Rice Planting Technology
Rice Planting Technology
rice, including paddy fields and transplanting, was invented in China. Legend has it that Shennong taught people how to grow rice. We have grown 500 hectares, 1000 hectares, 5000 hectares of rice in Central Asia, South Asia and Africa.
the cultivation of rice in addition to the traditional artificial farming methods, there are also highly mechanized farming methods. But still do not miss the following steps:
1. Soil preparation: Before planting rice, the soil in the rice field must be turned over to make it soft. This process is divided into three periods: coarse tillage, fine tillage and leveling. In the past, animal power and ploughs, mainly buffalo, were used to prepare the fields, but nowadays machines are used to prepare the fields.
2. Seedling raising: Farmers first raise seedlings in a certain field. This field is often called a seedling field. After sowing rice seeds, farmers will mostly sprinkle a layer of rice husk ash on the soil. In modern times, special seedling raising centers often use seedling raising boxes to grow rice seedlings. Good rice seedlings are the key to successful rice cultivation. When the seedlings grow about eight centimeters high, they can be transplanted.
3. Transplanting: Carefully insert the seedlings into the rice field with an orderly space. The traditional planting method uses a rope, a seedling marker, or a transplanting wheel to mark the rice field. When transplanting rice seedlings manually, a seedling divider will be worn on the thumb of the left hand to help farmers separate the seedlings and insert them into the soil. The climate of transplanting is very important, such as heavy rain will damage the seedlings. There are many transplanters for transplanting rice seedlings in modern times, but manual transplanting is still needed in paddy fields where the land fluctuates greatly and the shape is not square. The seedlings generally run north-south. There is also a more convenient way to throw seedlings.
4. Weeding and deinsecting: When seedlings grow, they must always take care of them, pull out weeds, and sometimes use pesticides to get rid of pests (such as Pomou snails).
5. Fertilization: Seedlings are called tillering stage when they are high and grow the first rice stem. Fertilization is often needed during this period to make the rice seedlings grow robustly and promote the fullness and quantity of the finished rice in the future.
6. Irrigation and drainage: Rice is more dependent on this procedure. For upland rice, the process of irrigation and drainage is different. However, it is generally necessary to strengthen water irrigation at the heading and flowering stage after transplanting seedlings, when young panicles are formed.
7. Harvest: When the ears of rice hang down and are golden and full, the harvest can begin. In the past, farmers cut the ears one by one with a sickle, then tied them up, and used a threshing machine to separate the ears of rice. In modern times, there are harvesters. After the ears of rice are involved, the ears of rice are directly separated from the stems of rice, and the ears of rice become rice one by one.
8. Drying and screening: The harvested rice needs to be dried. In the past, it was mostly dried in the front yard of the Sanheyuan. It needs to be turned over from time to time to dry the rice. Screening is to delete impurities such as shrunken valley, use electric grain dividing machine, windmill or manual shaking to divide the valley, and use wind to lift the valley.
