How to raise "five-color begonia" brocade flowers? How do you breed?

Brocade is a deciduous shrub of the genus Ninjuriaceae, which can bloom for more than a month. It is suitable for planting in the corner of the courtyard wall and by the lake. It can also be planted in hedgerows and clumps on the edge of the forest, embellished in rockery and slopes. How to raise the brocade flower of "five-color begonia"? How do you breed?

I. the growth habits of brocade flowers.

Brocade is distributed in Heilongjiang, Jilin, Liaoning, Inner Mongolia, Shanxi, Shaanxi, Henan, northern Shandong, northern Jiangsu and other places in China. It is born under the mixed forest or in the shrub on the top of the mountain at an altitude of 100,1450 meters. It likes light, is shade-tolerant, cold-tolerant, and can tolerate barren soil, but it grows best in deep, moist and humus-rich soil, which is afraid of waterlogging, strong sprouting ability and rapid growth.

Second, the culture method of brocade flower

1. Timely fertilization

When planting brocade flowers in pots, 3 parts of garden soil and 1 part of rice chaff ash can be mixed, and a small amount of barnyard manure can be used as base manure, and mature compost should be used as base manure when planting, and then once every 2 to 3 years in winter or early spring dormancy period, fertilizing once or twice a month in the growing season.

two。 Pay attention to watering

Pay attention to watering in the growing season. After sprouting in spring, the amount of water should be gradually increased and the soil should be kept moist. High temperature and drought in summer can easily make leaves yellow, dry and wither, keep sufficient moisture and spray water to cool down or move to semi-shady and humid places for maintenance. Water should be watered once or twice a month to meet the growth needs.

3. Timely pruning

The growth period of Brocade is long, and the top branchlets are often not full before winter, and they are easy to dry up when overwintering. Therefore, the dry and withered branches at the top of the plant, other old and weak branches, disease and insect branches should be cut off before the spring germination every year, and the long branches should be cut short. If there are no seeds, the residual flower branches should be cut off in time after flowering, so as not to consume too much nutrients and affect the growth. For the branches that have grown for 3 years, they should be cut off from the base. To promote the robust growth of new branches.

4. Pest control

Brocade flower diseases and insect pests are not many, occasionally aphids and red spiders harm, can be sprayed with dimethoate.

3. Propagation methods of brocade flower

1. Sowing and reproduction

The seeds can be harvested from September to October, soaked in cold water for 2 to 3 hours, soaked in cold water for 2 to 3 hours before sowing, and sowed in the weather without wind or rainstorm in the near future. the bed should be flat and fine, and the sowing method can be sowed or sowed with 2 grams per square meter, the thickness of covering soil should not exceed 0.3cm, keep the bed moist within 30 days after sowing, and emerge about 20 days after sowing.

two。 Cuttage propagation

The variation type of brocade flower should be raised by cutting method, and it is difficult to maintain the character after seed propagation. The ground temperature is 25: 28 ℃, the air temperature is 20: 25 ℃, the air humidity in the greenhouse is 80%-90%, the transmittance is about 30%, and it can take root in 50-60 days, and the survival rate is about 80%.

3. Striping propagation

The brocade flower can be pressed into the soil for strip propagation in the growing season, and the lower branches are usually selected after flowering. The lower branches are easy to be creeping, and the nodes are easy to take root and survive.

4. Ramet propagation

The ramet propagation of Brocade is usually carried out in early spring and autumn and winter, and is usually carried out in combination with transplanting before and after germination in spring. The whole plant is dug up, divided into several clusters and planted separately.

The above is the introduction of the breeding methods and breeding methods of brocade flower by Tuliu. it is suitable for group planting in the corner of courtyard wall and lakeside, and it can also be used as fence and cluster planting on the edge of forest, embellished in rockery and sloping land. Brocade flower has strong resistance to hydrogen chloride and is a good anti-pollution tree species, and flower branches can be placed in bottles.
