Branch pruning management method of honeysuckle flower

1. Plastic surgery

The reshaping and pruning work of honeysuckle should be basically completed within 2 years after pruning and planting to form a high-yielding tree. Honeysuckle is a woody vine with large growth and easy shaping. There are three kinds of tree shapes suitable for production, such as dry pier type round head shape, creeping fan shape and hedge type three main branches fan shape.

One is dry pier round head pruning. After planting, the seedlings should top and tip off in time, leave a shoot as the trunk after the new shoots germinate, and erase the rest of the culture. when the trunk branches are 60 cm long, they should top and promote branches, and strive to cultivate three or four robust branches. All the germinating branches on the trunk below 50 cm should be erased to promote them to become thicker and upright into piers. During the first 3 years of trunk training, new branches should be carried out in turn to promote branching, expand to the four branches, and form the upper and lower branches. An umbrella-shaped round-headed tree with an inner and outer circle. The dry pier round head shape is one of the main tree shapes of honeysuckle at present.

Second, creeping fan-shaped plastic surgery. After planting, the new shoot sprouted and left a branch for trunk culture, and when it reached 60 cm long, it topped and branched in time. When the new shoots germinated after topping, all the new shoots below 50 cm in the trunk were wiped off, one new shoot on each side above 50 cm was left for secondary main branch culture, and the new shoot at the apex was used as the main branch to continue to grow. The later three branches were topped every 60 cm, cultivated 2 branches, and gradually formed a three-vine fan-shaped tree with more than two branches. The tree shape is suitable for the conditions of creeping and creeping growth on steep slopes, at the foot of the hill, under the ladder wall, etc.

The third is fencing fan-shaped shaping. The shaping method and steps of the tree are the same as the creeping fan shaping. The difference is that there are hedges, branches are tied horizontally or fan-like tied to the hedges, the trees develop upright to space, have good ventilation and light transmission, and have greater production capacity, which is the main tree shape for high-quality and high-yield standard cultivation.

2. Maintain pruning.

Maintenance pruning is a basic means to regulate the relationship between vegetative growth and reproduction during the whole production period. Under certain cultivation conditions, pruning can control the crown, stabilize the yield, improve the light, reduce the diseases and insect pests, improve the quality, maintain the normal life activities of the tree, and maximize the economic growth years of the tree. To maintain the pruning strength is mainly light pruning, pruning is mainly thinning, pruning is secondary, appropriate short cutting; pruning objects are disease and insect branches, dry and withered branches, dense branches, overlapping branches, senescent branches, etc., that is, cut off disease and insect withered branches, remove dense branches and overlapping branches, and delete useless big branches and short cut senescent branches. The basic principle of maintaining pruning is to get rid of the weak and stay strong, to keep thin, to go up and stay, and to stay inside and out. The pruning time varies with different pruning objects. Pruning disease and insect branches, dry and withered branches combined with garden cleaning is carried out in early winter, pruning daily branches is carried out from late February to early March, and summer pruning such as sprouting, shoot thinning and coring is carried out at any time as needed.

3. Update pruning.

When the plant growth reaches a certain number of years or is affected by bad cultivation conditions, such as plant senescence, yield decline, poor quality and other bad conditions, renewal and pruning should be carried out. The update and pruning took place in the first and middle of March. The regeneration pruning of Flos Lonicerae is mainly retracted, the shoots of all levels on the secondary main branches are retracted to the nodes where there are natural regeneration branches, and the plants without natural regeneration branches are retracted to the nodes of the lateral branches of the secondary main branches. In particular, it is pointed out that renewal and pruning must be based on good fertilizer and water management in order to be effective, and after renewal and pruning, we should do a good job in brushing the trunk branches and applying medicine to the wound (stone-sulfur mixture, etc.), strengthen tree protection, and strengthen shoot management during shoot germination after pruning, so as to promote the rapid formation of new tree shape.
