Honeysuckle Economic Value and Breeding and Cultivation Techniques

Lonicera japonica Thunb is a perennial semi-evergreen vine of the family Lonicera, also known as Lonicera. The rattan grows up to 8-9 meters in length and has hollow stems. Leaves opposite, entire, ovate. Flowers paired to leaf axils, pedicellate, bracteate leaflike; corolla lipbone, upper lip 4-lobed erect, lower lip reversed; flowers open white at first, then gradually become golden yellow, flowering on same vine The flowers of different flowering ages matched each other and were named "Honeysuckle". The flowering period was from May to July. Berry spherical, mature black, fruiting period from August to October, each fruit has 4-7 seeds, the seed grain weight is 3-5 grams.

Honeysuckle has strong cold resistance and heat resistance, hi light, but also can shade, strong drought resistance, soil requirements are not strict, can grow in the slightly acidic or alkaline soil. Therefore, it is widely distributed in China, starting from Jilin and Liaoning in the north, Shaanxi to the west, and Fujian to the south, and is distributed on hillsides and wastelands 200 to 1000 meters above sea level.

First, economic value

Medicinal use

The buds of honeysuckle contain effective medicinal ingredients such as flavonoids, inositol, saponins, tannins, and chlorogenic acid. Fresh vines and leaves contain tannins and flavonoids. These effective medicinal ingredients enable honeysuckle to have detoxification and Broad-spectrum antibacterial effect, in the clinical treatment of tonsillitis, pharyngitis and pneumonia and other respiratory diseases and dysentery, sore and so on.

2. Health care

Honeysuckle flower buds and stems and leaves contain a variety of amino acids (total content of 8%), carbohydrates (more than 18%) and 8 essential trace elements (iron, zinc, manganese, chromium, copper, nickel, cobalt, Silicon) has a high nutritional value and strengthens the role of body defensive muscle energy. At the same time, it has been widely used in the production of various health products such as honeysuckle tea and honeysuckle because it has effective medicinal ingredients such as antibacterial and antivirus. Wine, drinks, candy, toothpaste, etc.

3. Ornamental and Soil Conservation

Honeysuckle has a long flowering period, yellow and white when the flowers bloom, aromatic and pleasant, vines winding, prosperous, is a good material for vertical greening and landscaping in gardens, suitable for decorative sheds, rockery and so on. In addition, after the pruning, the stems and stems can also be used as stump bonsai.

The roots of honeysuckle are well developed and have many roots. According to the investigation, the depth of the roots along the rock joints in the mountain can reach more than 9 meters, and it can extend to more than 12 meters in all directions; its stem and leaf density is large, and the canopy cover ability is strong, with strong slope protection. Solid soil, water retention and water holding capacity are excellent soil and water conservation plants.

Second, reproductive technology

1. Seed propagation

During August-October, fully ripened fruit is harvested from robustly growing, disease-free plants or shoots. After harvest, the fruit is rinsed, the skin and flesh are rinsed with water, dried and mixed, and the resulting pure seeds are at 0-5°C. The lower layer is sown till March-April. Before sowing, the seeds are soaked in warm water of 25-35°C for 24 hours, and then mixed with wet sand at room temperature for germination. When 30%-40% of the seeds are cracked, they can be planted. Seedlings when planting 100 grams per square meter is appropriate.

2. Cut propagation

The cutting method can effectively reproduce honeysuckle. Cuttings can be carried out in spring, summer and autumn, with the highest survival rate in the rainy season. For cuttings, take 1 year of strong shoots (or post-flowering branches) for cuttings, leaving 3-4 pairs of shoots (or leaves) on each cutting, remove the lower leaves, and insert them on the seedbed. 50-100 mg/kg NAA can also be used as a rooting agent to promote rooting of the cuttings. After the cuttings, it is necessary to pay attention to frequent spraying, and rooting can be performed within 2-3 weeks after inserting. The spring planting seedlings can be transplanted in the fall, and the summer and autumn seedlings can be transplanted in the spring of the following year.

3. Pinching

During June-October, we used the bottom of a rich nutrient-rich wet mud to take the post-harvest flowering branches of the year and press them with the above-mentioned fertilizer to make it 2-3 times. Cover it with some grass to moisturize it. After 2-3 months at the festival, The adventitious roots were born, and then the branches were cut off at 1 cm after the node of the adventitious roots, allowed to separate from the mother plant and grown independently, and later planted separately.

4. Breeding

It can be done in early spring or late autumn. Since the ramets will inhibit the growth of the mother plant to a certain extent, they should only be used when the wild cultivars are expanded in small amounts.

Third, cultivation management points

1. Cultivating, weeding and earthing

After the seedlings of the honeysuckle seedlings or asexually propagated seedlings are planted, cultivators and weeds are to be timely and timely cultivated during the annual growing season. When planting in a cold area in winter, the loose soil shall be used to bind the soil to the rhizosphere in order to prevent the root system from being frozen.

2. Fertilization, drainage and irrigation

In the early spring or late autumn, the combination of cooked manure and superphosphate is applied. Fertilization can be used when the ring fertilization method: that is, around the plant to open a ring ditch, apply fertilizer into the earth after filling. In addition, when flower bud differentiation is seen before flowering, foliar assisted spraying of ammonium dihydrogen phosphate (NH4H2PO4) is performed. Where conditions permit, early spring or flowering should be properly irrigated in case of drought, and when there is too much rain in the rainy season, drainage should be promptly performed to prevent water from falling or buds from breaking.

3. Pruning

The natural regeneration ability of honeysuckle is good, and the branching is more. The plastic trimming is beneficial for cultivating the thick main trunk and the main branch, making the branches stand upright and has good ventilation and light transmission, which is favorable for increasing the yield and enhancing the disease resistance. Plastic surgery is when the plant is about 30 centimeters after planting, cut the top tip, remove the apical dominance, and promote the sprouting of lateral buds. Among the axillary lateral buds, 4-5 robust branches were selected as the main branch, and the rest were cut off. After the first branch of the main branch grows, retain 6-7 pairs of buds and cut off the top; then retain 6-7 pairs of buds from the secondary branch that grow on the first side branch and cut off the top. After the above-mentioned stepwise shaping, the honeysuckle plants can stand upright, have branches and layers, and have good ventilation and light transmission.

In addition to plastic surgery, it is necessary to adjust the plants in combination with pruning measures in winter and growing seasons when growing honeysuckle. Winter shears cut the diseased branches, weak branches, and dead branches after the annual frost fall until the freezing; the pruning of the growing season is cutting the top of the branches after flowering, prompting the flowering mother branches to draw new branches early and open the second flower. Because the flower bud differentiation of honeysuckle is performed only on newly-picked shoots, even though the flower-bearing shoots can continue to grow, they can not be re-knotted, and only the new shoots on the mother branch of the original flower-bud can form flower buds.

4. Pest control

Honeysuckle pests and diseases mainly have honeysuckle brown spot, damage leaves, from July to August onset. After the onset of disease, the lesions on the leaves were rounded or limited by the veins and were polygonal, yellow-brown, with gray moldy leaves on the back when wet. Effective prevention and control methods are timely removal of diseased branches and diseased leaves, strengthening of cultivation and management, and application of organic fertilizers to enhance disease resistance. In addition, spraying Bordeaux 1:1.5:200 in the early stage of the disease can effectively control brown spot.

The main pests of honeysuckle are locusts and coffee tigers. The control of aphids can be prevented and sprayed with 40% Dimethoate EC 1000-1500. The prevention and treatment of coffee tiger Tianni can be used to destroy the litter to destroy the growth environment of its eggs; or July-April artificial release of natural enemies law, coffee tiger Tianniu natural enemies have red belly and swollen legs bee, the appropriate release density of 1500 Head / hm2, control effect is obvious; can also be used sweet and sour venom (1 sugar: 5 vinegar: 4 water: 0.01 trichlorfon) for sedation.
