There are several varieties of peas, some pods are flat and large, we call them vegetable peas, and some peas have flat and small pods and mature late, we call them local peas. In addition to this, peas are also divided into early-maturing types. (1) pea seed selection and processing: There are many varieties of peas, should be selected with a high seedling yield, fast growth rate, quality and tender, thousand grain weight of about 150 grams of small smooth seed is good. Pea seed life span is generally 2~3 years, germination rate of low aged seeds can not be used for pea sprout production.

Planting pea seedlings, the soil requirements are not strict, but in order to improve yield and quality, you should choose a deep layer of soil, soil loose and fertile, rich in organic matter neutral soil, requiring soil pH in 6-7.5, stubble to wheat, potatoes, as well as non-leguminous vegetables as well, strictly avoid continuous crop soaking seed germination. First of all, the moldy, broken, immature seeds out, after screening out the seeds can be soaked. Seed soaking time in summer is about 8 hours, winter soaking time should be longer, about 10 hours or more. Soak the seeds during the water change 2-3 times.

Seedling promotion. The temperature during seedling promotion should be controlled at 18~25℃. Too high a temperature will cause the sprouts to grow in vain. Sprouts are too slender, easy to cause late collapse, eating taste will also be seriously deteriorated. At the same time, the seedlings are evenly wetted with a spray bottle 1~2 times a day to maintain the humidity of the paper. Then on the ridge nest planting, nest depth of 5 a 8 cm, row spacing of 40 a 50 cm plants, depending on the situation, and then in a good nest into the 3 a 4 pea seeds, and finally a handful of ash fertilizer or composted farm compost on top of the seeds.

Conduct the selection of pea seedling seeds, choose the grain full and healthy is appropriate; the second point: the bowl of pea seedlings soaked in water for more than a day, eliminating the bad seeds; the third point: the emergence of sprouting points of the bowl of pea seedlings placed in seedling pots for maintenance, placed in a shady environment, waiting for it to germinate place requirements: the production of pea seedlings, can be used in unused houses, closed balconies, winter warming greenhouses. Temperature 18-23 ℃, humidity about 80%. Light requirements weak light.
