The latest seed price and planting method of Amomum villosum

Amomum villosum, also known as Yangchun sand, green shell sand, Hainan sand, etc., is a perennial herb of Amomum cardamom of ginger family, distributed in Fujian, Guangdong, Guangxi and Yunnan, cultivated or wild in the shade and wet places of mountains. The fruit is used for medicinal purposes with the effects of moistening appetite, warming spleen and stopping diarrhea, regulating qi and preventing pregnancy. Let's take a look at the seed price and planting method of Amomum villosum together!

How much are seeds?

The price of Amomum villosum seeds is about 60~80 yuan per catty, but the price varies greatly due to the quality, variety, origin and market of seeds. Amomum villosum likes warm and humid climate in tropical and subtropical monsoon rain forest, not cold tolerance, short-term low temperature tolerance,-3℃ freezing death, fear of drought, avoid waterlogging, like diffuse light, to the upper layer of deep, loose, strong soil and sand fertility cultivation is appropriate, production commonly used seed reproduction and plant propagation.

What kinds of amomum are there?

1. Green shell sand: Green shell sand is 1~2 meters high, flowering in April ~ May, capsule spherical or elliptic, slightly triangular, green in appearance, with spiny protrusions, most seeds, mature in August ~ September.

2, red shell sand: red shell sand and green shell sand different leaves are larger, leaf back with villi, fruit smaller, round, red appearance, high fruit rate, but poor quality, cultivation is not much.

3. Yangchun sand: The difference between spring sand and green shell sand is that the capsule appearance is purple-brown, the underground stem is more significant than green shell sand, and the quality is good. It is the main circulating variety in the market.

The seed method of Amomum villosum

1. Seed collection: Amomum villosum seeds mature in about 8~9 months, select plump and healthy fruits, dry the fruits twice before sowing, retting the fruits after sunning, keep the retting temperature (between 30~35℃) and a certain humidity, wash and dry the pericarp in 3~4 days, and sow them in the same place.

2. Soil preparation and fertilization: Amomum villosum nursery land shall be selected from leeward and convenient places for irrigation and drainage, deep ploughing and fine harrowing shall be carried out, the height of the ridge shall be 15cm and the width shall be 1~ 1.2m, sufficient basal fertilizer shall be applied, and 15~ 25kg calcium superphosphate shall be applied per mu, and organic fertilizer mixed with cow dung or compost shall be 1000~ 1500kg.

3. Timely sowing: Amomum villosum is sown in spring in March and autumn in late August to early September, ditching, drilling or dibbling. Before sowing, set up a good scaffold, cover and shade when seedling emergence. The shade degree is 80~90%. When there are 7~8 leaves, the shade can be reduced appropriately, but the shade degree cannot be lower than 70%.

4, seedling topdressing: Amomum villosum seedling first topdressing in 2 leaves with ammonium sulfate nitrogen fertilizer 1.5~2 kg mixed with water 1500 kg, 5 leaves with nitrogen fertilizer 3 kg mixed with water 1500 kg, 10 leaves after topdressing once every half month, mu with nitrogen fertilizer 3 kg mixed with water 1000 kg.

5. Seedling management: Amomum villosum seedlings are often drenched with water to keep the soil moist. In winter and early spring, decomposed cow dung and plant ash can be added to enhance cold resistance. When cold wave comes, wind barriers and fumigation are set up in the north of the ridge. The seedlings are 10~15 cm high. The seedlings are 50 cm high and planted in the nursery.

The cultivation method of Amomum villosum

1. Soil selection: Amomum villosum should choose fertile, loose and water-retaining sandy loam or light clay loam with strong fertility. Broad-leaved evergreen forest land with moisture and water source and hillside, valley and flat land with convenient irrigation can be planted. Sandy soil and heavy clay are not suitable for selection.

2. Forest land consolidation

① Mountain area: before planting in mountain area, open up wasteland, remove weeds and cut down excessive shade trees, and pay attention to replanting in places where shade trees are insufficient, excavate irrigation ditch around mountain to prevent drought and drainage, and at the same time, various fruit trees nearby to expand honey source and attract more insects for pollination.

② Plain: For plain planting, ditch shall be made as ridge, and the ridge surface shall be turtle-back shape to prevent ponding. Attention shall also be paid to creating shade trees. First, fast-growing crops such as banana and green bean shall be planted as temporary shade, and then tall rice trees, jacaranda trees and fruit trees shall be planted as permanent shade trees.

3. Field management

① Before reaching the fruiting period, there should be a large shade degree, 70~80% is appropriate, weeding 5~8 times a year, once a month in rainy season, appropriate nitrogen fertilizer should be applied in addition to phosphorus and potassium fertilizer, 3~4 times in February ~ October every year, pay attention to watering, keep the soil moist.

(2) More sunlight is needed in flower bud differentiation stage after flowering, and it is suitable to keep 50~60% shade on average, but about 70% shade should be kept in sandy soil with poor water retention or lack of water, and weeding should be done twice a year.

4. Disease and pest control

① Stem blight: stem blight occurs in rainy season from July to August. After seedlings are injured, stems dry up and lodge and die. 1:1:1404160 Bordeaux mixture can be sprayed for control.

② Leaf spot disease: leaf spot disease occurs in seedling stage or field. When controlling it, the diseased plants can be removed and sprayed with 1:1:120 times Bordeaux mixture or 1000 times solution of ammonium bromide aqueous solution.

③ Fruit rot disease: pay attention to ventilation and light transmission when preventing fruit rot disease, drain accumulated water, spray 50kg per mu with 1% formaldehyde solution during young fruit period, and sprinkle 15~ 20kg lime plant ash of 1:243 after fruit harvest.

④ Borer: Borer harms seedlings. Water and fertilizer management should be strengthened when controlling it. In the peak spawning period of adults, 40% dimethoate emulsion 1000 times solution or 90% trichlorfon original powder 800 times solution can be sprayed.
