Problems solved by technology

Or carry out the overwintering conservation work of water peanuts locally, but whether it is introduction or conservation, the control cost will be increased, and a large number of deaths of water peanut leaf beetles will be caused during transportation. Therefore, it is necessary to seek a simple operation and low cost. It is particularly important to reduce the cost and effectively prevent and control water peanuts.

Embodiment 1

[0027] This experiment was carried out in the orange orchard of Qingshen County, Chengdu, Sichuan.

[0028] Treatment of 1 single species of snakeberry to control terrestrial water peanut

[0029] The snakeberry is collected in the wild, and the stem of the snakeberry is cut into sections with a length of 10-20cm, and each stem section has 1-2 nodes.

[0030] Firstly, the terrestrial water peanuts and other weeds in the orchard are manually cleared, and the land is properly leveled, and then snakeberries are planted.

[0031] The present invention adopts the cuttage mode to plant snakeberry (although it can also be sown by snakeberry seeds, but because the early stage snakeberry grows slowly, the growth rate is far lower than the growth of terrestrial water peanuts, so it is not suitable to adopt the sowing method for planting.)

[0032] The cutting depth of snakeberry is 3-5cm, and the distance between cuttings is 10-20cm. Ensure that the nodes of each stem segment are in co...

Abstract

The invention relates to a biological invasion prevention and control method, in particular to a method for synergistically controlling terrestrial water peanuts by means of plant substitution control and natural enemies. The natural enemy of water peanut, the two synergistically control water peanut. The method of the present invention does not use herbicides, can effectively reduce the occurrence density of terrestrial water peanuts, and the single feeding habit of water peanuts will not cause a new round of ecological hazards, and the perennial snakeberry can realize the control of terrestrial water peanuts. The continuous control of peanuts does not affect the agricultural activities of crop planting. The shallow root system does not compete with the planted crops for nutrients and water. It also has certain medicinal value and can be developed as a traditional Chinese medicine and has a certain ornamental value.

Description

technical field [0001] The invention relates to a method for preventing and controlling biological invasion, in particular to a method for synergistically controlling terrestrial water peanuts by means of plant substitution control and natural enemies. Background technique [0002] Organisms invade another new environment from the original living place through natural or man-made ways, causing economic losses or ecological disasters to the biodiversity, agriculture, forestry, animal husbandry and fishery production and human health of the invaded place (Wan Fanghao, Guo Jianying, Wang Dehui . Hazards and management strategies of alien invasive organisms in China [J]. Biodiversity, 2002, 10(1): 119-125.), that is, biological invasion. With the integration of the global economy, international and domestic trade exchanges are becoming more and more frequent, and the probability of successful biological invasion is also greatly increased. The invasion of plants has caused great ...
