Method for improving adaptability of forestation plants in arid and semiarid areas

Abstract

The invention discloses a method for improving adaptability of forestation plants in arid and semiarid areas. The method includes the following steps of preparing the triazole plant growth regulator diluent according to the practical requirements in the plant growing season, and applying the diluent with the concentration ranging from 50 ppm to 3000 ppm to plants through leaf surface spraying or applying the diluent with the concentration ranging from 0.1 g a.i / m<2> to 5.0 g a.i / m<2> on plants through soil circulating application or furrow application. By means of the method, plants can be dwarfed, the spatial structure can be changed, and the vegetation coverage can be increased; stems and branches can be prevented from extending, the leaf area is remarkably reduced, and the leaf biomass is increased; the root system density and vigor are improved, the root shoot ratio is increased, the evapotranspiration loss on the aboveground part is reduced, the utilization efficiency of moisture is improved, moisture and temperature stress is reduced, adaptability of plants is enhanced, and therefore ground surface wind erosion is reduced, and the wind prevention and sand fixation effects are achieved; the method has the advantages of being large in application field number, wide in application range, high in benefit, small in residual hazard, small in dosage and the like.

Description

technical field [0001] The invention belongs to the field of desertification prevention and control of ecological construction, and relates to a method for improving the adaptability of afforestation plants in arid and semi-arid areas by using exogenous plant growth retardants, so as to achieve the purposes of increasing vegetation coverage in arid and semi-arid areas and preventing and controlling wind erosion. Background technique [0002] According to statistics, China's arid and semi-arid areas account for about half of the country's land area. Drought and lack of water resources are one of the most important factors restricting the economic, social development and ecological environment construction in these areas, and they are also the key factors affecting the development of the western region. Due to the impact of various natural factors (such as reduced rainfall, frequent droughts) and human factors (such as population increase, unreasonable development, etc.), some...

Problems solved by technology

[0004] The above research content is mainly to achieve the purpose of vegetation restoration by improving the soil moisture conditions for vegetation growth. Both the initial investment and the later management require more manpower and material resources; Variety, long cycle, and large investment, all of which are not compatible with the poor human and financial resources in arid and semi-arid areas
