Seed price and planting method of Amomum villosum

Amomum villosum, also known as Amomum villosum, green shell sand, Hainan sand, etc., is a perennial herb of Zingiberaceae, distributed in Fujian, Guangdong, Guangxi and Yunnan, cultivated or wild in the shady and humid places of mountainous areas. the fruit for medicinal use has the effects of moisturizing and appetizing, warming the spleen and relieving diarrhea, regulating qi and calming the fetus. Let's take a look at the seed price and planting method of Amomum villosum.

How much is the seed of Amomum villosum?

The price of Amomum villosum seed is about 6080 yuan per jin, but it varies greatly due to different seed quality, variety, producing area, market and so on. Amomum villosum prefers warm and humid climate, is not cold-resistant, can withstand temporary low temperature,-3 ℃ dies from freezing, is afraid of drought, avoids waterlogging, and likes diffuse light. It is suitable for cultivation on loam and sandy soil with deep, loose, strong water and fertility conservation in the upper layer, and seed propagation and split propagation are commonly used in production.

What are the kinds of Amomum villosum?

1. Green shell sand: green shell sand is 1 to 2 meters high, flowering from April to May, the capsule is spherical or oval, slightly triangular, green in appearance, with spiny protuberances, many seeds, mature from August to September.

2. Red shell sand: the difference between red shell sand and green shell sand is that the leaf is larger, the leaf back is tomentose, the fruit is smaller, round, red in appearance, the fruit rate is higher, but the quality is poor, and there is not much cultivation.

3. Yangchun sand: the difference between spring sand and green shell sand is that the capsule is purplish brown, the underground stem is more significant than green shell sand red, and the quality is good, so it is the main circulation variety in the market.

Sowing method of Amomum villosum

1. Seed collection: the seeds of Amomum villosum are ripe from August to September. Choose the full and strong fruit, dry the fruit twice before sowing, rett the fruit after drying, keep the retting temperature (between 30-35 ℃) and a certain humidity, wash the pericarp to dry in 3-4 days, and sow in the same place.

2. Soil preparation and fertilization: in the Amomum villosum nursery, select the place of leeward and convenient for drainage and irrigation, deep ploughing fine rake to make the border, the border is 15 cm high and 1-1.2 m wide, and apply sufficient basic fertilizer. 15,25kg of calcium superphosphate mixed with cow dung or compost was applied per mu. 1500 kg organic fertilizer.

3. Timely sowing: Amomum villosum sowing in spring in March and autumn sowing in late August to early September, sowing in trenches or on demand, setting up scaffolding before sowing, adding covering and shading when emergence, the shade degree is 80% 90%, and the shade degree can be reduced appropriately when there are 7 leaves, but the shade degree can not be less than 70%.

4. topdressing at seedling stage: the first topdressing of Amomum villosum at seedling stage was 1.5 kg / mu ammonium sulfate nitrogen fertilizer 1.5 kg / mu mixed with water 1500 kg / mu, 3 kg / mu nitrogen fertilizer / water 1500 kg / mu when 5 leaves, topdressing once every half a month after 10 leaves, and 3 kg / mu nitrogen fertilizer / water 1000 kg / mu.

5. Seedling management: Amomum villosum seedlings are often drenched to keep the soil moist, rotten cow dung and plant ash can be applied in winter and early spring to enhance cold resistance, wind barriers and smoke are set up in the north of the border when the cold wave comes, and the seedlings are 10 to 15 centimeters high and planted in the nursery with a height of 50 centimeters.

Planting method of Amomum villosum

1. Soil selection: Amomum villosum should choose sandy loam or light clay loam with fertile, loose and strong fertility. Broad-leaved evergreen woodland with large humidity and hillsides, valleys and flat land with convenient drainage and irrigation can be planted. Sand and heavy clay are not suitable.

2. Woodland consolidation

① mountain area: open up wasteland before planting, remove weeds and cut down too many shaded trees, but where shaded trees are not enough, we should pay attention to replanting, dig irrigation ditches around the mountains to prevent drought and waterlogging, and at the same time, a variety of nearby fruit trees to expand honey sources and attract more insects to pollinate.

② Plain: planting in the plain should be ditched to prevent stagnant water, and attention should be paid to building shade trees. First, fast-growing crops such as plantains and edamame beans should be planted for temporary shade, and then tall white rice trees, couplet trees and fruit trees should be planted for permanent shade.

3. Field management

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

After entering the flowering and fruiting years, ② needs more sunlight during the flower bud differentiation period, and it is suitable to maintain an average shade of 50% and 60%, but it should be kept at about 70% shade in sandy soil with poor water retention or lack of water resources, and weeds are mainly weeded twice a year.

4. Disease and pest control

① stem blight: stem blight occurs in the rainy season from July to August. After the seedlings are damaged, the stem dries up and loses and dies. It can be sprayed with Bordeaux solution 1 1404160 times when controlling.

② leaf spot: leaf spot occurs in seedling stage or in the field. The diseased plants can be removed during control and sprayed with 120-fold Bordeaux solution or 1000-fold solution of Dysenamine.

③ fruit rot: during the prevention and control of fruit rot, we should pay attention to ventilation and light, discharge stagnant water, spray 50kg per mu with 1% formaldehyde solution in young fruit stage, and sprinkle 15kg of lime plant ash of 123kg after fruit harvest.

④ core worms: drillers harm seedlings, and water and fertilizer management should be strengthened during control. 1000 times of dimethoate emulsion or 1000 times of trichlorfon powder can be sprayed during the peak spawning period of adults.
