The invention discloses a rhododendron lapponicum seedling culture medium and a preparation method thereof, and relates to the technical field of ornamental plant culture. The rhododendron lapponicum seedling culture medium is prepared from the following raw material components in parts by mass: 30 to 40 parts of masson pine needle compost, 25 to 35 parts of camellia oleifera shell ferment, 10 to 15 parts of perlite, 8 to 12 parts of vermiculite, 5 to 10 parts of peat soil, 0.3 to 0.8 part of folium cortex eucommiae extract, 0.2 to 0.6 part of honeysuckle vine extract, 0.5 to 1.0 part of humic acid and 0.3 to 0.7 part of calcium superphosphate. According to the method, agricultural and forestry waste source organic materials and inorganic conditioning materials are reasonably proportioned, plant extracts with biological activity are introduced, a seedling raising system which is synergistically optimized in the aspects of a physical structure, a chemical environment and biological functions is constructed, the growth vigor of seedlings is remarkably improved, and the yield of the seedlings is increased. A new technical scheme is provided for green, efficient and sustainable industrial seedling culture of the alpine rhododendron.

This invention discloses a management method for improving the carbon sequestration capacity of Masson pine forests, belonging to the field of Masson pine forest management technology. The method includes steps such as land preparation and clearing, density optimization, mixed planting, formation of multi-layered forests, and post-management. Through the above method, pure Masson pine forests are transformed and managed into multi-layered mixed forests. During this process, fermented fertilizer prepared from pine needle litter is applied to increase the organic matter content of the forest soil, promote good tree growth, increase biomass, and optimize forest stand structure. This, in turn, enhances the carbon sequestration capacity of the tree layer, understory vegetation layer, and soil layer, comprehensively improving the carbon sink capacity of Masson pine forests, which is of great significance for improving the ecological environment.

Provided are robotic systems and methods for identifying a particular type of tree or plant (e.g., slash pine trees), for tapping them and collect their oleoresin for processing using an autonomous, long-range robotic forest rover. One aspect of the system comprises an autonomous vehicle equipped with an industrial robot, automated tool changer, a plurality of tools required for robotic operations, vision and navigation systems and powertrain for long-range operation. The rover identifies healthy, mature trees or plants, approaches them and performs the robotic operations required for tapping the trees or plants. In addition to these tasks, the Global Navigation Satellite System (GNSS) coordinates of the tree or plant is recorded along with its diameter, and a digital image of the tree or plant. This information is communicated to a base station for creating and updating a tree farm database.

The invention relates to the technical field of plant detection, in particular to application of a PmACAA1 gene in determination of masson pine seed vigor. The activity of the pinus massoniana seeds is judged by testing the relative expression quantity of the PmACAA1 gene, and if the expression quantity of acetyl coenzyme A acyltransferase is reduced, the activity of the pinus massoniana seeds is high. By means of the PmACAA1 gene, the activity of the pinus massoniana seeds can be efficiently and rapidly judged, and the method is not limited by the germination period of the seeds. According to the method provided by the invention, the efficiency of testing the activity of the pinus massoniana seeds is greatly improved, a good early-stage tool is provided for storage, later-stage cultivation and the like of the pinus massoniana seeds, and the economic benefit and the social benefit are good.

The invention discloses a method for interplanting phoebe zhennan in a pure masson pine forest to cultivate a mixed forest, and belongs to the technical field of masson pine forest management. Large-size phoebe zhennan container seedlings are cultivated and transplanted, a root cluster dispersing agent is prepared and applied during transplanting, the dispersing agent can effectively disperse root clusters and promote root systems to extend into soil, and therefore the soil quality is improved; the method solves the problem that the growth condition is reduced due to limited nutrient and moisture absorption after transplanting caused by root system winding and seedling raising container obstruction of large-sized nanmu container seedlings, ensures the survival rate and good growth condition of the large-sized nanmu container seedlings cultivated in the masson pine forest, and can effectively improve the management benefit of the masson pine forest. The method disclosed by the invention has a good application prospect in operation and transformation of the pure masson pine forest.

The invention belongs to the field of forestry carbon neutralization, and discloses a carbon emission accounting and carbon footprint evaluation method in a masson pine operation process. According to the method, based on a full life cycle dynamic evaluation principle of a masson pine operation process and product production, the masson pine operation and product production process is divided into two sub-stages: a forestation stage and a product production stage; the method comprises the following steps: tracking production activity input and output of process units in each stage, constructing a life cycle list, constructing a carbon footprint accounting model of masson pine operation and product production processes by using an emission factor method according to different activities and carbon emission types, and meanwhile, carrying out uncertainty and sensitivity analysis to realize scientific carbon footprint accounting. The technical gap of carbon footprint accounting of the whole life cycle of the timber forest product is filled, the transparency and accuracy of the whole industry chain accounting of the forestry product are improved, the process low-carbon regulation and production technology improvement are facilitated, the cost is further reduced, the supply chain is comprehensively optimized, and the overall carbon footprint is reduced.

The invention discloses a method and system for estimating the total carbon reserve of a target ecological system carbon library, and relates to the technical field of forestry information, and the method comprises the following steps: carrying out the sample collection of a target ecological system; the vegetation type of the target ecological system is a subtropical evergreen broad-leaved forest, cypress, masson pine, alder and quercus acutissima are taken as main materials, the altitude is 182-954 m, the gradient is 0-45 degrees, the soil is yellow soil and purple soil, and the thickness of a dry branch and fallen leaf layer is 0-15 cm; the sample comprises at least one of a soil sample, a vegetation sample and a litter layer sample; carrying out analysis and calculation on the basis of the sample to obtain the total carbon reserve and carbon density of the target ecological system; the total carbon reserves and carbon density distribution characteristics of the target ecological system comprise the carbon density of a vegetation layer, the carbon reserves of the vegetation layer, the carbon density of a soil layer, the carbon reserves of the soil layer, the carbon density of a litter layer and the carbon reserves of the litter layer.
