摘  要：
将不同质量浓度的黄腐酸(50、200、600 mg/L FA)+高吸水树脂+多菌灵以及不同质量浓度的赤霉素(25、50、100 mg/L GA3)+高吸水树脂+多菌灵制作成6种生物种衣剂,对隔年桑种子进行包衣处理。包衣后的桑种子发芽率以及脂肪酸含量、α-淀粉酶活力、幼苗根系活力、可溶性蛋白含量以及出苗率、幼苗根长及幼苗鲜质量均比对照提高,其中赤霉素种衣剂2号(含50 mg/L赤霉素)和黄腐酸种衣剂2号(含200 mg/L黄腐酸)的效果最好:分别使桑种子发芽率提高21%、16%;分别使桑种子萌发时的脂肪酸含量提高79%、63%,α-淀粉酶活力提高34%、30%,根系活力提高82%、55%,可溶性蛋白含量提高5%、12%;分别使出苗率提高27%、29%,幼苗根长提高5%、7%,幼苗鲜质量提高22%、19%。依据试验结果认为,采用生物种衣剂对桑种子进行包衣处理,对桑种子的萌发及幼苗的生长均有一定的促进作用。

摘  要：
In present study,six biological seed coating agents which contained 50,200,and 600 mg/L fulvic acid(FA) or 25,50,and 100 mg /L gibberellic acid(GA3),resin with high water absorption ability,and carbendazol were prepared to treat overyear mulberry seeds.The results showed that the seed germination rate,fatty acid content,α-amylase activity,vigor of the seedlings' root systems,soluble protein content,seedling emergence rate,seedlings' root length,and seedlings' fresh weight were all improved over the control.The seed coatings "GA3 No.2" which contained 50 mg/L GA3 and "FA No.2" which contained 200 mg/L FA had the best effects than the other treatments.They enabled increases of seed germination rate by 21% and 16%,of fatty acid content during germination by 79% and 63%,of α-amylase activity by 34% and 30%,of root system vitality by 82% and 55%,of soluble protein content by 5% and 12%,of seedling emergence rate by 27% and 29%,of seedlings' root length by 5% and 7%,and of seedlings' fresh weight by 22% and 19%,respectively.It is concluded that treatment with biological seed coating agents to mulberry seeds can improve seed germination and seedling growth considerably.
