Planting techniques of Flos Lonicerae

In recent years, China has made a breakthrough in the development and utilization of Chinese herbal medicine honeysuckle. Not only the dosage of medicine has increased, but also there is a strong demand in the fields of fresh food, spices, chemical industry and health food. At present, the annual output of honeysuckle is about 5 million kilograms, and the price per kilogram has risen from 18-20 yuan to 30-40 yuan, while the annual social demand in the next few years will reach 17 million kilograms, resulting in a large gap between production and demand. It can be seen that the development of artificial planting of honeysuckle is not only a broad market, but also has good economic benefits. Honeysuckle, originally wild, is an evergreen trailing shrub with fragrant buds and has the effect of heat-clearing and detoxification. It has strong vitality, wide adaptability, resistance to drought and barren, can grow well in slightly acidic and slightly alkaline soil, and can be planted in barren wasteland with serious soil erosion, which can not only conserve soil and water, green environment, but also increase income. Artificial cultivation of honeysuckle, less investment, quick results, extensive management, and planting for many years, with an annual income of 7000 yuan per mu, is a good project for the development of diversified economy in poor areas.

Now the main points of planting and harvesting techniques are introduced as follows for developers' reference.

First, cultivate strong seedlings: the propagation method of honeysuckle can mainly raise seedlings. First of all, prepare the seedling bed, you can choose neutral or slightly acidic, slightly alkaline fertile soil as the seedling bed. Turn the ground to a depth of 30-40 cm, rake the broken soil flat and compact it slightly, make it into a border 1 meter wide, open a ditch according to the row spacing of 15-20 cm, and put a layer of soil fertilizer in the ditch as base fertilizer. Then, choose the vine cut and cut. The spring vines of the year with strong growth, strong disease resistance, many flowering and sturdy vines should be selected as seed vines, cut into a section of every 3 buds with scissors (about 20 cm long), and one end of the soil should be cut into a bevel. After being treated with rooting powder or seed nutrients and plant ash, according to the requirement of plant row spacing of 4 × 15-20 cm, planting sweet potato seedlings should be inserted into the soil with a depth of about 7-8 cm (a bud must be buried in the soil). Then cover the soil and compact, flatten the ditch, water it once, and pay attention to shade and sunscreen. Second, take good care of the seedbed. After the new seedlings grow, remove the shade in time and keep the soil moist. When the seedling height is 10 cm, dung water or nitrogen fertilizer should be applied thinly, and attention should be paid to picking the heart and topping, so as to promote the development of the root system and the stout of the main stem, so as to lay the foundation for transplanting.

Second, timely transplanting when the seedling age is one year, the seedlings can be transplanted in the season from the Spring Equinox to Grain Rain, and the density is determined by the soil quality, usually the distance of each hole is 2 × 2.5-3 meters. Before transplanting, dig holes 60-70 cm wide and 40-50 cm deep, and apply enough farm manure, 30-50 kg per hole. 1-2 plants per hole is suitable for fertile soil, 3 plants can be planted in one hole in lean soil, and the number of holes per mu is controlled at about 120 to 140.

Third, field management should be watered in time after transplanting to ensure the survival rate. After one month, apply light feces and urine water or 1 Ru 300 nitrogen fertilizer water every 15 days or so. When the new buds grow to more than 2 nodes, pick the heart in time, promote the lateral branches to form clumps early, and set up the frame at the right time according to the length of the vine, so as to facilitate the winding growth of the new vine. After picking flowers, it is necessary to timely cut off diseased, withered and weak branches, weed and loosen the soil, and apply fertilizer to ensure high yield in the coming year.

Fourth, pest control and disease control are mainly budding and powdery mildew. The basic drugs for prevention and treatment can be sprayed with colloidal sulfur mixture, that is, colloidal sulfur 100g, trichlorfon 10g, dimethoate 15g, plus 30kg water, generally every 15 days.

Fifth, flower picking and processing should be timely from May to June. The processing method can be dried in the shade, dried or smoked with sulfur, then dried in the sun, or dried in a light fire or electric oven, but the appropriate temperature should be mastered to make the color and dryness just right to prevent blackening. It should be sealed and stored after drying to prevent damp discoloration and moth.
