Peanuts are one of the main sources of income for many farmers' friends. At present, peanuts from various provinces enter the harvest season. Rainy weather has negative effects on the harvesting and drying of autumn peanuts, and is likely to cause deterioration of the grains.
When the mangosteen is firm, the grain is full, and the seed coat becomes pink when it is ripe, it should be timely harvested. If it is harvested too late, the needle will be broken and germinated. After harvest, the mangosteen will be dried in time to moisture content below 10%. Store in a dry, ventilated place with special attention to rodents.
Peanut proper harvesting and safe storage are important measures to ensure the yield and quality of peanuts. The harvest is too early, which affects the accumulation of nutrients in the kernels, makes the seed kernels insufficiently filled, the pods are not full, there are many pods, the rate of kernels is low, and the oil content is decreased Harvested too late, fruit stems dry rotten, full fruit easy to fall off, easy to lose grain, rot grains increase, lose 10 million. The later the harvest, the lower the temperature, the fruit is not easy to dry, affect the product sanctions, or even lose their ability to live, reduce the germination rate. Especially early-maturing varieties, due to short body-sleeping periods, when the soil moisture and temperature are appropriate, can also cause a large number of germination losses, especially for peanuts for planting, should be harvested in time.
The newly harvested peanuts generally have a moisture content of 45% to 50%, a general moisture content of 45% to 50%, and a higher moisture content of the loquat fruit, up to 60%. If not dried in time, it is prone to mildew, deterioration, or frost damage. . In order to store safely and ensure the quality of peanuts, after harvesting, peanut plants bearing pods should be planted in the field for drying for 2-3 days to promote post-harvest and air-drying; When the pods are sunned and their mouths are brittle, their hands are squeaky, and the husks of the husks are easy to fall off, the water content is generally below 10%, and they can be stored in storage.
Since peanut seeds contain a large amount of hydrophilic substances such as proteins and carbohydrates, it is easy to absorb moisture in the air during the storage process, so that the respiration is enhanced, nutrients are consumed, a large amount of heat is released, the temperature of the seed pile is increased, and the seed is heated and moldy Deterioration, loss of growth ability. Practice has proved that when the temperature of the peanut storage place is about 9°C and the seed moisture content is 11%, the bottom of the stack will be hot and the oil yield will be reduced; when the seed moisture content is 13% and the temperature exceeds 17°C, the mold will start to form. If it exceeds 20°C, it will deteriorate. Even if the seed moisture content is below the safe storage moisture limit, it will be frozen at -25% cold. If the safe moisture limit is exceeded, the seeds can be frozen and degenerated at -3°C. Therefore, peanuts must be dried and ventilated during storage. If the moisture content of the seeds exceeds the safety limit or the temperature of the seed piles rises, they should be promptly turned upside down to ensure safe storage of peanut seeds.
