应用2000,1000,500,250,125,62mLL-1TMS天目丝增抗剂对200株长白落叶松苗进行6小时浸根,在生长季节(5月30日至10月20日)对经过天目丝增抗剂处理的造林苗每隔15天测定一次苗木的高生长、地径、主根长度,侧根数。实验结果表明,天目丝增抗剂处理可以极大地促进长白山落叶松苗木生长并能提高苗木质量。500mLL-1TMS处理的苗木生长效果最好,与常规育苗相比,高生长平均增加42.5%,地径生长平均增加30.7%,主根长平均增加14.0%,侧根数平均增加31.6%;Ⅰ级苗和Ⅱ级苗各占一半,没有Ⅲ级苗,显著地提高了经济效益。表3参8。
200 strains of Changbai larch seedlings were immersed in roots for 6 hours with 2000, 1000, 500, 250, 125, 62mLL-1 TMS Tianmu slippage enhancer. After the growth season (May 30th to October 20th) Planting seedlings measured once every 15 days seedling height growth, diameter, length of the main root, lateral root number. The experimental results showed that the treatment with Tianmuosi agent could greatly promote the growth of larch seedlings in Changbai Mountain and improve the seedling quality. 500mLL-1TMS had the best growth effect on nursery stock. Compared with the conventional nursery, the height growth increased by 42.5% on average, the average diameter growth increased by 30.7%, the average length of main roots increased by 14.0% and the number of lateral roots increased by 31.6% Ⅱ half seedlings each, there is no Ⅲ seedlings, significantly increased economic efficiency.
