Once there is premature aging, the yield is bound to be affected. How to prevent it? Let's take a look at it. Main points of methods for preventing premature aging in rice planting 1. Nutrients should be sufficient and the soil harmful substances should be removed. When rice grows, it needs enough nutrients. If the nutrients are not enough, it is prone to premature aging. This is mainly due to the lack of certain elements in the soil, so it must be sufficient when fertilizing, and the fertilizer concentration should be controlled. In addition, if there are a lot of harmful substances in the soil, the roots of the rice will be damaged, and the black will be black or rot, so the rice will not grow normally, so the premature aging will occur, so choose when planting rice. It is most suitable for its soil and removes all harmful substances inside. 2, planting time and density should be well controlled The occurrence of premature aging is directly related to the planting process. If it is rainy, the soil is prone to induration, so that the roots of the rice can not be well ventilated, the vitality will become weak, and the roots will be affected. Damage, causing premature aging. If the density is controlled to be particularly large in order to increase sales during planting, rice can not grow normally, and they will not absorb enough nutrients, and it is easy to have premature aging. 3. Rice filling temperature and illumination It is necessary to manage it rationally and effectively during the rice planting process. If the rice contains too much water for a long time, or if the water is removed too early at the time of harvesting, it is easy to cause premature aging. In addition, the temperature and light during paddying are also very high. Relationship. If the temperature is lower than five or six degrees, the color of rice will change, mainly because these rice varieties can not resist cold, and thus premature aging. 4, rice premature aging prevention and control of soil is critical If you want to prevent premature aging of rice, you must choose the soil that is most suitable for it. If you encounter poor permeability, you can improve the soil. When you are preparing the soil, apply enough base fertilizer to ensure the soil fertility. Density, don't let yourself lose more because of excessive pursuit of production. The above is the introduction of premature aging of rice. In order to avoid premature aging of rice, these relevant knowledge must be clear.
