With the continuous increase in the number of wheat production, large-scale farm production is no longer able to meet market demand. Many seed production enterprises have established seed production bases in the countryside. Although they are a small-scale production in one household, they can ensure that the whole village is well-connected, unified in variety, unified in planting, unified in command and management, and unified in harvesting. Seed purity can still be achieved. Guaranteed. Mainly to grasp the following key links, such as seed selection, seeding, management, harvesting, drying, storage and so on.
Selecting the best breeding material is the key. The propagation materials provided by seed companies must be high-purity seeds produced through Sanpu Tian.
Before sowing, sowing must be done. Before sowing, all other wheat varieties remaining at the bottom of the loquat must be completely cleaned, leaving no seeds. Method: The shaft can be removed and reinstalled. During the Qing dynasty, it must be noted that they cannot be carried out in the ground so as to prevent the seeds from scattering in the fields and causing mixed varieties.
The management must use the same variety no matter whether it is seed not enough or replanting seedlings after emergence, and it cannot be replaced by other varieties, so as not to cause mixed varieties. In the period of wheat turning green, jointing, heading, grouting and other periods, field inspections of the seed fields should be conducted, and the miscellaneous plants, inferior plants, and weeds should be removed and taken out of the field. For malignant weeds, wild oats and Aegilops tauschii, the whole plants are removed by stages before the flowering stage of wheat, and taken out of the field. Weeds should not be removed after the weed seeds have matured to prevent weed seeds from falling out of the field. During the grain-filling period of wheat, the seed field should be thoroughly inspected and the last cleaning operation of the hybrid plants and weeds should be carried out. Seeds for serious mixed wheat fields must be scrapped.
When harvesting, it is necessary to unify the harvesting equipment; before the operation, the harvester is cleaned, and the main part is the granary, header, and grain conveying pipe, and especially the granary must be cleaned. After the cleaning is completed, the harvester shall be allowed to run for 1 minute without any load, and the operation shall be started again so as not to cause confusion.
When drying and drying, it should be adjacent to the farmers who are drying the same wheat varieties. Before the sun to clean the sun, so as not to cause confusion.
After the storage is dried, the other materials in the woven bag should be dumped. If other wheat varieties have been loaded, it is best to turn the woven bag inside out and put it in seed. When transporting and storing at home, be sure to mark it and avoid storing it with other wheat varieties in a room or mixed.
