杉木育苗现行有几种方法,现分别介绍和评述如下:一、遮光育苗:杉木属于半阴性树种,生长在阳坡、干燥地区的杉木,往往早熟。幼苗最宜在日照短、直射光不强的环境里生长,出土不久的幼苗在烈日照射土温较高的情况下,根茎处皮层会被灼伤而干缩,输导系统被切断,导致苗木枯死。为安全渡过高温季节,架设透光度为20%左右的荫棚,以创造较为适宜的凉爽环境,此法袭用已久,也确有成效。 Cunninghamia lanceolata nursery current there are several ways, are introduced and reviewed respectively as follows: First, shading nursery: fir is a semi-negative tree species, growing in the sunny slopes, dry areas of the fir, often precocious. Seedlings are best in the short sunshine, direct sunlight is not strong growth in the environment, shortly after the emergence of young seedlings in the hot sun high soil temperature, the cortex at the roots will be burned and shrinkage, the conduction system is cut off, leading to seedlings dead . To safely weather the hot season, erection of shade of about 20% shade to create a more appropriate cool environment, this method has been used for a long time, but also indeed effective.
