摘　　要：研究园林绿化废弃物堆肥对蔬菜温室大棚土壤温度、棚室温湿度和CO_2浓度的影响。研究表明,在发酵第15~40 d内,堆肥可以提高15 cm覆盖层的土壤温度,维持30 cm覆盖层的土壤温度;可提高棚室内温度,平均提高1℃,最高可提高2.5℃,对湿度影响不大。温度越高堆肥分解越快,释放的CO_2量越大。堆肥发酵产生的热量和释放的CO_2可保护越冬茬蔬菜免遭冻害,使蔬菜安全越冬。The influence of landscaping greening waste compost on soil temperature, air temperature, air humidity and CO2 concentration of greenhouse were studied. The results show that in the fifteenth to fortieth days of fermentation, the composting can effectively improve the soil temperature of the 15 em covering layer and maintain the soil temperature of the 30 cm covering layer, can obviously improve air temperature inside the greenhouse by an average of 1 ℃ and the highest temperature of 2.5 ℃ , and have no influence on the humidity. The higher the temperature is, the faster the decomposition composts, and the greater the amount of CO2 released. Heat and CO2 landscaping greening waste compost fermentation released can effectively protect crop vegetable from cold in winter, improve vegetable immune ability, make vegetable overwintering safely.
