Effect of CO2-concentration to Tomatoes Production under Negative Pressure Pot Irrigation Device

摘要：

　　The test explored the effect of tomatoes with nutrient solution from negative pressure irrigation device by adding carbon dioxide.The results showed that adding carbon dioxide in the moming could increase the height,stem diameter and dry weight of tomato plants,improve SPAD and net photosynthetic rate in tomato leaves,reduce root-shoot ratio,and increase fruit yield and nutrient solution production efficiency.
