This invention belongs to the field of Amomum villosum cultivation technology, specifically relating to an intensive cultivation method for improving pollination efficiency and yield of Amomum villosum under forest cover. The method includes the following steps: In the early flowering stage of Amomum villosum, 15-20 plants are grouped into a unit, and a fixing strap is used to wrap around and bind the plants 1-1.6m above the base of the plant, forming a cluster unit. After physical clustering, the planting area is cleared, exposing the ground surface to more than 60% of the cluster unit area. Appropriate gaps are left between adjacent cluster units to improve ventilation within the group and provide pathways for pollinating insects to fly and visit flowers. An induction solution containing 1-2 ml / L nonanal is sprayed onto the root and stem area of ​​the cluster unit. This invention, through a series of operations including physical stress, shifts the focus from vegetative growth to reproductive growth, significantly increasing the natural flowering rate and pollination efficiency, thereby substantially increasing yield.

This invention provides a novel structure for economic land use under forest cover, comprising, from bottom to top, a native soil layer, a mesh layer, a water-conducting grid layer, a sand cushion layer, and a solidified soil layer. The mesh layer covers the native soil layer, and the water-conducting grid layer covers the mesh layer. The mesh layer includes an HDPE three-dimensional honeycomb grid with a height of 10±5mm. The sand cushion layer, composed of medium-coarse sand and / or gravel, is filled within the HDPE three-dimensional honeycomb grid. The solidified soil layer covers the sand cushion layer. This entire structural system ensures natural water infiltration and circulation, meets ecological protection requirements, and avoids the damage to forest ecological functions caused by traditional hard paving. The solidification method used efficiently utilizes the in-situ soil under the forest cover, reducing the need for purchased materials and waste soil, thus lowering construction costs and ecological disturbance. The crystals produced by the solidifying agent are embedded in the native soil under the forest cover, acting as a framework and making the native soil more stable.

This invention belongs to the field of plant cultivation technology, specifically a method for simulating wild cultivation of Polygonatum sibiricum under forest cover. The method includes the following steps: S1, cultivating edible fungi under the forest canopy. After harvesting the fungi, the remaining mycelial network and organic matter are used to form a fungal residue layer, naturally improving the forest soil. The forest soil is then divided into multiple equidistantly distributed semi-buried modular simulated wild cultivation troughs. This method for simulating wild cultivation of Polygonatum sibiricum under forest cover, by setting up semi-buried modular simulated wild cultivation troughs and employing a multi-layered soil structure consisting of a biomimetic surface cover layer, a planting substrate layer, a moisture-retaining buffer layer, a drainage layer, and an isolation layer, constructs a highly simulated forest micro-ecological environment, achieving natural soil improvement and sustainable utilization, and effectively enhancing the quality and medicinal components of Polygonatum sibiricum.

This invention provides a high-yield method for cultivating *Agaricus bisporus* under forest cover in northern China, relating to the field of edible fungi cultivation technology. The method includes the following specific steps: Step 1: Preparation of the planting substrate. By weight percentage, select 50% whole threshed corn cobs, 15% rice husks, 10% broadleaf tree sawdust, and 25% pre-fermented cow and sheep manure, and prepare the materials for later use. Step 2: Substrate pre-fermentation treatment. In northern regions, pre-fermentation begins in early April. Cow and sheep manure is piled up for pre-fermentation one month in advance. When the pile temperature reaches 60℃, it is turned over, and a total of three turns are performed to complete the pre-fermentation. This invention provides a high-yield method for cultivating *Agaricus bisporus* under forest cover in northern China, making full use of local agricultural and forestry waste and idle forest resources. Through optimized substrate formulation, standardized fermentation control, and a dual-cycle fruiting mode adapted to the northern climate, it achieves high-yield, high-quality, and long-cycle cultivation of *Agaricus bisporus*.

By establishing a complete technical chain from data acquisition, feature extraction, semantic optimization to prevention and control decision-making, it realizes the transformation of Fritillaria cirrhosa growth status from passive discovery to active early warning, and from experience judgment to quantitative assessment, improving the accuracy of early disease identification and spatial positioning precision.

This invention provides an effective planting method to alleviate the continuous cropping obstacles of Gastrodia elata, relating to the field of agricultural planting technology. The invention involves first pre-treating the soil with a composite substrate, and then applying microbial inoculants during planting. This ensures the normal growth of Gastrodia elata under forest cover in a semi-wild environment, inhibits the harm caused by continuous cropping obstacles, reduces the occurrence of Gastrodia elata diseases, and guarantees the yield and quality of Gastrodia elata. Generally, after planting Gastrodia elata, the land needs to be left fallow for four to five years before it can be planted again on the same plot. Using the method of this invention, the yield of Gastrodia elata planted on land that has been fallow for one year can be increased by 181.42% to 236.28%, while the yield is only reduced by 14.41% to 28.37% compared to the first planting. This invention can effectively alleviate the problem of limited forest land resources caused by continuous cropping obstacles of Gastrodia elata and promote the large-scale development of the semi-wild cultivation industry of Gastrodia elata under forest cover.
