Honeysuckle in the cultivation techniques of Flower traditional Chinese Medicinal Materials (part two)

Weeding in field management: three or four times a year, the first time when honeysuckle sprouted in spring, the second time in June, the third time from July to August, and the fourth time in late autumn and early winter. In the third year after honeysuckle planting, depending on the growth of weeds, the times of weeding in intertillage should be reduced appropriately. After thawing in the spring of the third year, a deep turn will be carried out. Deep turning between rows and plants of Flos Lonicerae can not only loosen the soil, but also cut off the old roots on the surface. Topdressing: honeysuckle should be topdressing every year after sprouting in early spring and after each flower picking. Apply fully mature human and animal feces and urine or ammonium sulfate, urea and other nitrogen fertilizer in spring and summer, open a shallow ditch next to the honeysuckle pier, and cover the soil after application; in winter, each pier is treated with fully mature barnyard manure or compost 5kg / 10kg, ammonium sulfate 100g, calcium superphosphate 200g, ring-shaped ditch application around the honeysuckle pier, after application, cover the soil and cultivate the soil. When spraying 0.4%-0.8% potassium dihydrogen phosphate at bud appearance, the yield increase effect is better. Shaping and pruning: through shaping and pruning, honeysuckle can change from winding growth to umbrella-shaped shrub stump with sparse and uniform branches, ventilated and transparent light, stout and upright trunk. As the new branches of Flos Lonicerae can develop into flower branches in the same year, pruning can promote more new branches and form more buds, so as to achieve the purpose of increasing production. Pruning steps: first, set the dry. In the year of spring planting or the second year of autumn planting, the stem is fixed when the branch is about 33 cm long. The trunk generally chooses upright, stout branches and cut off the upper end at 16 to 27 centimeters from the ground. Then select the lateral branches, leave 3 or 5 sturdy branches with uniform distribution and no sunshade on the trunk, and cut off the tip of the stem. After drying, 50 grams of urea and 100 grams of superphosphate were applied per pier, and weeding was often carried out. Second, winter scissors. Have a trim at the beginning of winter. The main purpose is to cut off the branches that grow on the trunk and leave a small number of mother branches that can blossom next year. Because it is a young plant, 4-5 strong branches are selected on the main branch and the upper end is cut off at 3-7 cm. Winter pruning can only be postponed, not in advance. Fertilize once before freezing, and pour frozen water. Third, spring shears. Remove all the buds from the trunk, the middle of the main branch and the rhizome, leaving only the buds on the mother branch. Because the buds will still be produced after the buds are picked, it is necessary to pick the buds many times. Fourth, cut the flowering period. Keep a certain number of mother branches that can blossom, and an appropriate amount of flower branches can be produced in spring, and the shoot should be cut off in time after flowering. Pruning and other management should also be carried out after the second crop flower is harvested. Fifth, trim the adult pier. Honeysuckle entered the mature stage 4 years after planting and the full flowering stage 5 years later, and 4 crops of flowers could be harvested in a year. Pruning is the key, fertilizer and water is the guarantee. Honeysuckle adult pier pruning is mainly for winter pruning. In addition to mastering the essentials of removing weak and staying strong, bending and straightening, removing stack and thinning, but also according to water and fertilizer conditions to determine the number of mother branches. If the condition of water and fertilizer is good, the number of mother branches can be left more to facilitate the flowering of plants in summer and autumn. Pruning is the key to improve the yield of honeysuckle. The principles of pruning are as follows: trunk shaping, light pruning of strong branches, heavy care of weak branches, full pruning of withered branches, pruning of all branches, and re-pruning after flowering. Irrigation and drainage: in the case of dry weather or too much Rain Water during flowering, there will be a large number of falling flowers, retting flowers, rupture of young flowers and so on. Therefore, it is necessary to do a good job in irrigation and drainage in time.
