Beneficial Effects of Crop Residues and Manure Mizture Compost in Greenhouse on Vegetable Production and Environment Protection
In the present study, a new strategy based on the use of crop residues and manure mixture (CRMM) compost was developed to elevate greenhouse CO2 concentrations. During the whole cultivation period, the CO2 concentrations in the CRMM composting treated greenhouses increased by more than 100% of that in the control greenhouses. It can also slightly increase temperature in the greenhouse during the morning and evening thereby aiding the prevention of cold injury to plants. Consequently, vegetable production was more than doubled in the greenhouse for all vegetable species grown. In addition to these benefits, if the technology was popularized in China the manure discharged to water bodies could be decreased by 14-54% thereby improving environmental quality. In conclusion, the use of CRMM compost in greenhouses not only increase farmer income through increase vegetable production, but also alleviates environment pollution efficiently and economically.
