Latest Prices of Hyacinth Bean Seeds and Detailed Planting Methods

Hyacinth bean, also known as skin hyacinth bean, yardlong bean, white hyacinth bean, etc., is a perennial twining vine of the genus Lablab in the Fabaceae family. It is cultivated in tropical and subtropical regions. The flowers are red or white, and the pods come in colors such as green-white, light green, pink, or purple-red. The tender pods are often used as a vegetable and have extremely high cultivation value. Now let us take a look at hyacinth bean seed prices and planting methods!

How much does a jin of hyacinth bean seeds cost?

The price of hyacinth bean seeds is about 150 to 200 yuan per jin, but prices vary greatly depending on variety, quality, place of origin, and purchase quantity. Generally, about 3 jin of seeds are used per mu. Hyacinth bean prefers a warm, humid environment with plenty of sunlight. The suitable germination temperature for seeds is 22 to 23 degrees C. The plant can tolerate high temperatures of around 35 degrees C. Its root system is well developed and strong, with strong drought tolerance and good adaptability to various soils. Planting in well-drained and fertile sandy soil or loam can significantly increase yield. It can be cultivated along riversides and roadsides, at field edges and corners, and around the front and back of houses.

Sowing Methods for Hyacinth Bean

1. Sowing time: Hyacinth bean can generally be sown successively after mid-January, but sowing times differ by region. For example, in the Yangtze River Basin, hyacinth bean is sown from May to the end of July, while in North China, hyacinth bean is mostly sown in June.

2. Seedbed preparation: For hyacinth bean, it is easy to choose fertile, loose vegetable garden soil as the seedbed site. Deeply plow and sun-dry the soil clods for 1 week, break up the soil clods finely, and use a sieve to sift out fine soil for filling nutrient bags. Prepare the seedbed with a 1.2 m clear bed surface and 30 cm ridge width, making high ridges and low beds, and level the bed surface.

3. Nutrient seedling raising: Fill the hyacinth bean seedling nutrient bags with sifted fine soil. After filling 2/3 of the bag with soil, place 4 seeds inside, then fill the nutrient bag full. Arrange them in the seedling bed. After watering thoroughly with a watering can, cover the nutrient bags with a layer of rice straw or pine needles, and finally cover with a flat film.

4. Seedling management: After sowing hyacinth bean, check frequently. Once sprouts emerge, ventilate and harden the seedlings in time, remove the covering, and change the flat film to a small arch shed. If the temperature drops suddenly at night, add grass mats outside the small arch shed to prevent frost damage.

Planting Methods for Hyacinth Bean

1. Field preparation: Deeply plow and sun-dry the hyacinth bean planting field for 1 week, apply 2 tons of farmyard manure per mu at depth, break up the soil clods finely, make high beds and low ridges, and dig planting holes on the bed surface in wide and narrow rows. The wide row has a plant spacing of 45 cm, and the narrow row is dug as 2 rows of planting holes at a spacing of 1.5×0.45 m.

2. Timely transplanting: Hyacinth bean is usually transplanted after mid-February or when seedlings have 1 leaf and 1 heart. When transplanting, apply 5 to 10 kg of compound fertilizer per mu into the sowing holes and mix evenly with the soil. After transplanting, cover the bed surface with film and press it firm, puncture the film and pull out the hyacinth bean seedlings, and finally water thoroughly to settle the roots.

3. Plant adjustment: After hyacinth bean survives, insert stakes and build trellises in time, and guide the vines onto the stakes. After entering the vigorous growth period, remove leaves frequently. Remove overly dense leaves and diseased, pest-damaged, and old leaves to reduce nutrient consumption, increase ventilation and light penetration, and benefit the growth of hyacinth bean pods.

4. Fertilizer and water management: 20 days after transplanting hyacinth bean, apply 5 kg of urea and 10 kg of compound fertilizer per mu dissolved in water. Water with fertilizer 1 to 2 times before harvest. After entering the harvest period, topdress once every about 15 days, applying 5 to 10 kg of urea and 10 to 30 kg of compound fertilizer per mu dissolved in water.

5. Timely harvest: Hyacinth bean can be eaten from tender pods to old pods, and can be harvested at the appropriate time according to market demand. For seed-purpose hyacinth bean, choose pods from plants in the early to mid-harvest period that have the characteristics of this variety, plump seeds, and bright skin color, and harvest them when the skin shrivels.

Pest and Disease Control for Hyacinth Bean

1. Mosaic virus disease

[Symptoms] Occurs before or after flowering. Slight yellowish-green mottling appears on leaves, leaves become smaller or veins become clear, some heart leaves do not unfold or internodes shorten, twisting and deformity occur, and some show systemic ring spots. Diseased plants are stunted.

[Control] (1) Choose varieties with strong disease resistance. (2) Establish disease-free seed fields, remove diseased plants in time, and select truly disease-free bean seeds without brown spots for seed. (3) Strengthen fertilizer and water management to improve plant disease resistance. (4) Control aphids early to prevent virus spread.

2. Rust disease

[Symptoms] It harms leaves. After leaves are damaged, small yellowish-white spots first appear, slightly raised, and then gradually expand into rust-brown raised lesions. The inducing factors are high temperature and high humidity. The peak incidence period is generally July to August.

[Control] Remove diseased residues from the field and burn them in a centralized manner. Control can be carried out with 65% zineb wettable powder 500 times solution, 70% thiophanate-methyl wettable powder 1000 times solution, or 50% carbendazim wettable powder 800 to 1000 times solution.

3. Leaf spot disease

[Symptoms] Initially, purple-brown spots appear on both sides of the leaves, later expanding into round shapes. Dark green or dark brown mold-like substances grow on the surface of the lesions. The disease occurs easily under high temperature and high humidity conditions. Continuous cropping fields are more severely affected than rotated fields, and incidence is also more severe when ventilation and light penetration are poor.

[Control] Increase potassium fertilizer application to improve plant disease resistance. In the early stage of disease, spray promptly with 70% thiophanate-methyl wettable powder 1000 times solution or 50% carbendazim wettable powder 1000 times solution, spraying once every 7 to 10 days, for 2 to 3 consecutive sprays.

4. Lycaenid butterfly

[Symptoms] Larvae bore into and feed on flower buds and pods, often eating the ovary and stamens hollow, and infested pods lose commercial value.

[Control] During the peak occurrence period from August to October, spray 24% methoxyfenozide suspension concentrate 2500 times solution or 5% fipronil suspension concentrate 2000 times solution.

5. Red spot disease

[Symptoms] Leaf lesions are nearly round to irregular, sometimes developing along the veins. The spots are 2 to 9 mm in size, red to brownish-red, with dense gray mold layers on the underside, sometimes also on the leaf surface, and in severe cases they infect pods.

[Control] (1) Select disease-free plants for seed retention, and disinfect seeds before sowing by soaking in 45 degrees C warm water for 10 minutes. (2) After harvesting in diseased fields, carry out deep plowing, and implement crop rotation where conditions permit. (3) In the early stage of disease, spray 78% bordeaux mixture · mancozeb (Kebo) wettable powder 600 times solution, or 75% chlorothalonil wettable powder 600 times solution, or 53.8% Keshade 2000 dry suspension concentrate 1000 times solution, once every 7 to 10 days, for 2 to 3 consecutive controls.
