The summer is hot

This year's mildew rainy season varies greatly due to different regions. Except for cephalomycetes Rain Water, the second molds in Zhoushan are basically in a semi-sunny and semi-overcast climate. When the moldy rainy season first came, it was really frightening to live a life. The first thing to do every morning was to carefully observe the changes of the orchid in the orchid garden. When everything was calm, it began to water and comb the orchid leaves. Looking at the new buds of orchid and orchid raised by myself day by day, rippling a kind of inexplicable pleasure in the depths of my heart.

On the first day after entering the three molds, there was a torrential rain, which cleaned up the dreary climate for many days, and the orchid in the orchid garden grew madly in the rain for a while. Orchid has the characteristics of soothing, although the spring wind and rain, but the relative temperature is not high, the earth is still slowly releasing the cold snap inhaled in winter, orchid can only be leisurely adjust the pace of recovery and little progress. In early summer, as long as the flange is conditioned, it will enter a period of rapid growth. How you want this environment to last longer, but this year is a short-mildew rainy season.

In July, most parts of our country began to gradually enter the midsummer period of high temperature, and the temperature in Zhoushan is also high above 30 degrees. Although Jiangnan is not yet moldy, it makes people feel the approach of a hot summer. Orchid friends will not forget the hot summer last year, many boutique, high-quality orchids because of the relentless heat and hate to return to the west.

Orchid not only has the characteristics of soothing, but also has the characteristics of high temperature lag. The best temperature for the growth of Cymbidium is about 20 to 28 degrees. Higher or lower temperature is not conducive to the growth of Cymbidium. When the temperature exceeds 32 degrees, Chunlan will lag. Under the pressure of high temperature, orchid adopts a complex process of slowing down metabolism in order to achieve physiological balance, but the physical dynamics of orchid is in the most exciting part of the period, and the consequence of high temperature is the increase of rising effect. The increased upwelling will consume a lot of water and some of the nutrients that have just been accumulated, so the orchid is in a rather disadvantageous growth cycle. If the high temperature weather is a normal atmospheric circulation and the duration is normal, Laneng can safely pass through the midsummer into the crisp autumn and usher in the second growth period.

The distant orchid is in the anti-theft window grille of the balcony, directly facing the threat of high temperature. In order to reduce the natural temperature, the aluminum alloy cover of the roof of the anti-theft window grille is completely sealed with a two-centimeter thick foam plate in order to block the heat from the sun exposure on the aluminum alloy plate. Each anti-theft window grille is equipped with a small ceiling fan with a diameter of 30 centimeters, no matter whether it is windy or unwindy, it always keeps spinning leisurely. Anyway, the power consumption of the small ceiling fan is only nine watts per hour, and it can afford it in the distance. In exchange for the elegant appearance of orchid leaves swaying and dragging in the breeze.

High temperature plus the rising effect of orchid. In summer, if watering is not timely, it is easy to cause dehydration of orchid leaves, while more watering is easy to cause the root of orchid root to be steamed and cause root necrosis. In addition to the external environment, ventilation in the orchid basin has also become the most important factor in the success or failure of the year. At this time, if the Reed head of the orchid is buried too deep, you can slowly pick it out with a bamboo stick. It is best to expose the Reed head to about 1/2 on the plant surface. Reducing the burying depth is conducive to cooling and ventilation.

In midsummer, if there are black spots in the upper part of the orchid leaves, most of them are caused by excessive ventilation and water supply, while the black spots in the lower part of the leaves are often related to the invasion of bacteria caused by too much water. The humidity of the orchid room in summer is a double-edged sword, so that the flange leaves are full of phosphorescence, on the contrary, the disease is plagued with disease and even causes the seedlings and grass to fall. Humidity should be appropriately reduced during the day when the temperature is high, and can be appropriately increased when the temperature is slightly lower at night, which may have something to do with the reason why the ancients watered in the middle of the night or in the early morning.

Summer is a colorful summer, and many tearful stories are related to summer. Summer is a very sad summer, people have to pay a lot of energy, not to mention watering the orchid is enough for orchid friends to sweat for a while. Summer is a troublesome summer, and many unexpected difficulties and helplessness will occur in summer. The summer is hot, accompanied by orchid; orchid is human, natural and auspicious.
