Embodiment Construction

[0012] (1) Model fitting:

[0013] In August and September of 2010 and 2011, the height (H) and cap diameter (D) of macrofungi were measured with a steel tape measure in the field; the fruiting bodies were carefully harvested, and the litter and root soil adhered to the surface were removed, and put into the belt There is a kraft paper bag with desiccant, and the fruiting body is transported back to the laboratory within 1 day, dried at 65° for 24 hours, and the dry weight of the fruiting body is measured, that is, the biomass. A total of 8622 macrofungi were surveyed, 53 species belonged to 13 families.

[0014] use the formula Calculate the cap area (S); take the biomass (B) as the dependent variable, the macrofungi height (H) and the cap area (S) as the independent variables to fit the general linear model between H, S and B, and get Formula: log 10 B=-1.753+0.835log 10 S+0.16log 10 H(R 2 =0.724, F=768.466, p<0.001).

[0015] Further, according to the physiological ...

Abstract

The invention mainly relates to a method for briefly investigating the biomass of a macro fungus, belonging to a technology for investigating the diversity of a macro fungus. The method provided by the invention solves the problems of high difficulty, big error, high damage possibility of macro fungus resources and the like in the existing biomass determination process of a macro fungus, and is characterized by being a method which can be used for estimating the biomass of a macro fungus according to the height of the macro fungus and the area of the pileus without the collection of sporophores. By measuring the height (H) and the pileus diameter (D) of one macro fungus, the biomass can be estimated according to the following formula: log10B=-1.753+0.835log10S+0.16log10H (R2=0.724, F=768.466, and p<0.001), wherein S can be calculated according to a formula shown in the specification, and labor and material resources can be saved; and the macro fungus can be further divided into a mycorrhiza fungus and a saprophytic fungus, and the biomass of each fungus can be respectively estimated according to the following formulae: log10B=-1.035+0.426log10S+0.606log10H (R2=0.840, F=168.080, and p<0.001) and log10B=-1.679+0.665log10S+0.318log10H (R2=0.785, F=423.269, and p<0.001); and the estimation precision is enhanced. Thus, the method provided by the invention is simple and easy to implement, has high estimation precision, protects the macro fungus resources and can be used in the investigation and study on the diversity of the macro fungus.

Description

1. Technical field [0001] The invention relates to a method for investigating the diversity of macrofungi, in particular to the measurement of the biomass of macrofungi in diversity investigation. 2. Background technology [0002] Macrofungi are an important part of understory microorganisms. Their saprophytes can decompose understory litter, and mycorrhizal fungi can form mycorrhiza with plant roots to promote the absorption of water and nutrients by host plants. Therefore, macrofungi play an important role in maintaining the nutrient cycle in the ecosystem, and their diversity investigation is also one of the important contents of ecological research, which has attracted much attention. [0003] The method of investigating the diversity of macrofungi in my country is initially based on the number of species, which is relatively inaccurate. Later, on the basis of the number of species, some scholars added indicators such as relative density (number), relative abundance, re...
