Abstract

The present invention discloses application and an application method of special compound fertilizer for saline-alkali soil to acacia planting. The fertilizer is administered in saline-alkali soil for acacia planting. The special compound fertilizer comprises a microbial agent, a mineral fertilizer, an organic fertilizer, a slow release fertilizer and a controlled-release fertilizer by the mass ratio of 2:8:60:10:20. The fertilizer applied to acacia planting can effectively improve the transplant survival rate of acacia to 95.1%; and the fertilizer and acacia planting can improve saline-alkali soil structure, reduce salinity and pH value of the soil, increase soil fertility, and maintain lasting fertility, and is particularly conducive to improving the saline-alkali soil.

Description

Technical field [0001] The invention relates to the field of soil improvement of saline-alkali land, in particular to the application and application method of a compound fertilizer special for saline-alkali land in albizia plantation. Background technique [0002] Ecological restoration and improvement of saline soil is a project that benefits the country and the people. It can increase the area of ​​arable land, tap the agricultural potential, and is more conducive to the development of the agricultural industry. The improvement methods of saline-alkali soil generally adopt physical method, water conservancy method, chemical method, and biological method. Among them, the first three methods involve a lot of manpower and material resources, and the fourth method takes a long time and has slow results. [0003] However, the ecological restoration and improvement of saline-alkali soils with biological methods can solve the fundamental problem most, so there are more studies in this ...
