温室芹菜在生长过程中如果遇到土壤湿度过大,室内温度过高,则会出现菜梗腐烂现象。一开始,幼嫩菜梗上出现水渍状病斑,然后整个菜梗象开水烫过一样。逐渐全部烂掉,若不及时采取措施,会造成大面积死亡。预防温室芹菜烂梗方法如下: 一、中耕。发现菜梗有病斑时,应马上停止浇水,及时中耕散墒,降低土壤湿度和温度。 二、及时放风,控制室温。温室内适宜温度白天为20—22℃,晚上为13～18℃。若超过此温就应及时放风降温。若室内温度过高,烂梗会逐渐加重。因此,在晴朗无风天,应多放风,以增强芹菜抗病力。
Greenhouse celery in the growth process if you encounter soil humidity is too high, the indoor temperature is too high, there will be rotten vegetables dish stems. At first, the watermelon-like lesion appears on the young bellflower, and then the whole cauliflower resembles boiling water. Gradually all rotted, if not promptly taken measures, will result in large-scale death. Celery stem rot prevention methods are as follows: First, cultivating. Found that when the pedicel lesions, should immediately stop watering, timely cultivation of soil moisture, reduce soil moisture and temperature. Second, timely ventilation, control room temperature. Greenhouse suitable temperature daytime 20-22 ℃, 13 ~ 18 ℃ at night. If more than this temperature should be timely ventilation cool. If the indoor temperature is too high, the bad terrier will gradually increase. Therefore, in a sunny day, should be more wind to enhance celery resistance.
