Problems solved by technology

[0003] In the north, most of the poplar forests are used to transform the saline-alkali land, but the species is too single, which makes the contradiction with the ecological environment increasingly prominent: poplar pests and diseases are rampant, poplar catkins pollute the environment, and the soil is barren, etc.

Embodiment

[0014] In the first ten days of February 2016, in Fushan Town, Ningyang County, Tai'an City, Shandong Province, the transformation of poplar artificial simple forest was carried out. The forest is 3 years old. The transformation steps are as follows:

[0015] Determine 100 mu of poplar artificial simple forests that need to be transformed, and the ratio of black locust and poplar in the mixed forest is 18:1, carry out poplar thinning according to the method of intermixing between plants with rows, replant the seedlings of black locust in the same year, pay attention to the management and protection in the later stage, and ensure Survival rate of locust saplings.

[0016] Preferably, the method of intermixing among rows of plants is as follows: that is, 34 rows of black locusts are used as one belt, and then one row of poplars is planted, and two strains of black locusts are mixed between the poplars.

[0017] Preferably, in the method for constructing a black locust mixed fore...

Abstract

The invention relates to a construction method of a Robinia pseudoacacia mixed forest with desalting and soil-modifying functions. The construction method includes specific steps of determining an artificial Populus forest to be reformed, and a ratio of Robinia pseudoacacia to Populus of the mixed forest being 18:1 to 20:1; intermediately felling Populus trees by means of band-row mixing of singletrees; filling with one-year plantlets of Robinia pseudoacacia; paying attention to late management, so that survival rate of Robinia pseudoacacia plantlets is guaranteed. The construction method provided herein has the advantages that the cultivation steps are simple and reasonable, the construction method is easy to master, the trees of Robinia pseudoacacia and Populus are loosely scattered, forest growth is evidently promoted, biomass quantity is increased, desalting and soil-modifying effects are evident for saline-alkaline soil, and the construction method has certain popularization andapplication value.

Description

technical field [0001] The invention relates to the technical field of afforestation of mixed forests, in particular to a method for building a black locust mixed forest with the function of reducing salt and improving soil. Background technique [0002] A mixed forest is a forest made up of two or more tree species. Mixed forests can form multi-level or thick canopy stand structures, which play an important role in improving protection efficiency and stability. In recent years, mixed forests have been widely used in soil and water conservation, water conservation, mine restoration, and desertification treatment. [0003] In the north, most of the poplar forests are used to transform the saline-alkali land, but the species is too single, which makes the contradiction with the ecological environment increasingly prominent: poplar pests and diseases are rampant, poplar catkins pollute the environment, and the soil is barren, etc. The current large-scale simple poplar plantat...
