Method for planting macadamia tree in rocky desertification soil

Abstract

The invention discloses a method for planting macadamia tree in rocky desertification soil. The method is that concave pits in rock, naturally formed in a rocky desertification region are expanded to form grooves not less than 80*80*60cm; gaps in the grooves are filled with mixed clay; 20 to 30cm mixed clay is paved at the bottom parts of the grooves to form a planting layer; macadamia grafting seedlings are subjected to field planting in the grooves; semicircular water stopping grooves are built in the lower sides of the grooves in the downward direction of the slope of the rocky desertification soil, so that the grooves form a water storing mechanism; water storing grooves are formed close to the grooves; at least one of the ends of the water stopping grooves extends to water inlets of the water storing grooves, and thus excessive water in the grooves can be guided into the water storing grooves; the mixed clay is prepared by mixing the following components in parts by weight: 30 to 50 parts of bottom mud of a fish pond, 50 to 80 parts of humic acid soil, 10 to 20 parts of fly ash, and 10 to 15 parts of attapulgite clay.

Description

technical field [0001] The invention relates to the field of rocky desertification soil treatment, in particular to a method for treating rocky desertification soil by planting macadamia fruit trees on the rocky desertification soil. Background technique [0002] Rocky desertification is the abbreviation of "rocky desertification". It refers to the destruction of surface vegetation caused by human activities under the tropical and subtropical humid and semi-humid climate conditions and the natural background of karst development, resulting in serious loss of soil and bedrock. The phenomenon of land degradation with large areas of bare or gravel accumulation is also an extreme form of land degradation in karst areas. For a long time, the natural vegetation in Guangzhou, Yunnan and other areas of my country has been continuously destroyed, and large areas of steep slopes have been opened up, resulting in exposed ground. In addition, the soil layer in karst rocky mountainous ar...

Problems solved by technology

The climatic conditions in some areas of Yunnan and Guangzhou in my country are more suitable for the planting of macadamia fruit trees. At present, macadamia fruit trees have been planted in botanical gardens or farms in Yunnan, my country. Therefore, there is no research and report on the planting of macadamia fruit trees on rocky desertification soil.
