摘要
为了解堆肥施入时期对日光温室内CO2浓度及番茄生育的影响,以新鲜稻草及鸡粪为原料堆制肥料,于不同时期施入日光温室内,测定CO2浓度及番茄生长发育情况。结果表明:堆肥前施处理(定植前30 d施入)较后施处理(定植前1 d施入)能更好的提高温室内CO2浓度及番茄光合和蒸腾速率,促进番茄生长,提高番茄单果重和单株产量,改善果实品质。
Effects of adding compost at different time on CO2 concentration in greenhouse and development of tomato were studied. Its result showed that compared with the after-applying treatment, the preceding-applying composting treatment of straw＋ chicken manure could further more improve the concentration of CO2 in greenhouse and photosynthesis and transpiration, increase the growth and yield of tomato remarkably, and improve the quality of fruit obviously.
