Introduction to the causes and Preventive measures of premature Senescence in Rice

In the new planting project, what is indispensable is rice. Rice is an indispensable crop, and its daily needs are so large that many people can grow it. However, various problems often arise in the whole process of rice planting, in which premature senescence is very common, and the key to this premature senescence occurs in the middle and later stage of rice heading. Once there is premature senescence, the production is bound to suffer harm, so how to prevent it? Let's master it together.

Key points of ways to prevent premature senescence in rice planting

1. Nutrients should be abundant and harmful substances in the soil should be eliminated.

The growth and development of rice must have sufficient nutrients. If the nutrients are insufficient, it is very easy to appear premature senescence. The key is due to the lack of certain elements in the soil, so it must be adequate in the case of fertilizer application, and it should be well manipulated in the value of fertilizer concentration. In addition, if there are a lot of harmful substances in soil, it will damage the roots of rice, and the more serious ones will continue to blacken or rot, so rice can not grow and develop normally, so premature senescence will emerge. therefore, in the case of growing rice, it is necessary to select the soil that is most suitable for it and remove all the harmful substances in it.

2. The planting time and relative density should be controlled well.

The occurrence of premature senility is immediately related to the whole planting process. if it is rainy and sunny, it is very easy for the soil to show lump, so that the root of rice can not be very permeable, and the charm will become weaker and weaker, thus harming the root and causing premature senescence. If planting in order to increase sales, and the relative density will be manipulated very large, rice can not all normal growth and development, their digestion and absorption of nutrients will not be abundant, very easy to have premature senility.

3. Temperature and sunlight during paddle period of rice

Effective and reasonable management methods should be used in the whole process of rice planting. If there is too much water in rice for a long time, or if the water is removed prematurely when it is obtained, it is very easy to lead to premature senescence. In addition, the temperature of rice paddling is also related to sunlight exposure. If the temperature is less than five or six degrees, it will lead to a change in the hue of rice, the key is that this kind of rice can not resist cool air, leading to premature senescence.

4. Prevention of premature senescence of rice * soil is very important

If you want to prevent the premature senescence of rice, you must choose the most suitable soil. If you encounter poor air permeability, you can improve the soil. In the case of ploughing, you should apply sufficient base fertilizer to ensure the organic matter of the soil. When planting, you should manipulate the relative density, and you do not have to make your own damage more serious because of the pursuit of perfect production.

That is to say, there is a detailed introduction to the premature senescence of rice, in order to prevent the premature senescence of rice, this kind of professional knowledge must be clear, in addition, in the case of planting, we must prevent and carefully manage the rice, every stage guarantee bit, in order to prevent the premature senescence of rice.
