I. Planting techniques
1, land selection and land preparation
When planting honeysuckle, we should choose sandy loam with gentle slope, open and flat, deep soil layer, fertile and loose, good ventilation and drainage. Before planting, 2000 kg of fully decomposed organic fertilizer and 30 kg of ternary compound fertilizer were applied to each mu of land, and after ploughing and harrowing, the low or high border with a width of 1.2 m could be made.
2. Planting method
There are two ways to grow honeysuckle, one is sowing and the other is cutting. This paper mainly introduces the seed sowing technology. Generally, in April, the seeds are soaked in warm water at 35℃~40℃ for 24 hours, and then wrapped with wet sand to accelerate germination.
3. Transplanting and planting
The time is from dormancy in autumn and winter to germination in early spring. After transplanting, intertillage should be used to weed 3~4 times a year, but shallow tillage should be used around the rhizosphere.
4. Loosening and fertilizing
Loosening honeysuckle will be carried out around the end of March. When loosening the soil, you can turn over 10 cm to cut off some old roots. After loosening the soil, fertilize honeysuckle, such as plant ash urea, potassium sulfate, human and animal manure, etc., to promote its growth.
Second, cultivation management.
1, young tree pruning
Pruning of young honeysuckle trees. Planting in 1-2 mainly focuses on shaping. After the new branches germinate in spring, thick branches can be selected as the trunk. When the trunk grows to 25 cm, it will be cored to promote the development of lateral branches. After germination, the lower branches of the lateral branches will be removed, making the trunk thicker year by year.
2, pest control
The main pests and diseases of honeysuckle are aphids, cotton bollworms, bean moths and anthracnose. Anthracnose of honeysuckle mostly occurs in rainy season, and carbendazim or thiophanate-methyl can be sprayed once every seven days for three times. When picking honeysuckle, it is best to pick it without dew, and then air-dry it naturally or manually.
Control of honeysuckle pests and diseases
1, brown spot disease
Common diseases on leaves make plants weak. Most cases occur in the small late growth period, and the peak period is August-September, and the disease is more serious under rainy and humid conditions. At the beginning of the disease, brown spots are formed on the leaves, and then they expand into brown round spots or irregular spots. There are gray-black mildew spots on the back of the diseased spots, which can make the leaves fall off when the condition is serious.
Control method: cut off diseased leaves, then spray with 1: 1.5: 200 bordeaux solution, and spray 1 time every 7 ~ 10 days for 2 ~ 3 times; Or use 500 times dilution of 65% zineb or 1000 ~ 65438+.
2. Powdery mildew
Suffering from serious illness in warm and dry conditions or in the shade of plants; Excessive nitrogen application, dense plants and serious diseases. At the beginning of the disease, white spots appeared on the leaves, and then gradually expanded into white powder spots, which continued to spread all over the leaves, causing the leaves to turn yellow, shrink and deform, and finally causing falling flowers, leaves and dry branches.
Prevention and control methods: clearing the garden to treat sick and disabled plants; 50% thiophanate 1000 times solution or BO- 10 biological spray was used in the occurrence period.
3, aphid harm
Leaves and shoots cause leaves and buds to curl, stop growing, and the yield drops sharply. Insect pests are serious from April to June, and spread quickly around the "long summer", especially in rainy days.
Prevention and control methods: spray with 40% dimethoate 1000 ~ 1500 times diluent or yusong 1000 ~ 1500 times diluent to kill for several times continuously until killing.
4, inchworm head
After the stubble blooms, the larvae gnaw at the leaves, resulting in reduced production.
Control method: After entering spring, dig out the soil around the plant within the range of 1 m and kill the pupae. Spraying 2.5% pirocin EC for 400 ~ 600 times at the initial stage of larval occurrence; Or spray dichlorvos and trichlorfon. , but stopped spraying at flowering stage.
