What are the seed selection and seedling-raising methods for snow peas?

Snow peas, also known as peas, are one of the vegetables people commonly eat. The tender pods of snow peas are emerald green in color and rich in a variety of vitamins and minerals, making them highly nutritious and in great demand on the market, so many farmers grow them. So how do you select seeds for snow peas? What seedling-raising methods are there? Let's take a look together below.

1. How do you select seeds for snow peas?

When selecting seeds for snow peas, you must be meticulous, requiring characteristics such as large, plump grains and high quality. After sowing, such seeds can reduce the threat of diseases and pests and also improve the uniformity of sowing. Put the seeds into salt water; rejected seeds will float on the surface, so you can pick them out, while the better, heavier seeds will sink to the bottom, and such seeds are very suitable for sowing.

As for varieties, the snow pea varieties currently grown more widely include three types: pea-grain snow peas, pod snow peas and shoot snow peas. Everyone should choose suitable varieties according to the different geographical conditions and growing conditions of different regions. For example, in the Shanghai area, pea-grain snow peas are generally sown more, mainly the small green pod variety, with a seeding rate of 5-7.5 kg per mu.

1. Seed treatment

First, put the selected seeds in the sun to dry for 3-5 days. The purpose of sun-drying the seeds is to sterilize and kill insects and to increase the germination rate of the seeds. After sun-drying is complete, soak the seeds in cold water for two hours. Once their seed coats have swollen, take them out, then wrap them in a towel or gauze and place them in a spot where the normal temperature reaches about 20 degrees to germinate. After this series of treatment operations, you can proceed with the subsequent sowing and seedling-raising work.

2. Sowing and seedling raising

The sowing time is generally March-April each year. In the north, it is planted in early spring and autumn, while in the middle and lower reaches of the Yangtze River and areas to the south, it can be sown in all four seasons, but autumn and winter are best, mostly sown from late September to early November. Usually direct sowing is used; after watering thoroughly, sow 2 to 3 seeds per hole, cover with about 3 cm of soil, and then sprinkle a thin layer of plant ash on the soil surface. The suitable temperature for growth during the seedling stage is 14-22 degrees C, and it can endure low temperatures of -4 to 5 degrees C.

If the leaves do not wilt in the morning and evening, there is no need to water. About 10 days after germination, apply 1 application of dilute decomposed organic fertilizer. After 2 weeks of germination, when 1 to 2 pairs of true leaves have grown, transplant and set out, with 3 to 5 plants per pot, and sufficient decomposed organic fertilizer should be applied to the soil as a base fertilizer.

3. Management after seedling raising

During the seedling growth period, the soil is required to remain moist but not waterlogged. Fertilization should be based mainly on base fertilizer, with more phosphorus and potassium fertilizer applied, and basically no nitrogen fertilizer needs to be applied. When the plant height is 30-40 cm, insert several bamboo poles into the potting soil to guide the snow pea seedlings to climb, and be careful to make the stems and leaves distribute evenly.

The above is an introduction to snow peas. Raising snow pea seedlings is not difficult; as long as you choose suitable varieties and manage them scientifically, you can achieve a good yield.
