Seed selection and sowing of peanuts before stripping the seed coat, from the net shape, the size of the pod, the color of the inner seed coat, the bending of the pod, the degree of the concave tip of the fruit, etc., the peanuts with the larger difference are removed. The remaining peanuts are selected at noon on sunny days, and are continuously irrigated on the mud for 3 to 4 days. Do not crush the peel when drying.
About 10 days before sowing, the shelling began. After shelling, it is necessary to carry out 2 selections. The selection criteria are: the color of the peanuts is pink, the inner seed coat is fine and smooth, and the seeds are oval. For these features, remove long, round and other colors of peanuts. When the machine is planted, the other peanut seeds in the seeding box should be removed, and the seeding wheel should be manually arranged to clean the other kinds of peanuts in the seeding tank and the lower seeding device to ensure the purity of the peanuts during sowing and reduce the physical mixing opportunity.
Field selection was carried out in the field during the late growth stage of peanuts, and the plants with different differences were removed from the breeding fields. When harvesting, you have to harvest and choose seeds. Seed selection should be carried out simultaneously with the control of the peanut plants and the control of the pods. Peanut plants that do not meet the characteristic characteristics are selected and stored together with the pods, and finally treated as miscellaneous fruits.
After harvesting and drying the field, the peanuts will be placed together on the peanut ridges every 2 rows, and in the ground for 4 to 5 days depending on the weather. During the noon, turn around 2 times. The removed pods are timely cleaned out of the mulch, leaves, fruit stalks, soil and other debris, and are evenly spread according to the size of the drying field. In the evening, pile up, spread out during the day, and after 4 days of continuous drying, stack them in piles for 2 days, during which time you can not use plastic sheets to make cloth. After 2 days, spread out and dry, when the water reaches about 9%, it can be stored.

Surfactant means a substance that can significantly reduce the surface tension of the target solution. It has a fixed hydrophilic and oil-wet group, which can be arranged directionally on the surface of the solution. The molecular structure of surfactant has two sexes: one end is hydrophilic group, the other end is hydrophobic group; Hydrophilic groups are often polar groups, such as carboxylic acid, sulfonic acid, sulfuric acid, amino or amine groups and their salts, hydroxyl, amide groups, ether bonds can also be polar hydrophilic groups; Hydrophobic groups are usually nonpolar hydrocarbon chains, such as more than 8 carbon atoms. Surfactants include ionic surfactants (including cationic surfactants and anionic surfactants), non-ionic surfactants, amphoteric surfactants, compound surfactants and other surfactants, etc
