Seed price and planting method of licorice

Licorice is a kind of beneficial Chinese herbal medicine, also known as sweet root, red licorice, licorice, etc., is a leguminous licorice perennial herb, strong adaptability, strong resistance, growing in arid and semi-arid desert steppe, desert edge and loess hilly areas, roots and rhizomes for medicinal purposes, let's take a look at licorice seed prices and planting methods!

How much is the licorice seed per jin?

Ordinary licorice seeds are about 20,30 yuan per jin, high-quality licorice seeds are about 50,60 yuan per jin, and large red-skinned licorice seeds in Inner Mongolia are sold for about 100,120 yuan per jin. Licorice generally uses direct seeding methods such as strip sowing, hole sowing, on-demand sowing and sowing, etc. Strip sowing generally needs 6 jin per mu, hole sowing or on-demand sowing generally needs 2 jin per mu, seedling transplanting needs about 2 jin per mu, the yield of fresh products per mu is generally about 1200 jin, and the high producing area can reach 2000 jin.

Sowing method of licorice

1. Soil selection: the cultivation of licorice should choose sandy soil with underground water level below 1.50 meters, good drainage conditions, soil thickness more than 2 meters, no consolidation layer, PH value about 8, convenient irrigation, break bumps and flatten the ground.

2. Seed treatment: before sowing, the seeds of licorice were mixed with 1 kg of seeds and 30 ml of 80% concentrated sulfuric acid, stirred repeatedly with smooth sticks, soaked for 7 hours at 20 ℃, then washed with clean water for many times and dried.

3. Sowing time: licorice can be sown in spring, summer and autumn, among which May is the best in summer, when the temperature is higher, seedlings emerge quickly, and there is a longer growth period before winter.

4. Sowing method: before sowing licorice, 4000 kg of high quality farm manure and 35 kg of diammonium phosphate per mu were applied as base fertilizer, which could be sown by strip or hole, with row spacing of 30 cm, plant spacing of 15 cm, sowing depth of 2.5 cm, and 5 grains per hole. After sowing, the soil was covered with rake to preserve soil moisture.

Planting method of licorice

1. Seedling fixing: when licorice seedlings grow to 15 cm high, the number of seedlings per mu is generally about 12000-15000. If the sowing row spacing is 30 cm, the plant spacing can be kept at 18.5-20 cm.

2. Rational irrigation: licorice should always keep the soil moist before and after emergence to facilitate seedling emergence and seedling growth. Specific irrigation should depend on soil type and salinity. The key to the cultivation of licorice is to protect the seedlings. Generally, the plants will not be watered after they grow up.

3. Weeding in middle ploughing: weeding in licorice is generally carried out in the year of emergence, especially in the seedling stage, licorice roots begin to tiller from the second year, it is difficult for weeds to compete with them, and weeding is no longer needed.

4. Rational fertilization: sufficient base fertilizer should be applied before licorice sowing, and barnyard manure is better. In the sowing year, phosphate fertilizer can be applied in early spring and 2000kg / mu organic fertilizer can be applied per mu before freezing in winter. Because licorice root has the effect of nitrogen fixation, nitrogen fertilizer is generally not applied.

5. Harvest and processing: licorice seeds can be harvested after 3-4 years and rhizomes propagated for 2-3 years. They can be dug when the aboveground stems and leaves wither from late September to early October in autumn, and can also be dug before licorice stems and leaves are unearthed in spring, but the mining quality is better in autumn.

Disease and pest control of licorice

1. Rust

[harm] after being invaded by fungi, yellow-brown blister spots appeared on the back of the leaves, and brown powder was distributed after rupture, and brown-black teliospore piles were formed in August and September.

[prevention and control] concentrate the diseased plants and burn them, and initially spray 0.3-0.4 Baumetu stone-sulfur mixture or 97% rust steel 400-fold liquid.

2. Brown spot

[harm] after being infected by fungi, the leaves produce round and irregular disease spots, the center is grayish brown, the edges are brown, and there are gray-black mildew on both sides of the disease spots.

[prevention and control] the diseased plants were concentrated and burned, and at the initial stage, 1: 1 1: 16 O Bordeaux solution or 70% methyl topiramate wettable powder 1500-200O times.

3. Powdery mildew

[harm] after being infected by semi-symmetrical bacteria in fungi, white powder is produced on both sides of the leaves.

[prevention and treatment] it can be sprayed with 0.2-0.5 Baumetu stone sulfur mixture plus rice soup or flour paste water.

4. Aphids

[harm] Adult and nymphs absorb stem and leaf sap and cause stem and leaf yellowing in serious cases.

[prevention and control] spray 50% fenitrothion 1000-2000 times or 40% dimethoate EC 1500-2000 times or 80% dichlorvos EC 1500 times every 7 to 10 days, several times in succession.
