How to sow rice

Soil preparation: Before planting rice, the soil in the paddy field must be ploughed to make it soft. This process is divided into three stages: rough tillage, fine tillage and leveling. In the past, animals and plows, mainly buffaloes, were used for soil preparation and ploughing, but now machines are used for soil preparation.

Seedling raising: farmers first cultivate seedlings in a field, which is usually called a seedling field. After sowing rice seeds, most farmers will sprinkle a layer of rice husk ash on the soil; In modern times, special seedling-raising centers use seedling-raising boxes to make rice seedlings grow. Good rice seedlings are the key to the success of rice cultivation. When the seedlings grow to about eight centimeters, they can be transplanted.

Transplanting: carefully insert the seedlings into the rice field, and the space is neat and orderly. The traditional transplanting method will mark the rice field with seedling rope, seedling label or transplanting wheel. When transplanting rice by hand, you will wear a seedling separator on your left thumb to help farmers divide seedlings and insert soil. The climate of transplanting rice seedlings is very important, such as heavy rain will damage the seedlings. There are many rice transplanters used in modern times, but in paddy fields with large fluctuations and non-square shapes, manual rice transplanting is still needed. Generally, seedlings will show a north-south trend. It is also more convenient to throw seedlings.

Weeding and pest control: When the seedlings grow, they should always be cared for and uprooted, and sometimes pesticides should be used to remove pests (such as snails).

Fertilization: the tillering stage is called when the seedlings are raised and the first rice stalk grows. During this period, fertilization is often needed to make rice seedlings grow strong and promote the fullness and quantity of rice quality in the future.

Irrigation and drainage: Rice is more dependent on this procedure. Take upland rice as an example, it is upland field, and the process of irrigation and drainage is different. However, it is generally necessary to strengthen irrigation after transplanting, when young panicles are formed, and at the heading and flowering stage.

Harvest: When the ears of rice droop and are golden and full, you can start harvesting. In the past, farmers cut them off one by one with sickles and tied them up, and then separated them with threshers. There are harvesters in modern times, which directly separate the rice ears from the stems after they are involved, and the rice ears become rice one by one.

Drying and sorting: The harvested rice needs to be dried. In the past, it was mostly dried in the front yard of Sanhe Hospital, and it was necessary to turn it over from time to time to dry the rice. Screening is to remove impurities such as shriveled grains, separate the grains by electric thresher, windmill or manual shaking, and automatically screen out full and thick rice by wind power.
