Summer is the hot season of the year, and hot weather around 35°C often appears. Climate change is not constant. The hot season is an eventful event for potted orchids. The slightest negligence in day-to-day management may create unexpected hazards.
The first is to strengthen ventilation, prevent heatstroke and cool down, high temperature and sultry heat is the enemy of raising blue. Closed-style blue rooms generally have push-pull free-switching aluminum alloy glass windows. As long as there is a temperature difference between indoor and outdoor blue rooms, the degree of opening of the sliding window can be used to control convection and natural ventilation. If the temperature difference is too small and windless, ventilation fans and micro-fans can be used to promote the air circulation. If the temperature exceeds 35°C, water curtains or air conditioners can be used to cool the conditions; if conditions are limited, the ground can often be sprinkled and cooled.
The second is to build humidity according to local conditions, should avoid excessive dry or too wet. In summer, high temperatures, rapid evaporation of water, and low air humidity require efforts to create a suitable environment for the growth of orchids. Sink humidification is generally used to increase air humidity. The sink is preferably set with a blue shelf. Each floor must be equipped with a sink. The lower end of the sink should be provided with a drain switch to facilitate the discharge of sewage from time to time. The depth of the sink is generally 20 cm to 30 cm. It is filled with water and covered with steel wire mesh. The orchid basin sits on top of it, which not only increases the air humidity, but also has a certain cooling effect. In combination with ground water spray, the humidity in daytime can reach 40%, which can basically meet the requirements of orchids for humidity. In case of overcast weather, the humidity in the blue room air is too high. It is necessary to open the ventilation fan, micro fan, etc. in a timely manner so as to promote the air circulation to reduce the air humidity. Watering in summer should be based on pots and planting materials, flexible time and frequency of watering, general watering in the evening and the morning as well, watering generally do not use dipping method and watering method, spray water spray as much as possible to avoid Pour water into the heart of the leaf to cause decay.
The third is to prudently rain, strengthen the blue room, and actively prevent typhoons and storms. Summer is a rainy season. In areas with good air quality, the rainy season may allow orchids to shower, and where there is a lot of air pollution, there is a lot of acid rain, which makes it easy for orchids to cause various diseases and should be resolutely eliminated. In places with good air quality, the most suitable for orchids to rain is a long-lasting gentle and drizzle rain. The rain is fine, Lan Miao is exceptionally spirited and grows rapidly; the growing orchids are most afraid of the "solar rain" and turbulent rain in the hot season. When encountering "Sun Rain," Yilan people should timely infuse orchids with water, so that the heat in the basin should be reduced, and ventilation should be strengthened to dry the water in the heart of the new seedlings as soon as possible. In addition, to strengthen the blue room, pay attention to the weather forecast at any time, once there are extreme weather such as typhoons, they should quickly take measures to provide shelter for the orchids and avoid orchid damage.
Fourth, Qiao Shi fertilizer, promote growth. Summer is the peak season for growing orchids. It is necessary to carry out topdressing, but it is necessary to master the changes according to the temperature. Fertilization is mainly based on topdressing of orchids in early summer. It is appropriate to apply organic fertilizer to the roots, but it is necessary to apply thin fertilizers and fertilization. Fertilization should be carried out in the evening and the next morning should be poured with “returning waterâ€. Can also be top-dressing, inorganic fertilizer can be applied, with one-thousandth of urea plus one-thousandth of potassium dihydrogen phosphate spray. In order to prevent fertilizer damage, the next morning should be sprayed with water to wash the leaves, can also be sprayed with biological bacterial fertilizers, such as root growth, planting, blue king, hi giant, high Tsui and so on. It is best to alternate organic, inorganic and biological fertilizers once a week. After the summer solstice enters the high temperature season, it is forbidden to apply organic or inorganic fertilizers by roots. It is better to fertilize the foliar fertilizers, and one-thousandth of urea can be used to add one-thousandth of potassium dihydrogen phosphate or biological bacterial fertilizer to use alternately. Supplementing nutrients to promote the strong growth of orchid strains.
The fifth is to prevent the mains from cleaning and take precautions against blues. The high-temperature season is also a frequent season of orchid diseases and insect pests. In daily management, the principle of prevention and prevention and control should be combined, and efforts should be made to avoid pests and diseases. Usually pay attention to the cleanliness of the blue room, timely removal of various dirt in the raised blue place, clean the ground and blue frame, often with lime water disinfection. In a high-temperature and high-humidity environment, orchids are prone to breeding scale insects and thrips. These pests can infect blue leaves and should be promptly killed with drugs. Soft rot and stalk rot are the major enemies of orchids in summer. Once they are found, they should be judged and turned immediately. They should not hesitate to cut off the diseased seedlings and adjacent seedlings. They must not be fortunate enough to delay timing.
Organic turmeric extract is derived from the dried rhizomes of turmeric. Turmeric is a ginger plant with a botanical name of Curcuma longa L. The main ingredients of turmeric extract are curcumin. And the curcumin ratio can reach 95% or more. Turmeric has long been used as a natural pigment (E100) in the food industry. It has strong tinting strength, does not fade, but is sensitive to light, heat. Mainly used for dyeing canned foods, sausage products, and sauces.
