How to grow an orchid 5, how to grow an orchid

Straighten out the roots of the orchid grass first, cut off the empty stem roots and rotten roots, and then plant them in deep pots and cover them with orchid grass soil, press them with water, and water them thoroughly, and put them in a breathable and semi-shaded environment.

When planting orchids, it is necessary to plant the first plant in the soil mixed with coconut shells, perlite and charcoal, and then place the planted plants in an environment with scattered light, so that the orchids can photosynthesize for 4 to 6 hours a day.

How orchids are grown.

1. Mix soil.

Before planting orchids, it is necessary to use finely ground coconut shells, perlite and charcoal, mix and mix according to the ratio of 4:1:1, and then place the prepared soil to dry under strong light for 1 to 2 days to eliminate the germs and pests in it, and provide a safe growth environment for orchids.

2. Provide light.

When the orchid is planted, it should be placed on the balcony with bright light indoors, so that the plant can absorb 4 to 6 hours of scattered light every day to promote the growth of branches and leaves.

3. Replenish water.

In the process of maintaining orchids, it is usually necessary to water them every 5 to 7 days, but the water evaporates faster in summer and the air is drier, so it is necessary to replenish water for orchids once a day, and spray water for the branches and leaves of the plant at night to avoid dehydration and dryness of the leaves.

4. Paving.

When the orchid is planted, you can cover the soil surface with colored stones or moss to prevent rain from washing the soil, resulting in excessive acidity, and at the same time increase the aesthetics of the plant, pay attention to the paving, you need to loosen the soil for the orchid every 2 months to avoid soil compaction, affecting the growth of the root system.

There are many varieties of orchids. This is the cultivation technique of orchids in general:

Cultivation method: Orchid bonsai ** collection (18 photos) Separate orchid bushes, do not dismantle too sporadically, each bush has at least 3 5 seedlings, it is best to keep annual, biennial and triennial plants in the same cluster.

Cushion pot The bottom of the pot is covered with a tile to cover the drainage hole, and then gradually filled with bricks, tiles or shells, in which the large gap is filled with mud grains or bean stones, generally about 1 2 1 3 of the height of the pot. The clear height of the upper remainder is about 10 15 cm, which is reserved for the cultivation of soil. The specific height should be determined according to the species of orchid, the length of the orchid root and the height of the pot.

The bedding should not be too dense and too solid, and a little porosity should be retained. It has been proven that some new roots grow well in the pores of the bedding.

Planting on the bedding layer, first fill in 2 3 cm of culture soil, slightly compacted by hand, you can put the orchid upright at the mercy of it, according to the size of the plant and the pot, you can plant several single plants, 2 bushes, 3 bushes or more bushes in a pot. 3. The bush should be planted into a full momentum. 4 bushes can be planted into a square, and 5 bushes should be arranged into a plum blossom shape.

The roots should be stretched naturally, and the leaves should be draped in all directions. Slowly put the root into the pot so that the root stretches naturally, and try not to touch the inner wall of the pot. After the orchid plant is potted, the posture of the orchid plant is gradually fixed.

If you plant a bunch of potted plants, the old false bulb should be on one side, so that the new shoots have room for development. If there are several clusters in a pot, the old false bulbs of each bush should be relatively concentrated in the middle of the pot, so that there is enough space for new roots and shoots to develop outward.

Fill the soil When planting, hold the leaves with one hand, add nutrient soil with the other, hold the base of the orchid plant and lift it slightly upwards to stretch the root system, and shake the orchid pot at the same time. Let the cultivated soil penetrate deep into the rhizosphere; Continue to add soil and shake the pot to adjust the position and height of the plant. Press along the edge of the pot with your hands, but do not hurt the roots too much, continue to add soil and squeeze until the soil on the surface of the pot is 2 3 cm higher than the mouth of the pot, slightly steamed bread shaped.

The culture soil should cover the roots of the whole Dulan, cover the base of the false bulb, and fill the depth of the soil, the traditional belief is: Chunlan should be shallow, Huilan should be deep, but generally not buried and the leaf base on the false bulb is the degree. When the newly-haired orchid grows in the mountains, it leaves a clear mark on the soil surface, which can be used as a standard.

The size of the pot should also be commensurate with the size of the plant, and the size of the plant should not be large and the plant should be small and few, nor should the pot be small and the plant should be large and many. In general, the number of plants is expected to be full after 2 to 3 years. The size of the plant is commensurate with the height of the pot.

It is not only conducive to growth, but also meets the requirements of ornamentation.

After planting, you can spread a layer of small stones or moss on the surface of the potting soil, preferably high-quality moss under the forest, which is not only beautiful, but also can regulate the water, and can also protect the leaf surface from being polluted by muddy water, and the new shoots will not be infected with the germs in the soil and rot their hearts; In addition, it can also slow down the erosion of the potting soil by rainwater and keep the potting soil loose.

Watering After the planting is completed, the first water must be watered, the potting soil must be soaked, the water droplets should be small, and the impulse should not be large. If it is placed in a basin of water, do not soak it for too long. Once the potting soil is soaked, the pots are immediately removed and then placed in a shaded place for maintenance.

We generally raise orchids in pots. Because the traditional planting material is orchid mud, the mud foam is very fine. In order to aerate the roots, a clay basin is used.

Since the roots of orchids are slender, it is better to use high-waisted open flared round pots. In order to facilitate the drainage, the diameter of the basin bottom hole should be large, and in order to strengthen the air object inside and outside the basin, the basin base should be high and upright.

Orchid mud: The soil accumulated in the recesses of mountain rocks after the leaves rot, which has the characteristics of softness, drainage and fertility. The pH value is in between.

However, the orchid mud on the market is not completely desirable, and after coming back, you will add some coarse sand and large pieces of burned waste cinder, which will make it easier to make the orchid soil breathable and soft, and easy to survive.

1. Planting: Excellent varieties should be selected for ground planting, with strong drainage performance and fertile sandy soil. Spraying the soil surface with the new high-fat film can protect moisture and waterproof evaporation, sunscreen and drought resistance, heat preservation and anti-freezing, prevent soil layer compaction, suffocate and isolate the source of diseases and insects, and protect the seedlings to thrive.

2. Light, weeding, watering, fertilization: orchids like shade, should not directly receive too strong light, summer and autumn to shade, orchids have higher requirements for fertilizer and water, keep moist at any time, reasonable fertilization according to demand, spraying new high fat film to protect fertilizer and moisture.

3. Plastic pruning: Orchids mainly cut off dry branches, diseased branches, cross branches, and overly dense branches, which obviously affect the shape of the tree, as well as thin excess flower buds. Apply callus antiseptic film on pruning wounds to protect the growth of wound healing tissues and prevent the infection of rot bacteria.

4. Pest control: common diseases of orchids, white silk disease, anthracnose, scale insects, take reasonable measures, orchids should not use pesticides, use some pollution-free pest control methods, easy to take materials, simple methods, will not pollute, no pollution, no ***, etc.

5. Flowering control: orchid is a precious ornamental plant, the air must circulate, the appearance is beautiful, spraying flowers in the flower buds can promote strong flower buds, petal hypertrophy, gorgeous flower color, rich flower fragrance, and prolonged flowering period.

Planting orchids is very particular, to taboo in the sun out of the time of watering, you can fix a month or two to the orchid to change the soil (remember to change a clean pot), if the leaves are yellowed to dispose of immediately, and now that the weather is cold, you can wrap its tender teeth with cotton and scatter.
