Wheat self-cultivation skills
If you are preparing to use your own wheat as the next year's seed, you should do some preparatory work during the wheat harvest period. From harvesting to storage, you should take it seriously, mainly to do the following:
Ensure wheat purity: decontamination should be carried out in the early stage of wheat harvest. When harvested, the wheat is harvested, single-sun, and stored separately. When drying, you should take a single shot and do not use it with other varieties and ordinary wheat to prevent mixing. The name of the variety should be marked when stored to prevent confusion with other varieties and ordinary wheat, and not to be in the same place as ordinary wheat.
Scientific drying: Repeated drying before storage, so that the water content of wheat seeds can be safely stored, and the safe storage moisture of wheat is less than 13%. However, the stored wheat seeds should not be overexposed. It is forbidden to sown on the cement floor. Because the temperature of the cement floor is too high, it is easy to burn the seeds.
Suitable storage container and environment: It is best to use cement cylinder and porcelain cylinder for storage. It can't be stored in plastic bag. The plastic bag is not breathable, hindering the seed to breathe, it will reduce the germination rate, and the excess water can not be dispersed, which is easy to cause mildew. . The wheat seeds should be stored in a dry and ventilated place, and the bottom of the container of the wheat seeds should be covered with moisture-proof materials such as wood boards and stones. During the storage process, it should be aired frequently and ventilated at the right time. Can not be stored in the kitchen, so as to avoid pyrotechnics, resulting in seed color, moisture reduction, and even fever, affecting the seed germination rate; do not mix with ammonia, urea and other ammonia nitrogen fertilizer in a room, due to high temperature during this period, humidity Large, these ammonia nitrogen fertilizers are extremely volatile, and the volatile ammonia gas will corrode seed cells and seed embryos, seriously affecting germination rate and seed vigor.
Insect-proof and rodent-proof: The wheat seeds are stored in hot air after drying, which can reduce insect pests. The cement cylinder and the porcelain cylinder are used for storage, which can play the role of preventing rodents and pests. At the same time, it can be used to prevent insects and rats, and its special medicine is civilian aluminum phosphide. It can control corn insects, saw grain thieves and other food pests. One tablet per 200 kilograms of wheat seeds, wrapped in cloth and put into the seeds about 33 cm, sealed 7 Kill pests in days. (Jia Youjiang)
