Glass greenhouse. The greenhouse is a very applicable greenhouse, the main technical parameters according to the height of the orchid, living habits, preference for temperature and humidity to build.

The steel frame of the greenhouse is ready-made, assembled according to the requirements, and the span is 6 meters, 8 meters and other specifications, which can be selected according to needs. Set up a shelf and cover it with a shade net, please choose a shade rate of 85%.

1. Place. The place where the orchid is placed is very important, and it directly affects the growth and development of the orchid. Orchids are generally placed in the open field in spring, summer, and autumn (in the shade of the open field in summer) and indoors in winter.

It is best to be outside in an open area with humid air. There should be plenty of light indoors, preferably facing south. In this way, it is beneficial for orchids to grow.

It is best to place the orchid basin on a wooden frame or table, not on the ground.

2. Shade Orchids are mostly semi-negative plants, and most species are afraid of direct sunlight and need proper shade. Orchids are in early and mid-April, and more sunlight can be used to promote their growth. Proper shade should be provided after late April.

The varieties with erect leaves in the summer orchid and autumn orchid should be placed in the south of the shade place, so that they can be exposed to more sunlight. Weeping autumn and spring orchids are better exposed to two hours of light every day. From June to September, shade should be provided early every day, such as reed curtains can be used dense curtains or two layers of thin curtains. After October, the weather becomes cooler and the sun is weaker, so you can postpone the shading, but you still need to pay attention to the shading work around noon.

3. Rainproof Orchids can be drenched in light rain, but they should avoid mildew rain, showers or continuous rain. In the mildew rainy season, it is especially necessary to do a good job of rain prevention. From late June to mid-September, showers are common.

If the rain is short, and the rainfall is small, it should be watered more in the evening to discharge the heat in the pot, otherwise it will cause damage to the Fengzhihong orchid, and even rot the roots and die. If the sun comes out again after the shower, it is necessary to shade in time to prevent the rise of heat on the ground and affect the growth of orchids. In the rainy season, it is the stage when orchids extract leaf buds, and if the potting soil is too warm, the leaf buds will not grow well or cause diseases.

At this time, a small amount of plant ash can be sprinkled to adjust the moisture of the potting soil.

4. Watering. In the growing period (May to the end of June) should be properly watered, the leaf bud stage (about March to April) and flowering period (about March to April) should be appropriately watered, and the dormancy period (winter) should be watered less or no watering. Pots with large pots and small orchid plants should be watered less, and potted plants with large plants should be watered more.

When the climate is hot and dry, it should be watered more appropriately, and when it is cold and humid (such as mildew rainy season, etc.), it should be watered less or no watering. If the orchid is newly dug from the mountain, if the root system is sparse or there are many broken roots, it should be watered less to make the potting soil dry a little, so that the roots will not rot, which is conducive to extracting new leaves. Watering time:

In summer and autumn, it is advisable to water after sunset to dry the leaves of orchids before nightfall, or in the early morning; In winter and spring, it is better to water around sunrise.

The advantages of balcony orchid cultivation are smooth air, abundant sunshine, and easy flowering. The disadvantages are that the light is too strong, the temperature is high, the water evaporates quickly, the orchid leaves are easy to be burned and banana leaves appear, and they are easily infected with anthracnose, soft rot and brown spot. So what should you pay attention to when raising orchids on the balcony?

1.Pay attention to shade, orchid grass likes shade, when raising orchids, it is necessary to consider the shade of orchids, you can plant some climbing plants on the balcony, such as creepers, etc., or triangular plums, etc., which can greatly reduce the illumination, but also beautify the balcony environment, both of both. In addition, if the balcony sits north and faces south, it is necessary to prevent the west from the sun.

The sun in summer is particularly strong, the heat is poisonous, and the bluegrass is the most taboo, so it is necessary to avoid the west as much as possible, and you can put a shade net on the west side; Or put a pot of two or three meters high evergreen plants such as orange trees, osmanthus trees, etc. on the west side of the balcony, which has a good shading effect.

2.Increase air humidity, balcony air flow is large, the temperature is high, the water evaporates quickly, the growth of orchid grass needs a certain amount of moist air, especially in summer to increase humidity. Put a few buckets on the balcony, or sprinkle more water on the floor, and if possible, you can install a humidifier.

3.Keep warm and cool, the temperature of the balcony is relatively low in winter, and it is easy to be damaged by the northwest wind and frost. If you spend the winter on the balcony, you should cover the balcony with a transparent agricultural film, which can protect against frost.

In the summer, it is necessary to consider cooling down, install wall fans on the wall to enhance air flow, and if you install a sprayer, it will be more effective.

4.Sterilization and disinfection, the balcony is exposed, the orchid grass is susceptible to outdoor germ infection, it is necessary to be sterilized and disinfected frequently, and we must pay attention to the sterilization of the orchid leaves; Second, we should pay attention to the disinfection of potting soil. Orchid leaf sterilization uses systemic pesticides, which can prevent the stomata of orchid leaves from being blocked; Potting soil disinfection can be done by using sodium disulfonate, thiophanate-methyl, chloramphenicol, and potassium permanganate to irrigate the roots.

Pay attention to the time of purchase:

Orchids are alive, so it takes time to adapt to the environment, of course, the longer the adaptation time, the better, the shorter the adaptation time, sometimes it can't adapt, of course the orchid will die.

Ingredients for changing pots:

The orchids in the greenhouse grow up in the medium, aquatic plants and relatively loose and breathable materials, therefore, when changing the pot, do not be too different from the original material, otherwise it will cause the orchid to rot the roots, but because the orchids are now purchased with bare roots, so I don't know what materials are used to raise orchids, which will also affect the survival rate of orchids, so when buying orchids, you should ask the seller to tell what materials are used to plant, and then make adjustments with reference to your own environment to improve the survival rate of orchids.

Choice of fertilizer:

Most of the orchids in the greenhouse are made of chemical fertilizers, which can be directly absorbed, and are not necessarily decomposed by bacteria like organic fertilizer, so do not put organic fertilizer as base fertilizer when buying greenhouse orchids when planting, otherwise the orchid root will not be able to adapt to it for a while and rot the roots.

To be sterilized regularly:

Because the greenhouse is in a high humidity environment, the germ infection is very fast, so it depends on regular sterilization, so the resistance of the orchid to the germ is naturally not as strong as the balcony orchid, so after buying it back, it is natural to sterilize it regularly, and after a certain period, look at its growth and then gradually reduce the medication.

Sterilization treatment should be carried out (exposure to the sun is sufficient) to prevent the occurrence of diseases. Orchids are most prone to white silk disease in rainy and high temperature seasons, which can be prevented by spraying Tobuzin 800 times or Bordeaux solution. If the disease is severe, Tobuzin can be released 500-750 times, and sprayed every 7-10 days.

Among the insect pests, scale insects occur the most, and this insect is attached to the base of the leaf, if scale insects are found, they should be removed in time. To avoid scale insect infestation, it is available from April"1059"2000 times liquid control. In order to inhibit the occurrence of orchid diseases, in addition to the usual dry and humid potting soil should be properly controlled, mud pots should be used as much as possible in the selection of pots, and less glazed pots should be used.

Especially for the newly dug orchids with poor growth, they must be planted in mud pots. Doing so makes the potting soil dry out easily, which can promote the growth of orchids and reduce the incidence of disease.
