The latest course on the planting techniques and methods of Uncaria angustifolia

Spatholobi, also known as Sanguine vine, Spatholobi trifoliata and Celastraceae, is a traditional Chinese medicinal material in China. It has the effects of promoting blood circulation and enriching blood, regulating menstruation and relieving pain, relaxing muscles and activating collaterals, and is an important raw material for many clinical drugs. So how do you plant the spatholobus? Let's take a look.

1. Land selection and preparation

Spatholobus spatholobus is suitable for growing in the environment between 200-3000 meters above sea level, usually growing on the edge of fields, hillside sunshine, roadside shrubs or seaside sand dunes. Planting time to choose a convenient irrigation, leeward damp gentle slope, soil requirements to deep soil, loose sandy loam soil is appropriate. Deep turning once in winter before planting to eliminate overwintering eggs, applying 300-500 decomposed farm manure per mu as base fertilizer when preparing for planting in the next year, shaping, harrowing, ridging, digging drainage ditch, and sterilizing soil if conditions permit.

2. Reproductive methods

The propagation method of spatholobus stem is cuttage. When new buds sprout, strong branches without disease and growing for 1-2 years are selected as cuttings, which are cut into 15-20 cm in length with 2-3 bud eyes on them. The leaves at the base are cut off, the base is inclined into wedges, and the top is cut flat for easy distinction. Cuttings are soaked in rooting powder for 5-10 minutes to improve survival rate, and then inserted obliquely into a small hole with a wooden stick, the cuttings can be inserted into the small hole, the depth is about two-thirds of the cuttings, and at least one bud eye should be exposed. After cuttage cover soil watering, about half a month or so can take root germination.

3. Transplanting

Cuttings survive, the main field management, when the seedlings grow to 40-50 cm can be transplanted, generally in April-May is the best, because then the temperature rises, rainfall, favorable transplanting survival rate. After seedling, dip the roots in viscous yellow mud to keep the roots moist. It is better to trim half or two-thirds of the leaves to reduce the evaporation of water from seedlings and improve the survival rate. Spatholobus spatholobus likes deep forest, mountain side and stream side, as well as its characteristics of winding around other trees, it is best to cultivate under the forest. Dig holes under the forest according to the plant spacing of 2 meters, apply 5 kg farm manure as base fertilizer at the bottom of the pit, spread the root system of seedlings, plant them vertically, cover the soil and tread, and irrigate enough root water.

4. Post-management

After transplanting and surviving, it is necessary to remove the miscellaneous trees and weeds in the forest in time. It is best to use artificial methods to loosen the soil and weed. After loosening the soil, the dead leaves can be covered on the surface to avoid exposing the topsoil. During the growth season of spatholobus stem in July and August, topdressing should be applied once in time to promote its growth, ditch fertilization should be dug near the root system, 5 kg farm manure or 1 jin compound fertilizer should be applied, and soil should be covered timely after fertilization. At the same time, it is necessary to do a good job in the prevention and control of diseases and insect pests. The diseases of spatholobus stem are few, mainly eaten by pests. Chemical agents should be used as much as possible, and pollution-free killing methods should be adopted to reduce drug residues.
