The Cuttage Propagation technique of Mulberry Flower

Fusang flowers are deeply loved by everyone. If there are some walls in the house, or even a corner that is not very beautiful, you can plant a mulberry flower. He is growing so fast that he can make up the corner right away. And his roots won't hurt the wall base. But you can't plant it too close to the window, because it grows so fast that it may block out all the views in the garden.

Fusang is a strong positive tree species that likes sunlight very much, and it does not need to be masked in summer, so it is very suitable for courtyard balcony cultivation. It also likes the moist environment with plenty of water, especially the high humidity in the air, the rapid growth and the stretching of the leaves, so we should pay attention to the foliar spray during the growing period. It is not strict with the soil; it grows luxuriantly in fertile and well-drained loam.

Fusang is mainly propagated by cuttings. The period of cutting is usually combined with pruning in early spring. Indoor cuttings are from March to April, and outdoor cuttings are available after late April. Cuttings root matter, to choose drainage, ventilation performance of good materials, generally can use pure sand or vermiculite. Use pure sand to sift out silt, rinse with clean water several times and then wash and disinfect with boiling water.

Cutting can be carried out except in winter, but the survival rate is high in Meiyu season. The best cuttings are one-and-a-half lignified cuttings, which are 10 cm long, leave top leaves, cut flat, insert sand beds, and take root about 3 weeks after insertion. Grafting is mostly used for double flower varieties with difficulties in cutting, branch grafting or bud grafting, and rootstocks are supported by single-petal flowers.

The survival rate of spring planting is higher than that of autumn planting, and the survival rate of ground planting is higher than that of pot planting, and the survival rate is faster, so it can blossom in the same year. In general, it is appropriate to choose biennial strong branches, or use current year semi-lignified strong branches, preferably cut into cuttings of about 15 cm in length in the middle of lateral branches, with 5 Mel and 7 nodes. Insert bed soil with good drainage, strong ventilation of coarse sand or silica, after disinfection, and then insert the bed, about 15 Mel 20 cm thick. The lower leaves of cuttings should be flattened with a sharp knife and cut in time, with a depth of 1 to 2. Immediately after insertion, pour water once, cover it with plastic film, maintain proper temperature and humidity, keep it moist but not wet, drain well, and then gradually accept sunlight to maintain an air temperature of 18 ℃ and a relative humidity of 70% to 80%. It can generally take root after 20 days, and it can be put on the basin in about a month.

The survival rate of cuttings with semi-Lignification is the highest, and those that have been naturalized can also be used. The cuttings can be cut and grow by about 10 centimeters, and the cut is in the lower part of the section, which is required to be smooth and smooth. The cuttings keep the top 2 leaves and remove the rest. The rootstock is inserted at an interval of 5 cm, and the depth is about 1 inch 3 of the total length of the cuttings. Immediately after insertion, it was watered thoroughly and kept for about 20 ℃. It could take root in about 1 month.

Cutting propagation requires an environment with high air humidity, so water should be sprayed once a day before noon and in the evening. If the cuttage is in the basin, the pot can be covered with plastic bags and sprayed with water every 2 days. Those who are cut before April need not be shaded, but those who are cut after May should be shaded around noon, in addition to increasing the number of times of spraying water to maintain humidity.

Cuttings are often used in production, such as greenhouse cuttings and outdoor cuttings. Outdoor cultivation, cutting from May to June in early spring, one-year-old and half-woody branches were selected for cuttings, and the length of cuttings was 8-l0cm. Except for the lower leaves, the upper leaves could be cut off by half, watered and watered after being inserted into coarse sand for 3 times, and the row spacing was 4cmx4cm. Keep the air temperature and cover it with film. Most of them take root after 20 days and can be put on the pot after growing for more than a month. Indoor cutting is generally in early spring January-February combined with pruning, cutting, sand as the substrate, the effect is better. In cold places, use heating, keep the temperature at 20-25 ℃, fill the basin with sand, insert it into the basin, spray water 1-3 times a day, take root in more than 40 days, take root in 60 days, and the survival rate is 60%.
