萌芽培土及不同除萌方式对杉木生长的影响

Effect of Hilling on Cunninghamia lanceolata Sprouting Seedlings and Different Bud-eliminafion Modes on its Growth Conditions

通过对杉木萌芽条培土采用3种不同除萌方式进行试验,并于试验后1年和4年成林后进行数据对比,探讨杉木迹地萌芽条萌芽生长状况。试验表明:萌芽条培土和除萌方式之间对杉木萌芽条的生长状况未发现交互影响。在采伐的次年萌芽条培土和不培土相比,杉木萌芽条的生长差异达到极显著,培土对萌芽条的生长极为有利。人工2次除萌、1次除萌和不除萌3种方式对杉木萌芽条的生长有极显著差异,2次除萌对促进杉木萌芽条的生长最为有利,1次除萌的效果次之,不进行除萌的效果最差。

Experiments were carried out to determine the germination and growth of buds of Cunninghamia lanceolata through the experiment of cultivating shoots of Cunninghamia lanceolata with or without three different ways of de-emergence and comparing the data after 1 a and 4 a of afforestation.Experiment shows that there is no interaction between the sprouting zone the de-emergence mode on the growth status of Cunninghamia lanceolatasprouting zone.During the harvesting of the following year,the differences in the growth of the buds of Cunninghamia lanceolata are significantly different from those of the uncultivated soil.The growth of the buds was extremely beneficial to the growth of the buds.The artificial two-time bud-elimination,one-time bud-elimination and the bud diselimination have significant differences in growth of sprouts of Cunninghamia lanceolata.The second bud-elimination is the most beneficial to promote the growth of Cunninghamia lanceolata.The effect of one-time bud-elimination is the second,and the effect of bud diselimination is the worst.
