When is the pea on the market?

Pea is a very nutritious vegetable. Pea is different from other vegetables in that it contains antibifuric acid, gibberellin and phytolectin, which have the function of antibacterial, anti-inflammatory and enhancing metabolism. So, when are peas on the market?

When are peas on the market?

Spring-sown peas went on sale in early April and autumn-sown peas went on sale in early October. Its seeds, young pods and young seedlings are edible, and the young pods are light green, with 6-7 seeds per pod.

What are the cultivation techniques of peas?

1. Cultivation system

Avoid continuous cropping of peas. Continuous cropping can cause toxicity to the following peas and aggravate the occurrence of diseases and insect pests, so peas usually have to rotate with other crops. White flower varieties avoid continuous cropping more than purple flower varieties, and their rotation years need to be longer. Peas can also be mixed and intercropped with other crops.

2. Land selection

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 and apply fertilizer

The soil should be loosened several times after sowing, in order to improve the ground temperature to promote root growth, the seedlings are strong, sown in autumn, cultivate the soil once before overwintering, keep warm and prevent freezing, loosen the soil and weed in time after the beginning of spring, and raise the ground temperature. Before flowering, peas were watered with small water to pursue quick-acting nitrogen fertilizer to accelerate plant growth and promote differentiation, and then loosen the soil to preserve soil moisture. When the stem begins to set pods, the amount of water is slightly increased, and phosphorus and potash fertilizer are applied. The soil should always be kept moist during the peak podding period. To ensure the moisture needed for pod development. In the later stage of podding, bean seedlings are ridged and watered less. When the vine plant is 30 cm high, the bracket begins. Peas are harvested in batches and fertilized once for each harvest.

4. Make up the leak and pursue the fertilizer.

Check the seedlings to fill the gaps in time after emergence, and cut weeds in the middle tillage for 1-2 times. Heavy application of topdressing at seedling stage, especially fields with no or less application of base fertilizer, generally apply 5-7.5kg of compound fertilizer or 5kg of urea or 1000 kg of rotten human feces and urine per mu. When the temperature rises in spring and the plant begins to elongate, the long-culm varieties insert small bamboos or branched branches (defoliated) between the rows so that the bean plants can climb and grow. Peas are not resistant to water stains, so we should pay attention to clear ditches and drain water in spring. More nutrients are needed for flowering and podding, with 7.5 kg of urea and 5 kg of ternary compound fertilizer per mu. During the grain filling period, 1% urea and 0.3% potassium dihydrogen phosphate were sprayed twice.

5. Timely harvest

The harvest time is determined according to the way you eat it. Generally, peas are harvested when the seeds are full 15-18 days after flowering, dried peas are harvested when 80% of the pods are withered and yellow, and vegetable peas are harvested 12-14 days after flowering when the young pods are not present. Pea seedlings are harvested at the tip when the seedling height is 18 cm about 30 days after sowing, and those used as fodder are harvested in full bloom, and those used as green manure are pressed in time after pod harvest.

Pea is a semi-cold-tolerant crop, likes temperature and humid climate, is not resistant to dry heat, and is suitable for planting in North China, Northeast, East China and Southwest China.
