What is the method of growing pea seedlings? How to choose the seed?

Pea seedlings are a kind of vegetables, which are the tender stems and leaves of peas, also known as asparagus seedlings, asparagus, pea tips, etc., which are rich in nutrition and contain a variety of essential amino acids for the human body, so what is the planting method of pea seedlings? How to choose the seed?

First, how to choose pea seedlings?

1. Seed selection

Peas that produce pea seedlings should not choose large peas with yellow or green skin, which are easy to rot in the production of these peas. Green peas or sesame peas with thick seed coat and small grains should be selected. the pea seedlings produced by these peas have thick stems and leaves, fast growth and strong disease resistance. The principle requires that the seed should be full, high purity and purity, and the germination rate should be more than 95%.

2. Deal with

Wash the seeds with 20-30 ℃ warm water for 2-3 times to remove impurities and broken beans.

3. Pickled beans

First blanch the peas in 55 ℃ of warm water for 5 minutes, then stir carefully. Then soak in 25-28 ℃ water of 2-3 times the seed weight for about 18-24 hours (short time in summer and autumn, long time in winter and early spring). Wait until the seeds are fully expanded, the wrinkles disappear, and the bud roots can be clearly seen in the transparent seed coat after soaking.

Second, what is the method of planting pea seedlings?

1. Planting season

From March to April (spring in the north should be early and thawing can begin; four seasons in the middle and lower reaches of the Yangtze River and the south can be sown, but autumn and winter are the best, and most of them are sown from late September to early November).

2. Sowing seeds

After soaking the seeds, rub the mucus off the seed coat, drain the excess water, and then spread the seeds evenly on a plastic plate (the plastic plate should first be sterilized with rotten fungus and covered with newspaper or toilet paper). 6 plates in a pile, spray water twice a day (it is better to have no water in the seedling plate after spraying moisture). At the same time of spraying water, change the position of the seedling plate up and down, around and around. After 48 hours, the pea seedlings can grow to 2-3 cm, at this time, the seedling tray can be placed on the ground, or moved to the cultivation rack for production management.

3. Daily management

(1) Light

During the growth of pea seedlings, we should pay attention to the light is not too strong, lest cellulose is formed prematurely, affecting the quality. But the light should not be too weak, lest the pea seedlings grow thin.

(2) watering

During the growth period, spray water 2-3 times a day, pay attention to rainy weather or indoor temperature is low, high temperature or indoor humidity is small spray. In addition, we should also pay attention to the necessary ventilation to avoid rotten seedlings.

(3) temperature

The suitable temperature for seedling growth was 14 ~ 22 ℃, which could tolerate a low temperature of 4 ~ 5 ℃, and no watering was needed if the leaves were not wilted in the early and late stages.

(4) fertilization

The rare and mature organic fertilizer can be applied once after germination for about 10 days. After 2 weeks of germination, 1-2 pairs of true leaves were transplanted and planted, 3-5 plants in each pot, and enough mature organic fertilizer should be applied as base fertilizer in the soil.

4. Harvest

When collecting pea seedlings, you must be careful not to pull it up by the roots, but to leave it with a heel of 2 to 3 centimeters, and then spray water like these roots 2 or 3 times a day, so that you can wait for 3 to 5 days. You can collect fresh pea seedlings again. Generally, it can be collected 2 or 3 times according to this method.
