Reasons for slow growth of Rice after planting

The rise in temperature in spring is the beginning of farming. Many farmers react to the slow growth after planting rice. What's going on? What are the reasons for the slow growth of rice after planting? Let's take a look at the detailed introduction.

1. Drug damage

First of all, there is the drug damage caused by excessive use of pesticides, which may lead to slow growth of seedlings, because the scope of use of pesticides is limited, improper use or high concentration will cause harm. For example, if the herbicide is sprayed on the seedlings, the resistance of the seedlings is weak, which may inhibit its growth and cause it to grow slowly. In addition, the combined use of a variety of drugs, their mixture or the main cause of phytotoxicity.

2. The temperature is too low

The root growth and development of rice mainly depends on its leaf photosynthesis. if the temperature is too low during seedling growth, its photosynthesis will be weakened or stopped, resulting in insufficient synthetic nutrients and insufficient root growth. Therefore, the root growth will be very slow, resulting in slow seedling growth.

3. Insufficient water level

Rice needs water in addition to temperature during its growth and development. Under the condition of sufficient water, the roots of seedlings take root more than those without water, so shallow water irrigation is a necessary condition for the growth of leaves and roots.

4. the quality of seedlings is poor.

When raising seedlings, the root growth of seedlings is poor due to too much watering or high temperature in the seedling bed, and the phenomenon of slow growth will appear after transplanting.

5. The base fertilizer is not mature.

When farm manure is applied before planting, it is not completely mature. If the irrigation is too deep, reductive organic acids will be formed under sunlight, which will poison the rice roots, thus affecting the growth of seedlings and making them grow slowly.

The above is the introduction of the reasons for the slow growth of rice after planting. I hope it can help you. If you want to know more about it, please follow us.
