The latest method of cultivation of broccoli

The brocade belt flower is also known as the five-color begonia, mountain fat hemp, sea immortal flower and so on. It is a deciduous shrub of the honeysuckle family, with dense branches and leaves and colorful flowers, and the flowering period can be as long as more than a month. It is suitable for group planting in the corner of the courtyard wall and by the lake. It can also be planted in the edge of the forest for hedgerow and cluster planting, embellished in rockery and sloping land. Let's take a look at the breeding method of brocade flower.

The growth habit of Brocade

Brocade flowers are distributed in Heilongjiang, Jilin, Liaoning, Inner Mongolia, Shanxi, Shaanxi, Henan, northern Shandong, northern Jiangsu and other places in China. They are born under the mixed forest or in the bushes at the top of the mountain at an altitude of 100m to 1450m. Like light, shade tolerance, cold resistance, lax requirements on the soil, can withstand barren soil, but to deep, moist and humus-rich soil growth is the best, afraid of waterlogging. Strong sprouting ability and rapid growth.

The Propagation method of Brocade

1. Sowing: the seeds can be collected from September to October, soaked in cold water for 2-3 hours in direct seeding or one week before sowing. Sowing in no wind and no rainstorm weather in the near future, the bed should be flat and fine. The sowing method can be bed sowing or strip sowing, the sowing amount is 2 grams / square meter, the thickness of covering soil after sowing can not exceed 0.3 cm, keep the bed moist within 30 days after sowing, and emerge seedlings about 20 days.

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

3. Striping: the brocade flower can be pressed into the soil for strip reproduction in the growing season, and the lower branch is usually selected after flowering. The lower branch is easy to be creeping, and the node is easy to take root and survive.

4. Ramet: 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 culture method of Brocade flower

1. Fertilization: when brocade flowers are planted in pots, 3 parts of garden soil and 1 part of rice chaff ash can be mixed, plus a small amount of barnyard manure as base fertilizer. Rotten compost was used as base fertilizer when planting, and then ditched in the root every 2 to 3 years during the dormant period in winter or early spring. Fertilize once or twice a month during the growing season.

2. Watering: pay attention to watering the brocade flowers during the growing season. After sprouting in spring, the amount of water should be gradually increased to keep the soil moist. High temperature and drought in summer are easy to make leaves yellow, dry and withered, so it is necessary to maintain sufficient water and spray water to cool 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. Pruning: the growth period of brocade flower is longer, and the top branchlets are often not full before winter, and are easy to dry up when overwintering. Therefore, the dry and withered branches at the top of the plant and other old and weak branches, disease and insect branches should be cut off and cut short and long branches before sprouting in spring every year. If there is no seed, the residual flower branches should be cut off in time after flowering, so as not to consume too much nutrients and affect the growth. Branches that have been growing for 3 years should be cut off from the base to promote the robust growth of new branches.

4. Diseases and insect pests: there are not many diseases and insect pests in brocade flowers, occasionally harmed by aphids and red spiders, which can be sprayed with dimethoate.
