Problems solved by technology

[0003] However, traditional lead detection methods require a large number of instruments and equipment, high technical requirements, complicated operation, and high cost. At present, there is a lack of an indicator plant in the market that can intuitively, conveniently, economically and quickly indicate whether the lead content in the environment exceeds the standard.

Embodiment 1

[0029] A method for cultivating scallions, the cultivating method comprising the following steps in sequence:

[0030] 1) Picking the mature seeds of scallops, air-drying and threshing naturally, and screening out the plump and strong seeds;

[0031] 2) Take the seeds and store them away from light by immersion in water, and the storage period is more than 100 days;

[0032] It has been verified by experiments that the mature seeds of Daxue stored by water immersion have the highest germination rate and are easy to operate. As can be seen from Table 1, the germination rates of different storage methods are similar at the initial stages of seeds, which are generally not high; the difference is that the water immersion method significantly increases the germination rate over time, between 150--350 days (the experiment ends here, The germination rate may be kept for a longer period of time), and it maintains its 100% germination rate; the shade drying method, that is, the seeds ...

Embodiment 2

[0043] Embodiment 2: A kind of method adopting the method for measuring lead exceeding the standard of scallions, adopting the scallions cultivated by the cultivation method of embodiment 1, the steps are as follows:

[0044] 1) Take 30 to 50 healthy plants of the third-generation Sorrel and place them on the floating island, and place them in the water area to be monitored;

[0045] 2) When the lead content in the water body exceeds 0.03mg / L, after 2-3 hours, the new root system of the scallop will first change color, and then the leaves will turn yellow and light due to the obstruction of photosynthesis and respiration, and further, the new root will stagnate. or death, and the degree of harm increased with the increase of lead concentration;

[0046] 3) if figure 1 As shown, if any abnormalities are found in the new roots of Daleia sativa, water samples shall be taken immediately according to the regulations for testing to monitor whether the lead content in the water syst...

Abstract

The invention relates to a Pistia stratiotes culture method and a method for monitoring lead exceeding by adopting Pistia stratiotes, belongs to the technical field of environmental protection engineering and relates to a propagation and ecological restoration technology for plants which are sensitive to lead and can enrich lead. The Pistia stratiotes culture method and the method for monitoring the lead exceeding by adopting the Pistia stratiotes sequentially comprise the steps of picking mature Pistia stratiotes seeds, taking seeds which are stored for over 100 days by a water soaking method, carrying out asexual propagation one week after the natural germination of the seeds, continuously clearing maternal plants of first and second generations, reserving robust plants of a third generation, and then, placing the Pistia stratiotes of the third generation in floating islands and water areas to be monitored. According to the method, whether the lead content of water of river courses is overproof or not can be displayed in a direct-viewing, convenient, economical and rapid manner.

Description

technical field [0001] The invention relates to a method for cultivating scallions and a method for measuring lead exceeding the standard by using the scallions, belonging to the technical field of environmental protection engineering, and relates to a breeding and ecological restoration technology for plants that are sensitive to lead and can be enriched. Background technique [0002] With the continuous development of the economy, the intensity of resource utilization has increased, and the ecological system has continued to degrade, and environmental pollution has become increasingly serious. Among them, heavy metal pollution has become one of the global environmental problems. Lead is one of the heavy metals. The poison of lead to the human body is cumulative, mainly harming the brain and nervous system of the human body, especially for children. Because lead in water, soil, and air is absorbed by organisms and transferred to organisms, especially fish will enrich a larg...
