Seed price and planting method of leek

Leek, also known as leek, lazybones, grass bell milk, etc., is a perennial herb of Liliaceae. It is highly adaptable, cold-resistant and heat-resistant, and is widely cultivated all over the country. Leaves, scape and flowers are eaten as vegetables. Seeds and other medicines have the effects of tonifying the kidney, invigorating the stomach, refreshing, antiperspirant and astringent. Let's take a look at the seed price and planting method of leek.

How much is the leek seed per jin?

The price of leek seeds is about 80,150 yuan per jin, which varies according to the quality, variety, origin and market of the seeds. Leek is very adaptable, cold-resistant and heat-resistant. It is cultivated everywhere in our country and can be produced year-round in many areas in the south. Although the aboveground part of the north is dead and the underground part goes into dormancy in winter, it will continue to germinate and grow after the topsoil is thawed in spring. Multi-purpose seed reproduction and plant propagation.

Sowing method of leek

1. Soil preparation and fertilization: deep ploughing and drying of leek seedlings before sowing, making a flat bed, sprinkling 5-7 kg of rotten chicken or pig manure or 8 kg of humic acid ecological fertilizer, 0.1 kg of urea, 0.05 kg of carbendazim and 0.02 kg of 50% carbendazim wettable powder per square meter.

2. Seed treatment: the leek seeds were sunburned for 1 day for 2 days, then stirred in 40 ℃ lukewarm water, removed and scrubbed, soaked in 30 ℃ warm water for 8 hours, germinated under the condition of 18 ℃, washed twice a day with clean water, and 60% of the radicles could be sown when protruding.

3. Sowing time: spring sowing of leek in Huang-Huai Basin is usually from early April to mid-April, from December to February in the south, and from May to June in the north, when the ground temperature is above 12 ℃ and the daily average temperature is 15: 18 ℃.

4. Sowing method: when sowing leek seeds, strip sowing is used, dry seeds per mu of seedling bed are 6kg / mu, vegetable fields of 6000 square meters can be planted, plastic film is covered immediately after sowing, heat preservation and temperature is raised, and the film is removed when the top soil of 70% seedlings.

The planting method of leek

1. Seedling management: after sowing, the leek was watered once every 10 days according to the moisture content of 16 cm, combined with 50 kg of rotten human feces and urine or humic acid ecological fertilizer per mu, and the grass was pulled manually for 2 times at the same time.

2. Land selection and land preparation: for leek cultivation, land with fertile soil and convenient drainage and irrigation should be selected, and 4-5 cubic meters of rotten farm manure should be applied per mu, and the beds should be leveled with a width of 2-3 meters, with a group of 3 borders, with a 1-meter-wide cold belt on the north side.

3. Timely planting: leek was transplanted from late June to early July. Before planting, the ends of the fibrous roots were cut off, the bulbs were cut into small handfuls, and planted in flat beds and holes. It was appropriate not to bury leaf sheaths when planting, and to be steadfast and watered after planting.

4. Field management: after issuing new leaves, leek should be watered slowly and ploughed to preserve soil moisture, keep the soil dry and wet, fully supply fertilizer and water after autumn, and then the temperature decreases gradually, the plant grows slowly, and the surface is not dry.

5. Timely harvest: the leek should be harvested with 7 leaves and 1 heart as the standard, and the harvest is the best in the early morning, and it is appropriate to cut to the yellow leaf sheath of 3 cm above the bulb. After each cut should be slightly higher than the previous stubble, in order to ensure normal growth.

Disease and pest control of leek

1. Leek maggot

[harm] in spring and autumn, the young stem of Chinese chive mainly rotted, which made the leek leaves withered and died. In summer, the larvae moved downwards into the bulb, the bulb rotted and the whole leek died.

[control] 2.5% deltamethrin EC was sprayed per mu in the adult stage, and 1000 times diluted to 1000 times in the larval stage.

2. Grey mold

[harm] White or grayish brown spots appeared on the leaves at the initial stage of the onset of Botrytis cinerea, and then expanded into prismatic or oval spots, which healed each other into large dead spots that withered the leaves.

[prevention and control] the effect of using 78% Kobo 600 times liquid is good, increase the application of organic fertilizer, harvest properly, drain water in time after rain, reduce field humidity, and remove old leaves and diseased seedlings in time.

3. Epidemic disease

[harm] damage to the root, stem and leaf, especially the pseudostem bulb suffered the most, the damage word in the leaf was dark primary color watery spot, then the leaf turned yellow and soft rot, and the stem and root showed brown soft rot.

[prevention and control] spray 1000 times of 50% cinnamon or 2000 times of sclerotia, and spray medicine evenly after each crop of leek harvest.
