一、特性西红柿生长喜温喜阳光,但又怕高温酷暑,在光照不足条件下与徒长、病多、果小,低温和高温条件下都不易坐果,生长停滞甚至死亡。其营养生长期的适宜温度;苗期花芽分化15℃~25℃,开花结果期20℃~28℃,昼夜温差5℃~10℃有利于生长发育。因此,根据西红柿生长环境特点,西红柿优质高产需要以下方面管理,并在早期做好病虫害预防工作。二、选择
First, the characteristics of tomato growth hi warm hi sunshine, but afraid of high temperature and heat, under the conditions of insufficient lighting with leggy, sick, fruit small, low temperature and high temperature are not easy to sit, growth stagnation or even death. The optimum temperature for vegetative growth is 15 ℃ ~ 25 ℃ in flower bud stage, 20 ℃ ~ 28 ℃ in flowering stage and 5 ℃ ~ 10 ℃ in daytime and nighttime, which is good for growth and development. Therefore, according to the characteristics of the growth environment of tomatoes, tomato high-quality and high-yield needs the following aspects of management, and early prevention of pests and diseases do a good job. Second, choose
