Analysis of the Latest Reasons for Slow Growth After Rice Planting
The rise in spring temperatures marks the beginning of farming and planting. Many farmers have reported slow growth after planting rice. What is going on? What are the reasons for slow growth after rice planting? Let's take a look at the detailed introduction.
1. Phytotoxicity
First is the phytotoxicity caused by excessive pesticide use. Phytotoxicity may cause slow growth of seedlings, because the scope of pesticide use is limited, and improper use or too high a concentration will cause damage. For example, spraying herbicide on seedlings, which have weak resistance, may inhibit their growth and cause them to grow slowly. In addition, the combined use of multiple chemicals is a main reason for their mixing or causing plant toxicity.
2. Too Low Temperature
The growth and development of the rice root system mainly depends on the photosynthesis of its leaves. If the temperature is too low during seedling growth, its photosynthesis will weaken or stop, resulting in insufficient synthesized nutrients. The roots do not have sufficient nutrients 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 at planting time is a necessary condition for leaf and root growth.
4. Poor Seedling Quality
During seedling raising, excessive watering of the seedbed or too high a temperature leads to poor root growth of the seedlings, and after transplanting, slow growth will occur.
5. Unrotted Base Fertilizer
When farmyard manure applied before planting is not completely rotted, if the irrigation water is too deep, reducing organic acids will form under sunlight, poisoning the rice roots and thereby affecting seedling growth, causing it to grow slowly.
