以保靖黄金茶1号为材料,结合生产中苗圃铺新黄土的措施,研究了GGR7号生根剂对扦插穗条根系发生、扦插茶苗切口愈合与出圃时茶苗株高的影响。结果表明:GGR7号生根剂对茶苗根系发育影响显著,但对根系的伸长生长有一定的抑制作用,同时对茶苗切口愈合以及茶苗出圃时的株高均无显著影响。这说明GGR7号生根剂仅对茶苗根系发育作用较大,对茶苗株高等指标影响较小。
The effects of rooting agent GGR7 on the root growth of cuttings, the cutting healing of cuttage tea seedling and the height of tea seedlings at the time of nursery were studied with the measures of Baojing Golden Tea No. 1 and the new loess shop in nursery production. The results showed that rooting agent GGR7 had a significant effect on the root development of tea seedling, but it had some inhibitory effect on the elongation growth of the tea seedling. Meanwhile, the effect of rooting agent GGR7 on the healing of tea seedling and the plant height of tea seedling had no significant effect. This indicates that GGR7 rooting agent only has a greater effect on the root development of tea seedlings and has less effect on the higher index of tea seedlings.
