垂序商陆的入侵给我国沿海防护林造成了严重危害.本研究在入侵程度相对一致的刺槐林下设置样地,采用物理(刈割、切根)、化学(喷洒无公害除草剂)方法进行控制试验,并以林下紫穗槐发育良好、未进行处理的地段作为对照,探索控制垂序商陆生长的有效方法.结果表明:刈割能快速降低垂序商陆各项生长指标,但次年即恢复至对照水平.1/3切根仅减少了当年地上部分生长量,第3年又恢复至处理前水平,而2/3切根和完全切根处理一次即可有效地清除垂序商陆.精喹禾灵和百草枯仅能杀死其地上部分,次年即恢复至处理前水平,而45g.L-1草甘膦处理的垂序商陆死亡率达到100%,第3年新萌发垂序商陆生长与结实量已明显恢复.紫穗槐发育良好地段的垂序商陆各生长指标始终处于较低的平衡状态.采用紫穗槐替代法是长期控制垂序商陆的有效防治方法.
The invasion of vertical order Phyllostachys pubescens has caused serious damage to the coastal shelterbelts in our country.In this study, we set up plots under the relatively invaded forest of Robinia pseudoacacia, using physical (cutting, cutting) and chemical (spraying polluting herbicide) methods Controlled experiment, the effective way of controlling the growth of Pseudostellaria tabulaeformis was explored with lots of well-developed and untreated Amorpha fruticosa.Results showed that mowing could rapidly decrease the growth index of Pseudostellaria tabaci The following year returned to the control level .1 / 3 cut only reduce the amount of above-ground part of the growth, the third year and returned to pre-treatment levels, and 2/3 cut and complete cutting root treatment can be effective in clearing Pokeweed and paraquat can only kill the aboveground parts, and then return to the pre-treatment level the following year, while the mortality of Pseudostellaria baicalensis combined with 45g.L-1 glyphosate reaches 100% 3 years of new germination penguin growth and yield has been significantly restored. Amorphophallus well-developed lots of the order Pokolhu all the growth indicators are always in a low equilibrium. Amorpha fruticosa alternative method is the long-term control of vertical order Lu effective prevention and treatment methods.
