The seeds must be aired before entering the store

Before seeds are put into storage, drying in the sun for 3 to 5 days has many advantages.

First, reduce the moisture content The newly harvested seeds have a higher moisture content and are air-dried to reduce the moisture content, promote seed dormancy, weaken the respiration of the seeds, and prolong the life of the seeds.

Second, improve the germination rate Drying the seeds can increase the vitality of embryos and maintain the normal germination ability of the seeds. According to the experiment, the germination rate of the seeds of less sun-dried seeds of the same species of corn after drying in the autumn is 10-20% higher.

Third, to kill germs in the sun drying, ultraviolet radiation can kill some of the bacteria attached to the seed surface, to avoid the occurrence of insect gall, rotten, degenerative phenomenon.

Fourth, to promote the maturation of mature seeds in two stages, the first is the maturity of the seed morphology, called the species mature, and then it is the physiological maturity. When the seeds are harvested, they generally only mature in form. Such seeds have weak vitality, and the seedlings are not neat after planting. The physiologically mature seeds have strong vitality and high emergence rate.
