Control method for invasive plant bidens pilosa L. and application

Abstract

The invention discloses a control method for invasive plants and application, especially control on bidens pilosa L. According to the method, plant straw is uniformly laid on a ground surface where invasive plants grow in winter; after continuous 30-80 days or spring begins, light-proof airtight materials including a black film and the like are laid to guarantee that the covering rate is 100%; andthe black film continuously covers the plant straw for 50-70 days or is removed after summer begins. According to the scheme, two ways of straw covering and film covering are combined in a specific sequence and specific time to perform stacking continuous covering, and thus, a significant control effect on invasive weeds, such as bidens pilosa L. and the like, is significant; moreover, not only can the bidens pilosa L. above the ground be eliminated, but also underground rhizomes and seeds thereof can be further killed, inactivated and reduced, so that the control effect is more lasting; meanwhile, soil fertility can also be enhanced after the straw, the bidens pilosa L. and the like decompose; and in addition, by employing the technical scheme of the invention, mechanical weeding is notneeded, labor intensity is low, cost is low, environmental pollution is not generated, the straw can also be recycled, and the application prospect is good.

Description

technical field [0001] The invention belongs to the technical field of ecological prevention and control, and relates to a control method and application of the invasive plant P. trifolii, more specifically, to a method and application for controlling P. trifolii by continuous superposition and covering of plant straws such as rice and film . Background technique [0002] Bidens pilosa L. is an invasive alien weed. Due to its fast growth and reproduction, tall plants, strong resource competition and allelopathic ability, it is easy to affect the biodiversity and agricultural production of the invaded area. cause serious damage. Invasive plants, such as "wildfire starting a prairie fire", will "overwhelm the host" and replace the original plants, destroying the diversity of the local ecosystem. After most of the alien species have successfully invaded, they grow vigorously. By suppressing or crowding out native species, they form a single-dominant population, endangering th...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to overcome the defects and deficiencies of the existing measures for the prevention and control of the invasive plant P. trifoliate, and to provide a method of using plant straws such as rice and black films to perform continuous overlapping and covering control in a specific time sequence and specific stacking sequence. The method of P. trifolii and other invasive plants has a significant control effect; moreover, this method uses ecologically friendly and efficient prevention and control measures to control invasive alien plants, including the use of three harmful invasive plants. The growth of the weeds dominated by the needle grass can achieve the effect of promoting the reasonable recycling of crop straw and reducing the environmental pollution and waste of resources caused by its improper use.
