我们自1980—1981年对塑料大棚采取高垄进行地面覆盖,对土壤温度、空气湿度、光照和二氧化碳浓度等方面按节气进行测试,试图探索覆盖后小气候变化情况,为进一步合理利用地面覆盖这项农业措施提供依据。
Since 1980-1981, we have taken high ridge coverings for plastic greenhouses and tested solar climates in terms of soil temperature, air humidity, light and carbon dioxide concentration in an attempt to explore the microclimate changes after the cover so as to further rationalize the use of the ground cover Provide the basis for agricultural measures.
