Problems solved by technology

However, due to the inability to accurately select the best harvesting period, people currently harvest biogas-specific energy plants to judge only by common experience, so that the maximum production capacity per unit land area cannot be fully utilized, and the maximum economic benefits of perennial biogas-specific energy plants cannot be obtained.

Embodiment Construction

[0016] The specific implementation method of the present invention will be further described below by taking the perennial energy plant Jujuncao as an example. The present invention includes but is not limited to the following examples.

[0017] A method for determining the optimal harvest period of perennial biogas-specific energy plants comprises the following steps:

[0018] (1) One year after the planting of Jujuncao, use the present invention to determine its best harvest period.

[0019] (2) Select 12 subsections of 10 square meters in the Giant Juncao planting area, and harvest the Giant Juncao in the entire planting area in March. Harvest a partitioned energy plant every 30 days from that day on.

[0020] (3) Measure the total fresh weight of the plants produced in the entire partition of the giant Juncao harvested in step (2), then take out a part to measure the fresh weight, crush them, dry them to measure their dry weight, calculate the total solid content of the p...

Abstract

The invention discloses a method for determining the optimum picking time of perennial energy plants special for marsh gas, and belongs to the field of biomass energy. By means of the method for harvesting perennial energy plants in a segmented mode, through the combination of the measurement of the dry matter yield and the analysis of the independent marsh gas fermentation effect, the optimum picking time of the perennial energy plants special for marsh gas is determined. The method is easy and convenient to operate and credible in result and has quite high actual production and popularization value.

Description

technical field [0001] The invention belongs to the field of biomass energy and relates to the harvesting of biogas energy plants, in particular to a method for determining the optimum harvest period of perennial biogas energy plants. Background technique [0002] With the depletion of fossil fuels such as petroleum, coal, and natural gas, the development and utilization of renewable energy, especially biomass energy, has been paid more and more attention by countries all over the world. Biogas is an important renewable energy, which has flexible and changeable practical application value and a good industrialization foundation, and has gradually attracted people's attention. [0003] There have been a lot of researches on the production of biogas by anaerobic fermentation of energy plants, such as a method of producing biogas from huangzhucao (200910029204.7), a method of preparing biogas from fermentation of Spartina alterniflora (200610116145.3), giant juncao Planting an...
