Crab claw orchid breeding methods and precautions:

1, fertilizer

Insufficient fertilizer is just not vigorous growth, while excessive fertilizer is to make the plant may die. Crab claw orchid should not use chemical fertilizer, usually their own composted rot through the thin liquid fertilizer, autumn to flowering can be increased in the amount of water and fertilizer. Summer high temperature air dry, coupled with poor ventilation, affecting the growth of the plant, during this period to choose ventilation and light shade placed, not easily moved.

Should be less watering, avoid rain, so as not to rot the roots, can be sprayed to the plant and the ground near the plant, in order to increase the humidity of the air, reduce the temperature. Growing season to keep the potting soil moist, avoid too dry or too wet. Spray foliar water when the air is dry, especially during the period of pregnancy bud spray foliar water is conducive to more pregnant buds.

2, temperature

Crab claw orchid growth temperature of about 25 ℃, more than 30 ℃ into the semi-dormant state. In winter, the room temperature is maintained at about 15 ℃, below 10 ℃, sudden temperature changes and temperature difference will lead to flower buds; flowering temperature of 10-15 ℃ is good, and moved to diffused light at the maintenance, in order to extend the ornamental period.

3, change the pot

Crab claw orchid in March-April every other year to change the pot, the potting soil to loose fertile permeability good slightly acidic soil is appropriate, the bottom of the pot first layer of fine sand, in order to facilitate the seepage of water, combined with the change of pots sparse growth of weak branches, and moderately short cuts in order to facilitate the sprouting of young and strong branches, blooming and flourish.

4, pruning

After the flowers are gone in the spring, cut off 3-4 pieces of stem nodes under the residual flowers in a timely manner, and at the same time, thin out some of the old stems and over-dense stem nodes, in order to facilitate the ventilation and home maintenance; in the cultivation of Crabapple Orchid, sometimes from the top of a node will grow 4-5 new branches should be deleted in time 1-2. Stem nodes bearing too many weak flower buds, should also remove some, can contribute to the flowers of uniform size, bloom vigorously.

Cultivate 3-5 years of plants, can be 3-4 thick lead wire as a pillar, inserted into the soil along the wall of the pot, the upper part of the 2-3 layers of round bracket, the section of the branch bundled in the circle, to avoid the stem section of the superposition and scattered, and at the same time delete some of the jagged stem, so that the plant is umbrella-shaped, which can be beneficial to the photosynthesis and the display of the ornamental.

Expanded:

1, disease and insect control:

Crabapple orchid often occurs anthracnose, rot and leaf blight damage to the leafy stems, especially in the high temperature and high humidity, the onset of serious. Serious plants should be pulled out and centralized burned. At the beginning of the disease, use 50% carbendazim wettable powder 500 times liquid, every 10-15d spray 1 time, *** spray 3 times.

In case of serious damage, the surface of the leafy stem is covered with white shells, which makes the plant grow weak, and the damaged part is yellowish-white, if the damaged plant is light, it can be scraped by bamboo slice, and when it is serious, it can be sprayed with 25% imidacloprid emulsion 800 times. When red spider damage occurs, spray 1000-1500 times of oxidized lecithin liquid to prevent and control.

2, the main value

Crab claw orchid section stems are often too long, and pendant, so it is often made into hanging orchids for decoration. Crabapple orchids bloom at Christmas and New Year's Day, and their hanging shape makes them suitable for window sills, entrance of gardens and exhibition halls. However, because of the way of feeding, some crabapples are regulated to bloom in October.
