摘　　要：【目的】以木地肤(Kochia prostrata)种子为研究对象,筛选适于木地肤种子包衣处理的粘结、吸水及填充材料的种类及添加水平,提高木地肤种子的萌发率和种用价值。【方法】采用包衣处理,筛选出粘结材料、高分子吸水材料以及填充材料对木地肤种子萌发表现较好的处理,采用三因素四水平的正交试验法进行木地肤包衣种子试验配合比筛选,得出最优的包衣配比。【结果】木地肤的种子包衣,粘结材料优选顺序为0.2%阿拉伯胶,0.1%聚乙烯醇,0.1%羧甲基纤维素钠,0.1%壳聚糖;吸水材料优选顺序为种药比17%、14%、11%;填充材料优选顺序为硅藻土、蛭石、高岭土+蛭石。【结论】对木地肤包衣种子发芽率的影响因素从大到小排列为,吸水材料>填充材料>粘结材料,最优组合为0.1%羧甲基纤维素钠×17%吸水剂×硅藻土。【Objective】Based on the research object of Kochia prostrata seed,the kinds and adding levels of bonding,water absorption and filling materials sui Table for the seed coating treatment were selected to improve the germination rate and seed value.【Method】Through coating treatment,the bonding material,high-molecular water-absorbent material and filling material were screened for better performance of K.prostrata seeds germination,and then the orthogonal test method of three factors and four levels was used to screen the optimal coating ratio.【Result】The preferred order of bonding material for seed coating of K.prostrata was 0.2%Arabic gum,0.1%polyvinyl alcohol,0.1%sodium carboxymethyl cellulose,0.1%chitosan;the preferred order of water-absorbing material was seed medicine.The ratio was 17%,14%,11%;the preferred order of filling materials is diatomite,vermiculite,kaolin+vermiculite.【Conclusion】The influencing factors on the germination rate of K.prostratacoated seeds are arranged in ascending order as follows:water-absorbing material>filling material>bonding material;the optimal combination is 0.1%sodium carboxymethyl cellulose×17%water-absorbing agent×diatomite.
