1, seed quality problems
In the selection of peanut seeds, the quality is not very high. For example, some friends use self-preserved species at home, some moldy, rotten, dried, etc., are directly taken to sow, and some seeds are directly rotted after sowing seeds. In the soil, it leads to emergence of seedlings. The solution: to buy good breeds, even if it is reserved, but also carefully selected.
2, drying problems
Peanut before sowing, the appropriate drying is OK, but to prohibit the sun exposure, because it may be peanut peeling sun burst crisp, that is, we say the sunburn seeds, leading to bad seedlings do not emerge. Solution: You can choose to dry, you can choose sunny weather, you can continuously dry for two hours a day or so, and not exposure to direct sunlight.
3, seed coating agent
According to theory, after peanut seed dressing, it can play a certain role in preventing bad seeds, but excessive use will inhibit the emergence of peanuts and cause seedling deficiency. Last year, a friend of spring peanut growing area said that his family’s One hundred acres of peanuts, because of the misuse of seed dressings, the dose was originally 15 kilograms of seed dose, the result was seen as 15 pounds, the dose increased by half, resulting in a lot of no emergence. Solution: When using peanut seed dressing, the dose must be asked. You can ask the salesperson, or call the manufacturer's telephone on the packaging, in accordance with the above instructions.
4, sowing temperature
The choice of temperature during sowing is particularly important. It mainly refers to the spring peanut area, because low temperature will affect the emergence of seedlings. Under normal circumstances, peanuts are planted at about 5cm, and when the ground temperature is above 15 degrees (some varieties require higher) The emergence of seedlings is very good. If the temperature is too low to reach the germination temperature of peanuts, it will cause seedling deficiency. Solution: Pay attention to the change of temperature during sowing, cool down or temperature too low, so you can sow for several days.
5, sowing depth
If the peanuts are sown too deeply, the time for peanuts to grow in the soil will be relatively prolonged. In the past, because the seeds were so deep that the peanuts did not sprout, there were many cases. Check out the causes and find out that many peanuts were rotted in the soil. In particular, seed dressing seeds, we must pay attention to the depth of sowing. Solution: The general sowing depth is recommended between 3-5cm. Whether it is manual or machine sowing, pay attention.
