Problems solved by technology

At present, the main measures of chemical control, natural enemy resource utilization and prevention, and manual removal and control of Mikania micrantha can achieve certain effects, but they can only treat the symptoms but not the root cause, and Mikania micrantha is very easy to relapse and spread.
[0003] Although a Chinese patent discloses "A method for controlling Mikania micrantha by means of alternative control combined with herbicide application" (201210533086), sweet potato Ipomoea batatas Combining the herbicide "Bencao Song" to prevent and control Mikania micrantha, after all, the suitable planting areas for sweet potatoes are mostly agricultural land, and they are relatively fertile cultivated land, while mountainous and raw land are not easy to plant, and the suitable range of sweet potatoes is narrow, and the ability to continuously control Mikania micrantha is limited , the vines will wither in winter and need to be constantly replanted, which brings certain difficulties to the control of Mikania micrantha; another Chinese patent discloses "a method for completely curbing the growth of new individuals of the vicious weed Mikania micrantha" (200510033305), which also Involving Mikania micrantha as an alternative control, the choice was the Umbrella Maple Heteropanax fragrans Alternative control of Mikania micrantha, although the Umbrella Maple can control Mikania micrantha to a certain extent, after all its greatest value is ornamental value, it belongs to landscape garden plants, large-scale application of alternative control of Mikania micrantha, its cost investment is relatively large, it is difficult to popularize and apply

Embodiment 1

[0016] In April 2008, selected annual high-quality Bamboo basilica seedlings and planted them in the following area according to the row spacing of 5m×6m: an abandoned and abandoned area of ​​20 mu located next to the Longrui Highway (the demonstration site of the Mikania project of the Yunnan Academy of Forestry Sciences) On the slopes, the dominant plant is Mikania micrantha, with an average coverage of 90%, an altitude of 800m, and a slope of 30°. It belongs to the subtropical monsoon area controlled by the Indian Ocean monsoon. The dry and wet seasons are obvious, the annual average temperature is 21°C, and the annual average rainfall is 1402.1mm; The soil is loose, mostly red soil, which is completely suitable for the growth of Mikania micrantha; the base fertilizer is applied in the year of planting, and the most fertilized at the end of each year thereafter. In the first three years after planting, the seedlings of dragon bamboo are tended artificially, and the weeds aro...

Embodiment 2

[0019] Select annual high-quality sweet dragon bamboo seedlings and plant them in the following areas according to the row spacing of 3m×4m: the average annual temperature is 17°C, the effective accumulated temperature is not lower than 10°C at 5600°C, the extreme minimum temperature is -4°C, and the frost-free period is 320°C. It is 70cm thick, loose and fertile red soil land, the terrain is valley, and Mikania micrantha grows. With the cultivation and growth of sweet dragon bamboo year by year, the canopy density of dragon bamboo will reach 30% after one year; 60% after two years; and 90% after three years. Mikania micrantha, on the contrary, has an initial coverage of 80%, a year later, the coverage is 50%, two years later, the coverage is 28%, and three years later, the coverage is 0%. Bamboo shoots began to be produced two years after planting. The output increased sharply in the third year and gradually stabilized after the fourth year.

Abstract

The invention provides a method for replacing and controlling mikania micrantha by dendrocalamus brandisii. The method for replacing and controlling the mikania micrantha by the dendrocalamus brandisii is characterized by comprising the steps that the dendrocalamus brandisii is planted on an area where the mikania micrantha grows and the dendrocalamus brandisii can be grown according to the row spacing and line spacing of 3-6 m * 4-6 m, the dendrocalamus brandisii is cultivated for two to three years, and then the dendrocalamus brandisii can gradually replace the mikania micrantha to grow and spread until the mikania micrantha is completely restrained. According to the method for controlling the mikania micrantha, in addition to being capable of completely restraining the growth of the mikania micrantha and controlling spreading of the mikania micrantha, the bamboo wood, the bamboo shoots and the processed products of the dendrocalamus brandisii can further be harvested; the advantages of being environmentally friendly, small in investment, quick in effect, simple and easy to achieve, easy to learn and command and easy to popularize are achieved, the ecological benefits and ornamental value are obvious, production and income increasing can be promoted, and the land utilization rate is improved.

Description

technical field [0001] The invention relates to a method for controlling Mikania micrantha by using Bamboo burgundy as an alternative and belongs to the technical field of pest ecological control. Background technique [0002] Mikania ( Mikania micrantha H.B.K.) is a perennial herbaceous vine of the genus Eupatorium in the Compositae family. In 2004, the International Union for Conservation of Nature (IUCN) announced that it was one of the 100 most invasive alien species in the world. On January 9, 2013, it was once again identified as the only national forestry quarantine harmful plant by the Chinese government announcement. At present, the main measures of chemical control, natural enemy resource utilization and control, and manual removal and control of Mikania micrantha can achieve certain effects, but they only treat the symptoms but not the root cause, and Mikania micrantha is very easy to relapse and spread. [0003] Although a Chinese patent discloses "A method for...
