Seed price and planting method of pea

Bowl beans, also known as cold beans, wheat beans, snow beans, etc., are annual climbing herbs of the genus Leguminosae, native to the Mediterranean and Central Asia, and are now one of the most important cultivated crops in the world. China's main producing areas are Sichuan, Henan, Hubei, Jiangsu, Qinghai, Jiangxi and other places, let's take a look at the seed price and planting methods of bowl beans!

How much is the pea seed per jin?

The price of pea seeds is about 3-6 yuan per jin, but it varies greatly due to the quality, variety, origin and market of seeds. When the pea was propagated by seeds in production, the initial temperature of seed germination was low, the seed germination of round seeds was 1 ℃ and that of wrinkled seeds was 3 ℃, but the seeds germinated slowly and the seedlings had strong cold tolerance at low temperature, the suitable temperature was 15 ℃, the lowest temperature for flowering was 8 ℃, the optimum temperature for flowering and pod formation was 15 ℃, the pod mature stage begged for 18 ℃, and the pod matured prematurely under high temperature and drought.

What kinds of peas do you have?

1. Sweet and crisp: tender pods are light green, crisp and tender in texture and sweet in taste. Each pod has 6-7 seeds. When it matures, it weighs about 200 grams. It is precocious and begins to harvest tender pods about 70 days after sowing. It is suitable for planting in North China, Northeast China, East China and Southwest China.

2. Grassland 31: there are 5 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 tender pod has thick flesh, crisp texture and excellent character, each pod has 5-6 seeds, the seeds are green at maturity, the weight of a thousand seeds is about 200g, the adaptability is strong and the harvest time is long.

4. Grey pea: the seedlings can emerge in 2 days after sowing at 20: 25 ℃, and the seedlings can grow to about 15 cm after 10 days. The leaves are tender and crisp, the character is excellent, and they have wide adaptability to temperature. They can be cultivated at both low temperature and high temperature, so they are suitable for intensive production of pea seedlings.

5. Zhongmu No. 8: there are 711 pods per plant, with 5 seeds per pod, dry early maturing, 400kg green pods per mu, strong drought resistance and cold resistance, so it is suitable for planting in North, Northeast and Northwest China.

Sowing method of Bean

1. Seed selection and germination: before sowing, the seeds of bowl beans are selected with 40% salt water, and the unsubstantial or insect-infested seeds are removed. The seeds are germinated before sowing. When the seeds sprout, the seeds are treated in a low temperature of 0 ~ 2 ℃ for 15 days before sowing.

2. Mixed with rhizobium: after pea was mixed with rhizobium, the root nodule increased, the stem and leaf grew vigorously, the pod was more, and the yield was high. The method of seed dressing is to use rhizobium 10g to 19g per mu, add a little water and mix well with the seeds before sowing.

3. Sowing at the right time: applying sufficient basal fertilizer, especially phosphorus fertilizer, before sowing peas has an obvious effect on increasing yield. Sowing on demand, sowing 2-6 seeds per hole, covering soil 5-6 cm when the soil is wet, slightly thicker when the soil is dry, 10-15 kg per mu.

The planting method of Bean

1. Cultivation system: pea avoid continuous cropping, which can cause toxicity to the following pea and aggravate the occurrence of diseases and insect pests, so it is usually necessary to rotate with other crops. White flower varieties need longer rotation years, and can also be mixed and intercropped with other crops.

2. Land selection: pea cultivated by drip irrigation has a lower plea for soil, which is beneficial to seedling survival and crop growth, so the land with deep soil layer, light soil salinity and medium fertility can be planted.

3. Loosen the soil at the right time: loosen the soil several times after sowing, in order to increase the ground temperature to promote the root growth, the seedlings are strong, cultivate the soil once before overwintering, keep the soil warm and prevent freezing, loosen the soil and weed in time after the beginning of spring, and increase the soil temperature.

4. Rational fertilization: before flowering, pea was irrigated with small water to pursue quick-acting nitrogen fertilizer, and when the stem began to set pods, the amount of water was slightly increased and the amount of phosphorus and potassium fertilizer was applied. The soil should always be moist in the peak stage of podding, and the watering should be reduced in the later stage of podding.

5. Timely harvest: peas should be harvested according to the way they are eaten. Peas are harvested 15-18 days after flowering when the seeds are full, 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.

Disease and pest control of pea

1. Root rot

[harm] the disease can occur from seedling to adult plant, mainly at the base of root or stem, and the leaves of diseased plant yellowed at first, and then gradually developed to the middle and upper parts, resulting in the yellowing and wilting of the whole plant.

[control] seed dressing with 20% triadimefon EC with 0.25% seed weight or 75% chlorothalonil wettable powder with 0.2% seed weight has a certain effect.

2. Brown spot

[harm] the infected leaves showed irregular lavender spots, which spread rapidly under the condition of high temperature and humidity, and then the diseased leaves yellowed and twisted and withered, some showed dark brown irregular ring spots, and black spots appeared in the central necrotic area.

[prevention and treatment] at the initial stage of the disease, 50% carbendazim wettable powder suspension 800 times solution, 70% methyl thiophanate wettable powder 500 times solution, 75% chlorothalonil wettable powder 600 times solution, once every 7 days, 2 times continuously for 3 times.

3. Powdery mildew

[harm] at the initial stage of the disease, the leaves were small yellowish spots, which expanded into irregular powder spots. In severe cases, the leaves were covered with a layer of white powder and finally turned yellow and died, and in the later stage, the powder spots turned gray and grew into many small black particles.

[prevention and treatment] at the initial stage of the disease, spray prevention and control was carried out with 25% fenuoning wettable powder 2000-3000 times, or 70% methyl thiophanate wettable powder 1000 times, or 50% carbendazim wettable powder, or Baume 0.2-0.3 degree stone sulfur mixture, etc.

4. Liriomyza sinensis

[harm] from the young parts of the veins and petioles of the newly hatched larvae to the main stem, pulp and xylem. If the prevention and control is not timely, it will result in a serious reduction in production.

[control] the application of 40% dimethoate, or 40% omethoate, or 50% fenitrothion, or 45% phoxim EC requires 1000 times of water and 75 kg per mu.

5. Leaf miner

[harm] larvae feed in plant leaves or petioles, forming linear or curved irregular insect tracks that affect plant photosynthesis, resulting in economic losses.

[prevention and control] to kill (21% synergistic cypermethrin EC) 800x solution, 2.5% deltamethrin or 20% fenvalerate 2500 times, 10% bromma EC 2000 times, 10% chrysanthemum horse EC 1500 times, 1.8% acaroid and 1.8% fenvalerate 3000 times spray.
