Broad bean is an annual plant, which can be eaten as a vegetable and is deeply loved by people for its rich nutritional value and delicious taste. Improving the quality and yield of broad beans is an important measure for local farmers to increase production and income. Here's how to grow broad beans.

First, variety selection

Choosing a good variety of broad beans is the first step to improve the planting technology of broad beans, and the influence of planting conditions should be considered. When selecting broad bean varieties, we should comprehensively consider local climate characteristics, altitude and other environmental factors, and adjust measures to local conditions. Varieties with strong disease resistance and large particles can be selected to reduce the occurrence of broad bean diseases. The main broad bean varieties suitable for high-yield cultivation are Fengdou 6, Fengdou 7, Fengdou 1 1 and so on.

Second, the correct planting

Mechanized precision sowing and traction on-demand sowing can be used, usually in early July. The sowing amount per 700 square meters is controlled at 30-40 kg, and the row spacing is 20 cm × 25 cm. The depth of seeds sown in the soil is about 4 cm when sowing a single plant as required. Proper depth can promote the development of plant roots, be beneficial to the absorption of nutrients, and resist wind and collapse. Note that 5000 plants can be planted per mu.

Third, fertilization technology

In the process of broad bean planting, reasonable fertilization is the key factor to ensure the normal growth of broad bean. The yield per mu of broad beans can generally reach 400 kg. Rhizobia, as a leguminous plant, can fix nitrogen in soil and absorb 30% nitrogen in soil. Therefore, the part of nitrogen fertilizer can be reduced appropriately. In the actual fertilization process, exogenous nitrogen fertilizer provides 70% nutrients for crops to avoid inhibiting the growth of broad beans. Effective nitrogen fertilizer, phosphorus fertilizer, potassium fertilizer, etc. In addition, a certain amount of farm manure should be applied. About 1000 kg of agricultural fertilizer is needed per mu of broad beans. In the process of broad bean production, the demand for other nutrients is also relatively high. Theoretically, 4 kg of potassium sulfate, 26 kg of urea and 25 kg of calcium are applied per mu to ensure high yield of broad beans and full utilization of nutrients. Of course, fertilization is not as much as possible, but needs to be combined with the actual growth of local crops and soil nutrients.

The above is an introduction to the planting methods of broad beans for your reference and study, hoping to help you. Many shortcomings, please understand.
