开展种子机械化加工,是种子公司求得质量第一,增加经济效益的重要措施,也是实现种子质量标准化的重要手段。黑龙江省北部积温较低,特别赶上秋季多雨,种子自然降水就很不利,通过机械加工烘干降水就显得非常重要。烘干精选后的种子发芽率和净度较自然降水的发芽率和净度提高3%～4%,为了节约成本,又要加快种子烘干速度,必须做到以下几方面。 Carrying out seed mechanization processing is an important measure for seed companies to seek quality first and increase economic benefits, and also an important means to standardize seed quality. Heilongjiang Province, the northern part of the lower accumulated temperature, in particular, to catch the rainy autumn, natural precipitation is very detrimental to the seeds, precipitation by mechanical processing is very important. After drying, the seed germination rate and clarity of the selected seeds are increased by 3% ~ 4% compared with the natural precipitation. In order to save costs and speed up the drying speed of the seeds, the following aspects must be achieved.
