How to grow red prince brocade flowers? Breeding and pest control and cultivation techniques of red prince brocade flower

According to the editor, the Red Prince brocade flower is introduced in the United States, flowering in May-June, generally suitable for planting in the courtyard or roadside, is a kind of flowers with high ornamental value, so what are its planting methods? How to prevent pests? Those who love flowers and plants can learn from the editor.

A detailed introduction of the breeding and pest control and cultivation techniques of the red prince brocade flower:

Selection of ear picking nursery and nursery bed

Loose, fertile, slightly acidic, neutral and slightly alkaline soils were selected to build ear harvest nursery and hedgerow nursery. If the soil is clay or lack of fertility, it is necessary to improve the soil, apply sufficient base fertilizer, apply rotten organic fertilizer 3000kg per mu, plus phosphate fertilizer 50kg. In order to prevent underground pests, the insecticide 2kg was applied per mu.

Ploughing to make a bed

The first ploughing should be deep ploughing, the depth is above 25cm, and then fine rake once. Ploughing for the second time to smooth the bed. The edge ditch is opened around the field, with a depth of 50 ~ 80cm and a width of 60cm. The middle trench is opened in the middle of the field, which is connected with the edge ditch, with a depth of 40 60cm and a width of 50 60cm. To make a bed, the width of the bed is 110cm, the soil on the bed is fine, the center of the bed is slightly higher, and the two sides are slightly lower. The trail between each seedbed is deep 25cm and wide 40cm. The ditches are connected and the drainage is smooth.

Ground planting

The planting time of ear nursery and hedgerow seedlings is from October to April of the following year. Plant spacing 35cm, row spacing 40cm, seedbed width 110cm, transversely planted 3 plants per mu, 3000 plants per mu. Before transplanting, the aboveground part should be trimmed, the height 15cm should be retained, and the cut branches should be used as panicle strips. The cuttings should be transported to the head of the field to avoid direct sunlight, not to be stacked, and to be planted in time. The planting depth is moderate and the rhizosphere of the original plant is slightly deeper than that of the original plant by digging holes at a fixed point according to the row distance. Then cover the base of the seedling with fine soil and press it gently.

Administration and Management

Water the fixed root thoroughly on the same day after transplanting. If there is a continuous sunny day, it should be watered on the 4th day after transplanting, and then watered every 10 days or so; in case of rainy days, it should be drained in time. Carry out full light management to promote Lignification. Apply enough base fertilizer before planting. From 15 days after planting, urea was applied to 5 kg/ mu every 10 days or so. Urea was applied in April, compound fertilizer was applied in May ~ June, less nitrogen fertilizer, more phosphorus and potassium fertilizer were applied in July ~ August, 0.2% urea was applied every 10 days in September, rotten organic fertilizer was applied in 10 ~ 12 months, and shallow ditches were opened and buried among plants. Combined with fertilization, loosening the soil and weeding, there are basically no weeds on the seedling bed. Loosen the soil in time on sunny days after rain to prevent soil surface hardening.

Disease prevention and cure

The common leaf blight is caused by Phaeocosporium, which harms leaves and branches, and the disease spot is yellowish brown, which leads to the death of the whole plant. Prevention and control methods: strengthen management and increase the application of rotten organic fertilizer. Enhance the tree potential and improve disease resistance. Remove diseased branches and leaves and burn them centrally. Spray 50% at the initial stage of the disease to make 500 times of 100 grams, 500 times of 75% chlorothalonil or 600 times of 80% zinc, once a week for 2-3 times. The young and rejuvenated female parent plants were easy to aging and the spike vigor became weaker after repeated panicle cutting. In order to enhance the vigor of panicle strips, more than 6-year-old female parents must take rejuvenation measures. In February of the same year, 15cm was cut flat at the height of the female parent above the ground, and then the soil was loosened, fertilized and cultivated in time to promote the germination of adventitious buds.

Cuttage propagation

Ear harvesting

In the first ten days of September, the semi-lignified branches of the same year were cut to retain the height of the female parent. The 1-year-old female parent retains 15 cm 25cm in 2 years old, 20 cm in 2 years old and about 15 cm in 3 ~ 5 years old. The panicle length is 4cm, keeping 2 leaves and keeping the crown shape of the female parent flat. The key to ear harvesting is the preservation of ear strips, which should be carried out in the morning or evening. The cut branches are covered with soaked non-woven cloth and sprinkled to keep them fresh. It is necessary to cool and moisturize during transportation. After arriving at the destination, put it indoors, spread the spray as soon as possible, and cut it in time.

Root accelerant for spike plants

Use "Sensheng No. 1" plant root accelerant 1g, dissolve it with 30ml alcohol for 30 minutes, then 600ml with water, and dip it in it for 2 seconds before cutting.

The matrix formula vermiculite ∶ peat ∶ perlite = 4 ∶ 5 ∶ 1, dry bulk density 0.20, total porosity 87.05%, macroporosity 26.05%, small porosity 61.00%, maximum water holding capacity 4.15. PH 6.87, EC value 0.85mS/cm, total nitrogen 0.90%, total phosphorus 526.24mg/kg, total potassium 5632.47mg/kg, calcium 1845.25mg/kg, magnesium 2456.25mg/kg.

Cuttage seedling bed cutting

The width of the ground seedling bed is 100cm, the footpath is wide 40cm, and the depth is 25cm. The elevated seedbed is wide 168cm and high 80cm. Cover the bed with floor cloth, then fill the substrate with 8cm, disinfect it with 600x solution of potassium permanganate and cover it with film for 24 hours. Cuttage depth 2cm, upright cuttage, immediately watering after cutting, immediately spraying 600x liquid carbendazim to disinfect and prevent disease after the foliar water evaporated. Then set up a small arch shed, cover it with a thin film, seal it around, and keep the air relative humidity in the shed above 95%.

Administration and Management

Before cutting, a sunshade net was set up above the seedbed, covering 1 layer in May ~ June and 2 layers in July ~ August. The sunshade net can be removed completely when the daily maximum temperature is below 30 ℃, and the whole light management can be done. A rod thermometer is hung in the small arch shed, and spray cooling measures should be taken when the air temperature in the small arch shed is above 36 ℃. Especially in sunny days and high temperatures, from 10:00 to 4 p.m., spray once every half an hour, so that the temperature drops below 36 ℃. Often check the humidity of the matrix to see dry and wet. Water once every 7 days or so in the evening or early morning. After cutting for 30 days, more than 90% of the panicles take root, and the seedlings can be refined. Choose to remove the film in the evening, ventilate both ends for 2 days, and then remove all of them. After the film is removed, full light management is implemented. Timely watering and spraying foliar fertilizer. From December to January of the following year, only timely watering is needed to maintain the humidity of the substrate. Water every 10 days from February, and spray foliar fertilizer at the same time. Seedling time: cuttage in early September, defoliation immediately after rooting, excluding dormant period (deciduous period), cultivation time 4 months, seedling height above 8cm, yield 90%.

Red Prince brocade flower is a very good green flowers and plants, not only flowering long flowers, but also very beautiful, is a good greening effect of plants, like relatives can collect Xiaobian finishing methods yo!

Cymes born in leaf axils or branches, Corolla funnel-shaped bell-shaped, bright red, luxuriant flowers, gorgeous and eye-catching. Red Prince brocade is a deciduous open shrub, belonging to the family Ninjuriaceae, with a height of 1 to 2 meters [1]. The leaves are oval, the twigs are light red (green in Hangzhou), and the old branches are grayish brown. During the flowering period, the red prince brocade blossoms at the beginning of summer, with dense flowers, the Corolla rouge red and gorgeous and pleasing to the eye. The flowering period is from May to July (early April to early July to the south of the Yangtze River), and the inflorescence continues to continue in October. The ecological habits of the Red Prince brocade belt the Red Prince brocade belt is light-loving, cold-resistant and afraid of waterlogging. Like fertile, moist, well-drained soil. The Red Prince brocade belt is resistant to cold and drought, and is rated as an excellent variety for the Green Olympic Games. Water once or twice a month in spring. In early spring, the dry branches should be cut off before the red prince brocade branches germinate, and fertilizer should be applied properly to promote the healthy growth of new branches. When there is more rainfall in high temperature in summer, attention should be paid to drainage to prevent root rot. Winter does not need to be cold-proof, but before the beginning of winter, it is necessary to pour fertilizer and water once to improve its cold resistance. No fertilizing and watering will be carried out throughout the winter. The cultivation techniques of Red Prince brocade belt Red Prince brocade flower is light-loving, cold-resistant, drought-resistant, extensive in management and shade-tolerant, so it is suitable to grow in sandy soil and warm and sunny environment. When seedlings are transplanted in spring, they do not need to carry soil balls, but in summer and autumn, they need to carry soil balls. In early spring, dry branches or old and weak branches should be cut off before sprouting, and fertilizer should be applied properly to promote the healthy growth of new branches. Pay attention to pruning in summer during the period of exuberant growth. In the process of cultivation, it can not only be trimmed into a ball type, but also be cultivated into a solo type. Before the beginning of winter, fertilizer and water should be watered once to improve its cold resistance and promote flowers to bloom in the coming year. Water and fertilizer management Red Prince Jindai likes humid environment, so water management should be strengthened in cultivation. The first three water should be irrigated after planting, and then it can be irrigated once or twice a month depending on rainfall and soil moisture, and it is appropriate to keep most of the soil moisture. In addition to watering, foliar spray can also be used to replenish water, which can effectively improve the survival rate of seedlings. In the second year, the green water should be irrigated in time in early spring, and the flowering period should be from April to June. Watering can be properly controlled and can be watered once a month. The water content during the flowering period is too large, and it is easy to make the flowers wither prematurely, and the watering after anthesis can be carried out with reference to the first year of planting. The Red Prince Jindai likes fertilizer, some circle fertilizer can be used as base fertilizer when planting, nitrogen, phosphorus and potassium compound fertilizer should be applied after flowering, frozen water should be poured at the end of autumn, and some cow, horse manure or sesame sauce dregs fermented by rot should be applied at the end of autumn. Some urea can be applied after sprouting in the following spring, appropriate amount of phosphorus and potassium fertilizer can be applied after anthesis, and fertilizer can be stopped after autumn, and ring fertilizer can be applied in early winter. Pruning and plastic surgery of the Red Prince brocade belt is usually carried out in early spring. Its plant shape is generally shrub-shaped, with 5 to 7 branches per plant. Because its flowers bloom on the 2012 branches, it is not easy for the old branches to blossom, so attention should be paid to timely updating the flowering branches when pruning. In order to keep the plants ventilated and transparent, the branches that are too dense should also be thinned in time. In addition, for thin and weak branches, dry and withered branches, disease and insect branches should also be removed in time. If there is no need to leave seeds after flowering, the residual flowers should be removed in time so as not to affect growth and flowering in the coming year because of fruiting and consuming a lot of nutrients. The propagation method of the red prince brocade flower can be propagated by sowing, cutting, ramet or striping and other methods. Sowing, propagation and sowing are usually carried out indoor pot sowing in the middle and late April of spring, which is generally used to raise a large number of seedlings. The seeds of brocade flowers are small and not easy to harvest, so they should be harvested in time after the fruit is ripe in October and collected after threshing and air-drying. In the middle and late April of the following spring, the seeds were soaked in cold water for 2 to 3 hours, mixed with 2 to 3 times of sand, spread to the leeward to accelerate germination, and sowed 6 to 7 days later. Pour enough bottom water before sowing, seed and sand are sprinkled on the bed surface, cover soil about 0.5 cm, cover after sowing, to keep the soil moist, until the seedlings are removed. Cutting propagation cutting can be divided into hardwood cutting and semi-lignified cutting. When hardwood cutting, commonly used annual mature branches, cut into 15cm to 20cm cuttings for open-field cutting. Semi-lignified cuttings were carried out from June to July in summer. Cutting semi-lignified top branches as cuttings, rooting powder can be used to promote rooting. Cuttings can be carried out under the shade shed, in the greenhouse or on the full-light fog bed, and the cutter had better disinfect the soil with phoxim, which not only eliminates insect pests, but also has the effect of sterilization and disease prevention. Striping or ramet reproduction should be carried out before germination in early spring. Striping propagation is best carried out in the growing period of early and middle June, press the lower branches of the plant into the soil, and pay attention to the branches buried in the soil to cut the cortex with a knife, in order to produce callus and promote its rapid rooting, and wait until early spring germination in the next year. Transplanting can be carried out. Breeding points the red prince brocade flower is a horticultural variety of brocade flower, the plant is 1 to 2 meters high, the twigs are light red and the old branches are grayish brown. Flowering in early summer, dense flowers, Corolla rouge, gorgeous and pleasing to the eye, flowering for up to a month, from the beginning of May to the first and middle of June. Can be planted in the courtyard, park, lawn, can also be planted in roadsides, slopes and other places, very beautiful. It is widely cultivated in Northeast and North China. The red prince brocade flower can be propagated by cutting, sowing, dividing plants or pressing strips and other methods. Cutting propagation cutting can be divided into hardwood cutting and semi-lignified cutting. When hardwood cutting, commonly used annual mature branches, cut into 15 to 20 cm cuttings for open field cutting. Semi-lignified cuttings were carried out from June to July in summer, and the semi-lignified top branches were cut as cuttings, which were easy to survive. In order to improve the survival rate of cutting, it can be quickly dipped in 500 mg / L indolebutyric acid (or other rooting powder, follow the instructions when using) to promote rooting. Cuttings can be carried out under the shade shed, in the greenhouse or on the full-light fog bed, and the cutter had better disinfect the soil with phoxim, which not only eliminates insect pests, but also has the effect of sterilization and disease prevention. Sowing propagation is generally used to raise seedlings in large quantities. The seeds of brocade flowers are small and not easy to harvest, so they should be harvested in time after the fruit is ripe in October and will be collected after dehydration and air-drying. It was sown in the indoor pot in the middle and late April of the following spring. Soak the seeds in cold water for 2 to 3 hours, mix in 2 to 3 times of plain sand, spread them in the leeward to accelerate germination, and sow seeds 6 to 7 days later. Pour enough bottom water before sowing, sprinkle seeds and sand on the bed, cover about 0.5 cm of soil after sowing, and add mulch to keep the seedbed moist until the seedlings are removed. Striping or ramet propagation should be carried out before the plant germinates in early spring. It is best to press the lower branches of the plant into the soil during the growing period in the first and middle of June. Pay attention to cutting the cortex with a knife in order to produce callus and promote its rapid rooting. Wait until the sprouting in the early spring of the next year, cut off from the place that did not enter the soil before pressing, and then transplant. The disease control symptom of the red prince brocade belt harms the brocade branch, the disease spot on the branchlet is brown, the edge is not obvious, the upper black small grain spot, namely the pathogen conidium, the injured branch withered. Prevention and control methods ⒈ careful maintenance, increase the application of organic fertilizer, loose improvement of soil, timely drainage after rain, prevent moisture retention and prevent frost damage. The diseased branches were cut off during ⒉ pruning, and the diseased branches or spots were removed before the conidia were conidia, so as to reduce the source of infection. During the release period of conidia, ⒊ sprayed the overwintering fungus of branch blight by spraying Fumei arsenic: water = 2 and 1: 100 every semimonthly. In addition, it can also spray 40% carbendazim or 36% methyl thiophanate 500 times, 50% carbendazim wettable powder 800 times. The distribution area of the Red Prince brocade belt was introduced from the United States by Professor Yu Shuxun of the Botanical Garden of the Chinese Academy of Sciences in 1982 and is now planted in the Rose Garden of Beijing Botanical Garden. It is distributed in Jiangsu, Shandong, Zhejiang and other places in China. The garden use of the Red Prince brocade belt the Red Prince brocade belt has slender branches, beautiful leaves, colorful flowers, brilliant belt, suitable for planting in courtyards, residential areas or 30 to 50% clusters planted in lawns and roadsides. The red prince brocade belt has a certain resistance to hydrogen fluoride, so it can also be used as a greening and beautifying plant in the factory mining area. In the use of the Red Prince brocade as a garden seedling, it has dense branches and leaves and bright colors, and the flowering period can be as long as more than two months. it is the main early spring shrub in North China. It is suitable for group planting in the corner of courtyard wall and lakeside; it can also be used as flower hedge and cluster planting on the edge of trees and forests; embellished in rockery and sloping land.

Red Prince Ribbon

Red Prince brocade is a deciduous shrub of Lonicera, which has the characteristics of bright flowers and long flowering period. it is an important spring flowering shrub in North China and Northeast China.

Water and fertilizer management

The Red Prince Jindai likes the humid environment, so the management of water should be strengthened in cultivation. The first three water should be irrigated after planting, and then it can be irrigated once or twice a month depending on rainfall and soil moisture, and it is appropriate to keep most of the soil moisture. In addition to watering, foliar spray can also be used to replenish water, which can effectively improve the survival rate of seedlings. In the second year, the green water should be irrigated in time in early spring, and the flowering period should be from April to June. Watering can be properly controlled and can be watered once a month. The water content during the flowering period is too large, and it is easy to make the flowers wither prematurely, and the watering after anthesis can be carried out with reference to the first year of planting. Watering in the third and subsequent years can be carried out according to the second year method.

The Red Prince Jindai likes fertilizer, some circle fertilizer can be used as base fertilizer when planting, nitrogen, phosphorus and potassium compound fertilizer should be applied after flowering, frozen water should be poured at the end of autumn, and some cow, horse manure or sesame sauce dregs fermented by rot should be applied at the end of autumn. Some urea can be applied after sprouting in the following spring, appropriate amount of phosphorus and potassium fertilizer can be applied after anthesis, and fertilizer can be stopped after autumn, and ring fertilizer can be applied in early winter.

Pest control

The common pests of the red prince brocade belt are: diamondback moth, yellow-brown sky caterpillar, red moth and so on. If diamondback moth occurs, 20% diflubenzuron 10000 times can be sprayed at the initial stage of its larvae, and 1000 times 1.2% nicotine EC can be sprayed for control of older larvae; if yellow brown tentorium caterpillar occurs, 1000 times 1.2% nicotine EC can be sprayed during the larval dispersion period; if red diamondback moth occurs, 3000 times of 5% Baofu EC can be sprayed when it occurs seriously.

Branch blight is the most common disease in the red prince brocade belt, which is caused by the infection of half-known fungi. In daily maintenance, it is necessary to strengthen water and fertilizer management and ventilation management to improve plant growth. Spraying 60% Dysen zinc wettable granule solution, 75% chlorothalonil wettable granule 1000 times liquid or 70% methyl thiophanate wettable granule 1000 times liquid at the initial stage of the disease, spraying three or four times in a row can effectively control the disease.

Pruning and shaping

Red Prince brocade belt pruning is usually carried out in early spring. Its plant shape is generally shrub-shaped, with 5 to 7 branches per plant. Because its flowers bloom on the 2012 branches, it is not easy for the old branches to blossom, so attention should be paid to timely updating the flowering branches when pruning. In order to keep the plants ventilated and transparent, the branches that are too dense should also be thinned in time. In addition, for thin and weak branches, dry and withered branches, disease and insect branches should also be removed in time. If there is no need to leave seeds after flowering, the residual flowers should be removed in time so as not to affect growth and flowering in the coming year because of fruiting and consuming a lot of nutrients.

Reproduction method

The breeding methods of Red Prince brocade belt are: cutting, ramet, striping.

The cuttings are carried out from June to July, the cuttings are about 10 cm long, the upper part is cut flat, the lower part is cut into horseshoe shape, retaining two or three leaves. After dipped in ABT rooting agent, it was inserted into the sterilized fine river sand seedling bed with a row spacing of 10 cm × 10 cm. Immediately after insertion, pour water thoroughly, buckle the shed to moisturize, and set up a shade net, which can take root in about 25 days.

Ramet is generally carried out in late autumn or early spring, and the brocade belt with strong growth and more branches is selected for ramet. Before the ramet, the plant is watered once. After the plant is dug up, it is split with a sharp knife. The new plant should have more than 3 branches, and then plant them separately.

At the beginning of June, the lower part of the branches of the Red Prince brocade were burnt and pressed into the soil to keep the soil moist. It can be separated from the mother plant in the next spring and planted separately.
