What are the latest factors affecting peanut seed germination

Peanut is very popular in China, not only has a high edible value, but also a major oil crop in China. Therefore, there are a lot of people growing peanuts now. When planting peanuts, many people are very concerned about the germination rate of peanut seeds. The germination rate of peanut seeds will be affected by many factors. So what are the specific factors? The following editor will give you a brief introduction, let's have a look!

1. Seeds

The quality of peanut seed itself is the primary factor affecting its germination rate. When we collect peanut seeds for drying treatment, if peanut seeds are injured or improperly kept, it will affect the vitality of peanut seeds, resulting in the decline of peanut seed vigor or even loss of vitality, thus unable to germinate and emerge. Then there is peanut seeds that cannot germinate if they are dormant. Therefore, when we sow seeds, we should pay attention to whether peanuts are dormant or not, and we should break the dormant period of seeds before sowing.

2. Temperature

Temperature control is very important after peanut seeds are sown. If the temperature is not suitable, it will have a great impact on the germination of peanut seeds. If it is light, it will reduce the germination rate, and if it is heavy, it will cause the seed to lose its vitality and cannot germinate at all. After sowing, the lowest temperature should not be lower than 12. The higher the temperature is, the faster the seed will germinate. Generally, about 30 degrees is the best germination temperature for peanut seeds. But the temperature should not be too high, if it exceeds 40 degrees, it will also inhibit seed germination.

3. Moisture

When sowing peanut seeds, it is necessary to have sufficient water content to ensure that the seeds can germinate normally. Under normal circumstances, peanut seeds must absorb at least ordinary water of their own weight before they can germinate normally. And when sowing, the soil should also have sufficient water content, which should be kept at about 55%. After peanut seeds absorb enough water, the respiration and enzyme activity of peanut seeds will also be enhanced. The nutrient elements in cotyledons will also be gradually transformed into amino acids and other nutrient elements to provide sufficient nutrition for seed germination and seedling emergence.

4. Oxygen

Oxygen is also a major factor affecting peanut seed germination. Because peanut seeds are originally oily, they do not have enough oxygen atoms. But if you want it to germinate normally after sowing, you need a lot of oxygen. Therefore, when we sow, the soil should be loose enough, suitable for moisture and highly permeable. The sowing depth should be controlled, and the sowing should not be too deep, so as to prevent the respiration of the seeds from being affected and ensure normal germination and emergence.

The above is a brief introduction to the factors affecting peanut seed germination. That's all for today's introduction. This article is for reference only. I hope it can help you all.
