For peas used in producing pea seedlings, you can choose hemp peas with thick seed coats, small seeds, wrinkled peas or green peas with strong branching, Zhongwan No. 4, Zhongwan No. 6, White jade peas. Green peas have smaller particles, gray-green skin, are resistant to high temperatures, have high vegetable quality, are not prone to fibrosis, are sweet and have a good texture, but their growth rate is slow and their disease resistance is slightly poor. The finished vegetables have smaller compound leaves and stem seedlings. Slightly thinner. Hemp peas have larger particles, and the finished sprouts have extra thick stems, large compound leaves, are beautiful, have strong disease resistance, are not easy to rot, and grow very fast, but are prone to fibrosis and have a slightly poor taste. In principle, the seeds are required to be free of mold, insects, and impurities, have plump grains, uniform size, high purity and clarity, and the germination rate should be above 98%. Try not to buy large peas with yellow, white or green skins. These peas can easily become rotten seeds and seedlings during production.

The selection of seeds for producing pea sprouts is more critical than for producing other sprouts. Especially when producing in summer, be sure to use new seeds harvested that year.

The germination rate of peas not only affects the yield of bean sprouts, but the key point is that peas that do not germinate or germinate slowly will quickly gelatinize and rot under high temperature and high humidity conditions, and even infection will spread. The entire bean sprouts are unable to grow normally.
