种子加工机械化发展的结果,种子加工厂将为承包户,家庭农场提供经过精选、分级、拌药的种子,供生产直接播用。提前拌药对麦种生命力、药剂防病效果有无不利影响呢?黑龙江省八五二农场从1980年起,经过两年田间试验表明,春小麦种子收获干燥后即行加工处理是完全可行的。试验拌种的药剂、用量、操作规程均按生产常规进行。从春小麦收获后,种子入库(8月下旬)开始至第二年春播前(3月下旬),1980年共分5期拌药处理,1981年每隔一个月拌种一次,共8期。全为药剂干拌种,以当地麦播前拌种处理的做对照。各期拌药后的种子分别用布袋、牛皮纸袋、塑料袋扎口包装存放,结果如下:
As a result of the development of seed processing mechanization, the seed processing plant will provide selected households, graded and mixed seed for contractors and family farms for direct broadcast production. Early mixing of wheat seed vitality, pharmaceutical anti-disease effect with or without adverse effects? Heilongjiang Province 852 farms from 1980 onwards, after two years of field trials show that spring wheat seeds after harvesting processing is feasible. Test dressing seed, dosage, operating procedures are carried out according to production practices. After harvesting from spring wheat, seed storage (from the end of August) until spring sowing of the second year (late March), with five batches of compounding in 1980 and seed dressing once every other month for a total of eight phases in 1981. All for the pharmaceutical dry seed dressing to the local wheat sowing before the seed dressing control. Seeds after the various stages of the pharmaceutical were bag, kraft paper bags, plastic bags Zhakou packaging storage, the results are as follows:
