When is broad bean planted? where is the origin of broad bean?

I believe everyone has eaten broad beans, so when should broad beans be planted? Where is the producing area of broad beans? I believe that no one has ever been curious about this, and no one has ever understood it, so in order to enable you to better understand broad beans, I have sorted out the following information for you to introduce what broad beans are for reference only.

When will broad beans be planted

The planting time of broad bean is also different in different areas, and the planting methods are also different. the time of planting winter broad bean in rice fields in the south should be sown after rice harvest, and the sowing time along the Yangtze River is between Cold Dew and Frosts Descent. South China double-cropping rice area before and after Lesser Snow. The north usually takes the time to sow seeds after the spring thaw.

Where is the producing area of broad bean?

Broad bean can be planted in most provinces in China, mainly sowing in autumn and winter in the south of the Yangtze River and early spring sowing in the north of the Yangtze River. In addition to Shandong, Hainan and northeast provinces rarely grow broad beans, the other provinces (autonomous regions, municipalities directly under the Central Government) all grow broad beans. Among them, Yunnan, Sichuan, Hubei and Jiangsu provinces in autumn sowing areas have more planting area and output, accounting for 85%, and spring sowing areas in Gansu, Qinghai, Hebei and Inner Mongolia account for 15%. Yunnan is the province with the largest planting area of broad bean, accounting for 23.7% of the country. It is planted at about 350000 hectares all the year round, mainly sowing in autumn.

Sowing method of broad bean

1. Fine soil preparation: broad bean is a deep root crop. Fine soil preparation before sowing can make the soil soft, which is beneficial to root expansion and nodule formation.

2. Rhizobium inoculation: inoculation with rhizobium before sowing can increase the yield. Inoculation methods include soil inoculation and seed inoculation. Soil inoculation is to transport about 50 kg of topsoil from the ground where broad beans were planted last year and spread it evenly in the sowing ditch when sowing. Seed inoculation is to dilute the rhizobium powder with water when sowing, and then mix it well with the seeds to sow. And cover the soil with sowing to prevent the rhizobia from being killed by direct sunlight.

3. Sowing time: broad bean planting time is also different in different areas, and planting methods are also different. the time of planting winter broad bean in paddy fields in the south should be sown after rice harvest, and the sowing time along the Yangtze River is between Cold Dew and Frosts Descent. South China double-cropping rice areas before and after Lesser Snow, the north generally seize the time to sow seeds after spring thaw.

4. Sowing density: the sowing density should be determined according to the cultivation purpose, variety characteristics, soil fertility and fertilization level. Generally, the seeds collected should be thinner than those with green fodder or green manure, and the varieties with long growth period, high plant height and more branches are shorter than the growth period. The short plants should be thinner, and those with low soil fertility and low fertilization level should be denser. Usually, the basic seedlings of large seeds are 1 to 13000 per mu, and the small seeds are about 24000 per mu. The sowing rate is 10 to 12 kilograms per mu.

Field management of broad bean

The main results are as follows: 1. Seedling management measures: in the seedling stage, the strong seedlings can be achieved by controlling water or irrigation according to the seedling situation, so that the seedlings are uniform, uniform and strong. Glue-stained mud bean fields should be covered with grass to keep warm and moisturize in time after sowing.

2. Medium-term management measures: do a good job in the prediction and forecast of diseases and insect pests, timely control the harm of diseases, insect pests and rats, and do a good job in water management. The seedlings were pruned in the field, and the thin and diseased plants were pulled out to ensure the healthy growth of the population.

3. Management measures in the later stage: ensure the demand for moisture during the filling period, keep the soil water content at 20% 25%, less than 18% 20%, and must be irrigated immediately; high-yield fields and late-maturing fields should be topped and cored at the final flower tip stage, which is conducive to ventilation and light transmission, increase grain weight and promote precocity.

4. Precautions: avoid continuous cropping of broad bean, continuous cropping makes the plant sterile, the number of rhizobium is less, the activity is low, the pods are less, and the disease is more, so the rotation of planting broad bean will be carried out for at least 3 years. Broad bean is adapted to slightly sticky and moist soil, but it is better to be cultivated on deep, fertile clay loam or sandy loam. The tender pods of broad beans can be harvested at the right time, and they can be harvested from the bottom up for about 7-10 days each time. The mature seeds can be harvested when the leaves of broad beans wither and fall, and when the middle and lower pods are fully mature, they can be dried and threshed for storage.

In fact, although broad bean used to grow there, but now due to the development of science and technology, it is no longer subject to geographical restrictions. It can be cultivated in various places and can be planted at any time. You can also eat fresh broad beans all the year round.
