1, planting time: peas in areas north of the Yangtze River are generally sown in March-April; areas south of the Yangtze River are generally sown at the end of September or in early October to November. 2, planting methods: the soil to deep soil, soil salinity is light, medium fertility of the land is preferred, and then deep plowing; seeds to particles of large and full of seeds is preferred and seed germination treatment, the Seeds are soaked and then sown; before sowing to apply fully heated stable manure, compost and a certain amount of phosphorus and potash fertilizer, sowing using the spot sowing method, watering and covering a thin layer of soil; in the growth process of peas to do a good job of water and fertilizer management, as well as pest control and other work.

A pea planting time and method

1, planting time

Pea planting time varies depending on the climate of each place, generally north of the Yangtze River is known as the spring sowing area, sown in March-April, this period of time, the seeds are more prone to germination, conducive to the growth of the south of the Yangtze River is known as the fall sowing area in late September or early October to November sowing, the seed is more likely to germinate, conducive to the growth of the Yangtze River is known as the autumn sowing area in late September or early October to November sowing. Early October to November sowing, these two time periods the climate is relatively mild, suitable for growth.

2, planting methods

(1) Selection of land preparation

peas on the soil requirements are not high, the soil layer is deep, the soil salinity is relatively light, moderate fertility of the land can be planted. After selecting a good land, deep plowing is carried out to ensure the permeability and drainage of the soil, to avoid the occurrence of root rot phenomenon.

(2) Selection of seed soaking

Selection of pea seeds, generally to choose the particles of large and full of seeds is good, at the same time to ensure that the quality of the seeds, once found that there are pests and diseases of the seeds should try to pick out, otherwise it will not only affect the germination rate, but also contaminate the soil. Seeds selected to be put into the salt water soaking, fishing out the seeds floating in the water and throw away, soak overnight to be the seeds to absorb enough water after taking out can be sown.

(3) fertilizer sowing

The field before sowing should be applied to the fully heated stable manure, compost and a certain amount of phosphorus, potash, in which the effect of phosphorus fertilizer yield increase is obvious. When the seeds appear to dew white phenomenon can be planted into the soil, the use of spot sowing method, row spacing 10-20 cm, 5 cm spacing between plants in the row, each hole sowing 2-6 seeds, followed by watering thoroughly, and covered with a thin layer of soil, press the solid and wait for germination. When the temperature is low, you can also cover the film on top to keep warm and moisturize, and when the seeds sprout in 2-3 days, the film can be removed.

(4) Fertilizer management

During the growth of peas, it is necessary to apply enough compound fertilizer and agricultural fertilizers to ensure the growth of peas. Applying urea and organic fertilizer during flowering and podding can promote podding and fruiting. In the later stages of growth, fertilize extra-radically with a mixture of 0.5% urea solution and 0.2% potassium dihydrogen phosphate. It is also important to maintain adequate water, especially in the summer, not only to supply water to the plant, but also to lower the temperature of the ground to avoid sun or heat death of the plant.

(5) pest control

Common diseases of peas are root rot, brown spot, powdery mildew, etc., and common insect pests are black fly, leaf miner fly, etc.. Pests and diseases must be prevented in advance, generally available imidacloprid, chlorothalonil and other sprays to prevent and control germs and insects coming. In the pea throughout the growth process should be fine management plots, and the scientific use of pharmaceutical control of pests and diseases.

Second, peas are autoflowering or heteroflowering

1, peas are autoflowering pollinators. In the pea flower butterfly-shaped corolla, there is a pair of petals always tightly wrapped around the stamen and pistil, this structure determines the pea's pollination mode is self-pollination, closed flower fertilization plants. Other self-pollinated plants are barley, wheat, soybeans, beans, henna and so on.

2, pollination has two ways of autoflowering and xenogamous pollination, in which the mature pollen grains of plants are transmitted to the stigma of the same flower, and can be normally fertilized by the process of fruiting is called autoflowering pollination; pollen with the help of external forces, from the stamens of a flower to another flower of the pistil on the stigma of the process is called xenogamous pollination, this is a more common phenomenon in nature.
