To ensure that peanuts have high germination rate, strong seedlings, high yield, and good quality, it is very important to seize the four stages of proper harvesting, selective seeding, drying, and safe storage. The peanuts harvested at the appropriate time for harvesting are harvested earlier than the peanuts used for oil extraction. Peanuts harvested on a regular basis show white inner husks and strong seed vigor; the tops of the husks have stopped growing, the upper leaves are yellow, the lower middle leaves are detached, and the stems are also yellow and have irregular dark spots. Most of the shaved pods are clearly reticulated, and their kernels are full. Generally, early-maturing varieties and infertile parcels are received first, and late-maturing varieties and sufficient land for water and fertilizer are received late. Harvested soils had higher germination rates than soils harvested when dry. When picking and picking the fruit, it is necessary to remove the miscellaneous matters, and to remove the pods of the dead plants, the pods that have germinated, the pods that fall apart, and the tender fruits. These fruits are mostly pods and dead embryos. They cannot germinate easily Mild rotten, can not be used for planting. The moisture content of freshly harvested peanuts is generally between 45% and 50%, and the water content is too high. In order to ensure the quality and safe storage of peanut seeds, they should be brought upside down and put in the field for drying, and they should be transported to the drying field two days later for picking the seeds. During the drying process, it is necessary to prevent rain and heat. The fevered seeds cannot germinate. If it is raining during the drying season, it must not be piled into piles or packed in baskets. This will make the seeds hot. The correct approach is to spread the peanuts thinly on the floor to allow the water to slowly dissipate. Drying should be diligent when turning, when shaking the pods with a sound, bite pods when the crisp, and then turn the sun one day, peeling open the shell, bite the teeth with a crisp, easy to take off the seed coat skin, Can be put into storage, this time the water content of kernels is generally about 10%. Peanuts used for storage and storage, and a clean tank is ideal. Put the cylinder on the ground before loading and put the brick under the jar. First spread a layer of hay ash in the cylinder, then pour the freshly-dried pods. After 6 hours, sprinkle a layer of about 10 cm thick hay ash on the peanuts, and then seal the cylinder head.
