Rhizomatous plant species eliminating method

Abstract

The invention discloses a rhizomatous plant species eliminating method and belongs to the technical field of ecological remediation. The rhizomatous plant species eliminating method comprises droppingchemicals into petioles of rhizomatous plant species to be eliminated to infiltrate the chemicals into rhizomatous tubers via conduits and then supplementing chemical drops to achieve the aim of completely eliminating unwanted rhizomatous plant species. The rhizomatous plant species eliminating method can rapidly and easily eliminate the rhizomatous plant species and meanwhile avoid damaging wanted rhizomatous plant species, and also, is low in weeding chemical consumption, free from pollution to ambient environment, safe, reliable, simple in operation, efficient in labor and reduced in cost.

Description

technical field

[0001] The invention relates to a method for eradicating underground stem plant varieties, and belongs to the technical field of ecological restoration. Background technique

[0002] Ecological restoration is currently the mainstream technology for river management, and the construction of a complete aquatic plant system is an integral part of it. Aquatic plants have a strong absorption and utilization of nitrogen and phosphorus. At the same time, the well-developed root system takes root in the bottom mud, prevents the bottom mud from floating, and controls the release of endogenous nutrients. It is an effective way to control, regulate and inhibit the eutrophication of water bodies. , and at the same time cooperate with ecological artificial wetlands, floating beds and revetments to greatly enhance the landscape effect. However, different plants have very different removal effects on nitrogen and phosphorus, and different species of the same plant have obv...

Examples

Embodiment 1

[0023] Mix the herbicide 2-methyl-4-chloric acid and isooctyl fluroxypyr at a ratio of 1:10, drop 1 / 2 of the recommended dosage into the center of the lotus petiole, and then transport water through its hollow structure The catheter flows to the underground stems, and after 7 days, it is found that more than 90% of the total lotus species that do not need miscellaneous goods have completely withered and died; at the same time, continue to drip medicine to the remaining 10% lotus species that have not been dripped with medicine, and continue to eradicate unnecessary lotus species. After this medicine drop, all the lotus species that are not needed can be completely eradicated, while other lotus species that are needed are growing well.

Embodiment 2

[0025] Mix the herbicide 2-methyl-4-chloric acid and fluroxypyr at a ratio of 1:15, drop 7 / 12 of the recommended dosage into the center of the lotus flower stalk, and then pass through the hollow structure of the water conduit After 10 days, it was found that more than 95% of the total lotus flowers that do not need miscellaneous goods have completely withered and died; at the same time, continue to drip medicine to the remaining 5% lotus miscellaneous varieties that have not been dripped with medicine, and continue to eradicate unnecessary lotus varieties. This time, all the lotus species that were not needed were completely eradicated, while other lotus species that were needed were growing well.

Embodiment 3

[0027] After mixing the herbicide 2-methyl-4-chloroacid and 2-methyl-4-chloroisooctyl at a ratio of 1:19, drop 2 / 3 of the recommended dosage into the center of the lotus petiole, and then pass through the hollow structure The water conduit flows to the underground stems, and after 5 days, it is found that more than 92% of the total lotus flowers that are not needed have completely withered and died; at the same time, continue to drip medicine on the remaining 8% lotus varieties that have not been dripped with medicine, and continue to eradicate unnecessary lotuses varieties, after this drop of medicine, all lotus varieties that are not needed can be completely eradicated, while other lotus varieties that are needed are growing well.
