What are the reasons for slow growth after planting rice?

As temperatures rise in spring, farming and planting begin. Many farmers report that rice grows slowly after planting. What is going on? What are the reasons for slow growth after planting rice? Let's take a look at the detailed explanation.

1. Phytotoxicity

The first is phytotoxicity caused by excessive use of pesticides. Phytotoxicity may cause seedlings to grow slowly, because the range of pesticide use is limited, and improper use or too high a concentration will cause damage. For example, if herbicide is sprayed on seedlings, the seedlings have weak resistance, which may inhibit their growth and cause them to grow slowly. In addition, the combined use of multiple chemicals is a main reason for mixing them or producing plant toxicity.

2. Too low temperature

The growth and development of the rice root system mainly depends on its leaf photosynthesis. If the temperature is too low during seedling growth, its photosynthesis will weaken or stop, resulting in insufficient synthesized nutrients. The root system does not have sufficient nutrition for growth, so root growth will be extremely slow, causing the seedlings to grow slowly.

3. Insufficient water level

In addition to temperature conditions, rice also needs water during growth and development. In an environment with sufficient water, seedling roots take root faster than in an environment without water, so shallow water irrigation during planting is a necessary condition for leaf and root growth.

4. Poor seedling quality

During seedling raising, because the seedbed is watered too much or the temperature is too high, the seedling root system grows poorly, and slow growth will appear after transplanting.

5. Base fertilizer not decomposed

When farmyard manure is applied before planting and is not fully decomposed, if irrigation is too deep, reducing organic acids will form under sunlight, which will poison the rice root system, thereby affecting seedling growth and making it grow slowly.
