Seedling raising technique of pea

Pea is a kind of legume plant that we are familiar with, and it is also a dual-use crop of vegetables and food. it is a vegetable with high economic benefits and broad prospects for development. So how do peas grow seedlings with seeds? Let's take a look at the detailed introduction with the editor.

1. Select the place

Pea seedlings have deep roots and strong drought tolerance, but not moisture tolerance, so they choose neutral or slightly alkaline soil which has not planted fruit and legume crops for 3-4 years, high terrain, convenient drainage and irrigation, loose and fertile neutral or slightly alkaline soil. When planting, clean the weeds on the ground, prepare the soil, rake fine and level it, and rake the soil loose in advance, which is beneficial to seed germination.

2. Sowing time

Pea seedlings are cold-resistant and not heat-resistant, and the most suitable temperature for seeds is 18-20 degrees, so they can be cultivated in other seasons except for the high temperature period in summer. In the south, spring sowing and autumn sowing are generally adopted, spring sowing is usually carried out from February to March, autumn sowing is usually carried out from September to October, and in warm areas, sowing can be carried out in 10 months or 1 year of the following year.

3. Sowing seeds

Base fertilizer should be applied before sowing. Generally, 1500 kg of rotten farm manure, 30 kg of calcium superphosphate and 10 kg of potassium chloride should be applied per mu. Sowing is using the method of on-demand sowing, opening holes on the box surface according to the row spacing of 40 × 15 cm, sowing 5-6 grains per hole, generally 10-12 kg per mu. After sowing, the soil is covered and watered to keep the soil moist. Seedlings can emerge soon when the temperature is suitable, and transplant when the seedlings grow to 8-10 cm and 2-4 true leaves.

4. Strengthen the management

Topdressing should be done twice after transplanting, mainly with quick-acting nitrogen fertilizer, and each time it should be diluted with water to avoid damage to seedlings caused by excessive concentration of fertilizer. Pea seedlings and waterlogging, so in time after the rain to clear the ditch drainage, so as to avoid retting roots dead seedlings, in the long drought is to water, to keep the soil moist. It is necessary to properly cultivate the seedlings at the seedling stage, promote the growth of seedlings, cultivate the soil properly after rain and fertilization, and pay attention to weeding and introducing vines. We should pay attention to the prevention and control of diseases and insect pests. The common diseases are powdery mildew, yellow top disease and yellow top disease, which can be controlled by methyl thiophanate, carbendazim and chlorothalonil.
