摘　　要：研究了5种大棚保护地栽培方式的气温、土温变化,及其对蘘荷、白扁豆和毛豆的促早效应,并比较了各处理的投入、产出等,结果表明:不同覆盖处理间的最高气温差异较小,而最低气温差异较大,5、10、20 cm的3个土壤温度均有较大差异,可见各处理均能有效提高大棚的土温和气温;在大棚双层塑膜覆盖+土壤间隔填埋秸秆处理集成小拱棚覆盖方式下,其增温效应和经济效益最佳。The paper studied the changes in air temperature and soil temperature of five cultivation modes in the protected fields of greenhouse as well as their early - maturing effect upon Zingiber mioga, white haricot bean and green soybean, and compared the input and output of each treatment. The results showed that there was relatively small difference in the maximum air temperature, and relatively large difference in the minimum air temperature among different mulching treatments. Soil temperatures at the soil depth of 5 cm, 10 cm and 20 cm were quite different. Each treatment could effectively enhance the soil temperature and air temperature in greenhouse. Greenhouse double - plastic mulching plus burying straw into the soil at intervals and low - arch - shed mulching could obtain the best temperatureincreasing effect and economic benefits.
