摘  要：
以保水剂、吲哚丁酸、赤霉素和代森锰锌作为主要因素,用正交试验的方法组合配方,对紫花苜蓿种子进行包衣试验筛选出最佳方案。结果表明:紫花苜蓿包衣后,虽然发芽率、发芽势和简化活力指数较对照降低,但有效提高了田间出苗率,降低了霉变率和霉变指数。因此,紫花苜蓿包衣后会提高种子的成活质量。就苗体素质来看,包衣提高了苗高、鲜重和干重,有效促进了地上部分生长,增加了生物量;综合评价后,A、B、C、D 4种因素对包衣种子的配方组成之间差异无显著性。但就分析结果来说,各因素对包衣配方的影响大小顺序为B>A>D>C,即吲哚丁酸>保水剂>代森锰锌>赤霉素,结合选用药剂比例选定最佳紫花苜蓿包衣配方是A2B1C3D1。

摘  要：
Took aquasorb,IBA,GA and mancozeb as a major factor,by orthogonal way combination formula,alfalfa was selected for the pilot coating to choice the best option.Orthogonal test results showed that the analysis of variance:Alfalfa coating,although the germination rate,germination energy and vitality to simplify the index lower than that of control,but effective to increase the germination rate in the field,reducing the rate of mold and mildew index.As a result,alfalfa seed coating will improve the quality of survival.Miller on the quality of the body,the coating to increase the height,fresh weight and dry weight,effectively promoted the growth of some of the ground,an increase of biomass;After the comprehensive evaluation,A,B,C,D four factors on the seed coating between the components of the formula was no significant difference.However,on the results of the analysis was,various factors on the coating formula for the impact of the size of the order of B> A> D>C,that was,IBA> aquasorb>mancozeb> GA.Combined ratio of pharmacy selected the best selection of alfalfa coating formula was A2B1C3D1.
