Earthwork increases greenhouse CO2
It is well known that carbon dioxide is absorbed by various plants during photosynthesis, and the intensity of photosynthesis increases with the increase of carbon dioxide in the air. Carbon dioxide meets the growing needs of plants. Crops have high yields and good quality. In general, the carbon dioxide content in the atmosphere is 0.03%, while the winter greenhouse greenhouse is in a closed state, and it is far from meeting the demand of cucumbers and tomatoes for carbon dioxide 0.1% to 0.15%. Therefore, it is necessary to artificially supplement carbon dioxide by planting balsam pear, tomatoes and other vegetables in the greenhouse. According to the experiment: cucumbers added carbon dioxide after seedling stage and planting can increase production by 10% to 30% and 20% to 25%, respectively, from the seedling stage of cucumber to persistent carbon dioxide supplementation after planting, and the yield can increase by 31%. After adding carbon dioxide, the melons of cucumbers are straight and the stems are dark green, which greatly increases the yield and disease resistance. Earth-replacement carbon dioxide means that 5 to 6 kilograms of fresh cow dung are piled up per cubic metre of space in the shed. Several points are set in the shed, and the carbon dioxide released after the fermentation of cow dung can satisfy the needs of vegetables.
