Differences in types of row cover can affect the microclimate under the row cover. The temperature at the soil surface and the air temperature between the row cover and soil depend on the physical characteristics of film mulch. Plant growth was more closely related to the accumulated effective soil temperature at a depth of 2.5cm than the accumulated effective temperature between the soil surface and row cover. The method of estimating the heat balance at the row cover is presented. Fairly reasonable agreement was obtained between the simulation experimental results and observations, and this helps to explain the characteristics of heat fluxes in the row cover.
