Planting technology and management of honeysuckle.
Honeysuckle has low requirements for soil, and sandy loam is the best, with a pH value of 5.5-7.0. Before planting, apply 2,000-3,000 kg of organic fertilizer per mu, plough deeply for 25-30cm, harrow, dig planting holes according to 1.5m row spacing and 1m plant spacing, and pour water. Honeysuckle is drought-tolerant and generally does not need watering after planting. The row spacing can be adjusted appropriately, which is beneficial to mechanical fertilization, intertillage, weeding and harvesting. In the management of honeysuckle, the labor cost is the most important cost that affects the income, so it should be fully considered when planting, so as to provide convenience for the mechanized operation of various management links such as pruning, fertilization and picking in the future, improve the mechanization level as much as possible and reduce the labor cost.

It is not recommended to use self-retaining seeds and cuttings to raise seedlings, which is time-consuming and laborious, and the quality and survival rate of seedlings are not easy to control. It is suggested to buy seedlings directly. According to the investment budget and planting plan, selecting 2-year-old or 3-year-old seedlings can greatly shorten the investment cycle and get quick results. Choose 3-year-old seedlings, you can pick a few flowers in the second year after planting, and enter the high-yield period in the third year.

The management of honeysuckle is mainly pruning and shaping, and the trunk is trimmed into a tree with a height of 30-40cm. It is based on the principle that winter pruning should be heavy, summer pruning should be light, short pruning should promote flowering and control crown width. Pruning time is generally combined with plastic surgery, from winter to the next spring before germination. In summer and autumn, cross branches, twining branches, overlapping branches, weak branches, long branches and dead branches should be cut off in time after each flowering, so as to ease the tree vigor and improve ventilation and light transmission conditions.

Adequate water and fertilizer is the key to high yield. After thawing in early spring, apply 25-30 kilograms of ternary compound fertilizer per mu, and cooperate with intertillage and ditching beside plants. Honeysuckle has developed root system and strong drought resistance. Huanghua city has abundant rainfall in summer and good soil moisture in winter, so it is generally unnecessary to water.

Honeysuckle has few pests and is vulnerable to aphids around May. Spraying 4000 times of 10% imidacloprid wettable powder can control it. The main diseases are brown spot and powdery mildew, which can be prevented by cultivation management, strengthening pruning, improving ventilation and light transmission conditions, and applying more organic fertilizer to enhance plant disease resistance. At the beginning of the disease, 70% mancozeb wettable powder can be sprayed with 800 times solution, and sprayed every 7 7- 10/day/time, 2-3 times in total. 10- 15d Do not use drugs before picking to avoid pesticide residues affecting the quality of honeysuckle.
