According to the "Compendium of Materia Medica", peas have the effect of "eliminating facial dark spots and making the face shiny." Modern research has found that peas are rich in vitamin A, and vitamin A can be converted into vitamin A in the body, which has the effect of moisturizing the skin. Because it is generally taken from food, it does not produce toxic side effects. So how is pea grown? How to manage it during the period?
Folding ecological features
Pea likes freezing and humid climate, cold tolerance, heat resistance, seedlings can withstand 5 ° C low temperature, suitable temperature for growing season 12 ~ 16 ° C, pouring period suitable temperature 15 ~ 20 ° C over 25 ° C low fertilization rate, less pods, low yield.
Peas are long-day plants. The growth period of most varieties is shorter in the north than in the south. The southern variety migrated to early flowering and pod formation, which shortened the wintering seedling stage in the north. Therefore, in the north, the growth period of peas, early maturity of 65-75 days, medium-ripe species 75-100 days, late-maturing species 100~ 185 days.
Although the peas have strict requirements on the soil, they can be planted on well-drained sandy soil or in new land, but it is suitable to loosen neutral (pH 6.0-7.0) soil with high organic matter, which is beneficial to emergence and rhizobium. Development, soil acidity below pH 5.5 is prone to disease and reduce pod formation rate, should be applied with lime. The roots of peas are deep, slightly drought-tolerant and not resistant to moisture. The sowing or seedlings are poorly drained and easily rotted, and the drought is poorly fertilized, which is easy to form empty pods or pods.
Folding soil conditions
Peas require less soil conditions and can be cultivated in a variety of soils, but lime is applied to strongly acidic soils. The peas are most prone to continuous cropping, at least for 4 to 5 years. Before planting, it is necessary to deepen the soil, apply 2500-3000 kg of organic soil per mu, 20-25 kg of superphosphate, and 15-20 kg of potassium chloride. It is best to mix the fertilizer with organic fertilizer. Generally, it is flat, and the low dust mites can be used as sorghum. Seeds can be inoculated with Rhizobium before sowing.
Folding seeding technique
Seeds were selected with 40% saline prior to sowing to remove seeds that were not full or infected with insects. The seed is germinated before sowing, and when the seed is bud, the seed is treated at a low temperature of 0 to 2 ° C for 15 days and then sown.
Seed dressing of peas with Rhizobium is an effective measure to increase production. After seed dressing with Rhizobium, the nodule increased, the stems and leaves grew vigorously, the pods were many, and the yield was high. Seed dressing method: 10 to 19g of rhizobium per acre, add a little water and mix well with seeds to sow.
Before the planting of the field, fully fermented manure, compost and a certain amount of phosphorus and potassium fertilizer were applied. Especially, the application of phosphate fertilizer increased the yield. The peas were on-demand, the row spacing was 10-20 cm, the spacing of the plants was 5 cm, and 2 to 6 seeds were planted per hole. Cover the soil 5~6cm when the soil is wet. The soil is slightly thicker when the soil is dry. 10 to 15 kg per mu.
Folding field management
After sowing, the soil should be loosened several times to increase the ground temperature to promote root growth, and the seedlings are strong. Cultivated in autumn sowing, the soil is cultivated once before winter, and the winter is warm and anti-freeze. After the spring, the soil is weeded and the ground temperature is raised. Before peas bloom, pour small water to chase fast-acting nitrogen fertilizer, accelerate plant growth, promote sub-technique, and then loosen the soil. When the stem begins to sit on the pod, the amount of water is slightly increased, and the phosphorus and potassium fertilizers are chased. The soil should always be moisturized during the pod season. Ensure the water needed for fruit pod development. At the end of the pod, the soybean meal seals the ridge and reduces watering. When the vine planting height is 30 cm, the stent is started. The peas are harvested in batches, and each time the harvest is 1 time.
Folding harvest time
The pods are harvested when the pods are fully grown and the kernels have not grown. Peas continue to flower and pod, and harvesting should be carried out several times. The spring-sowed peas began to be harvested in early April. In early June, the peas were pulled and the yield was 400kg per mu. The autumn-sown peas were harvested from early October to mid-November, with a yield of 300kg per mu.
The above content is the cultivation method and management skills of peas, I hope to help you! Warm reminder: Autumn cultivation should choose early-maturing varieties, sowing in early September, harvested before the cold wave comes in late November. In the autumn, the growth period is also short. It can be raised in the shade shelter in the summer, and covered with plastic film in the winter to prolong the growth period.
