This paper introduces the cultivation and management technology of honeysuckle, including garden selection, variety selection, planting, field management technology and pest control technology, for your reference when planting honeysuckle, hoping to help friends who plant honeysuckle.

First, the garden choice of honeysuckle

Honeysuckle is not very strict with soil, but in order to obtain high yield and high efficiency, it is necessary to choose a plot with flat terrain, sufficient sunshine, fertile soil, convenient irrigation and drainage and pollution-free.

Sandy loam is beneficial to the accumulation of nutrients in honeysuckle because of its large temperature difference between day and night and strong drainage and ventilation. It is suitable to choose sandy loam when conditions permit.

Second, the choice of honeysuckle planting varieties

The excellent varieties cultivated in production mainly include Fengqiu Damaohua and Shandong Jizhaohua. In recent years, the new strain of Damaohua has stronger adaptability and more obvious high-yield traits, and is widely planted in Henan Province.

Fengqiu Damaohua is a national protected variety of origin, with upright tree shape, thick branches and easy pruning. Chlorogenic acid content is 5.6%-6.7%, which is resistant to pests and diseases and has strong adaptability. It is the first choice in production.

Third, the fertilizer and water management methods of honeysuckle

Fertilization is mainly organic fertilizer, with a small amount of compound fertilizer. The amount of fertilizer can be determined according to the size of the tree, with 5-6 kg of organic fertilizer and 50-100g of compound fertilizer per plant, and the seedlings can be reduced appropriately; Fertilization can be applied in furrow or radial furrow, and the fertilization depth is 20-30cm.

If there is drought during germination and flowering, it will affect the quantity and quality of flowers, so water them in time. Generally, the 40-60cm soil layer should be fully saturated with water during irrigation; Gardens with high groundwater level should pay special attention to drainage.

Fourth, the pruning method of honeysuckle is winter pruning, from 65438+February in winter to late February of the following year before germination; Pruning in summer, usually after the first crop of flowers, pruning spring shoots in early June; Pruning summer shoots in late July; Prune the autumn shoots in early September.

The standard of pruning is that the outer ring is empty, the middle is high and the periphery is low, showing an umbrella shape. For newly planted trees, cutting is the main pruning method. Generally, from the seedling stage, strong stems are selected and twigs, weak branches, diseased branches and overlapping branches are cut off.

For plants planted for the first time, the trunk height should be 15-20cm, 4-5 trunks should be selected, and the rest branches should be cut to about 15cm. After 3-5 years of pruning, the trunk is 30-40 cm high, forming a thick shrub-like trunk, making the flower pier umbrella-like, with good ventilation and light transmission.

Verb (abbreviation of verb) honeysuckle pest control The main disease that harms the newly-built gold and silver garden is powdery mildew, which usually occurs frequently in spring. Preventive measures: When sprouting in spring, spray 3 waves of meishi sulfur mixture or 600-800 times of 50% thiophanate-methyl wettable powder for foliar spraying.

The main pests in the newly-built gold and silver garden are aphids and cotton bollworms;

When aphids are rampant, spray 2000 times of 10% imidacloprid wettable powder or 3000 times of 1.8% avermectin EC. Generally, it can be controlled once and twice every 7- 10 day.

From June to September, the disease of cotton bollworm is serious, and the control method: spray Bacillus thuringiensis emulsion 400-500 times at the peak of egg incubation, once every two days, usually three times.
