Common tomatoes in the greenhouse malformations have multiple ventricular malformations, hollow fruit, cracked fruit, decoction and umbilical decoction and other fruit. The reason, first, excessive use of nitrogen fertilizer at seedling stage, over-nutrition vegetative part of the ground, crown root imbalance; second before and after tomato flower bud differentiation, encountered several days 6 ℃ ~ 8 ℃ low temperature. Respiratory nutrients consumed by the relative reduction in the accumulation of nutrients in the flower, the formation of more carpels, it is easy to form more
