Cultivation and Management of Flos Lonicerae

Honeysuckle belongs to the semi-evergreen twining shrub of honeysuckle family. It blossoms as white as silver and yellow as gold on the same vine. After harvest, the yellow and white flowers can be mixed together with the same efficacy, so they are also known as "two flowers", "double flowers" and "double precious flowers". Its vines and leaves can also be used as medicine. Honeysuckle has strong adaptability, moisture resistance, drought resistance, cold resistance, before the house, behind the house, hillside can be planted.

Honeysuckle has the methods of cutting, striping, ramet and seed propagation, but the cutting method is the most simple and easy, with high survival rate and early flowering. The cuttage of honeysuckle should be in Rain Water season or after the Beginning of Autumn in spring. 2 ~ 3-year-old branches with strong growth and free of insect pests should be selected and cut into cuttings about 40cm. According to the plant spacing of 1.3m and row spacing of 1.3m, holes about the size of 30~50cm should be dug. Each pit is buried with 4 cuttings and 3 knots exposed on the soil surface, and the soil can be filled.

After honeysuckle cutting, it is necessary to strengthen management, especially the following four hurdles.

1. Ploughing, weeding and soil cultivation. Mid-tillage weeding can be divided into spring, summer and autumn, in which spring and autumn combine to cultivate soil.

two。 Fertilize. The first fertilization can be carried out after ploughing and weeding in early spring, with compost or mountain mud ash of 10 ~ 15kg per pit, and the second time after the first flower picking, with about 5kg of feces or appropriate amount of chemical fertilizer in each pit.

3. Prune. In early spring, the branches that are too dense or too old should be properly cut off, so that the branches are evenly distributed, and brackets should be set up to facilitate climbing, make them ventilated, transparent, and promote their flowering.

4. Control diseases and insect pests. The common diseases of honeysuckle are honeysuckle brown spot, anthracnose and rust, insect pests are aphids, longicorn beetles and so on. The control method of honeysuckle brown spot is pruning in winter and spring and keeping the plant ventilated and transparent. 50% benzimidazole 1000 × 2000 times liquid spray can be used at the initial stage of the disease, once every 7 days, even 2 times 3 times. Prevention and control of anthracnose and rust: strengthen field management, prune branches in time, apply more fertilizer, and promote plant growth. Aphid control methods: tobacco 0.5kg, add water 15~20kg, soak for 1 day and night, filter and spray, or spray with dimethoate emulsion 0.5kg and water 1000kg, aphid control must be carried out within half a month after flower picking. Control methods of longicorn beetles: before the Qingming Festival, when longicorn beetles are about to drill out of the soil, use dichlorvos to spray flower feet; when parasitic branches of longicorn beetles are found in summer and autumn, they can be cut off and burned or injected into wormholes.

How to prune honeysuckle

The pruning of honeysuckle is directly related to the yield. If it is well pruned, the general yield can be increased by 3040%, but at present, most drug farmers do not know how to prune. The pruning methods of honeysuckle are briefly introduced as follows:

First, the pruning of infancy: honeysuckle is young from planting to the fourth year. This period can be re-cut and renovated. According to the different planting place, it can be divided into umbrella method and natural shape method. ① cultivated in plain and hilly land, without stone as natural winding and without bracket, should be pruned by umbrella method. That is to say, the upper part of the branch of Flos Lonicerae was cut off at the height of 30cm to promote the rapid germination and growth of lateral buds. After that, the new branches growing downward were cut off every year, and the overlong steep branches were cut off according to the requirements of the umbrella crown. The honeysuckle cultivated by ② in the Shishan area is pruned according to the natural shape, that is, according to the shape of the stone pile, the terminal bud is cut off at the branch treaty 1/3, and then with the growth of the branches, combined with the shape of the stone pile, cut off or part of the branches that extend upward beyond the stone, at the same time, cut off the steep long branches and over-dense branches, so that they are evenly distributed on the stone pile.

Second, the pruning of the full flowering period: the flowering period of honeysuckle is about 15 years. The method of heavy shearing is adopted in this period. That is, heavy cutting of weak branches and dense branches; two-year branches, strong branches and light pruning. And implement the "four retention and four shears", that is, to keep the upper branches, buds on the back, thick buds and full buds; cut off the downward branches, downward buds, delicate branches and thin buds, and wipe off the sprouting buds at the base, so as to reduce the consumption of nutrients.

Third, pruning in the aging period: this period is characterized by sparse leaves, light color, many withered branches and thin flowers, and shrunken crowns. At this time, it is necessary to carry out full pruning of withered branches, heavy pruning of diseased branches, light pruning of weak branches and no pruning of strong branches.

The season of pruning honeysuckle depends on the growth period and method. The infancy, senescence, heavy shearing and light shearing are mostly in winter, late summer and early autumn, and the flowering period is mostly in late winter and early spring when new buds are not sprouting. No matter which method, pruning should be combined with weeding, fertilization, and replenishment of nutrients, so that honeysuckle can return to normal as soon as possible.
