A method for storing water, storing water, and enriching grass at the bottom of the grassland without disturbing the soil layer at intervals

Abstract

A kind of grassland interval and not disturbed soil layer bottom tillage water storage and abundant grass method, is to utilize the bottom tillage fertilization device to carry out interval cutting loose soil below 15-20 centimeters apart from the grassland soil layer surface, between the loose soil area and the loose soil area The interval is 60-80 cm, and the width of the loose soil area is 50-60 cm; the width of the laceration on the surface of the grassland in the loose soil area is controlled below 15 cm. Underground oxygen storage; apply fertilizer into the soil loosening area while loosening the soil. In this method, the degraded grassland is cultivated at intervals and strips of local undisturbed soil layers, and the undisturbed soil layer cultivation area is intersected with the original ecological grassland area, so as not to damage the grassland vegetation and not affect the dust on the ground to cause sand and dust disasters. Under certain conditions, local bottom loosening can be achieved, grassland soil reservoirs can be established, soil nutrients can be activated, grassland vegetation growth can be promoted, and new grassland growth and ecology can be created.

Description

technical field [0001] The invention relates to the technical field of grassland management, in particular to a method for bottom plowing, storing water, storing water and enriching grass at intervals in the grassland without disturbing the soil layer. Background technique [0002] It is understood that my country's grassland area is 43.2 billion hectares, accounting for 13% of the world's grassland area, second only to Australia, and is the second largest grassland country in the world. my country's grassland resources mainly include grasslands in the north, grassy hills and slopes in the south, coastal tidal flats, wetlands, and natural grasslands in agricultural areas, such as the famous Ili Nalati grassland in Xinjiang, the Xilin Gol grassland in Inner Mongolia, the Hulunbeier grassland in Inner Mongolia, and the Xilinhot grassland in Inner Mongolia. The sky is blue, the wild is vast, and the wind blows the grass and sees the cattle and sheep.” It can be seen that the gra...

Problems solved by technology

Artificial fertilization has become a commonly used grassland improvement measure. However, excessive fertilization will cause soil compaction, which is effective for pasture growth in the short term, but it is not good for long-term excessive use.
