Benefit of planting honeysuckle in mountainous area

Honeysuckle is resistant to cold, drought and barren, and does not occupy cultivated land when planting. Honeysuckle is planted on hillside or in combination with returning farmland to forest and soil and water conservation. As long as the technology is proper and the benefit is considerable, it is a good way for farmers in mountainous areas to generate income. According to the investigation, honeysuckle is planted on the ridge, the pier distance is 70cm to 80cm, it can cover the ridge for 3 years, it can protect the ridge without gully, and the stone ridge will not collapse. At the same time, honeysuckle does not have strict requirements on climatic conditions and has a strong ability to resist drought. there is a saying that "drought kills weeds, but honeysuckle does not die in drought". Its planting characteristics are as follows:

First, land selection and land preparation. Honeysuckle likes sunshine, is cold-resistant and drought-resistant, and is not strict with the soil. Select slopes with thicker soil layers and make fish-scale pits or trapezoidal fields according to the topography, or abandoned or low-yield slopes, applying 5000 to 6000 kg of rotten soil and miscellaneous fertilizer per mu. The seedling field should be watered.

Second, planting technology. Seedling transplanting or cutting can be done. Seedling transplanting has the characteristics of high survival rate and quick production. Select a large number of flower branches, short internodes of 1-2-year-old strong branches, combined with winter or summer shears, cut into 20 cm segments, remove the lower leaves, obliquely planted in the pre-opened planting ditch in the seedling field, the branches are buried in 2/3, and then watered thoroughly. Summer seedlings take root about half a month, the seedling height of more than 60 cm, the second year before germination out of the nursery for transplanting. The seedlings raised in winter can be transplanted when the height of the seedlings in the second year is more than 50 cm. Avoid long-distance transportation in summer when transplanting to prevent damage to seedlings. The holes were opened according to the distance between rows and plants of 1 × 1.5 meters, and 8 plants were planted in each hole, 4 plants in the middle and 6 plants around them. Direct cutting according to the row spacing and number of plants transplanted can be carried out except for the time of permafrost in cold winter.

After transplanting, the withered branches and leaves at the base of the flower pier are removed at the end of autumn every year, and the surrounding soil is renovated. 5-10 kg of soil fertilizer is applied to each pier, 0.5 kg of superphosphate is applied conditionally, fish scale pit or combined with soil cultivation is added to the outer edge of the pit to store rain and snow.

Scientific pruning is a key measure for high yield cultivation of Flos Lonicerae. Winter scissors and summer scissors. Winter shearing is the main principle, and the principle is "light cutting of strong branches, heavy cutting of weak branches, full cutting of dead branches, and cutting of all branches". It is mainly considered that in the process of flowering, the plant type is complete and reasonable, the branches are extended, the density is moderate, it is beneficial to ventilation and light, and the diseased branches, winding branches and cross branches should be completely cut off. After the summer flowering, the new flower branches are promoted in accordance with the principle of strong branches and weak branches, so that the florescence of the two flowers is the same and easy to pick. And get rid of vegetative branches and tillering branches in time.

The medicinal honeysuckle in the south of Shandong Province matured from late May to early June. The upper part of the bud is enlarged, and the bluish white is the suitable time for picking. If the flower buds are picked too early, the yield is low; if the flowers bloom too late, the yield and quality will decline strictly. Harvest buds every morning and in the morning, dry or dry them in the sun.

Third, benefit analysis. After transplanting in spring, most of them blossomed in the same year, and most of them bloomed in the second year, and then the yield increased year by year. According to 330 piers per mu, as long as it was properly managed, the annual yield of honeysuckle was 130-150 kg, calculated at the price of 30-40 yuan per kilogram in normal years, and the benefit per mu was 4000-6000 yuan.
