The latest propagation method of crab claw orchid

Crab claw orchid is an epiphytic succulent plant of the genus Cactus. It is a common ornamental plant. It is cultivated in parks and flower beds all over China. It is often grafted on Tianyi or other rootstocks in order to obtain luxuriant plants. Propagation methods include cutting propagation, sowing reproduction and grafting reproduction. The production is mainly based on grafting propagation. Let's take a look at the propagation methods of crab claw orchid.

Cutting propagation of crab claw orchid

When cutting and propagating crab claw orchid, the sturdy and thick stem nodes were cut off and left in the shade for 2 to 3 days. After the incision was slightly dry, it was inserted into the sand bed. The substrate was peat and sand with a proportion of 4:1, and the bed temperature was 15: 20 ℃. The humidity of the inserting bed should not be too high, so as to avoid excessive wet decay of the incision. The roots began to take root 2-3 weeks after planting, and potted plants could be planted 4 weeks later.

Sowing and propagation of crab claw orchid

Crab claw orchid needs artificial pollination before it can bear fruit. Indoor pot sowing is often used, and the optimum temperature for germination is 22-24 ℃. The sowing medium is a mixture of peat, rotten leaf soil and coarse sand, and needs high temperature disinfection before sowing. Cover the basin mouth with glass after sowing in order to maintain the humidity of the basin soil, germinate 5-9 days after sowing, and the seedlings grow slowly, so it should be managed carefully.

Grafting propagation 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. In the south, mid-May is the most suitable, when crab claw orchid and cactus are in the peak growing season, and ideal scions and rootstocks can be selected. In addition, the temperature is suitable at this time, the affinity of scion and rootstock is strong, it is not easy to rot, and the survival rate is relatively high.

2. Rootstock selection: the one-year growing strip type, not too thick but vigorous, disease-free cactus branch was selected as the rootstock, and the length was between 8cm and 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.

3. Scion selection: the strong mother plant of crab claw orchid was selected for grafting scion, from which the tender top branch with nodes was selected as scion with a length of 3 cm to 4 cm (the scion grew weakly after sprouting). Cut the lower sides of the scion into a wedge with an alcohol sterilized blade, with a cutting length of about 0.8-1.2 cm.

4. Grafting method: first, the two sides of the basal segment of the scion are obliquely cut into a duckbill shape. The length of the cutting surface is 1.5 to 2.5 centimeters, which can be cut with one knife as far as possible to facilitate survival. Then cut longitudinally at the top of the rootstock, the width and depth of the knife is a little larger than the cutting surface of the scion, and the cut scion is quickly inserted into the cut of the rootstock and fixed. Finally, the connected flowerpot is placed in a cool and ventilated place from the wind and rain, and it is expected to survive in about 20 to 30 days.
