Embodiment 1

[0022] 1. Experimental materials and methods

[0023] (1) Pre-cultivation conditions of Paronymus diangi

[0024] Wash and weigh 40 annual Prunus diangi, transplant them into seedling bags, and pre-cultivate them in a culture room for 10 days under normal atmospheric carbon dioxide concentration (400ppm). The light intensity is 300 μmol m -2 the s -1 , 12 hours of light per day, the cultivation temperature is 18-23°C, and the air humidity is 60%.

[0025] (2) Experimental culture conditions

[0026] After pre-cultivation for 10 days, 20 of them were placed in CO 2 Concentration of 800ppm in the cultivation room, the remaining 20 plants of Polyaceae were left in CO 2 Concentration of 400ppm (CK) culture room, start to do a comparative test. In addition to CO 2 Except for the different concentrations, the other environmental culture conditions of the two culture chambers are the same. The light intensity is 300 μmol m -2 the s -1 , 12 hours of light per day, the cultiv...

Abstract

The invention provides a method for accelerating biomass accumulation of paris polyphylla by increasing the carbon dioxide concentration. The method comprises the steps of increasing the carbon dioxide concentration in the environment, accumulating the biomass of paris polyphylla, pre-culturing paris polyphylla, and achieving carbon dioxide concentration treatment and culture. The invention relates to the technical field of bioengineering. The method is a novel means for promoting quick biomass accumulation of paris polyphylla by increasing the carbon dioxide (CO2) concentration. Increase of the carbon dioxide concentration in the environment accelerates accumulation of fresh weight of paris polyphylla seedlings. The method has a production promotion function in actual production. By changing and increasing the content of main carbon sources required by the paris polyphylla in the environment, the requirement of actual production for yield increase of the paris polyphylla is met, and the cultivation and planting efficiency of the paris polyphylla is further improved.

Description

Technical field: [0001] The invention belongs to the technical field of bioengineering, and specifically relates to a synthesis method for promoting biomass by carbon dioxide, and more specifically, a method for accelerating biomass accumulation of Parisia diaphylla when the concentration of carbon dioxide increases. Background technique: [0002] carbon dioxide (CO 2 ) is the main source of organic matter formation in plants and participates in important biochemical functions in plants. CO in the general atmosphere 2 The concentration is 350-400ppm. As the main carbon source for plants, CO 2 The biomass accumulation of plants accelerates when the concentration of α increases. It has been mentioned in many articles that the whole plant biomass and each organ biomass of perennial plants have a significant effect on CO 2 concentration response. De Souza et al. found that at high CO 2 After concentration treatment, the total biomass, leaf biomass, stem biomass and plant ...
