设施栽培环境多数处于密封状态，尤其冬季外界气温低，风口几乎不开，棚内普遍存在二氧化碳亏缺问题，严重制约植物的光合效能。为了解决这一问题，我们对日光温室番茄增施二氧化碳缓释颗粒剂，有效地提高棚内二氧化碳浓度，取得了明显的增产增收效果。试验田设在东港市新城区 Most of the facilities cultivation environment is in a sealed state, especially in winter the outside temperature is low, the tuyere almost does not open, the greenhouse generally has the problem of carbon dioxide deficiency, seriously restricting the photosynthetic efficiency of plants. In order to solve this problem, we added carbon dioxide sustained-release granules to tomato in solar greenhouse, which can effectively increase the concentration of carbon dioxide in the greenhouse and achieved a remarkable increase in yield and income.
