Embodiment 1

[0028] First, 25 days after the stem nodes of Mikania micrantha were planted, the plant height of Mikania micrantha was about 8 cm, and stylosias were planted between the micranthas, and 2 stylosia seedlings with a height of 45 cm were planted in each hole, the planting depth was 5 cm, and the row spacing of stylosias was 40×40 cm. The size of the planting experiment area was 5×5m, and the planting ratio of Mikania micrantha and Stylophyllum in the treatment area was 1:1, and each treatment had 5 replicates. After 90 days, the biomass of Mikania micrantha (fresh weight and dry weight), the length of the main stem, and the number of primary branches were measured.

Embodiment 2

[0030]Firstly, 25 days after the stem nodes of Mikania micrantha were planted, the plant height of Mikania micrantha was about 6cm, and stylotypes were planted between the micranthas, and 2 stylotype seedlings with a height of 43cm were planted in each hole. The size of the experimental area was 5×5m, the planting ratio of Mikania micrantha and Stylophyllum in the treatment area was 1:2, and each treatment had 5 replicates. After 90 days, the biomass of Mikania micrantha (fresh weight and dry weight), the length of the main stem, and the number of primary branches were measured.

Embodiment 3

[0032] Firstly, 25 days after the stem nodes of Mikania micrantha were planted, the plant height of Mikania micrantha was about 5cm, and stylotypes were planted between the micranthas, and 3 stylotype seedlings with a height of 40cm were planted in each hole. The size of the experimental area was 5×5m, and the planting ratio of Mikania micrantha and Stylosmanthus in the treatment area was 1:3, and each treatment had 5 replicates. After 90 days, the biomass of Mikania micrantha (fresh weight and dry weight), the length of the main stem, and the number of primary branches were measured.

Abstract

The invention relates to the technical field of ecological control, and discloses a method for replacing and controlling Mikania micrantha H.B.K. by utilizing Stylosanthes guianensias. According to the method, the Stylosanthes guianensias. is planted on land growing with the Mikania micrantha H.B.K.; the growth of the Mikania micrantha H.B.K. can be inhibited by the Stylosanthes guianensias.; andexperiments prove that the fresh weight control effect of the planted Stylosanthes guianensias. on a single plant of the Mikania micrantha H.B.K. can reach 63.01%, the dry weight control effect on theMikania micrantha H.B.K. can reach 68.70%, the main stem length of the Mikania micrantha H.B.K. can be decreased by 81.2%, and the first-stage branching number of the Mikania micrantha H.B.K. can bedecreased by 68.6%.

Description

technical field [0001] The invention relates to the technical field of ecological control, in particular to a method for controlling Mikania micrantha by using stylosa. Background technique [0002] Mikania micrantha H.B.K., native to Central and South America, is a perennial herbaceous vine belonging to the genus Mikania of the family Asteraceae. First discovered in Hong Kong in 1919, it was introduced to the coast of Guangdong in the late 1980s and early 1990s, and gradually spread. The areas that have spread now include Guangdong, Guangxi, Fujian, Hainan, Yunnan, Macao and Taiwan. Mikania micrantha mainly attaches to the plant canopy through the screen cover in a short period of time, affecting plant photosynthesis and normal growth and development, causing plant death, changing species types, and affecting biodiversity. Therefore, Mikania micrantha is also known as a horrible "plant killer", "green cancer" or "ecological invader" in China. Due to its serious ecological...
