Carob is an annual climbing plant of the genus Cowpea in the Fabaceae family.

Bean (Vigna unguiculata), also called cowpea, is a vegetable abundant in summer. The pods droop and swell to some extent when tender. The tender pods are used as vegetables. Depending on the color of the pods, the varieties can be roughly divided into four types: white-skinned, green-skinned, red-skinned and spotted. The seeds are kidney-shaped and 8-12 mm long; the flowers, Fruiting period is summer.

It is a cultivated species of cowpea that can form long pods and is an annual twining herbaceous plant. Also known as carob beans, long carob beans, belt beans, and skirt beans. Contains various vitamins and minerals, etc. Tender bean pods have thick flesh and are crispy and tender when stir-fried. They can also be blanched and eaten cold or pickled. The pods are long and tube-shaped, crisp and soft. There are two common types: white beans and green beans.

When purchasing beans, it is generally better to choose beans that are uniform in thickness, bright in color, transparent and shiny, and full of seeds, while beans with cracks, skin wrinkles, too thin strings without seeds, and insect marks on the skin are better. It is not advisable to buy green beans. Beans are very nutritious and are the meat among vegetables.

Growing environment of green beans

Beans are heat-resistant vegetables that can withstand high temperatures but cannot tolerate frost. Seeds germinate faster at 25~35℃. When the temperature decreases, they germinate slowly and the germination rate decreases. The lowest temperature is 10~12℃. After sowing, seedlings emerge quickly at 30~35℃. After the vines are drawn, they grow well at 20~25℃ and can still grow at around 35℃.

The suitable temperature for the flowering and pod setting period is 25~28°C. Pods can still be formed above 35°C. Growth is slow when the temperature is around 15°C. If the temperature is below 10°C for a long time, the growth will be inhibited. When it is close to 0°C Plants freeze to death. However, if the temperature is higher than 35°C or lower than 15°C, not only will the plants decline prematurely, a large number of flowers and pods will fall, but the pods will also become shorter or deformed, and the quality will deteriorate.
