Management after flowering period of Huilan

After the end of the flowering period of Cymbidium, the cymbidium buds cultivated in the natural environment in most areas have been unearthed. The annual round-the-clock bud stage management is an important work here. There will be the Beginning of Summer in May. Lesser Fullness of Grain has two solar terms, and the monthly average temperature is relatively stable at about 22 degrees. The vast areas of the south enter summer in the first ten days of this month; Jiangsu and Zhejiang generally enter summer in the middle and late ten days; and some parts of the north enter summer at the end of the last ten days. There is generally a lot of precipitation this month, and the southern region has begun to enter the plum. The best time for the growth of cymbidium has come. To grasp the critical period of the growth of cymbidium, it is particularly necessary to do the following management.

Shading: with the rising temperature, the shading of Huilan usually starts from 25 degrees to 28 degrees. Because of the consideration of everyone. The environment of cultivation is different in different places, so it cannot be uniform a thousand times. At the same time, Cymbidium is a sun-loving plant, so it is necessary to do a good job of shading according to the actual situation. It is most appropriate to use 50% shade net in Jiangsu and Zhejiang this month. You can get full light before 10:00 in the morning, then pull up the shade net and open it at 4 p.m. This is a bit troublesome to operate, but it is very beneficial to the growth of Huilan. If the use of the sun plate (BVC) of the orchid room, because it can filter out more than 90% of ultraviolet light, coupled with the orchid room's better ventilation conditions, as long as there is no explosive high temperature, then 12:00 to 3 pm appropriate shade, that is the best way to shade. Conditional orchid friends, it is best to use bamboo curtain or Reed curtain to shade, thermal insulation effect is better than shade net, might as well have a try.

Watering: Cymbidium prefers a wet and dry growth environment. Dry and wet is the key to watering Cymbidium. Its water demand is less than that of other orchid species, not because of its small bulb. The leaves are long, mistakenly thinking that more water is needed to meet the needs of their growth, which will be counterproductive. Because most of the cymbidium is native to the sunny high slope, the root system is well developed, wet and dry quickly after rain, and sometimes it can grow tenaciously without rain for the whole month. Although it is not afraid of too much water, but too much and useless is also an unnecessary waste of manpower and water resources, and sometimes because the basin is often wet and dry, causing unnecessary man-made harm, isn't that thankless? In the budding stage of Cymbidium, it can be moist properly. The measure to be mastered is: after the basin noodles are dry in sunny weather, you can drench the basin noodles with small water in the early morning or evening of the next day, and then pour a lot of water next time when the basin is slightly dry. This can not only ensure the prosperity and growth of small buds, but also overcome the taboo of often wet in the basin. If you master it properly, the effect is obvious.

Fertilization: after the new buds of Huilan are unearthed, a little pause will lead to new roots. at this time, the application of fertilizer will be of great benefit to promote the growth of cymbidium flowers. According to thin fertilizer. According to the principle of timeliness, foliar fertilizer can be sprayed with fertilizers such as potassium dihydrogen phosphate or Xishuo, or fully fermented organic fertilizer can be used. Generally speaking, the times of spraying can be determined according to the strength of cymbidium seedlings. Because the newly changed pots and newly flowered cymbidium are not yet round and semi-dormant, the absorption function of fertilizer is limited, so there is no need to fertilize them. At most, it is enough to spray foliar dilute fertilizer at the right time. The organic fertilizer based on nitrogen fertilizer should be selected for the root fertilizer, and nitrogen fertilizer should be applied at the seedling stage of Cymbidium, which is beneficial to the exuberant growth of stems and leaves. Such as chicken feathers. Soybean Milk。 Cabbage cake. Green grass. The leachate of bean hulls and so on are all organic fertilizers with considerable nitrogen fertilizer ingredients. When in use, inorganic fertilizers with a little trace elements are added and watered with about 30 times water dilution, and the next day the water can be returned.

Ventilation: with the increase of air temperature, the ventilation of orchid cultivation site needs to be strengthened. Especially in the humid and windless climate, it is particularly important to do a good job of ventilation. The ancients fixed the first essence of raising Christine on ventilation, which is indeed the best. The ventilation of orchid cultivation site is directly related to the success of Huihui. balcony。 Rooftop Yanghui can use micro-fans to regulate ventilation; large-scale orchid farms generally use industrial exhaust fans to promote air circulation. It is necessary to be before and after. Left and right. The upper and lower surfaces are ventilated, so that the cymbidium can breathe circularly, spit out the old and accept the new. The wind requirement of natural ventilation is better about the second grade, the breeze is light and the leaves of cymbidium are swaying, which is undoubtedly very beneficial to the growth of cymbidium flowers. Can you think of it this way: the higher the temperature, the greater the humidity, the more ventilation and ventilation should be strengthened. If the key condition of ventilation and ventilation is ignored, it is impossible to raise Cymbidium well. This is an eternal law through the ages.

Disease prevention: the resistance of Cymbidium is slightly stronger than other orchid species, and it is not easy to get sick in general. For weak seedlings and Cymbidium with wound infection, germs are easy to swoop in and have to be prevented. To give priority to prevention, we should start from multiple aspects. The common methods are to clean and maintain the sanitary condition of the orchid room, sprinkle the ground with lime powder, spray the surrounding environment, spray the cymbidium after rain, and so on. There is no doubt that these are good methods, and they have indeed played a due role in inhibiting the disease of Cymbidium. But all these methods are not the best relatively speaking. Really active prevention, but also need comprehensive prevention, that is, strong seedlings and disease resistance. If you can raise Christine, more in the light. Be ventilated. Water it. Fertilize. It is easy to use medicine and so on. Just right, then the seedlings must be very strong, and the natural resistance will be enhanced. For this reason, drug prevention must be based on strong seedlings, which is a common goal for us cymbals.

Pest control: due to the increase of Rain Water and the rise of temperature, insect pests began to multiply. Aphids are produced in a high-temperature and humid environment, reproduce quickly and harm orchid leaves. Once found, they are sprayed with omethoate. Scale insects will break out in hot and muggy weather, and the trend is fierce. as soon as it happens, they will be killed three times in a row with pyrethrin pesticides or special scale control agents, once every three days, in order to wipe them out. The mite is a small pest, which is difficult to see without paying attention. It bites the base of the heart leaf and does great harm, so it can be treated with triclofenac. Cymbals appear at night and bite the tender leaf buds on the cymbidium basin, and the mucus of the worm is easy to stick to the leaves of the cymbidium, which hinders viewing, but pesticides have no effect on it. Only after it is caught crawling on the ground, it will be cut with a nail (or knife). Another way: sprinkle it with salt and marinate it. In addition, ants. Nematodes. Earthworms and other insects can be driven away by soaking in the basin, induced by bones, and irrigated with pesticides.

In May, there is a poem in the management of Huilan: the flowers of Huilan are blooming and peaceful, and they gradually feel the pride of the sun. Rectify the flower protection barrier and clean frame, and compete for the bamboo nest in half-yin.
