-surface gas layers under different coverage forms, Materials and Methods The 13-mu pepper field with different coverage forms was set up in the Shiba 3 Corps of the Hunchun commune, with the cultivars being Nanjing Zaojiao × Shanghai Bell Pepper, covering the form of shed and mulch (80 cm in height and 135 cm in span) Shed (no mulching), mulching, with open field as a control. Shed selection of transparent polyethylene film thickness of about 0.1
