Embodiment 1

[0015] After 3 years of interplanting Cassia rotifera in the orchard, the total soil organic carbon (0-20cm) increased by 37.25% compared with the control (soil without interplanting Cassia), and the total amount of humic acid and fulvic acid also increased by 153.78% respectively. % and 6.76% (as shown in Table 1).

[0017]

Embodiment 2

[0019] After 10 years of clear tillage and interplanting of Cassia rotifera in orchards, the soil organic carbon density increased by 10.7% and 34.5% respectively. The annual change of soil carbon is 3.2 times that of the clear tillage model. The soil carbon sequestration rate of interplanting Cassia rotifera in orchard is 714.52kgC·hm -2 ·a -1 (As shown in table 2).

[0022] Example 2

[0023] Interplanting Cassia rotifera in red soil orchards can better improve the soil and comprehensively improve soil physical and chemical properties (see Table 3). After planting Cassia rotifera for 3 years, various physical and chemical properties of the soil have been greatly improved, especially the organic carbon content An increase of 74%; the annual increase rate of soil organic carbon fixation is 15.59%, which is significantly higher than other invented techno...

Abstract

The invention discloses leguminous forage for improving carbon fixation of an orchard garden, belongs to the technical field of carbon fixation and emission reduction of an agriculture ecosystem, and solves the problem of higher emission of carbon dioxide of the orchard garden in the prior art. The leguminous forage with high lignin content is screened and intercropped in the orchard garden, wherein the high lignin content is of between 17 and 24.6 percent; the leguminous forage is sown for a plurality of years for use; and the carbon dioxide is adsorbed through the growth and the photosynthesis of the leguminous forage and is converted into organic carbon and soil organic matters so as to improve the absorption and the fixation of an ecosystem of the orchard garden and realize the effects of the carbon fixation and the emission reduction of the agriculture ecosystem.

Description

technical field [0001] The invention belongs to the technical field of carbon fixation and emission reduction in agricultural ecosystems, and in particular relates to interplanting of leguminous herbage for improving the carbon absorption and fixation of orchard ecosystems. Background technique [0002] Carbon sequestration refers to the capture, separation, storage or reuse of carbon dioxide. Atmospheric CO 2 The volume fraction has changed from 285 x 10 in 1850 -6 Up to 365×10 in 1996 -6 . Atmospheric CO 2 There are 3 main anthropogenic factors for the volume fraction increase: fossil fuel combustion, cement production, and land use and tillage changes. Among them, land use and tillage change are important aspects of human influence on the carbon process of terrestrial ecosystems. In most cases, the conversion of natural land to cultivated land will lead to a rapid decline in soil organic carbon (SOC). Scholars from all over the world have conducted a large number o...
