麦种纯度高低,标志着一个单位的生产水平,同时也是衡量种子良纯化的实施程度。有了优良的品种,还应具备纯度较高的种子,才能促进麦子增产。三年来,我市先后在市良种场及34个乡(镇)建成了一批种子仓库,水泥晒场,种子检验室。每个乡(镇)还配备一台稻麦种子精选机和必备的种子检测仪器,以及各类种子器具。在种子硬件建设较完备的基础上,每年均按更新计划,逐步实施市乡联合统一供种。由此全市的麦种纯度明显改观,丰产方、线纯度达到一级良种水平,大田平均纯度也接近99％。现将我市麦种纯度的现状、问题、对策概述如下: The purity of wheat varieties, marking a unit of production level, but also measure the implementation of good seed purification. With excellent varieties, should also have higher purity seeds, in order to promote wheat yield. In the past three years, the city has built a batch of seed warehouse, cement drying yard and seed testing room in the city’s thoroughbred farms and 34 townships (towns). Each township (town) is also equipped with a rice seed sorting machine and the necessary seed testing equipment, as well as various kinds of seeds and equipment. On the basis of a more complete seed hardware construction, we will gradually implement the unified unified supply of urban and rural areas according to the updated plan each year. As a result, the purity of the wheat varieties in the whole city has obviously improved. The purity of the high-yielding sides and lines has reached the level of first-grade varieties, and the average purity of the field is also close to 99%. Now the status of the city of wheat purity, problems, solutions outlined below:
