How much is Spatholobus suberectus seed per jin? Detailed planting methods
Spatholobus suberectus is a perennial woody climbing plant of the genus Spatholobus in the Fabaceae family. It gets its name because a red sap flows from a fresh cut. Its dried vine stem is used in medicine, with the effects of enriching blood, invigorating blood, and dredging collaterals. At present, the amount of wild Spatholobus suberectus is decreasing, and resources are gradually becoming scarce. Therefore, artificial cultivation of Spatholobus suberectus has good prospects. Below let us take a look at Spatholobus suberectus seed price and planting methods!
How much is Spatholobus suberectus seed?
The price of Spatholobus suberectus seed is about 50-60 yuan per jin, but prices vary greatly depending on seed quality, variety, market, and other factors. Spatholobus suberectus is a traditional Chinese medicinal material in China and a raw material for many clinical medicines, with huge market demand. At the same time, Spatholobus suberectus is tolerant of poor soil and highly adaptable, sometimes reaching dozens of meters in length, and is also an ideal vine species for urban greening and the treatment of rocky desertification and desertification. In production, it is mostly propagated by sowing, and can also be propagated by cuttings and division.
Sowing methods for Spatholobus suberectus
1. Site selection and land preparation: Choose a gently sloping site with deep soil layers, good drainage and moisture retention, and a sheltered, humid location as the seedbed site. Deeply plow and sun-dry the soil for 5-10 days, apply 800-1000 kg of farmyard manure or 40-50 kg of compound fertilizer per mu, then after deep plowing and making ridges, cover with a layer of raw soil and sow.
2. Seed collection and germination: When Spatholobus suberectus turns dark blue in late autumn and early winter, the seeds can be collected and sun-dried for use as seed. Sow from early April to late May. Before sowing, soak the seeds in 0.3-0.5% potassium permanganate for 24 hours for germination promotion and sterilization treatment. After soaking, remove and air-dry, and sow after half a day.
3. Sowing method: After evenly broadcasting Spatholobus suberectus, cover with a thin layer of soil. After sowing, water thoroughly once with a watering can, but do not pour forcefully to prevent the seeds from being washed away. Then build a 2.5 m high shade shed and cover it with 70% shade netting. Afterward, water as needed to keep the soil moist.
Planting methods for Spatholobus suberectus
1. Bag cultivation: When Spatholobus suberectus seedlings are 5-10 cm tall, remove the weak and keep the strong, and clear weeds. When seedlings are more than 15 cm tall, they can be placed into nutrient bags for cultivation. Do not damage the roots when bagging, and avoid high-temperature weather. After bagging, shade and sun protection are still needed, and water thoroughly once that same day.
2. Transplanting and field planting: Spatholobus suberectus seedlings can be transplanted when they reach 40 cm tall. The best transplanting time is June-July. Add 20-30 kg of decomposed farmyard manure as base fertilizer at the bottom of the planting hole, cover with 20 cm of mature soil, place the seedling in the middle of the hole, add soil and firm it, and water thoroughly once.
3. Cultivation management: After transplanting Spatholobus suberectus, management should be strengthened, paying attention to watering and weeding. Dead seedlings should be replanted in time. When the seedlings grow to 50 cm and are not yet convenient to transplant, guide the vine seedlings onto trees or trellises in time, then apply one topdressing.
4. Pest and disease control: The main disease of Spatholobus suberectus is root rot, which can be controlled by paying attention to drainage. The main pest is spiders, which often occur from May to September. They can be controlled with 800 times dilution of 90% trichlorfon, sprayed once every 7 days, for 2-3 consecutive times.
5. Timely harvest: Spatholobus suberectus can be harvested after two years of planting. It can be harvested throughout the year, but autumn is best. Generally, all parts more than 100 cm from the root can be cut for medicinal use. After harvesting, leave for 3-5 days, then wash clean, and process into 50 cm lengths or slice and sun-dry.
