Kidney beans are suitable for planting in temperate zones and tropical high-altitude areas. They are relatively cold-tolerant, prefer light, and are cross-pollination and short-day crops. Kidney beans are native to Mexico and Argentina in the Americas. my country only began to introduce and cultivate them at the end of the 16th century. After artificial cultivation and domestication, it has adapted to the cool and humid plateau areas. The countries with larger planting areas are Argentina, the United States, and Mexico in the Americas, the United Kingdom in Europe, and China and Japan in Asia. Our country only began to introduce and cultivate it at the end of the 16th century. Nowadays, it is planted in various provinces and regions in China. The provinces with larger areas are Yunnan, Guizhou, Sichuan, etc., while Dali, Lijiang and Lanping in Yunnan have larger planting areas.

Introduction to kidney beans: Phaseolus vulgaris, also known as kidney beans (commonly known as kidney beans or green beans), belongs to the genus Phaseolus in the Fabaceae family. Kidney beans are native to Mexico and Argentina in the Americas. my country only began to introduce and cultivate them at the end of the 16th century.

The main types of kidney beans: The stems of vine beans grow in a left-handed twist, the terminal buds are leaf buds, and the leaf axils of each node can form side vines or inflorescences; the growth period is generally 100 to 120 days; there are many inflorescences, It takes a long time to bloom and set pods, and the yield is high. In its dwarf variant (P.vulgaris var.humilis), the terminal bud forms after the main stem grows for 4 to 8 nodes, and the inflorescence no longer elongates; side branches or inflorescences appear in the leaf axils of each node, and the terminal bud also forms an inflorescence after the side branches grow for several nodes; The growth period is generally 50 to 60 days; there are few inflorescences, few flowers and pods, and low yield. The harvest period is relatively concentrated and suitable for mechanized cultivation. The intermediate type between trailing species and dwarf species is semi-vineing species. In addition, according to the pod structure, they can also be divided into hard-pod beans (the skin inside the pod is developed) and soft-pod beans (the tender pods are thick and have less fiber); according to their uses, they can be divided into pod seeds and grain seeds.
