Embodiment Construction

[0034] The above and other technical features and advantages of the present invention will be described in more detail below with reference to the accompanying drawings.

[0035] The concrete process of the determination method of the sulfur content of grassland plants of the present invention is:

[0036] Step a, collecting grassland plant samples;

[0037] According to the preset measurement area, select appropriate sampling points and reference points, and select the dominant species / subspecies in each measurement area; dominant species mainly include Achnatherum splendens and Stipa Convolvulus, Sansevieria. Collect plants with similar growth, put them into sampling bags, number and register them.

[0038] Step b, sample processing;

[0039] In summer, sampling in the morning and pretreatment at noon, or sampling in the afternoon, pretreatment on the same day, and do not leave overnight. If the number of samples is too large to be processed on the same day, refrigerate....

Abstract

The invention relates to a method for measuring the sulfur content of steppe plant. The method comprises the specific processes of a, collecting a steppe plant sample; b, treating the sample: b1, cleaning, b2, drying, b3, grinding and b4, smashing; c, measuring the sulfur content of the plant: performing measurement by an acidic wet digestion-barium sulfate turbidimetry, putting the plant sample under the action of a catalyst and an oxidant to oxidize organic sulfur until all sulfurs in the plant are converted into sulfates, then adding a quantitative amount of acid and a turbidity agent to generate barium sulfate suspension, and performing turbidimetry measurement at the wavelength of 440nm; and d, analyzing according to a sulfur content measurement result of the plant. According to the method for measuring the sulfur content of the steppe plant, the sulfur content of the whole plants in dominant species / subdominant species can be measured.

Description

technical field [0001] The invention relates to the field of plant detection, in particular to a method for determining the sulfur content of grassland plants. Background technique [0002] SO 2 become one of the main pollutants emitted by open-pit coal mine production, SO 2 Entering the atmosphere, or falling to the ground, affects the properties of the soil, which in turn have direct or indirect effects on plants. SO 2 Pollution forms a brand new living environment. Sensitive species with low resistance gradually disappear, while resistant species survive and continue to evolve. This pollution stress will change the species composition of the biological community. Generally speaking, the sensitivity of different plants to sulfur dioxide varies greatly. It often shows that broad-leaved trees are more resistant than conifers, evergreen broad-leaved trees are stronger than deciduous broad-leaved trees, and woody plants are more resistant than herbaceous plants. Therefore, ...
