不同质量比的双吉尔—GGR6号浸种油松育苗试验

Seed Soaking Chinese Pine Nursery Stock Test by Using GGR6 of Different Density

采用质量比为20mg/kg,40mg/kg的双吉尔—GGR6号的植物生长调节剂浸种油松育苗,结果表明,对苗木生长有显著的促进作用,但两种质量比之间增益效果无明显差异,后者的用药量比前者多1倍。认为采用质量比为20mg/kg的双吉尔—GGR6号植物生长调节剂育苗,可以提高苗木生长量,降低成本。

Adopting plant growth regulator of GGR6, whose density is 20 mg/kg, 40 mg/kg, to seed soaking Chinese ping, result shown GGR6 seed soaking Chinese ping can promote the growth of nursery stock, but there is no distinct deference for the gain result between two kinds of density, but use dosage of GGR6 40 mg/kg is more one times than GGR6 20 mg/kg. We think that GGR6 20 mg/kg can increase growing quantity of nursery stock and reduce cost.
