Southwest and Yangtze River Basin and other provinces and districts of fava beans in the fall sowing, usually in early October to early November sowing. Northwest and other provinces and regions of broad beans are sown in the spring, harvested in the fall of the year. The general sowing is in mid-late March to early April.

Fava bean planting method

1, variety selection

The choice of planting varieties is based on the planting purpose to determine, if planted as a vegetable green beans should be selected as a large grain seed, each 100 grains weighing more than 120 grams. If used as fodder and green manure to choose a strong branching, even rapid, high yield of fresh grass small grain species, each 100 grains weighing less than 70 grams.

2, inoculation rhizobium

To plant good beans before sowing should be inoculated with rhizobium, especially not planted fava bean plots, inoculated with rhizobium can be early tumors, more tumors, and improve the yield of fava beans. There are three ways to inoculate rhizobium, one is to use the topsoil of planted fava beans, 150 kilograms per mu. The second is to use 200 grams of rhizobacteria and water mixed with 20 kilograms of broad bean seeds. The third is to use rhizobial fertilizer, 500 grams per mu with fine soil mixed evenly spread in the seeding nest.

3, land preparation

Most of the planting of fava beans and garlic using rice harvested paddy field planting, no-tillage direct seeding cultivation after rice harvest, paddy field after rice harvest without plowing, direct sowing. One is in the rice waxing and maturing period on the open back ditch, side ditch, cross ditch for drainage, sowing before the opening of the compartments to straighten the ground, compartment width of 1.7-2 meters, ditch width of 33 centimeters, ditch depth of 25 centimeters, and then finely leveled.

4, sowing

Autumn sowing optimal sowing period for 15-20 days after the rice harvest, spring sowing in mid-late March to early April sowing. Southwest and Yangtze River Basin provinces and districts broad bean sowing is the implementation of prying nest sowing rice stakes beans, both early sowing broad beans, but also the use of rice root and stem rot as fertilizer and seedling neat. General large grain seed per mu planting 1-1.5 million plants, medium grain seed 1.4-1.7 thousand plants, small grain seed 20,000 or so, sowing nest spacing 27-30 cm, row spacing of 40-50 cm, each nest sowing 2-3 seeds. There are fewer large-grain seeds and more small-grain seeds.

5, fertilization management

Fava beans can use rhizobium to fix the nitrogen in the air, providing some nitrogen for plant growth, but the beans still need fertilizer, generally 500 kg of farmyard manure, 25 kg of phosphorus fertilizer per mu of bottom fertilizer. Seedling in the rhizobacteria did not respond to the perfect before, can be combined with drought, 500 kg of clear manure per mu, the first flowering and podding period mu with 15 kg of composite fertilizer, urea 10 kg of soaking water watering each 1 time.

6, harvest, dry seed production is harvested in the broad bean plant leaves yellow and dry, plant stalk color yellow-green water loss.
