摘要
采用再裂区设计,研究稻草施入方式、施入长度及喷施EM三因素对温室土壤CO2释放的综合效应,结果表明各处理均能提高土壤CO2释放速率。随着稻草施入时间的延长,温室土壤CO2释放速率呈逐渐降低趋势。试验筛选出两个较优组合,即A1B3C2和A2B2C2。
By split split plot design, the effect of the applicative way, Length of straw and EM application on the soil respiration released CO_2 in greenhouse was studiged. The results showed that all treatments could increase the soil respiration released rate of CO_2. Along with straw application, the soil respiration released rate of CO2 in greenroom tended to decrease. By experiment, two excellent treatments were xleted, which were A1B3C2 and A2B2C2.
