Temperature is a key factor affecting the growth of flowers. Summer light and high temperatures can easily cause flower burns and affect their growth. To make flowers safe in summer, the following measures should be taken to control the temperature.
Avoiding light and temperature control - In the summer and summer months of July to September, the flowers in the flower garden should be shaded by shade nets, or the pots should be moved to shade, shady or well-ventilated rooms. Ventilation and ventilation to prevent exposure to light and reduce temperature.
Spray water cooling - the temperature is not only affected by light, but also closely related to changes in water. Water has an endothermic function, so you can use water spray to cool down. Dry and water shortage during the high temperature period in summer can easily lead to water shortage in plant cells and cause wilting. In severe cases, it can cause plants to die. Therefore, in the high temperature and dry period, we must strengthen irrigation, timely watering, or spray water on the ground around the plant, wet grass and foliar spray, which can increase the humidity of the soil and air to achieve the effect of lowering the temperature, generally watering In the morning and in the evening.
Hormone thermoregulation: Spraying 750ppm Paclobutrazol, 1500ppm Qingxin, or 1500ppm to 2000ppmBy in the high temperature phase plus 0.1% to 0.2% potassium dihydrogen phosphate inhibits plant growth, accelerates cell maturation, enhances stress tolerance, and relieves stress. High temperature heat damage. Applying aspirin in conjunction with watering can promote stomatal closure and reduce leaf transpiration and avoid high temperature burns.
