How to select peas? What are the breeding methods?

Pea is one of the main varieties of legumes in China, and it is also a very common legume vegetable on the dinner table of ordinary people. Peas have a lot of practices, and they also have dietotherapy values such as invigorating the body to quench thirst, cleaning up the intestines and stomach, and diuresis. The key is that they have a long history of cultivation. Basically, peas can be seen in vegetable planting parks. So how to choose peas? What are the methods of raising seedlings? Let's get to know it.

How to choose peas?

Seed selection must be fine, and it is required to have the characteristics of large, full and high quality. after sowing, the threat of diseases and insect pests can be reduced, and the neatness of sowing can be improved. Put the seeds in salt water, the unqualified seeds will float on the surface of the water, so that they can be picked out, while the better quality and heavier seeds will sink to the bottom of the water, which is very suitable for sowing.

In addition, there are three types of pea varieties cultivated at present: pea for pea, pea for pod and pea for seedling. We should choose suitable varieties according to different geographical conditions and planting conditions in different regions. For example, there are more peas used for sowing peas in Shanghai, mainly small green pod varieties, with a seed consumption of 5-7.5 kg per mu.

The method of raising pea seedlings

1. Seed treatment

First of all, put the selected seeds in the sun for 3-5 days, the purpose of drying seeds is to kill bacteria and insects and improve the germination rate of seeds. After drying the seeds, soak the seeds in cold water for two hours, wait until their seed coat has swelled, remove them, wrap them in towels or gauze, and put them in a place where the normal temperature reaches about 20 degrees Celsius. After this series of treatment operations, the follow-up work of sowing and raising seedlings can be carried out.

2. Sowing and raising seedlings

The sowing time is generally from March to April every year, planted in the early spring and autumn in the north, and can be sown in four seasons in the middle and lower reaches of the Yangtze River and the south, but it is better in autumn and winter, and most of them are sown from late September to early November. Usually direct seeding, sow 2-3 seeds in each hole after pouring water, cover the soil about 3 cm, and then sprinkle a thin layer of plant ash on the soil surface. The suitable temperature for seedling growth was 14-22 ℃, and it could tolerate-4-5 ℃.

If the leaves do not wilt in the early and late days, they do not need to be watered, and the thin and mature organic fertilizer can be applied once in about 10 days of germination. 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.

3. Post-seedling management

During the seedling growth period, it is required that the soil should be kept moist without stagnant water, the fertilizer should be based on base fertilizer, more phosphorus and potassium fertilizer should be applied, and no nitrogen fertilizer should be applied. When the plant height is 30cm to 40cm, several bamboo poles are inserted into the pot soil to pull the pea seedlings to climb and pay attention to the uniform distribution of stems and leaves.

Generally speaking, peas are delicious and nutritious, and good varieties are easy to manage, so they are very favored by growers. The growth characteristics of peas are relatively distinct, but there will be no mistakes according to the specification process, and the key is to do a good job in seed selection and seedling breeding in the early stage.
