Embodiment 1

[0062] Embodiment 1 Miscanth plant suitability evaluation method

[0063] Select Miscanthus germplasm that has grown for more than 3 years and has stable growth as the measurement object. Except for stress resistance, the measurement time is generally arranged in the withering and yellowing period or after the blooming period, and the evaluation is carried out from three aspects of agronomy, quality and stress resistance:

[0064] 1. The scoring criteria for the above three aspects are as follows:

[0065] (1) Agronomic evaluation index and scoring standard of Miscanthus germplasm (Table 1):

[0066] Taking the maximum value of 9 agronomic indicators such as dry matter yield, canopy height, stem height, stem diameter, base diameter, tiller number, leaf-to-stem ratio, withered yellowness, and deciduousness of miscanthus as reference values, the scoring standard was formulated:

[0067] ①Dry matter output: unit t·hm- 2 , score=(yield / 35)×100;

[0068] ②Canopy height: unit cm,...

Embodiment 2

[0131] The measurement of embodiment 2 test material index

[0132] This application randomly selected five materials of B0340 (Awn), A0504 ​​(Wujie), A0123 (Gi), A0118 (Nandi), D0302 (Qigang) from the Miscanth plant resource nursery of Hunan Agricultural University (see Table 2 for their sources) , to evaluate the adaptability potential of these five Miscanthus species. The evaluation results are shown in Table 3:

Embodiment 3

[0139] The verification of embodiment 3 evaluation results

[0140] Substituting the measured values ​​of the above examples into the calculation formula of theoretical energy yield in the existing literature, the result is basically consistent with the result of the evaluation method of the present invention. The difference is that the theoretical yield calculation formula in the literature is mainly related to the energy conversion rate, which belongs to the downstream stage of the industry; while the evaluation method of the present invention mainly involves aspects such as yield, quality and stress resistance, which belongs to the upstream stage of the industry.

[0141] The calculation formula of power generation is shown in formula 1, and the results are shown in table 4:

[0142] Power generation (kW·h·hm -2 ) = calorific value (MJ kg -1 )×10 6 (MJ·kg -1 Converted to KJ·t -1 )×0.35 (the efficiency of heat conversion into electricity process)×dry matter yield (t hm ...

Abstract

The invention relates to the biomass energy field, and especially relates to a Miscanthus spp. plant energy potential evaluating method comprising the following steps: selecting property indexes, and measuring Miscanthus spp. Plant property index data; obtaining property index scores; obtaining the energy potential index according to the property index scores. The research method can systematically breed the Miscanthus spp. energy plant; the method uses simple and direct agronomic, quality and stress resistance differences to build the Miscanthus spp. plant energy potential evaluating system; the system method is simple in operation, can only test the plants so as to fast determine germplasm energy potential and best utilization approach, thus laying basis for Miscanthus spp. energy plant breeding and large scale Miscanthus spp. plant germplasm energy potential evaluation work.

Description

technical field [0001] The invention relates to the field of biomass energy, in particular to an evaluation method for the suitable energy potential of Miscanthus plants. Background technique [0002] Miscanthus spp. refers to the perennial herbaceous plants of Gramineae, Panicoideae, Trib. . There are 14 species of Miscanthus in the world, and China has 7 species, which are the distribution center of Miscanthus, including 7 species of Miscanthus, Wujiemans, Di, Nandi, Nepalese, Shuangyao, and Red Mountain Mao . Miscanthus energy plants refer to Miscanthus plants with the characteristics of energy plants, which can be developed and utilized as energy crops, also known as "energy miscanthus". There are mainly 4 species of Miscanthus plants with potential energy in my country, including Miscanthus, Wujiemans, Di, and Nandi, while the energy plant of Miscanthus that has been popularized and utilized in Europe is Qigang, which is a diploid Miscanth and tetraploid. A triploid ...
