Ageratina adenophora water culture method

Abstract

The invention relates to an ageratina adenophora water culture method which comprises the following steps: 1, sprouting seeds, namely culturing disinfected ageratina adenophora seeds into seedlings in an incubator; 2, making a culturing device; 3, transplanting the seedlings, namely placing the seedings obtained in the step 1 into the culturing device obtained in the step 2; 4, culturing the seedlings, namely placing one second time of water culture nutrient solution into the culturing device, replacing with 1 time of water culture nutrient solution to continuously culture after culturing for 9 days, and replacing the nutrient solution at intervals of 3 days. The method is convenient to obtain the consistent and high-quality water-cultured seedlings and can provide reliable material resources for search on the aspects of invasive mechanism, chemical and biological prevention and treatment, molecular biology, physiological ecology and the like of ageratina adenophora.

Description

1. Technical field: [0001] The method of the invention relates to a hydroponic method of Eupatorium adenophorum. 2. Background technology: [0002] Eupatorium adenophorum (Eupatorium adenophorum Spreng) is a worldwide malignant weed, which is a clustered semi-shrub perennial herb of the genus Eupatorium adenophorum in the family Asteraceae. At present, it has been widely distributed in Yunnan, Guizhou, Sichuan, Guangxi, Tibet and other places. It has spread and caused disasters in the invaded areas, causing serious harm to the local ecological environment, economic development and human health. It has become a malignant weed and has grown to be difficult to control. Degree. According to reports, there is no effective method to completely control Eupatorium adenophorum, and the mechanism of rapid spread of Eupatorium adenophorum is not very clear. Therefore, it is particularly important to strengthen the research on the invasion mechanism, chemical and biological control, m...

Problems solved by technology

[0004] 1. It is difficult to recover the complete root system from the samples of the soil culture medium, which is not conducive to the requirements of some studies on the root system of Eupatorium adenophorum. At the same time, because the root system is stuck in the soil, the aeration is poor, and the soil is easy to compact, resulting in too long experiment time or experimental results. not obvious

[0005] 2. In the soil culture medium, the root system of Eupatorium adenophorum is easy to rot, and it is difficult to obtain uniform experimental materials, which causes large errors in the experiment

[0006] 3. As a vicious invasive weed, the cultivation site of Eupatorium adenophorum must be strictly controlled. Soil cultivation may cause seeds and rooted branches to spread outside, causing potential harm to the external environment
