温室番茄在栽培过程中极易出现畸形果,如尖顶果、桃形果和指形果等,使番茄商品价值降低。原因:①花芽分化和发育时遇到连续5～6℃或3～4℃的低夜温,易产生畸形果,冬春茬西红柿1～2穗果易畸形多是此原因造成;②苗龄拉长,低温或干旱持续时间长,幼苗处在抑制生长条件下,花器易木栓 Greenhouse tomatoes are prone to deformities in the cultivation process, such as spire fruit, peach fruit and finger fruit, so that the value of tomato products to reduce. The reason: 1, flower bud differentiation and development encountered continuous 5 ~ 6 ℃ or 3 ~ 4 ℃ low night temperature, easy to produce deformity fruit, winter and spring tomatoes 1 to 2 more susceptible to deformity caused by this reason; ② seedling age Elongated, cold or prolonged drought duration, seedling growth inhibition in the environment, easy to plug the flowers
