The grafting method of crab claw orchid won't look at it all.

There are two main ways of propagation of crab claw orchid, cutting and grafting, although the survival rate of cutting is high, but the cultivated plants are not beautiful, so generally use grafting method, the following editor to tell you about the grafting method of crab claw orchid:

The grafting method of crab claw orchid:

1. Grafting time

The grafting time is in late spring and early summer, or in late summer and early autumn, but the grafting in late spring and early summer is the best. It is the most suitable in Zhejiang in mid-May, when it is the peak growing season of crab claw orchid and cactus, and ideal scions and rootstocks can be selected. in addition, at this time, the temperature is suitable, the affinity of scion and rootstock is strong, not easy to rot, and the survival rate is relatively high.

The scion should choose the vigorous growth of the tender branches, choose the part with the top is the best, about 8-10 cm long. Use cactus as rootstock, choose an one-year-old single cactus specially used as rootstock, about 15cm long, and the meat should be thin and moderate.

2. Grafting steps

The main results are as follows: (1) the cactus branches with one-year growth strip type, not too thick meat but exuberant growth and no diseases and insect pests are selected as rootstocks, and the length is between 8~12cm. Take it from the matrix, cut the lower end into a flat mouth, cut it into sandy soil, cultivate it for 2-3 months, and then make a grafted rootstock after survival.

(2) the strong mother plant of crab claw orchid was selected, from which the tender top branch with nodes was selected as scion, and the length of the scion was 3~4cm (the growth potential of scion was weak after sprouting). Cut the lower sides of the scion into a wedge with an alcohol sterilized blade, and the cutting length is about 0.8~1.2cm.

(3) the cactus selected by grafting should be wider than scion. The top of the cactus can be cut flat or not. When grafting, choose a thin bamboo stick as wide and narrow as the scion, insert a 1.5~2cm deep groove vertically down from the middle of the top of the cactus as the interface, and then quickly insert the scion into the interface of the rootstock.

3. Management after grafting

The grafting of crab claw orchid is only the first step of grafting propagation, and the future management is also very important for the survival of crab claw orchid.

(1) to do a good job of shading and avoiding light. Just picked up the crab claw orchid, because it has just separated from the plant, it is very easy to wilt due to too much water loss, so it must be moved to the shade at this time to reduce water evaporation.

(2) after grafting, appropriate amount of water should be watered to keep the basin soil slightly wet. Under normal circumstances, watering once every three or four days, be careful when watering to avoid water entering the incision.

(3) timely fertilization. After grafting, if it does not wilt after half a month, it shows that it has survived, and appropriate amount of fertilizer can be applied after a month to provide nutrients for plant growth in time.

(4) build a fight in time. After the grafted crab claw orchid survived, because of its soft stem, it should be fixed and properly bound in time in the process of its growth, so as to maintain the integrity and beauty of the plant shape.

(5) it is necessary to prevent diseases and insects in time. Crab claw orchids are prone to rot. If rot occurs, it can be scraped with a sterilized knife and disinfected with sulfur powder. The insect pests of crab claw orchid are mainly shell insects and aphids.

If it occurs, when the quantity is small, it can be removed with a brush; when the quantity is large, 1000 times of omethoate EC or 50% fenitrothion EC can be sprayed and sprayed again every 20 days. You can also use washing powder to add water by weight ratio of 1 to 150, spray once every 5 days after mixing well, and spray continuously for 2 times 3 times to prevent and cure.

Crab claw orchid reproduction with the best way of grafting, the growth of the plant is more good-looking, whether it is alone to watch or decorate the room can have a very good effect, crab claw orchid grafting method introduced here, I hope it will be helpful to everyone.
