Honeysuckle likes mild and humid climate, sunshine, cold resistance, drought resistance and waterlogging resistance, and the suitable growth temperature is 20-30℃. 0℃, the requirements for soil and salt and alkali resistance are not strict. The humus soil with deep and loose soil layer is suitable for farming.
The cultivation techniques are mainly seeds and cutting propagation. Seed propagation: sow in April, soak the seeds in warm water at 35-40℃ for 24 hours, take out 2-3 times of wet sand to accelerate germination, and sow when the crack reaches about 30%. Sow seeds in the border according to the row spacing of 2 1-22cm, cover with soil 1cm, spray water 1 time every two days, and sprout after 10 days. Transplanting in autumn or the following spring, using about 65,438+05 kg of seeds every 65,438+0 hm2. Cutting propagation: generally carried out in rainy season. In rainy weather in summer and autumn, cut the robust 1-2-year-old branches into 30-35cm, and use the lower leaves as cuttings. On the selected land, dig pits according to row spacing 1.6m and plant spacing 1.5m, and the pit depth is 16- 18cm. Each pit has 5-6 cuttings, which stand obliquely in a scattered way, with 7- 10cm exposed. Cutting can also be used to raise seedlings; During July and August, the cuttings were placed in the ditch according to the row spacing of 23-26cm, the depth of about 16cm, and the plant spacing of 2cm, filled with soil and compacted, and sprayed with water once after planting. After the drought, water 1 is needed every two days for transportation, which can take root in about half a month and transplant in spring or autumn the next year. Field management: before freezing in February-March in spring and after autumn, soil should be loosened and cultivated. Fertilize 1-2 times a year, and cultivate the soil at the same time, which can be mixed with soil mixed fertilizer and chemical fertilizer. Topdressing 1 time after each flower picking, mainly urea, to increase the number of flower picking. Hefei has mixed feelings. Topdressing 1 time after each flower picking, mainly urea, to increase the number of flower picking. Reasonable pruning and shaping is an effective measure to increase the yield of honeysuckle, which can be carried out according to varieties, pier age and branch type. For example, the trunk of the flower is obvious, with few branches, and the crown width is 80- 120cm. Pruning should be done by removing the top, clearing the foot cluster, drilling into the inner chamber, pruning long branches, weak branches, dead branches and downward extending branches to make the branches stand upright in clusters. Pruning: First, winter pruning can be carried out from 65438+February to the second half of February. The second is frying in the growing period, which is carried out after each flower picking. Summer shoots are cut after the first flower, and autumn shoots are cut after the third flower in early September. Mainly light cutting. Planting honeysuckle in cold areas should protect the old branches from wintering. Generally, before underground freezing, the old branches are laid flat on the ground, covered with wormwood for 6-7cm, covered with soil for wintering, and the covering is removed before germination in the next spring. Pest control diseases include brown spot. In addition to reducing pathogens and strengthening management, 3% Jingfengmycin 5× 10-5(50ppm) solution can be sprayed continuously for 2-3 times at the initial stage of the disease. There are aphids, which can be controlled by chemicals. In July and August, when the temperature is above 25℃ in sunny days, Cerambycidae insects can be released in the field for control, and the effect is good. Inchworm can be controlled by chemicals at an early age.
