温室或大棚栽培蔬菜因空间闭锁，经常有二氧化碳缺乏现象，在温室或大棚中释放：氧化碳能促进蔬菜早发、早熟、丰产。经试验，辣椒增产19％～64％，黄瓜般增产20%－25%。且增施二氧化碳的来源11有机肥如马粪、秸杆等发酵产生：氧化碳。②套种平菇等食用菌，释放＿氧化碳。③用 Greenhouse or greenhouse cultivation of vegetables due to spatial locking, often lack of carbon dioxide, released in the greenhouse or greenhouse: carbon dioxide can promote early vegetables, early maturity, high yield. After testing, pepper yield 19% to 64%, cucumber-like yield 20% -25%. And increase the source of carbon dioxide 11 Organic fertilizer such as horse manure, straw and other fermented produce: carbon dioxide. ② intercropping mushrooms and other edible mushrooms, the release of carbon monoxide. ③ use
