How to prevent and control the late ripening of rice

Rice is the most common staple food in China. After shelling rice is rice. It is best for a person to eat 700 grams of rice every day. Because rice is rich in protein, it can ensure the development and health of the body. Last time, I talked about the reason why rice is green and late ripening. Today, the editor will tell you how to prevent rice from green and late ripening.

1. Pay attention to planting density

The planting density of rice has a great influence on the growth and development of rice, and the planting density should not be too thin and too dense. If the planting density of rice is not controlled reasonably, it will not only lead to greedy green and late ripening, but also increase the probability of occurrence of diseases and insect pests, which is not only useless but also harmful to rice. The specific planting density depends on the variety of rice and the fertility of the soil. For example, hybrid rice can plant about 20,000 holes per mu of fertile soil and 1-2 thousand holes per mu of fertile soil.

2. Rational fertilization

Reasonable fertilization should be carried out according to the growth of rice, and the right medicine should be given to the case, and what kind of fertilizer should be applied under what conditions. Can not be determined according to their own mood, must not be too much nitrogen fertilizer, or only nitrogen fertilizer. Nitrogen fertilizer can indeed promote the symptom development of crops, but too much application will make rice unable to absorb and transform completely in a short time, and the residue in rice will make rice green and mature late. It is necessary to properly apply some phosphorus and potassium fertilizer to supplement more trace elements for rice.

3. Temperature and humidity control

Rice is a kind of crop that likes water and temperature. the temperature and humidity in the rice field must be controlled well. the optimum temperature for rice growth is about 30 degrees, and the water should be flooded up to people's ankles. If the wet temperature of rice is not met, it will seriously affect the normal growth of rice, resulting in the phenomenon of greedy green and late ripening.

4. Disease control

Rice will also encounter a lot of diseases and insect pests, such as rice blast, rice planthopper and so on. These diseases will seriously harm the normal growth of rice. Diseases and insect pests will destroy the nutrient transport ducts of rice, resulting in rice not having enough nutrients to mature in a normal period of time, resulting in greedy green late maturity. Therefore, we must prevent the disease in advance. If any disease occurs, we must find out what kind of disease it is, prescribe the right medicine and deal with it.

The above are the prevention and control methods of green and late ripening rice sorted out by the editor, and some of them are not listed one by one, such as ensuring the light time and so on. Late ripening of rice is the most common symptom of rice, and it is also the easiest to prevent and cure. As long as the various planting conditions of rice are ensured, the late ripening of green rice will be rare.
