Abstract: In order to study the effects of different straw fermentations on root zone temperature and CO₂ release of protected vegetable, and tomato growth, five treatments including rice straw (T1), corn straw (T2), tomato straw (T3) and cowpea straw (T4) fermentation in furrow soil as well as control without straw application (CK) of soil-ridged and substrate-embedded cultivation method in Chinese solar greenhouse tomato were designed in winter. The results showed that, compared with CK, four straw application treatments could improve the temperature and CO₂ release of root zone of  solar greenhouse and promote the growth of tomato. The minimum and maximum temperature of root zone in T3 treatment were increased by 2.42 and 2.03  ℃ compared with CK, respectively; the minimum and maximum of CO₂ release were increased by 276 and 387 mg·m^-3, respectively, compared with CK. The growth of tomato was promoted, which was mainly manifested in the increasing of plant height, stem roughness, leaf number and leaf chlorophyll value of tomato. Therefore, the use of tomato straw as furrow landfill material has a better application prospect in solar greenhouse vegetable production.

摘要： 为了研究不同种类秸秆发酵物对设施蔬菜根区温度及CO₂释放的影响，在日光温室内以番茄为供试材料，设置未填埋秸秆（CK）、水稻秸秆（T1）、玉米秸秆（T2）、番茄秸秆（T3）及豇豆秸秆（T4）共5个处理，以垄沟填埋的方式施入土壤，检测冬季土垄内嵌式基质栽培番茄的根区温度、CO₂释放及番茄生长指标变化。结果表明：与CK相比，4个秸秆处理均能不同程度地提高日光温室根区温度和填埋区CO₂释放量，促进番茄生长。其中，番茄秸秆（T3）效果最好，其根区温度的最低值和最高值分别较CK提高了2.42和2.03 ℃，CO₂释放量的最低值和最高值分别较CK提高了276和387 mg·m^-3，并促进了番茄的生长，主要表现在提高了番茄的株高、茎粗、叶片数和叶片叶绿素SPAD值。因此，在日光温室蔬菜生产中，使用以番茄秸秆为主的垄沟填埋物料的方式具有更好的应用前景。
