摘　　要：在日光温室条件下进行了番茄自压微水头软管膜下调亏灌溉试验研究,结果表明,开花坐果期以轻度水分胁迫T1(土壤含水率为田间持水量的60%～70%)和结果盛期以轻度水分胁迫T3(土壤含水率为田间持水量的60%～70%)为最优设计。试验说明,复水后有补偿效应、干物质有利于向果实运移与分配,从而促进生殖生长。Under the condition of gravitational flexible hose micro-irrigation, greenhouse tomato regulated deficit irrigation （RDI） experiment was carried out. Results showed that under the condition of deficit irrigation, the light water deficit treatment 1 （soil moisture maintained at 60%-70% of field capacity） and treatment 3 （soil moisture maintained at 60%-70% of field capacity） were the best designs. Compensate effect appeared after deficit irrigation, the dry matter formed in former stage will partly transfer to fruit and distribution to promot tomato growth.
