1.选地:要选择土壤肥沃、有水利灌溉条件的田块作为种子繁殖田,但切忌重茬。这样既可提高种子的繁殖系数,又能减少因上年麦田残留麦粒在翌年出苗而造成混杂。 2.播种:①播种前的选种(筛选或机械选)、晒种(人工晾晒)、拌种(防病及防虫药剂拌种)等措施,要严格按不同品种分别进行处理,所用器械、包装袋等用具要清理干净,并有专人一直负责到底。②繁育品种的种子发芽率及净度要高,子粒要均匀整齐。③播种时,种子的运输及换品种的过程中,要避免人为的差错。为了便于记忆和区别相 1. Election: To choose the fertile soil, water irrigation conditions of the plots as a seed breeding field, but should not stubble. This will not only increase the seed multiplication coefficient but also reduce the confusion caused by the emergence of the remaining grain in the wheat fields in the following year. 2. Sowing: ① Before sowing (screening or mechanical selection), drying (artificial drying), seed dressing (anti-disease and pest control agent dressing) and other measures should be strictly according to different varieties were handled, the use of equipment, Bags and other appliances to clean up, and someone has been responsible for the end. ② Breeding varieties of seed germination rate and high purity, grain should be uniform and tidy. ③ sowing, the seeds of the transport and change of species in the process, to avoid human error.
