开展种子机械加工是种子公司求得质量第一,增加经济效益的重要措施,是提高种子质量,减少用种量,节约成本,实现种子质量标准化、供种商品化、服务社会化的重要手段。种子加工目的有三个方面:一是提高种子净度,通过加工把夹杂在种子里的杂草种子,植物茎叶,未熟种子,受病虫和机械损伤的种子,以及其它夹杂物清除出去;二是进行种子分级。主要是利用种子物理性状的不同,按种子宽度、厚度、长度和比重的不同进行分级;三是进行种子处理,根据不同作物种子的需要进行种子拌药和包衣处理等。种子精选加工,要经过不同的加工工序,才能达到满意的结果,工序和
Carrying out seed processing is an important measure for seed companies to seek quality first and increase economic benefits. It is an important measure to improve seed quality, reduce seed consumption, save cost, standardize seed quality, provide commercialization and serve socialization. The purpose of seed processing has three aspects: First, improve the clarity of seeds, by processing to weed seeds, plant stems and leaves, unripe seeds, seeds damaged by pests, diseases and machinery, and other inclusions; Is to seed classification. The main is the use of seed different physical properties, according to the seed width, thickness, length and specific gravity grading; third is the seed treatment, according to the needs of different crop seeds for seed dressing and coating treatment. Seed selection processing, to go through different processing operations, in order to achieve satisfactory results, processes and
