White kidney bean is native to Mexico and Argentina in America. It has been domesticated and adapted to the cool and humid plateau areas through artificial cultivation. The countries with large planting areas are Argentina, the United States, Mexico in America, the United Kingdom in Europe, China and Japan in Asia. my country began to introduce and cultivate it at the end of the 16th century. Now it is planted in all provinces and regions of China, with the provinces with larger planting areas being Yunnan, Guizhou, Sichuan, etc., while Dali, Lijiang and Lanping in Yunnan have larger planting areas.

Kidney Bean Preservation

(1) Storage rack method: In the open air, in a shed or indoors, use wooden poles or steel to build a storage rack. Bundle the harvested and dried green onions into bundles of 7 to 10 kg and stack them on the rack in order, leaving gaps in the middle for ventilation to prevent rotting. For outdoor storage, cover with plastic film to prevent rain. Open the bundles regularly for inspection during storage, and remove plants that have heated up or deteriorated in time.

(2) Ground storage method: Spread 3-4 cm thick sand on a flat ground in a leeward location, and place the dried green onions densely on the sand, with the roots facing downward, 1-1.5 meters wide. After stacking, build up 15 cm high sand around the roots of the green onions. Cover with straw mats and plastic film to prevent rain.

(3) Trench storage method: Dig a shallow trench 20-30 cm deep and 50-70 cm wide in a cool and ventilated place. Bundle the selected and dried green onions into bundles of about 10 kg. After the trench is filled with enough water, plant the green onions in bundles into the trench, cover the white part of the green onion with soil, and surround it with corn stalks to facilitate ventilation and heat dissipation. Cover with straw mats or corn stalks before the temperature drops.

(4) Storage in a cellar After harvesting, dry the green onions for several days, bundle them into bundles of about 10 kg, and place them upright in a dry, sunny, and rain-proof place to dry. When the temperature drops below 0°C, store them in a cellar. Keep the temperature in the cellar at 0°C and pay attention to heat and moisture protection.

(5) Cold storage method: Bundle green onions without diseases, insect pests or injuries into bundles of about 10 kg, put them into boxes or baskets, and store them in cold storage. The temperature in the storage is maintained at 0-1°C and the relative humidity is 80%-85%. During storage, regular inspections should be carried out to remove rotten and spoiled green onions in a timely manner.

(6) Slightly frozen storage method: Dig a shallow trench 10-20 cm deep and 1-2 m wide on the north side of the east-west wall. Bundle the dried green onions into bundles of 7-10 kg and store them vertically in the trench. In the early stage of storage, the top of the green onion bundles is left open and turned over once a week to dry all the green onion leaves. When the weather is cold and the green onion whites are slightly frozen, add soil to the green onions and cover the top with straw mats.
