Monthly operation of orchid cultivation

Shen Yuanru's "Orchid" 27 Orchid cultivation monthly work in January according to the frost and snow conditions over the years, this month is the time of the final frost and the first snow. as the strong cold snap continues to attack, it is the coldest period of the year. In the south of the Yangtze River, except for minus 10 ℃ in a few years, the monthly average temperature is mostly about 4 ℃. In order to keep potted orchids growing healthily indoors and safely through the winter, doors and windows should be closed at any time and cotton curtains should be added to prevent cold air from invading. To strengthen the work of indoor warmth, the room temperature had better be kept at about 10 ℃ during the day and at least 5 ℃ at night. If the weather is sunny and the wind is small, and there is no dripping freezing outside, all the cotton curtains of the south window are removed, cover the window around noon, change the fresh air, and close immediately for about half an hour. If individual pots are found to be dry, they can be watered at noon. Orchids with buds should be placed in a sunny place. Although we met the Beginning of Spring in the first ten days of this month in February, there was still a spring cold from time to time. The monthly average temperature is 1 ℃ higher than that of the previous month, and the minimum temperature is still about 3 ℃ below zero, so we should also pay attention to heating and keeping warm. On a sunny day when there is no rain or snow, the south window can be half-opened after 09:00 (if there are multiple rows of windows facing south, only one of them can be opened). Individual spring orchids, such as spring blossoms and orchids, should be exposed to more sunshine before budding to promote bright coloring. For example, if there are three or four buds in a pot, the weak leaves one or two, but it depends on whether the hair is in the right position or not. Often change the direction of the orchid, lure the stamens to open just in the orchid leaves. Lan Rui gradually elongated to keep the basin soil moist. On a sunny and warmer day, spray and wash the dusty orchids with leaves in the sun to remove the dirt. Spring orchid varieties were recorded at any time, and the reasons were analyzed according to the indoor temperature and humidity. Day by day, we should pay attention to the changes of the depth, thickness and thickness of each layer of bract clothing, such as rib pattern, sand halo and color during the stamen elongation of Chunlan orchid, so as to gain the experience in identifying the shell, color, sand halo and the evolution of tendons and patterns of "falling mountain new flowers". At the end of the decade, he began to sort out the outdoor orchid cultivation site. The temperature in March is getting warmer in spring, with a monthly average temperature of 7 Mel and 8 ℃. Chunlan is in full bloom one after another, selecting exhibition varieties and arranging exhibition venues. After "stinging", the figs, Cymbidium and Cymbidium will be moved to outdoor cultivation, which still need to be protected at night. If there is a spring cold attack, but also move back to indoor maintenance in time. After "the Spring Equinox", cymbidium can be transferred and cultivated outdoors, and if the temperature is too low, it should be moved back in time to prevent the stamens from becoming stiff and the spring orchids in full bloom. In the last ten days, prepare to prepare the potted orchid mud. Check and repair shading tools. The non-bud orchid was fertilized for the first time (mainly thin). In April, the outside temperature is gradually rising and getting warmer, and the frost and snow has stopped. The average monthly temperature is about 14 ℃, with light rain and more southwest winds. Pay attention to the daily adjustment of dry and humidity. In case of long rain, Cymbidium is moved under the canopy for maintenance. The curtain work began in the middle of the month. This month is the most suitable time for turning pots and changing mud and dividing plants to propagate. The temperature increased gradually in May, with a monthly average temperature of about 18 ℃. The curtain will be placed for shade in the morning from the end of the day. Pay more attention to disease prevention and pest control. The seed bud is about to break the soil and grow, so it can be fertilized. The average temperature in June is about 24 ℃, and the temperature is getting hotter. At this time is entering the Meiyu period, rainy and humid, when overcast and sometimes Yang, should pay attention to the curtain and curtain work at any time. Due to the high humidity, Cuiyun grass grows luxuriantly and needs to be thinned for the first time. The seed buds break the soil and grow one after another, pay attention to the color and transformation of the bud tips of each variety at any time, and accumulate the empirical knowledge of identifying varieties. During this period, the orchid should be overcast, and the cymbidium can be slightly positive, which is conducive to the growth of the new grass. To top dressing. In July, the climate turned to the hot season, with an average monthly temperature of about 29 ℃. Strengthen shading and switch to secret curtains. Put the curtain in the morning light and close the curtain only when there is no sunshine on the orchid platform. Strengthen ventilation and cooling work. At the end of this month, when the typhoon season, strengthen leaf protection. Pay attention to the basin soil moistening and mixing, spray leaf water many times. Summer and Qiulan blossom one after another, ready for display. The temperature in the first ten days of this month is similar to that of the previous month, with a monthly average temperature of about 26 ℃. It is still in the typhoon season, with many showers. Pay attention to the safety of the scaffolding and strengthen it. Sometimes there is muggy heat, and it is still necessary to strengthen ventilation and shading. Pay attention to watering, disease prevention, pest control and other work. All kinds of orchid buds show the soil surface. New roots and new grass have grown. There are often cracks in the basin surface, which can be filled up at any time. The climate in September is turning to autumn, with a monthly average temperature of about 24 ℃. The daily curtain can be released late and closed early. During the period of "White Dew", except that the occasional "sweet clover steaming" phenomenon must be shaded, the shading work is generally finished (it should also be based on the surrounding environment of the orchid cultivation site). Such as the sudden change of hot and dry climate-commonly known as "water chestnut dryness", we should strengthen watering and keep the basin soil moist, otherwise, in this case, the plant is most vulnerable to injury (light buds dry, heavy roots, leaves withered). Continue to do a good job in disease prevention and pest control. Some of the thin bluegrass were fertilized for the last time. The second half of this month is the "the Autumn Equinox" period, which is another most suitable period of the year for pot-turning and ramet reproduction. The average temperature in October and this month is about 18 ℃, and the temperature is turning cooler in autumn. Watering depends on whether the basin soil is dry or wet. Renovate the basin Cuiyun grass. Remove the weak autumn buds. If there is an autumn bud, you can chase the light fat again. Get more sunshine. The average temperature of the whole month in November is about 11 ℃. It is getting cold in the morning and evening. We should pay attention to frost prevention. Clean the orchid room and prepare the equipment to enter the room. All kinds of orchids with flowers and grass cultivated by Reed head are moved under the porch or along the window at the end of the decade. At the end of the decade, there are flower cold orchid, new year orchid into the room for maintenance. December enters a cold winter this month, when frost and snow damage has occurred in Wuxi in the past two decades. Before the "heavy snow" solar term, all orchids must enter the room. According to the cold weather, switch the window properly. Pay attention to the indoor cold protection and warm work. Compared with the number of new grass, buds and growth potential of each pot of bluegrass over the years, the experience of Yilan in one year was summarized. The above applies to the south of the Yangtze River in China. )
