The Latest Cultivation Techniques and Methods Tutorial for Spatholobus suberectus
Spatholobus suberectus, also known as Xuefengteng, Three-leaf Spatholobus suberectus, and Jiucengfeng, is a traditional Chinese medicinal herb in China. It has the effects of promoting blood circulation and nourishing blood, regulating menstruation and relieving pain, and relaxing sinews and activating collaterals, and is an important raw material for many clinical medications. So how should Spatholobus suberectus be cultivated? Let's take a look.
1. Site selection and land preparation
Spatholobus suberectus is suitable for growing in environments at an altitude of 200-3000 m, and usually grows at field edges, sunny hillsides, roadside thickets, or coastal sand dunes. When planting, it is best to choose a gently sloping site with convenient drainage and irrigation and shelter from the wind and humidity, and the soil should preferably be sandy loam with deep soil layers and loose texture. Before planting, deep-plow it once in winter to eliminate overwintering insect eggs. When preparing to plant the following year, apply 300-500 of decomposed farmyard manure per mu as base fertilizer, shape and rake it level, then form ridges, dig drainage ditches well, and if conditions permit, disinfect the soil.
2. Propagation methods
The propagation method for Spatholobus suberectus is cuttings. When new buds are sprouting, select robust, disease-free branches that have grown for 1-2 years as cuttings, cut them into 15-20 cm lengths with 2-3 buds on them, remove the leaves at the base, cut the base diagonally into a wedge shape, and trim the top flat for easy identification. For cuttings, soak them in rooting powder for 5-10 minutes to increase the survival rate, then use a wooden stick to make a slanted small hole, align the cutting with the small hole and insert it, with a depth of about two-thirds of the cutting, leaving at least 1 bud exposed. After cutting, cover with soil and water, and roots and sprouts will appear in about half a month.
3. Transplanting
After the cuttings survive, the main task is field management. When the seedlings grow to 40-50 cm, they can be transplanted, generally best in April-May, because at this time the temperature rises and rainfall is abundant, which is beneficial to the survival rate of transplanting. After lifting the seedlings, dip the roots in thick yellow mud slurry to keep the root system moist, and also prune off half or two-thirds of the leaves to reduce water evaporation from the seedlings and improve the survival rate. Spatholobus suberectus likes deep mountain forests, hillsides, and stream sides, and because it likes to twine around other trees, it is best to cultivate it under forest. Under the forest, dig holes at a spacing of 2 m between plants and rows, apply 5 kg of farmyard manure at the bottom of the hole as base fertilizer, spread out the seedling root system, plant vertically, cover with soil and firm it, and water thoroughly to settle the roots.
4. Later management
After transplanting and survival, promptly clear away miscellaneous trees and weeds in the forest. Loosening the soil and weeding are best done manually. After loosening the soil, dead branches and fallen leaves can be used to cover the ground surface to prevent the topsoil from being exposed. In July-August, the peak growth season for Spatholobus suberectus, a topdressing should be applied in time to promote its growth. Dig trenches near the root system and apply fertilizer, applying 5 kg of farmyard manure or 1 jin of compound fertilizer, and cover with soil promptly after fertilizing. At the same time, do a good job in pest and disease control. Spatholobus suberectus has relatively few diseases, mainly pests eating the leaves. Try to use chemical agents and adopt pollution-free killing methods to reduce pesticide residues.
