Seed price and planting method of lentil

Lentils, also known as lentils, beans, white lentils, etc., are perennial vines of the genus Leguminosae. They are cultivated in all tropical and subtropical regions, with red and white flowers, green pods, light green, pink or purplish red, and tender pods, which are often used as vegetables and have high cultivation value. let's take a look at the seed prices and planting methods of lentils.

How much is the lentil seed per jin?

The price of lentil seeds is about 150,200 yuan per jin, but there is a great difference in price due to different varieties, quality, producing areas and purchased quantity, generally about 3 jin per mu. Lentils like warm, humid and sunny environment, the suitable germination temperature is 22 ~ 23 ℃, the plant can withstand about 35 ℃ high temperature, strong root system, strong drought tolerance, good adaptability to all kinds of soil, planting in well-drained and fertile sandy soil or loam can significantly increase yield, and can be cultivated by riverside, field, front and back of the house.

Sowing method of lentil

1. Sowing time: lentils can usually be sowed one after another after mid-January, but the sowing time is also different in different regions. For example, the planting time of lentils in the Yangtze River basin is from May to the end of July. The planting time of lentils in North China is mostly sown in June.

2. Seedling bed arrangement: lentils are easy to choose fertile and loose vegetable field soil as seedling bed, turn deep to sun for a week, fine broken soil, sieve out fine soil for nutrition bags, seedling bed according to 1.2 meters net moisture surface, 30 cm ridge width to manage soil moisture, make high ridge and low soil moisture, smooth moisture surface.

3. Nutrition seedling: lentil seedling nutrition bag is packed with sifted fine soil, 3 bags of soil is filled with 4 seeds, and then the nutrition bag is filled and discharged in the seedling bed. After pouring water through the bucket, the nutrition bag is covered with a layer of straw or loose hair, and finally covered with flat film.

4. Seedling management: lentils should be checked frequently after sowing. Once sprouting, the seedlings should be ventilated in time, the mulch should be removed, and the flat film should be changed into a small arch shed. In case of a sudden drop in temperature at night, a straw mat should be added outside the small arch shed to prevent frost.

Planting method of lentil

1. Field arrangement: lentil planting fields are deeply turned and sunburned for one week, 2 tons of farm manure per mu are applied, and fine broken soil is made into high soil moisture and low ridges, planting ponds are made on the soil moisture surface, wide and narrow rows are made into wide rows of 45 cm plant spacing, and narrow rows are planted in 2 ways according to 1.5 × 0.45 m plant spacing.

2. Timely transplanting: lentils are usually transplanted after mid-February or when the seedlings have one leaf and one heart. When transplanting, 5: 10kg compound fertilizer per mu is sprinkled in the sowing pond and mixed with the soil. After transplanting, the film is covered and compacted on the soil surface, the film is pierced to pull out the lentil seedlings, and finally poured through the fixed root water.

3. Plant adjustment: after the lentil survived, the lentil was put into the pile and put on the pile in time. After entering the vigorous growth period, we should often beat leaves, get rid of dense leaves, diseases, insects, old leaves to reduce nutrient consumption, increase ventilation and light transmittance, which is conducive to the growth of flat pods.

4. Fertilizer and water management: 20 days after transplanting, 5 kg of urea and 10 kg of compound fertilizer per mu were irrigated with water, once or twice before harvest, once every 15 days after entering the harvest period, and 5 kg of urea and 10 kg of compound fertilizer per mu.

5. Timely harvest: lentils can be eaten from young pods to old pods, and can be harvested timely according to the needs of the market. Lentils with plant characteristics, full grains and bright skin color should be selected before and in the middle of harvest until the pods with dry skin are harvested.

Disease and pest control of lentil

1. Mosaic virus disease

[symptoms] occur before or after anthesis, the leaves appear slightly yellowish green mottled, the leaves become smaller or clear veins, some heart leaves are not stretched or shortened internodes, distorted deformities, some are systematic ring spots, and the diseased plants are short.

[control] varieties with strong disease resistance were selected for ①. ② established a disease-free field, pulled out diseased plants in time, and selected bean seeds that were disease-free and brown spot-free. ③ strengthens fertilizer and water management and improves plant disease resistance. ④ can control aphids as early as possible to prevent the spread of virus.

2. Rust

[symptoms] damage to the leaves, the leaves after the injury of the primary yellow-white spots, slightly protruding, and then gradually enlarged to show rust-brown protuberant disease spots, the inducing factors are high temperature and high humidity, generally from July to August is the peak period.

[prevention and control] the removal of disease and residue in the field can be controlled with 65% Dysen zinc wettable powder 1000 times, 70% methyl topiramate wettable powder 1000 times or 50% carbendazim wettable powder 800-1000 times.

3. Leaf spot

[symptoms] at first, there were purple-brown spots on both sides of the leaf, and then expanded into a circle, and dark green or dark brown mildew appeared on the surface of the disease spot, which was easy to occur under the condition of high temperature and humidity, and the disease was more serious in continuous cropping than in rotation, and it was also serious in the case of poor ventilation and light transmission.

[prevention and treatment] increase the application of potash fertilizer, improve plant disease resistance, spray 1000 times of 70% methyl thiophanate wettable powder or 1000 times of carbendazim wettable powder in the early stage of the disease, spray once every 7 to 10 days, and spray 2 times continuously for 3 times.

4. Small gray butterfly

Symptoms: larvae eat buds and pods, often empty ovaries and stamens, and lose commercial value when pods are eaten.

[control] spray 2500 times of 24% methoxyfenozide suspension or 2000 times of 5% fipronil suspension during the peak period from August to October.

5. Erythema

[symptoms] the disease spot on the leaf is nearly round to irregular, sometimes develops along the vein, the spot size is 2mm 9 mm, red to brownish red, the back is densely covered with gray mildew layer, sometimes on the leaf surface, and sometimes infects the pod.

① selected disease-free plants to leave seeds, and the seeds were soaked in warm water for 45 ℃ for 10 minutes before sowing. After harvest, deep ploughing was carried out in the areas affected by ②, and rotation was carried out under conditions. At the initial stage of ③, 78% wave manganese zinc (Cobo) wettable powder was sprayed, or 75% chlorothalonil wettable powder was sprayed 600x, 53.8% could kill 2000 dry suspension 1000 times, once every 7 to 10 days, continuous prevention and treatment for 3 times.
