摘要
在泰米尔纳德邦农业大学进行了2019年和2020年秋收期间不同自动滴灌方式对沙质粘土壤土番茄作物的田间试验。测试了4种不同自动滴灌系统的5种处理，分别是基于时间的滴灌、基于体积的滴灌、基于土壤湿度传感器的滴灌、基于开关张力计的滴灌和一种传统的滴灌方法。结果表明，基于张力计的滴灌方法的果实产量分别为95.11和96.21 t ha-1，水分利用效率分别为21.10和25.42 t ha-mm-1，比常规灌溉方法增产。在上述处理之后，番茄进行土壤水分传感器滴灌处理。在2019年和2020年的kharif期间，与传统灌溉方法相比，基于张力计的滴灌有助于节水54.91%和60.55%。
Effect of Automated Drip Irrigation System on Yield and Water Use Efficiency of Tomato (Solanum lycopersicum L.)
Field experiment was conducted to evaluate the performance of different automated drip irrigation on tomato crop under sandy clay loam soil in Tamil Nadu Agricultural University during kharif 2019 and kharif 2020. Five treatments comprising 4 different automated drip irrigation systems are time based drip irrigation, volume based drip irrigation, soil moisture sensor based irrigation, switching tensiometer based irrigation and one is conventional method of irrigation were tested. The results revealed that tensiometer based drip irrigation recorded higher fruit yield of 95.11 and 96.21 t ha-1 and water use efficiency of 21.10 and 25.42 t ha-mm-1 resulting in increment over conventional method of irrigation. However, the above treatment was followed by soil moisture sensor based drip irrigation in tomato. Tensiometer based drip irrigation helps to save the water up to 54.91 and 60.55 % compared to conventional method of irrigation during kharif 2019 and 2020.
