Planting of yuweng

Sowing time

April June of each year

Germination conditions

The suitable temperature for germination is 15-25 ℃

Specific method

Sprinkle the seeds of yuweng directly in the basin soil and germinate after 7 days. When the seedlings are planted separately after a long period of time, the seedlings can be planted separately in the pot

Precautions

Watering should be appropriate and the soil should not be too dry. The temperature of seedlings in winter should be above 10 ℃. When there are burrs on the top of the seedlings, they can be potted, one seedling in one pot. It is best to plant separately in spring

Cuttage of yuweng

Cutting time

Cutting can be carried out from April to October every year

Cutting conditions

The matrix of cutting is river sand and a small amount of saw. Plump and protruding pellets should be selected as cuttings. The ball is too small to rot

Specific method

Ensure that the spherical surface of the cuttings is smooth, then coat it with wood carbon powder or sulfur powder and put it in the shade for 2-3 days. When the secreted juice is dry, the cutting can be cut after the section shrinks. After planting, put it in the semi shade, spray some water to keep the soil moist, and take root and survive in about 40 days

Precautions

Cutting is not allowed in summer when it is hot and rainy, but cutting can be carried out all year round in the greenhouse. Cutting should not be too deep, and the incision should be slightly buried

Grafting of yuweng

Grafting preparation

Cactus or ruler is used for cutting board, and seed ball is used for scion

Specific method

The cactus cultivated for more than 3 months was grafted on a soft measuring ruler to promote its growth. When the scion grows to a certain size and cannot be supported by the cutting board, it can be cut off, dried and then cut and potted. Under the good environment of fertile soil and air circulation, the seedlings without grafting grow quickly. The seedling or grafted young ball after being put into the pot should be placed in the semi shade, and avoid direct sunlight. After 7-10 days, the ball will not shrink and can survive

Precautions

Do not water after grafting, but put it in a cool place
