As the saying goes: "Three-point planting and seven-point management", the yield of naturally grown honeysuckle is low, and scientific management is necessary to obtain high yield. The management of honeysuckle includes the following three aspects:

1, plastic pruning: honeysuckle has strong natural regeneration ability, with many new branches and buds on them. Natural growth of honeysuckle. It is because the plants grow too densely, the ventilation and light transmission are poor, the leaves are easy to yellow and fall off, and the number of flowers is small. Although the flowering branches can continue to grow, they can no longer bear buds and flowers. Only on the original flowering mother branch, new branches germinate and flower buds differentiate to form buds, so they must be trimmed from winter to the next year. Only through reasonable pruning and control of plant shape and branch development can new branch germination, flower bud differentiation and bud formation be effectively promoted. The shaping and pruning are well done, and the output can be increased by more than 40%. Honeysuckle below 0℃ enters dormancy period. Winter to the next spring is the best time for plastic surgery and pruning. The flower piers under 4 years old are young flower piers, and the task of pruning is to select and retain the backbone branches and cultivate the pier shape. When pruning, in the first year, select robust branches and cut them off at 3-5 knots, leaving them as primary backbone branches, leaving 6-8 branches for each pier and cutting off the rest. In the next two years, you should reshape it first and then trim it. You can adjust the distribution of primary branches and sparse redundant branches by pulling branch shaping. Choose to leave 2-3 level backbone branches, 3-5 nodes for strong branches and 2-3 nodes for weak branches on the first level backbone branches. The short-cut branches are called flowering mother branches, and 50-80 flower piers are left within 3 years, and about 100 flower piers can be left in 4 years. The flowering mother branches should be evenly distributed, with a spacing of 8- 10 cm. The shape of the flower pier has been adjusted for more than 5 years. The main task of pruning is to select and keep strong flowering mother branches. When pruning, old and weak branches, sick and disabled branches, diseases and insect pests branches, cross branches and drooping branches should be cut off first, so that steep long branches can be shortened and cultivated into new backbone branches. If we constantly discard the weak branches, we can make the flower pier younger. Then, according to the previous method, all branches are cut off, leaving the flowering mother branches of each pier 100- 120 and the fertile pier 120- 150 in the mountainous area. After pruning, clear the pier and tidy up the holes, and carry out planned root cutting combined with deep ploughing, which can promote rhizome development, improve root activity and increase yield, and the total amount of root cutting at one time should not exceed 1/4 of the total root amount. Burying the dead leaves of Qingdun can effectively eliminate hidden eggs and prevent the occurrence of pests and diseases, and can also be used as compost to improve the soil, killing two birds with one stone. After pruning, clear the garden, bury or burn the branches of pests and diseases, and the strong branches can be used as seedlings. When winter goes and spring comes, carefully trimmed flower piles will grow more branches and bear more buds than before. Honeysuckle is pruned after harvest, and the purpose of pruning is to promote the formation of multi-crop flowers. The first green cutting was in late May after the first flower, and the main green cutting methods were thinning and cutting. Only now the buds of honeysuckle are born on new branches, and these picked branches will not regenerate buds, so they need to be chopped to promote the germination and bud formation of new branches. According to the type and geographical location of piers, each pier is reserved with 100- 150 flowering mother branches. Combine pruning, remove pests and branches, and clear the garden in time after pruning. Green pruning can be used 2-3 times a year, and 3-4 flowers can be harvested. 2. Rational fertilization: Rational fertilization is the basis of high yield, and fertilization can be divided into base fertilizer and topdressing. The base fertilizer is used once a year, and the blinds wither in June165438+1October, which is the ideal season for fertilization. Base fertilizer, also known as root fertilizer and overwintering fertilizer, is mainly farmyard fertilizer, and each flower pier is 3-5 kg. Top dressing 3-4 times a year. When spring returns, apply bud fertilizer before the buds bloom. According to the size of the pier, about 50 kilograms of nitrogen fertilizer or the same N.P.K compound fertilizer should be applied per mu. Top-dressing flower fertilizer after each green branch cutting, using 30-50 kilograms of compound fertilizer per mu, watering after fertilization where conditions permit, and giving full play to the fertilization effect. Spraying diammonium hydrogen phosphate (3: 1000) solution before each flower bud differentiation can promote plant growth and increase bud yield by nearly 20%.

3. Pest control: Insect pests are the main reason for the yield reduction of honeysuckle, and winged moths and inchworms are leaf-eating pests of honeysuckle. The fifth instar larvae enter the stage of gluttony, and when it is serious, they can lose everything. Cerambycidae, Cerambycidae and Cerambycidae eat branches, although the number is small, it often leads to the death of Huadun. When this kind of insect occurs, it should be uprooted and eliminated in time to prevent its spread. Aphids harm leaves and shoots, leading to a decline in yield, which mostly occurs during bud pregnancy and flower picking. If aphids suck young leaves and shoots, they should be prevented once they are found. Prevention and control can be used: 30% Taoxiaoling EC 2500 times solution. Spray winged moths and inchworms with 3000 times of 25% oil slick, and trap moths with lights. The brown spot disease of honeysuckle occurred seriously in July and August. 30% validamycin 50PPm or Bordeaux solution 1: 1.5: 200 once every 7- 10 days, 2-3 times in total. It is strictly forbidden to use highly toxic pesticides in honeysuckle, and the drug should be stopped 10 days before flower picking.
