在苗木起苗时,根系大部分被切断。如柳杉播种苗,将失去全根量的60％(乾重),赤松要失去90％。这些根量的减少明显地影响着苗木成活和其以后的吸收作用。为了使起苗后苗木成活并进行顺利生长,必须较好地保持移植苗木的生理条件,这可从两方面考虑:其一,苗木尤其是根系组织的再生;其二,是再生组织有恢复个体活
Most of the roots are cut off when the seedlings start to grow. If cedar sown, will lose 60% of the total amount (dry weight), Aconitum to lose 90%. Decreasing these root weights significantly affects seedling survival and its subsequent uptake. In order to make seedlings survive after seedling and smooth growth, we must better maintain the physiological conditions of seedlings transplanted, which can be considered from two aspects: First, the seedlings, especially the regeneration of root tissue; the second is the regenerative tissue restoration of individuals live
