During the sowing period, the peas are not heat-resistant, and they can only be planted in spring and summer in the northeast region, and harvested in summer and autumn. If you use early maturing dwarf or half-vegetable early-maturing varieties, you can plant autumn cabbage and Chinese cabbage in autumn. In the early spring, the soil can be sown after being frozen, usually in the first ten days of dry seeding, and harvested in the middle and late June, and the harvest will be completed before the summer. Due to the short growth period, early maturing, dwarf or semi-vine varieties should be used, and dense planting should be carried out. It is also possible to use early, middle and late maturing varieties. From the beginning of April to the beginning of May, the sowing can be carried out in stages. extend.
Site preparation and sowing
The sooner spring is broadcast, the more beneficial it is to increase production. However, in the case of early sowing, especially the early-wound varieties of wrinkles, due to the low ground temperature, if the soil is too wet, it is prone to rotten species. Therefore, spring sowing should be dry seed, not soaking seeds. In the case of soil drought during spring sowing, it is necessary to first irrigate the water and then plant it.
Peas are the most common crop, suitable for interplanting in wheat fields and potato fields. Before planting, it is necessary to deepen the soil and apply appropriate amount of simmered manure to promote the peas to be unearthed, the seedlings are strong, and the resistance to stress is enhanced. The peas can be grown for 1-2 days before sowing, which can increase the emergence rate. Dwarf species are suitable for striping, with a line spacing of 60 cm and a spacing of 8-10 cm. The vine variety is suitable for hole sowing, the row spacing is 60 cm, the plant spacing is 15-20 cm, 2-4 capsules per hole, and the amount of seeds per hectare is 75-90 kg.
Field management
After the spring peas emerged, they should be ploughed several times in advance to increase the ground temperature, promote root development and make the leaves thick, and stop cultivating after the bud stage. In order to promote the growth of branches and leaves, the topdressing stage begins to topdress and water. In the spring drought, the seedling period can be ploughed 2-3 times, fertilized 1-2 times, and irrigated 2-3 times. The last time the cultivating is combined with the soil. It is also necessary to strengthen irrigation, topdressing, and promote growth and development during the period of flowering and flowering, so that it has a longer flowering and pod-forming period before the arrival of summer, in order to improve production. Pea stems and vines are easy to fall. Any cultivated long vine and medium vine varieties should pay attention to the scaffold when the plant height is about 30 cm, making it ventilated and easy to pod.

Plant extracts refer to substances extracted or processed from plants (all or a part of plants) using appropriate solvents or methods, and can be used in the pharmaceutical industry, food industry, daily chemical industry and other industries.
There is a conceptual overlap between plant extracts and herbal extracts. The raw materials of plant extracts in my country are mainly derived from Chinese herbal medicines, so domestic plant extracts can also be called Chinese medicine extracts to some extent.
