This invention discloses a soil regulation method and its application for promoting high and stable yields in peak-producing chestnut stands. It belongs to the field of forestry cultivation and soil management technology. This invention addresses the problems of soil compaction, nutrient imbalance, and degradation of biological functions caused by traditional extensive management practices. It innovatively implements synergistic and precise regulation from three dimensions: soil physical properties, chemical properties, and beneficial fungal communities. This includes: controlling the porosity and water holding capacity of specific soil layers within an optimized range through measures such as covering with organic materials; adjusting the content of key soil nutrients, organic matter, and pH to suitable ranges; and constructing a microbial community containing seven specific types of beneficial fungi with sufficient abundance, inoculated according to a specific time sequence. This method solves the long-standing technical problem of lacking precise management standards, increasing chestnut yield by 1.13–9.74 times, with an annual yield variation coefficient remaining stable at 2.66%, achieving a significant and stable yield increase. Furthermore, it is simple to operate and easy to promote.

The utility model relates to undergrowth planting technology supporting device technical field, especially a kind of Chinese chestnut falling collection device;Including: first elastic binding rope, is equipped with multiple equidistantly arranged knots;Second elastic binding rope, is equipped with multiple equidistantly arranged knots;Limiting sleeve, the upper portion of the first elastic binding rope knot is inserted, the lower portion of limiting sleeve knot is inserted in the second elastic binding rope;L-shaped connecting strip, including splicing section and collection net connecting section, the splicing section of L-shaped connecting strip is detachably inserted in the inner hole of limiting sleeve;Collection net body, detachably connected to the collection net connecting section of L-shaped connecting strip by connecting piece;In connected state, first elastic binding rope is tied in Chinese chestnut tree trunk, second elastic binding rope is tied in Chinese chestnut tree trunk, the collection net connecting section of L-shaped connecting strip is radially unfolded, and collection net body forms horn shape with opening upward, the above improvement can facilitate the automatic collection of Chinese chestnut when undergrowth planting baihaocha.
