摘要：在福建邵武地区杉木无性系采穗圃中，对４～６年生的采穗母株进行了连续３ａ的定株观测，以了解不同处理下母株萌芽、生长规律，并进行了采穗圃施肥初步试验。结果表明：采穗母株萌芽发生有较强的规律性，８月下旬全面清条后，９月为孕芽期，１０月为芽条速生期，１１月为芽条生长缓慢期，直至停止生长。母株全年萌生能力最强为４～５月，其次为８～９月；而萌条生长速度较快在６～７月，９月次之，且与月均温相关密切。施肥试验结果表明：施尿素与施复合肥均比对照显著增产，且两肥种的增产效应无显著差异；以３月初和８月底两次施肥效果最好，全年四次产条量总的增产率为５４．０％～５６．９％，每次施用量以每公顷１８７．５～２２５ｋｇ的尿素或复合肥为宜。根据采穗母株的萌生规律，以及已有的树体管理、土肥管理理论和实践，提出了“一年三采三插三管”的采穗圃管理制度。
In vegetative propagation nursery of Chinese fir,in Shaowu region of Fujian Province,the cutting donor plant of 4～6 years were observed with fixed plant for 3 years,as that growth and development law of cutting donor plant were known in different working methods of coppice shoots,and preliminary effect of fertilization were studied.The results showed:there were very strong law on growth and development of sprout of cutting donor plant.After all clearing away coppice shoots in late August,September was pregnant bud period,October was period for quickly growing of coppice shoots,November was period for slowly growing of coppice shoots,until growing stopped.The ability of sprouting of donor plant was very strong in April and May.Second were in August and September.But the growing speed of coppice shoots was more quickly in June and July,and the second was Septemer,and the correlation was close between month average temperature and growing speed of coppice shoots.For the fertilization experiment,the results showed:there were significant increasing yields fertilizing urea and multiple fertilizer than CK,there were no significant difference in increasing production effect between two fertilization special,the best effects of fertilization were on early March and late August for two times,increasing rate of total coppice shoots were 54.0%～56.9% in a year, and fertilizing quantities of urea or multiple fertilizer 187.5～225 kg/hm 2 were adaptable every time.According to sprouting law of cutting donor plant and there were theory and practice of stock plant management and fertilizer and soil management,“three times cutting coppice shoots,three times cutting,three times management in a year” management regulation of vegetative propogation nursery were mentioned.
