Seed price and planting method of pea

Peas, also known as green beans, cold beans, wheat beans, etc., are annual climbing herbs of the genus Leguminosae, which can be used as food and vegetables. They are native to the Mediterranean and Central Asia, and are now one of the most important cultivated crops in the world. China is mainly distributed in the central and northeastern regions, with high cultivation value. Let's take a look at pea seed prices and planting methods.

How much is the pea seed?

The market price of pea seeds varies according to variety and quality, generally about 815 yuan per jin. At present, the more common varieties are sweet crisp, grassland 31, Jingyin 8625, gray pea, medium pea 8, and so on. The seed shape can be divided into round grains and wrinkled grains, and it should be planted densely when planting. About 30 jin of seeds are needed per mu, and the yield per mu is about 300 jin.

What kinds of peas do you have?

The main results are as follows: 1. Sweet and crisp: the plant is short, the pods are 10-12 per plant, the tender pods are light green, crisp and tender, and the taste is sweet. Each pod has 6-7 seeds, which is relatively early-maturing. It is usually harvested about 70 days after sowing, which is suitable for planting in North China, Northeast China, East China and Southwest China.

2. Grassland 31: the plant is trailing, and there are about 10 pods per plant, with 4 seeds per pod, and the 1000-grain weight is about 250,270 grams at maturity. It is insensitive to sunlight. It can be cultivated in most parts of the country, has strong adaptability and is more resistant to root rot and brown spot.

3. Jingyin 8625: the plant is short, the plant height is about 60cm and 70cm, it has 3 branches, the tender pod is thick, the texture is crisp and tender, the character is excellent, each pod has 5-6seeds, the seed is green at maturity, the 1000-seed weight is about 200g, the adaptability is strong, and the harvest time is long.

4. Grey pea: the plant is short, the seed is round, the weight of 1000 seeds is about 140g, it can emerge 2 days after sowing at 2025 ℃, the seedling grows strongly, the leaf is tender and crisp, the character is excellent, it has wide adaptability to temperature, and it can be cultivated at low temperature and high temperature, so it is suitable for intensive production of pea seedlings.

5. Zhongmu No. 8: there are 711 pods per plant, with 5 seeds per pod, early maturity, 40000kg green pods per mu, drought resistance and cold resistance. It is suitable for planting in North China, Northeast and Northwest China, can be used as green peas and sprouts, and can also be used for grain or feed.

The sowing method of pea

1. Seed selection and sprouting: pea seeds are selected with 40% salt water before sowing to remove unsubstantial or pest-infested seeds. The seeds should be germinated before sowing. When the seeds are sprouting, the seeds should be treated at a low temperature of 0 ℃ for 15 days before sowing.

2. Mixing rhizobium: mixing pea seeds with rhizobium is an effective measure to increase yield. After mixing seeds with rhizobium, there are many pods and high yield. The method of seed dressing is to mix 10-19 grams of rhizobium per mu, add a little water and mix well with the seeds before sowing.

3. Sowing at the right time: before sowing peas, apply fully rotten barnyard manure, compost and phosphorus and potassium fertilizer, sow on demand, row spacing 10-20 cm, plant spacing 5 cm, 2-6 grains per hole, cover soil 5-6 cm when the soil is wet, cover soil slightly thicker when dry, use 10-15 kg per mu.

Management technology of pea

1. Reasonable rotation: pea avoid continuous cropping. Continuous cropping can cause toxicity to the following peas and aggravate the occurrence of diseases and insect pests. It is usually necessary to rotate with other crops, and white flower varieties avoid continuous cropping. The years of rotation should be longer, and it can be mixed and intercropped with other crops.

2. Loosening soil and weeding: loosen the soil several times after sowing, in order to increase the ground temperature to promote root growth, seedling health, autumn sowing cultivation before overwintering, winter heat preservation and anti-freezing, loosen the soil and weed in time after the beginning of spring to improve the soil temperature.

3. Rational fertilization: before flowering, peas were irrigated with small water to pursue quick-acting nitrogen fertilizer, then loosen the soil to preserve soil moisture, slightly increase the amount of water and topdressing phosphorus and potassium fertilizer at the beginning of pod setting, keep the soil moist in the peak stage of podding and reduce watering in the later stage of podding. The bracket begins when the plant is 30 cm high.

4. Pest control: pea diseases mainly include root rot, brown spot, powdery mildew, brown streak, etc., and pests mainly include black miner, leaf miner and so on. Xiaobian has explained in detail in the article "pea pest control techniques". Please read it.

5. Timely harvest: peas are harvested according to the way they are eaten. Peas are harvested when the seeds are full 15-18 days after flowering, dried peas are harvested at 70-80% when the pods are withered and yellow, and vegetable peas are harvested 12-14 days after flowering when the young pods do not appear.
