1.结果前的管理 从定植到第一穗果膨大,管理的重点是提高棚内的气温和地温,防寒防冻,加速缓苗。定植后3～5天内,尽量不放风,白天棚温维持在25～30℃,夜间13～15℃。不盖地膜的,要多中耕松土,提高地温,促进发根缓苗。缓苗后开始逐渐通风换气,降温降湿,白天保持棚温20～25℃,夜间保持13～15℃。 大棚春番茄定植10天左右,第一花序就开始开花。为使开花坐果整齐,减少落花落果,要控制浇水,进行
1. The results of the management before the first from the colonization inflated management focus is to raise the temperature and ground shed temperature, antifreeze cold, accelerate Huanmiao. 3 to 5 days after planting, try not to let the wind, during the day shed temperature was maintained at 25 ~ 30 ℃, night 13 ~ 15 ℃. Do not cover the film, to cultivate more soil, improve ground temperature, promote hair root Huanmiao. After Huanmiao began gradually ventilation, cooling and humidity, shed temperature during the day to maintain 20 ~ 25 ℃, night to maintain 13 ~ 15 ℃. Greenhouse tomato planting about 10 days, the first inflorescence began to flowering. In order to flowering fruit tidy, reducing the drop of fruit, to control the watering
