摘要
文章采用随机区组试验设计,应用盆栽土培试验方法,用GGR、IBA、PP333分别配制成20×10^(-6),40×10^(-6),80×10^(-6),160×10^(-6)4种浓度的溶液,对大叶栎幼苗进行定期的整株喷施,以清水喷施为对照。定期测定其地径,并记录数据。试验结果表明:GGR20×10^(-6),GGR40×10^(-6),IBA20×10^(-6)处理对大叶栎幼苗地径生长影响较为显著。
The study adopts randomized block experimental design and pot cultivation experiment method. The solution with the respective concentration of 20×10-6, 40×10-6, 80×10-6 and 160 ×10-06 is formulated by GGR, IBA and PP333, which is sprayed regularly on the whole castanopsis fissa seeding. The findings are compared with those sprayed by clear water. Their ground diameters are regularly measured and recorded. The results show that GGR20×10-6, GGR40×10-6 and IBA20×10-6 have more significant effects of the ground diameter gowth.
