A Detailed Explanation of the Latest Peanut Sprouting Methods and Key Technical Points
The peanut is a common cash crop with extremely high nutritional value. It is often used for nourishment and tonification, and it can also have the effect of prolonging life. When planting, in order to ensure its germination rate and avoid excessive waste of seeds, it is subjected to sprouting treatment before planting. After sprouting, peanut seeds can not only achieve a germination rate as high as 95% or more, but also emerge uniformly, which is convenient for management. Below, the editor will bring you its sprouting methods. Let us learn about them together.
1. Sunning the seeds
After long-term storage, peanuts will absorb moisture from the air, making the seeds' moisture content relatively high and unsuitable for sowing. Therefore, before sowing, the peanuts should first be sunned for one or two days. When sunning the seeds, choose clear weather. Do not place the peanuts directly on cement ground or stone slabs when sunning. Use cloth or bamboo utensils as a base to prevent high temperatures from scorching and damaging the seeds and affecting the germination rate.
2. Shelling and selecting grains
After sunning the seeds, they can be shelled. Note that the closer the shelling time is to the sowing time, the better. It is best to shell and sow as you go. When shelling, it is best to do it manually, as machinery easily damages the seeds. After shelling, use screens for grading and grain selection. Generally, 5 mm and 7 mm screens are used. First use the 7 mm screen for screening, select the seeds, and then use the 5 mm screen for screening. Finally, the small and light seeds left behind are not suitable for sowing. Generally, the first two types are used for sowing.
3. Soaking seeds to promote sprouting
After selecting seeds that are large and heavy, plump, disease-free, and undamaged, the step of soaking seeds to promote sprouting can be carried out. There are two methods for soaking seeds to promote sprouting. One is to soak the seeds in warm water at 30-40 degrees for 6-8 hours so that they absorb enough water, then remove them and let them dry slightly, and then place them in a greenhouse environment at 25-30 degrees. A wet towel can be used to cover them, and they should be rinsed once a day to maintain moisture, so as to avoid overheating and causing seed rot. The second is to place the seeds in layers with wet sand at a ratio of 1:5 so that they absorb water and germinate. Whichever method is used, temperature, moisture, and ventilation must be maintained. Once most of the seeds begin to sprout, they can be sown.
4. Coating and seed dressing
Before sowing, coat with Raxil suspension seed coating agent. The usual dosage is 0.3% of the seed amount. When sowing, use organic fertilizer and chemicals for seed dressing. Seed dressing with organic fertilizer can promote germination as quickly as possible, and seed dressing with chemicals can prevent and control most diseases. Generally, for each mu, 1 kilogram of phosphorus and potassium fertilizer is used for seed dressing, and there are many choices of chemicals, which can be combined on your own, but pay attention to the concentration to avoid causing chemical damage to the seeds and affecting germination.
