Description
Technical Field
The invention belongs to the technical field of agriculture, and particularly relates to an aluminum-silicon material for tree planting and a tree planting method.
Background
At present, the silica fume is mainly treated in a centralized stacking mode except a small amount of silica fume used as a ceramic raw material, the aluminum fume is mainly treated in a centralized stacking mode, and the silica fume and the aluminum fume both occupy the land and have the problem of dust pollution. In addition, in northwest China, a large amount of sandy land and grassland exist, and the surface soil layer structure of the land mainly comprises a sandy soil layer as upper surface soil, a calcareous soil layer (namely calcareous soil layer soil) with the depth of about 1 meter below the sandy soil layer, and a clay layer below the calcareous soil layer. The roots of the grass and the trees are difficult to penetrate through the calcareous layer soil of the soil layer structure, and in addition, the northern rainwater is less, and the irrigation condition is poor, so that the landscape with the grass and without the trees is formed, and the current situation that the trees planted on the sand land are difficult to survive and grow is formed. The planting technology accumulated from ancient times has the defects that the tree roots cannot penetrate through the calcareous layer soil, so that the trees are difficult to survive and cannot be planted economically and practically. If a tree planting method using aluminum ash and silica ash as tree planting materials aiming at the soil layer structure can be invented, the root system of the tree can penetrate through the calcareous soil layer under the sand or the grassland and reach the clay layer, the tree seedling grows for several years after surviving in the same year, the root system of the tree penetrates through the calcareous soil layer and enters the clay layer, the root can absorb the moisture of the clay layer, the clay layer can be gradually cured, and the nutrition is further provided for the root, so the growth condition of the tree is greatly improved. If the planting life is 30-100 years, the fast-growing tree species (such as hybrid Chinese holly, fast-growing poplar, elm and Chinese scholar tree) can be planted in the forest after several years. If the trees are used for sand prevention and fixation, the defects of short service life (only 7 years) of the salix mongolica planted by sand prevention and fixation and complicated 'stumping and rejuvenation' management and operation can be overcome, a foundation can be laid for woodland formation and grassland planting diversification of a desert land, and the ecological civilization and sustainable development significance is realized.
