According to the practice over the years, following the following steps in the process of seed harvesting and processing can ensure that the quality meets the national standard, that is, the cleanliness is 99%, the moisture content is less than 8%, and the seed has no adhesion phenomenon. 1. Seed-collecting: about 40 days after artificial pollination, the melon peel can be harvested. Parents can use this method to harvest seeds. The seeds are cut in kind, and the seeds are picked up. The amount of seeds is kept in the woven bag for a long time. On the bag mouth; when the amount is small, put in the non-ferrous capacity (avoid using iron); crush the fruit and leave the appropriate amount of liquid to prepare for fermentation. 2, fermentation: fermentation at room temperature for about 24 hours, can not be rain shower, avoid pouring into the water, during which can be regularly stirred, rainy weather can be determined according to the weather whether the panning. 3. Washing: After the seeds are fermented, the panning is the key. The seeds are poured into porcelain basins or plastic buckets. Soon, the seeds are divided into three layers: the seeds, leaves and other impurities float on the upper layer and can be removed; the middle layer is removed. A mixture of seeds and impurities; full seeds sink to the bottom,. After the upper layer is poured out, the pan is not washed until the seeds have no sticky mass and no other impurities. 4. Drying: The seeds after washing are promptly dried. The drying place requires smoothness and cleanliness. The seeds are diluted and periodically turned over until they are dry. The dried seeds touched hands and broke the seeds without skin. 5. Primary election: Dried seeds should be processed in time. First, continue to peck the seeds by hand until the seeds are separated. Next, sieve with a sieve and remove impurities with a pestle. 6. Selecting and coating: after the seeds are selected, select the seeds and then select the full seeds, coat them with the seed coating agent, and dry them until the moisture content is less than 8%.
