Honeysuckle has strong adaptability, and the choice of soil and climate is not strict, and sandy loam with thick soil layer is the best. Hillsides, terraces, weirs, dams and barren hills can all be cultivated. Propagation can be achieved by sowing, cutting and rooting. Germinate and blossom on the new branches of the year. The requirements for soil are not strict, and both acid and saline-alkali land can grow. With developed root system and strong rooting ability, it is a good soil-fixing and water-retaining plant, which can be planted on hillsides and river banks. Therefore, the agricultural proverb says: "Waterlogged crops kill grass, and frozen pomegranate drying melons does not affect honeysuckle."

1. Seed propagation

Sowing in April, soaking the seeds in warm water at 35 ~ 40℃ for 24h, taking out 2 ~ 3 times of wet sand to accelerate germination, and sowing when the crack reaches about 30%. Sow in furrow according to the row spacing of 2 1 ~ 22 cm, cover with soil 1cm, and spray water 1 time every two days for more than 10 days. Transplanting in autumn or the following spring, using about 15kg of seeds per1hm ㎡.

2. Cutting

Usually in the rainy season. In rainy weather in summer and autumn, the robust 1 ~ 2-year-old branches are cut into 30 ~ 35 cm, and the lower leaves are used as cuttings. On the selected plot, according to the row spacing of 1.6m and the plant spacing of 1.5m, the depth is 16 ~ 18cm, and each hole has 5 ~ 6 cuttings, which stand obliquely in the buried soil in the form of dispersion, with 7 ~10.

Pay attention to shading before pruning to avoid dry branches caused by direct sunlight. Cutting can also be used to raise seedlings; In July and August, put the cuttings into the ditch, the row spacing is 23 ~ 26 cm, the depth is about 16cm, and the spacing is 2cm. Fill and compact the cuttings with soil. Using sandy soil with good air permeability and water permeability as seedling soil has the fastest rooting and is not easy to be invaded by germs and cause branch rot. Spraying water once after planting, and watering 1 time every two days after drought, which can take root in about half a month, and transplanting in spring or autumn the following year.

Step 3: plastic trimming

Pruning should be done after defoliation in autumn and before germination in spring. Generally, strong branches are lightly cut, weak branches are strongly cut, and all branches are cut. When pruning, pay attention to ventilation and light transmission after the new branches grow. All weak branches, withered old branches, basic branches, etc. It should be cut off, and the plots with poor fertilizer and water conditions should be trimmed heavier. Old branches should be cut off to promote the growth of new branches. Young plants are mainly cultivated plants and should be lightly cut. Generally, 4 ~ 5 trunk branches are left in mountainous areas, and 1 ~ 2 trunk branches are left in plains. The top of the trunk should be cut off to make it stout and upright.

Combination of shaping and pruning. In principle, it is based on fertilizer and water management, which can improve the whole, make full use of space, increase the amount of branches and leaves, make the plant type more reasonable, and obviously increase flowers and yield. The flowering time after pruning is relatively concentrated, which is convenient for harvesting and processing. Generally, branches can stand upright after pruning, and removing weak branches and basic branches is beneficial to the formation of new flowers. Pick the flowers and cut them. After cutting, apply quick-acting nitrogen fertilizer once and water once to promote the next crop to blossom ahead of time. In this way, you can collect flowers four times a year, and you can collect dried flowers 150 ~ 200 Jin on average every 667 square meters.

4. Tian Tuan management

Topdressing: During the first 1 ~ 2 years after planting, it is the development and fruit setting period of honeysuckle plants, and more fertilizers such as human and animal manure, plant ash, urea and potassium sulfate are applied. After planting for 2 ~ 3 years, more fertilizers such as livestock manure, manure, cake fertilizer and calcium superphosphate should be applied in early spring every year. After the first crop of flowers is harvested, an appropriate amount of nitrogen, phosphorus and potassium compound fertilizer should be applied to provide sufficient nutrients for the next crop of flowers. Every year after germination in early spring and when the first flowers are harvested, human feces, fertilizers, etc. They all fell in the open ditch. The application amount of each fertilizer is 250g, and the promotion effect of fertilization treatment on the nutritional growth of honeysuckle is urea+ammonium dihydrogen phosphate, potassium sulfate compound fertilizer, urea and ammonium bicarbonate in turn, among which urea+ammonium dihydrogen phosphate, potassium sulfate compound fertilizer and urea can significantly improve the yield of honeysuckle. Comprehensive nutrition growth, reproductive growth and fertilization cost, the topdressing is urea+ammonium dihydrogen phosphate (150g+65438+.
