Abstract
The effect of drip irrigation and drip irrigation under mulch on stem diameter,height,above-ground and under-ground root biomass of tomato plants and tomato yield were studied.The results showed that compared with drip irrigation treatment,the plant stem diameter was obvious increased by the treatment of drip irrigation under mulch,the stem diameter by the treatment of drip irrigation under mulch in each other stages was significantly higher than that by drip irrigation treatment.The film mulching had obvious promotion on above-ground and under-ground root biomass accumulation of tomato under drip irrigation and promote the increment of tomato yield.The research provided the practical reference for developing drip irrigation technology of water saving in protected field of northeast area.
