Planting honeysuckle should pay attention to the management of spring. The quality of the spring tube is related to the production of the first and second flowers. The honeysuckle spring tube mainly includes the following two aspects:
prune
In the spring of honeysuckle, the axillary buds give birth to the first branch, and the first branch results in the second branch. In one year, the branch can produce four to six branches. The axillary buds of the new shoots redistribute the shoots, which form inflorescences and flowers. Longer vegetative branches are cut off before budding, and secondary branching shoots will be soon divided to increase flower buds. Generally, flower buds branching from one to four levels can form flower buds, branches after grade four, due to lower temperatures at the end of autumn, can not develop into flowering branches.
Pruning can cultivate trunks, distribute new branches evenly, ventilate and transmit light, expand canopy, produce flowering branches, increase yield and quality. The seedlings planted that year must be pruned in time, topped at a height of 30-40 cm, and cultivated to become the main trunk. On it, 3-5 vegetative shoots were produced, which were developed in three or five branches as the primary branch. When the first branch grows 5-6 leaves and is 15-20 cm long, 3 pairs of strong shoots are left from the base, and the front part is cut off again to promote the growth of the second branch.
top dressing
Spring fertilization, based on available fertilizers. At the time of germination, open shallow ditch and apply diluted manure water or multiple compound fertilizers, and cover the soil immediately after application. In addition, in order to increase the yield, the quick-acting foliar fertilizers such as potassium dihydrogen phosphate and urea can also be sprayed on each foliar.
During the growth period, 0.1-0.2 kg of compound fertilizer was applied to each sapling. In the previous year, the adult trees without basic fertilizer applied in winter were combined with cultivator, and 0.25-0.5 kg of NPK fertilizer was applied to each plant. It is 20-30 cm and it is covered with soil immediately after application. In order to stabilize soil fertility, fertilization methods such as applying fertilizer in winter, compound fertilizer in spring and spraying leaf fertilizer in summer are advocated.
