在加工番茄生育期内利用膜下滴灌技术随水滴施 CO2 水溶液，研究其对加工番茄生长发育的影响。试验通过随水滴施 CO2 水溶液与常规灌溉作对比，分析试验数据得出:在加工番茄生育期内随水滴施 CO2 水溶液对它的农艺性状影响比常规灌溉的大，加工番茄的株高、叶绿素含量、花数、单株红果个数、土壤电导率(EC)、理论产量及实际产量等指标明显好于常规灌溉，且生育期较常规灌溉提前 2 d。由此可见，随水滴施CO2水溶液有利于加工番茄的生长发育并提高产量，具有良好的市场推广前景。
Effects of drip irrigation with CO2 aqueous solution on agronomic traits and yield of processing tomato
The effect of drip irrigation under film on the growth and development of processing tomato was studied by drip irrigation with CO2 aqueous solution during the growth period of processing tomato.The experiment was compared with conventional irrigation by drip irrigation with CO2 aqueous solution.The results showed that the effect of drip irrigation with CO2 aqueous solution on the agronomic traits of processing tomato was greater than that of conventional irrigation during the growth period of processing tomato.The plant height,chlorophyll content,flower number,number of red fruits per plant,soil conductivity,theoretical and actual yield of processing tomato were significantly better than those of conventional irrigation,and the growth period was 2 days earlier than that of conventional irrigation.It can be seen that the application of CO2 aqueous solution with water droplets is beneficial to the growth and development of processing tomatoes and the increase of yield,with good market promotion prospects.
