Method for transforming pure poplar forest in arid region into poplar and acacia mixed forest

By cutting down Xinjiang poplar trees in alternating rows and intercropping them with young black locust trees in pure Xinjiang poplar forests in arid areas, combined with planting ditches and tending management, the problem of growth decline in pure Xinjiang poplar forests in arid areas was solved, and stable and efficient mixed forest transformation and degraded forest stand restoration were achieved.

AI Technical Summary

⚠Technical Problem

Due to long-term wind erosion and high-temperature drought conditions, the growth of pure poplar forests in arid areas has declined, resulting in a large number of low-quality, low-efficiency degraded stands. Existing methods for replanting poplar trees in Xinjiang have not been very effective.

⚗Method used

By cutting down Xinjiang poplar in alternate rows, cultivating black locust saplings and intercropping them in deeply dug planting trenches, combined with targeted tending management, a mixed forest of Xinjiang poplar and black locust is formed. The drought resistance of black locust and the nitrogen fixation by rhizobia are used to improve soil fertility and promote the stable growth of the mixed forest.

🎯Benefits of technology

It has improved the ecological benefits of poplar forests in arid Xinjiang, reduced soil erosion, increased biodiversity, stabilized forest structure, and enhanced the windbreak and sand-fixing function of forest land.

Abstract

The present application relates to the technical field of forest cultivation, in particular to a method for transforming pure Xinjiang poplar forest in arid area into Xinjiang poplar and pagoda tree mixed forest. The method comprises the following steps: cutting in the row of the Xinjiang poplar forest with a canopy density greater than 0.7, digging a planting ditch on the vacant land after cutting, and planting the pagoda tree seedlings cultivated in the seedling bag for one year in advance in the planting ditch in the form of row mixed planting, then cutting off the remaining Xinjiang poplar in the forest when the diameter at breast height of the pagoda tree seedlings reaches 3cm-4cm, reserving a Xinjiang poplar sprout, and performing conventional tending management until a stable Xinjiang poplar and pagoda tree mixed forest is formed. The method combines row thinning, staggered cutting and afforestation, utilizes the mutual promotion relationship between trees, adopts afforestation and tending and pruning measures in different time periods, and efficiently transforms the degraded pure Xinjiang poplar forest into mixed forest of different ages through a gradual method, so that the protective forest in arid area can continuously play ecological benefits, reduce soil erosion, increase biodiversity and stabilize the forest stand.
