Peas are one of the most important food crops grown in our drylands in the north and south of the country, as well as the ideal inter-cropping crop in agricultural production. The production of peas in our country is more affected by adverse conditions such as winter frost, spring drought, etc. In addition to the main factors affecting the production of peas such as pollinosis, rusty disease, root decay, leaf flies and aphids. With the restructuring of the industry, the growth of peas and the use of their products have become more diversified and economic efficiency has increased. In order to guide the cultivation of peas in various areas and to promote the production of peas, the ministry of agriculture and rural development, in collaboration with the national centre for agricultural technology promotion, has developed a technical opinion on peas production for 2022。
I. Selection of progeny
The selection of varieties is based on the use of peas. For the purpose of harvesting dried seed particles, semi-leaf-free strain varieties should be chosen; for the purpose of harvesting fresh seed seeds, varieties with a high soluble sugar content and a hard-candle type should be selected; for the purpose of harvesting fresh seed seeds, a soft-basket type should be chosen; and for the purpose of harvesting fresh eating leaves, late-cooked varieties with a long-lived and strong seeding season should be preferred. To the extent possible, seeding should be conducted live in dry lands free of cropping, in order to ensure that the impacts of drought, frost and other adverse factors on peas are effectively avoided. The production of fresh peas in the south can be facilitated by the use of artificial strangulation to attract chickens, which can increase productivity。
Ii. Corrective secretariat
(a) 8-10 kg of acreage of short-lived varieties, 40-50 cm range, double/single-carved troughs, 13-15 cm range and an acre density of 350,000-40,000 at the time of single planting of dry peas in the autumn; half-cranium or chicken species, 6-7 kg acreage, 40-50 cm line range, double/single-particle trough, 20,000-30,000 acre density. In order to allow many harvests and save production costs during the autumn season, acreages of short/square species were broadcast from 5 to 8 kg, 10 to 15 cm, 80 to 100 cm in rows, double or single grains, and a density of 150 to 20,000 acres. In addition, the spacing of seeding lines may be adjusted to the previous crop spacing. The increase in density can be achieved by reducing the distance between the spring and the autumn bean density, which is about one-fold higher, due to a rapid recovery in temperature and smaller branches。
Iii. Scientific water management
Ensuring that whole seedlings are a key factor in the high yields of peas. Peas are extremely resistant to flooding, and the cultivation of peas in drylands recommends water conservation, such as spraying or drip irrigation, to be supplemented with moisture. (b) one water supply in the field at a moisture content of less than 20 per cent, based on soil conditions; if water is recharged by flooding, it should be stopped immediately after the water has passed through the compartment to ensure that the ditches are free from flooding. In less fertile plots, 20 kg of phosphorus and 10 kg of urea per acre are followed up once each time during seeding and flowering periods, and leaf-leaf fats, such as one dose of potassium phosphate, are sprayed during flowering periods to stabilize production。
Peas produced by fresh foods require the timely removal of some high-level and slow-growing branches and abnormally morphological branches to ensure their normal and high-quality growth. The spare branch is removed from the plant with scissors and three to four branches are retained in the main branch。
Iv. Integrated pest and grass control
Insects and diseases are based on integrated prevention, with appropriate reduction of field moisture and increased air flow to reduce the incidence of disease. In high-prevalence areas such as powdered, rusty, red spots, the use of broad spectrum microbicides such as triazone and enzymes is sprayed every 5-7 days, three times continuously to prevent disease effects. The control of pests is based on physical measures supported by chemical control; 50-60 tablets per acre have been planted with blue, yellow viscos and insect lanterns in the fields; chemical control should be introduced in a timely manner on the fields where pests such as aphids and tectonic flies are already present; and chemical control should be discontinued in areas where the production of fresh aphids is predominant, some 20 days before the marketing of fresh aphids. Herbicides are closed to weeding before spraying in peas within three days of sowing, and weeding is no longer appropriate at a later stage, especially if any form of weeding is not repeated after the start-up period。
V. Electronic access
Peas products are of a variety of types, and for different uses, harvest and scientific storage are classified for transport to ensure product quality. When producing dutch peas, sweet peas and peas, harvest when the calves are fully grown up and the drums have not yet started; when producing peas seed, harvest when the plume is full and the seed seed is yellow; and when producing peas when the beans are so hot, they are harvested in a timely manner before flowering, and are grown by hand, and the peas stem is more vulnerable, they should as far as possible avoid plant damage and be transported to the ventilation shade in time for harvest; when the peas dry seed is produced, 80 per cent of the aluminum seed is harvested when it is yellow, and when the fields are wet and not fragile, they are taken off in a timely manner for a period of two to three days, in a bag of 20 to 25 kilograms of nylon fabric, and transferred to the closed room for the fumigation of phosphorous aluminium for 5 to 7 days to prevent the appearance of the bean elephant。
