Field management techniques of common medicinal material Flos Lonicerae

Honeysuckle is often used to prevent colds, clear heat and reduce fire, and it is planted in all parts of our country. Hunan, Shandong, Guizhou and other places are the main producing areas of honeysuckle, and the planting method of honeysuckle is also quite simple. The following is to introduce the field management techniques of the commonly used medicinal material honeysuckle.

I. cultivating soil and weeding

After the honeysuckle is planted and survived, it basically needs to cultivate the soil and weed three or four times a year. Like the honeysuckle planted in the first year, it is necessary to cultivate the soil and weed for the first time when the seedlings reach about 20cm, and in the later stage, it is necessary to cultivate the soil properly according to the growth of honeysuckle. From the second year, the first cultivation and weeding is when the new leaves grow, and the second time is before flowering. The third time was after the first batch of flowers were harvested, and the last time was before Frosts Descent.

2. Fertilization and topdressing

Topdressing is the most critical step in field management, which is directly related to the yield and quality of honeysuckle. Within two years after planting, more fertilizers such as manure, plant ash, urea and potash should be applied. Two years later, scientific fertilization is needed according to different growth periods of honeysuckle. Generally, when branches and leaves grow in spring, they are mainly soil manure and barnyard manure, while pre-anthesis fertilizer is mainly potash fertilizer. After waiting for the first batch of flowers to be harvested, we need to reasonably apply ternary compound fertilizer of nitrogen, phosphorus and potassium, and after the last batch of flowers are harvested, we need to apply urea and fecal water.

Third, reasonable pruning

The pruning of honeysuckle needs to be very patient. generally, the time of pruning is after the leaves fall in autumn or before the branches and leaves sprout in early spring, we should follow the principle of light pruning of strong branches, strong pruning of weak branches and pruning of all branches. it is different from other pruning methods of planting five, each branch needs to be cut off more or less, which is beneficial to the sprouting of new branches and ventilation and light at the same time. For example, the slender ones or the diseased branches and withered branches need to be cut off completely, leaving nothing at all. at the same time, it is important to keep the plant shape and facilitate harvesting and management.

IV. Pruning in time

The main branch of honeysuckle is in its branch and leaf growth period, because the branch growth of honeysuckle is irregular, the growth direction is not consistent, it looks more chaotic, it is not convenient to harvest, it is not easy to manage, and the permeability is not good, so it is easy to reduce the yield, so during its growth period, we should adjust the direction of branch growth and maintain plant shape, ventilation and light transmittance.

Prevention and control of diseases and insect pests

Honeysuckle is more attractive to insect pests, and if the disease is not managed properly, the most common diseases are brown spot and powdery mildew. For brown spot, you need to cut off the diseased branches first. Then use Bordeaux solution or Dyson zinc 500x diluent to control, spray once a week, about two to three times, powdery mildew needs to be cleared in time, and then sprayed with 1000 times of topzine. The main pests are aphids, inchworms, longicorn beetles, etc., which can be sprayed and killed by trichlorfon.
