How to make cyclamen safer over summer

June is a period of strong growth of Cyclamen, and should be strengthened in the management of high temperature and rain. The northern region should pay attention to cooling and ventilation. In order for the cyclamen to grow smoothly, it must be changed with the increase of bulbs and the increase of leaves and roots in order to meet the needs of growth. All types of cyclamen seedlings will be changed for the third time this month. All the pots are larger than the original ones in order to increase the plant's nutritional area and make the plant more compact. There are two ways to overtake the summer: 1. Continue to cultivate the Cyclamen plants that have more than 10 leaves in the summer and continue to fertilize water while creating a cool environment. After a safe summer, change the pots in early September to cultivate good plants. Large-scale greenhouses generally use evaporative cooling to reduce temperature. That is, a wet and cold wall made of poplar wood, fine shavings or other similar materials is set on three walls around the greenhouse. After soaking with water, the air entering the greenhouse is passed through the wet and cold wall to achieve the purpose of evaporative cooling. . The wet and cold wall is connected with the water tank and the water pump into a circulatory system. The water supply is continuously provided to maintain the humidity. This method is most effective when the outdoor relative humidity is less than 50%, and the effect of evaporative cooling is 80% of the difference between dry and wet temperatures of outdoor air. In addition, forced ventilation, shade cooling, spray cooling, etc. can be used to reduce the greenhouse temperature. As a greenhouse for the long-term cultivation of cyclamen, shade trees should be planted on the south side of the greenhouse to improve the greenhouse environmental conditions. As the continued summer cyclamen continued to grow in July and August, the new leaves continued to unfold, and there were buds or cultivars. 2. Make the plants dormant After the flowering period of cyclamen is over, stop the watering to make the basin soil dry, the leaves completely fall off, and then remove the dead leaves and put it in a shaded and ventilated place where the direct sunlight is not direct and the rain does not reach. Bulbs rot and create conditions suitable for dormancy to make it safer over the summer. Transplanting will be carried out in early September. This is a relatively easy and trouble-free method of overriding. Regardless of the method used, care should be taken to prevent bulb rot in the summer months when it is hot and rainy, so as to ensure safe summers. The success of Cyclamen over summer depends on the high temperature period in July and August. In case of rainy days after entering the rainy season in summer, special attention should be paid to the bulbs not being exposed to rain. Plastic sheets may be used to cover the rain. At the same time, pest and disease control must be strengthened, and Bordeaux mixture can be sprayed.
