The planting methods of peas are divided into soil preparation, fertilization, sowing time, sowing method, field management and harvesting.

1. Land preparation. Peas do not have high requirements for loam soil, as long as the soil layer is deep and the salinity level is low, it is conducive to the survival and growth of seedlings. Spring-sown varieties require deep plowing of the land in autumn to a depth of about 15-25cm. In spring, the rakes are raked and the rubbish is crushed. The varieties planted in autumn and cross-section should be prepared in time according to the actual situation, requiring loose soil and good air permeability.

2. Fertilize. Generally, farmyard manure is mainly used. 500kg-1000kg of decomposed cow manure, sheep manure, chicken manure or compost can be applied before sowing. Phosphorus and potash fertilizers are 30kg and 25kg respectively. The effect of increasing phosphorus fertilizer is more obvious. Because peas contain rhizobia, top dressing is generally not required in the later stages.

3. Sowing time. Spring sowing varieties are usually sown from late February to early March in southern areas, and in April to May in northern areas. Autumn varieties are usually sown in early September. Overwintering varieties are generally sown from late October to mid-November.

4. Sowing method. Varieties for grinding, with a larger planting area, generally sown with columbine, row spacing 10-20cm, plant spacing 3-5cm, single grain sowing, naturally covered with columbine soil, covering soil thickness 3-5cm, sowing rate per mu is about 15-20kg. Rake immediately after sowing.

Vegetable varieties have a relatively small planting area. They are generally sown on demand with a row spacing of 10-20cm and a plant-to-plant spacing of 5cm. 2-6 seeds are sown in each hole. When the soil is moist, cover it with 5-6cm of soil. When the soil is dry, cover it with soil slightly. Thicker, usually 10-15kg per acre, and suppressed in time after sowing.

5. Field management. For varieties used for grinding, cultivate for the first time. When the seedlings are about 5-10cm high, they should be plowed in time to loosen the soil. The seedlings should be shallow and the rows should be deep. The seedlings should be 3-5cm apart and the rows should be 5-10cm. Keep the soil soft to help the roots to take root. Promote healthy growth of seedlings. In the second cultivation, when the seedlings are about 15cm high, the second cultivation is carried out. On the one hand, weeding is carried out, and on the other hand, the soil is loosened. The sides of the seedlings are 5-10cm and the rows are about 15cm.

Generally, cultivating twice is enough. For edible vegetable varieties, tillage to loosen the soil. When the seedlings are about 5-10cm high, tillage and loosen the soil in time. The seedlings should be shallow and the rows should be deep, with 3-5cm beside the seedlings and 5-10cm between the rows. Keeping the soil soft will help the roots to penetrate deeper and promote seedlings. Robust growth. Insert rods and frame: When the seedlings are about 20cm high, insert rods and frames next to the seedlings to guide the climbing frame.

6. Harvest. Milling flour varieties have a short growth period in spring, with low temperatures in the early stage and high temperatures in the later stages. They are harvested around mid-to-late August. The harvest standard is that 70%-80% of the pods are withered and yellow, and the beans are hard. Edible vegetable varieties are generally harvested 12-14 days after flowering when the tender pods have no seeds. Autumn varieties: picked before the cold wave. Overwintering varieties can be harvested from April to May of the following year.

Introduction to Pea

Pea is an annual climbing herb of the Leguminosae family, 0.5-2 meters high. The whole plant is green, smooth and hairless, covered with pink frost. The leaves have 4-6 leaflets, the stipules are heart-shaped, and the lower edge has fine teeth. The leaflets are oval; the flowers are solitary or arranged in several racemes in the leaf axil; the calyx is bell-shaped and the lobes are lanceolate; the corolla has various colors, which vary with the variety, but are mostly white and purple. Ovary hairless, styles flat.

The pods are swollen and oblong; the seeds are round, green, and turn yellow after drying. The flowering period is from June to July, and the fruiting period is from July to September.
