摘要
试验表明,油松容器育苗播种前采用GGR6号植物生长调节剂进行浸种催芽处理,可使油松提早出苗2～3 d,苗全期提前4～7 d;苗高年生长量增加66.4%～151.9%,地径生长量增加71.9%～159.9%,地上、地下部鲜重分别增加2～2.3倍和3～3.2倍.其中处理1对油松出苗率、苗木鲜重及根系的促进作用优于处理2,而对苗高、地径生长的促进作用低于处理2.
Growth regulators of plant were used to treat seeds and seedlings in growth period. The results show that to soak seeds and to spray young seedlings with regulators are effective. Using regulator GGR6 to treat seeds can come out of seedling 2-3 days ahead and have all seedlings period 4-7 days ahead. Growth increase 66. 4% and 71.8% at growth of height and growth of base diameter. Weight of the stem and leaves increases 2.3 times. Weight of roots increases 3.2 times.
