Potato multiple cropping rice is a new cultivation technique promoted in recent years. It is of great significance to improve the land utilization rate of the first season rice cropland in the north, increase the multiple cropping index, change the cropping crop into two cropping crops, and cultivate in early spring to prevent the potato from degenerating and summer sowing , Increase production have very important practical significance. The yield per mu of potatoes can reach 1,000 to 1,500 kilograms and that of rice can be 350 to 400 kilograms per mu, which is a good way for farmers to produce high-yield and high efficiency. Here are some main cultivation techniques.
