一、温度不适宜温度过高或过低均会导致花器官缺陷而引起落花。如番茄在夜温低于15℃,或夜温高于22℃,日温高于35℃会引起大量的落花;辣椒在夜温低于10℃或夜温高于32℃,日温高于38℃或低于16℃时,尽管花芽分化数不少,但所形成的花几乎全部落光,没有结果;茄子在温度高于25℃以上或低于15℃以下时易落花落果。预防措施 1.花期控制适宜的温度条件,防止温度的高限和低限出现。一般应掌握的温度要求是:番茄日温在25～28℃,夜温控制在15～
First, the temperature is not suitable for the temperature is too high or too low will lead to flower organ defects caused by falling flowers. Such as tomato at night temperature below 15 ℃, or night temperature above 22 ℃, day temperature above 35 ℃ will cause a lot of flowers; pepper at night temperature below 10 ℃ or night temperature above 32 ℃, day temperature above At 38 ° C or below, although the number of flower buds was quite small, almost all of the flowers formed were dropped out, with no result. Eggplant easily fell off when the temperature was above 25 ° C or below 15 ° C. Preventive measures 1. Flowering control the appropriate temperature conditions, to prevent the high and low temperature appears. Generally should grasp the temperature requirements are: tomato day temperature at 25 ~ 28 ℃, night temperature control at 15 ~
