1、 Planting method

1. Soil: there are certain requirements for the growing soil. It is best to use sandy soil with good air permeability, which is also conducive to drainage and rich in sufficient nutrition. In this way, the growth will be more beneficial and the root development will be healthier

2. Seed selection: the selection of varieties is very important. It requires bright color on the appearance, plump head and smooth touch. There are not many tumors on it, nor the influence of diseases and pests. The diameter is kept at about 3cm. Only excellent seeds have a greater chance of survival

3. Sprouting: before planting, sprout yam beans first. Bury them in wet sand, cover them with 3-5cm sand, and put them in an environment of about 25 ℃. When sprouts are observed to emerge from them, they can be sown

4. Sowing: level the land, sow the selected beans in it, cover it with soil, and pour water into it

2、 Planting time

The planting time is also very important. Yam beans can't stand the cold and are easy to cause frostbite. The time is selected after the end of frost, that is, around the middle of April in spring. At this time, the climate is more suitable and conducive to growth recovery
