茄子为一年生草本植物,保护地栽培的茄子根系主要分布在0-30厘米的耕层内。茄子根系的再生能力较差,木质比较早,不宜多次移植。茄子对温度要求比较严格,17℃以下生长缓慢,10℃以下引起生理代谢失调,15℃以下落花。花芽分化的适宜温度白天为20℃-25℃,夜间为15℃-20℃,温度偏低时,花 Eggplant is an annual herb, the protection of cultivated eggplant roots are mainly distributed in 0-30 cm of tillage. Eggplant root regeneration is poor, relatively early wood, should not be transplanted. Eggplant temperature is more stringent requirements, slow growth below 17 ℃, 10 ℃ caused by physiological and metabolic disorders below 15 ℃. The suitable temperature for flower bud differentiation is 20 ℃ -25 ℃ in the daytime and 15 ℃ -20 ℃ in the nighttime. When the temperature is low,
