Reasons for Rice Greedy and Late Maturity

Rice is the staple food of nearly half the people in the world, but did you know that sweet and delicious rice will encounter a lot of problems in the process of planting? Greedy green late ripening is one of them, greedy green late ripening is in the vernacular stage of rice ripening, but the leaves are still green. So what on earth is the reason for the late ripening of rice? let's take a look.

1. Nitrogen fertilizer

Nitrogen fertilizer is a very good chemical fertilizer for promoting crop growth and increasing crop yield in the process of crop growth. But many friends are afraid that the yield of rice is not high, in order to improve the yield of rice, continue to be nitrogen fertilizer, resulting in excessive application of nitrogen fertilizer. Because many people think that the more nitrogen fertilizer is used, the better the rice yield will be. In fact, this will be counterproductive, because excessive nitrogen fertilizer will affect the growth and development of rice, rice can not absorb nutrients normally, resulting in nutritional imbalance in rice. In the later stage, the normal mature stage of rice is still constantly absorbing nutrients, resulting in the phenomenon of greedy green and late ripening, which not only can not increase the yield, but also reduce.

2. Lighting

Rice is a light-loving crop that shines for at least eight hours a day. Because the organic nutrition of rice comes from its own photosynthesis, and light is a necessary condition for photosynthesis. If there is not enough light time, the photosynthesis of rice will decrease, and the nutrients and waste materials in the body can not be discharged in time. Rice retains too much nutrients, which will be absorbed and transformed all the time, resulting in greedy green and late ripening. And if the rice is too dense, the rice leaves are too dense, the lower rice leaves squeeze each other, can not accept the light, lack of light, resulting in greedy green late ripening.

3. Moisture

As we all know, rice, as its name implies, has a high demand for water. After transplanting seedlings, the moisture in the rice field must be ensured, and the moisture must at least reach the human ankle. It is necessary to keep the rice fields moist and watery at any time, so as to ensure the normal growth of rice. If there is a lack of water, the seedlings will not be able to absorb nutrients normally. As a result, rice ripens later and leaves yellowing too late. But the water should not be too much, too much will rett the rice.

4. Temperature

Rice is also very strict on temperature requirements, in the seedling growth, can adapt to the lowest temperature of 10 degrees, the best development temperature of 30 degrees. If the temperature is lower than 12 degrees and higher than 40 degrees, the growth and development of seedlings will stop, and less than 15 degrees will not be conducive to the absorption of nutrients in rice, which will lead to the lack of nutrients in rice, unable to grow and develop normally, and the phenomenon of greedy green and late ripening.

These are the reasons for the late ripening of rice. Rice is a kind of crop that likes light, temperature and water, all of which are indispensable to rice. In fact, nitrogen fertilizer is of great help to crops, but excessive application will still have a great impact on more crops.
