Early Autumn Orchid

Autumn is coming. Most of the six provinces and one city in eastern China are still shrouded in high temperatures, and the really cool autumn will have to wait for about January before the wind clears the moon. Climate Yilan. For this reason, this period of time is still a busy time for the Lan people. A little carelessness will cause losses; as long as it is carefully managed, Lan Hui can reap a bumper harvest. The prevention of autumn tigers is the top priority. At the beginning of this autumn, the temperature is still high. The high temperature of 35 mi 38 degrees is raging everywhere. It is really unbearably hot. Lan Hui grew up in the high mountains with a cool breeze; when she came to our orchid room, she was steaming and stuffy. Ventilation and cooling will be inviolable. The fan is bound to keep running normally during the day. If conditional Lanyou, air conditioning at noon time. With the water curtain open, Lan Hui must be very comfortable. Man-made climate is the key to conquering autumn tigers. Increase humidity to prevent dryness. The lack of rain in early autumn and the low humidity in the air will seriously affect the normal growth of Lanhui. Water can be used. Spraying, watering the ground and other methods of humidification. But it should be noted that after being drenched in water, it must be dried with a micro-fan. Or soft rot. Service diseases and other bacterial diseases will follow, so that the growing Lan Hui will suffer, then the loss outweighs the gain. The basin should be properly watered more than usual, because the water in the basin in autumn is dry from the bottom up, and once the basin is dry, Lanhui will be affected. If it is light, it will be scorched, and if it is heavy, it will be stiff. Never take it lightly. It is very necessary to do a good job in defense. There are many coastal cities in East China, and early autumn is a typhoon. The dangerous period of a tropical storm, if careless, will make Lan Hui likely to cause disaster. Therefore, we should pay close attention to the weather forecast and prepare for it in advance. The blue shed should be strengthened, the blue frame should be stable, the doors and windows should be flexible, and the shade net can be put in and out freely. In this way, when a typhoon comes, we can stay in low gear anytime and anywhere. Temperature difference between morning and evening, proper fertilization. After a summer, Lan Hui is about to enter the next golden growth period. There is little fertilizer left in the basin and there is an urgent need to replenish nutrients. We can make use of the relatively low temperature in the morning and evening to properly irrigate some thin organic fertilizer. Usually spray a little inorganic fertilizer every now and then. Be sure to pay attention to the return water after fertilization. To make the new seedlings strong and the buds beautiful. At this time, fertilization should be based on phosphorus and potassium fertilizer, and a small amount of nitrogen fertilizer. It will do no harm to Lan Hui. We must persist in preventing diseases and insect pests. Because of the high temperature in early autumn, diseases and insect pests are still rampant. Only by giving priority to prevention can we stabilize the growth of Lanhui. Some compound drugs such as stone-sulfur mixture, carbendazim and potassium thiophanate can be used for sterilization. Insect control drugs can use some permethrin drugs, which is more environmentally friendly. According to the strength and weakness of Lanhui, divide and guard against it. Consider the temperature. Seedling quality factor, slightly lighter when used. It is not only effective, but also needs to prevent the occurrence of drug damage. When you can't determine the amount of medicine, you can use several pots of different doses of flowers to test it first, in order to be foolproof. Basic preparation, do in front. Consider the Autumn Equinox season to start to change the basin, put the basin in advance. Plant materials and other purchased, immersed in water disinfection. When the air is crisp in autumn, you can safely count the results of raising orchids over the past year and sum up experiences and lessons. That's the fun of raising orchids.
