福建省建瓯市小桥镇上屯村,采用不同扦插时间(4月15日、5月15日、6月15日)、不同圃地(培育2 a杉木扦插苗的圃地、经过1 a水稻轮作的圃地)进行杉木优良无性系扦插育苗试验。结果表明:4月、5月扦插的杉木优良无性系苗木质量及苗木成活率均显著高于6月,其中4月扦插的苗木质量最优。在相同的扦插时间下,经过轮作的圃地苗木生长质量明显优于未轮作的圃地苗木生长质量。由此,建议福建杉木优良无性系扦插育苗时间应于4月,选择经过轮作的圃地进行扦插育苗有利于提高苗木质量。
In Shangtun Village, Xiaoqiao Town, Jian’ou City, Fujian Province, different cutting times (April 15, May 15, June 15) and nursery grounds Rice rotation of the nursery) fine clones of Chinese fir cuttings. The results showed that the quality of seedlings and the seedling survival rate of the superior clones of Cunninghamia lanceolata cuttings in April and May were significantly higher than in June, of which the quality of cutting seedlings in April was the best. Under the same cutting time, the growth quality of nursery seedlings after rotation was obviously better than that of nursery seedlings without rotation. Therefore, it is suggested that the fine clonal propagation of Chinese Fir should be in April and the choice of cuttage seedling nursery is conducive to raising seedling quality.
