How To Ensure That The Oil Extraction Rate Of Peanuts Is High
it is very important to ensure that the peanut has high oil extraction rate, high yield and good quality, and it is very important to grasp the four stages of suitable harvest, selective seeding, sun-breeding and safe storage.
Appropriate harvest
The peanuts used for seeding are harvested earlier than the peanuts used for oil extraction. Peanuts harvested in a timely manner, the inner membrane of the shell is white, the seed viability is strong; the top of the plant has stopped growing, the upper leaves are yellow, the middle and lower leaves are off, the stems are yellow, and irregular long black spots appear. Most of the cut pods are obvious and the seeds are full. Generally, early-maturing varieties and infertile plots are harvested first, and late-maturing varieties and water-fertilizer plots are late. When the soil is wet, the harvested pods have a higher germination rate than when harvested.
2.Carefully selected seeds
When picking fruits, remove impurities, remove pods of dead plants, sprouted pods, pea pods and tender fruits. These fruits are mainly capsules and dead embryos. They neither germinate nor mold. Easy to use.
3.Sun seed
The moisture content of the newly harvested peanuts is generally 45 to 50 percent, and the moisture is too high. In order to ensure the quality and safe storage of peanut seeds, they should be placed in the field and dried in the field after harvesting. After two days, they should be transported to the drying field to pick the pods. It is necessary to prevent rain and heat during the drying process. The hot seeds can't germinate. If it is raining during the seeding, do not pile the pods into large piles or put them into the basket, which will cause the seeds to heat up. The correct way is to spread the peanuts thinly on the inside of the house to let the water slowly disappear. When you are doing sowing, you should diligently turn over the field. When there is a sound in the shaking pod, when the biting pod is crispy, turn it over for a day, peel off the shell, and bite the nut with the teeth. When the peel can be easily smashed by the hand , you can enter the warehouse, at this time the water content of the seed is generally around 10%
4.Storage
The storage uses peanuts and uses a clean tank. Place the cylinder on the ground and place the brick under the cylinder before planting. First sprinkle a layer of hay ash in the tank, then pour the freshly dried pods. After 6 hours, sprinkle a layer of about 10 cm of hay ash on the peanuts, then seal the cylinder head.
