An artificial soil structure for planting crops in unsuitable land such as Gobi desert or desert

Abstract

The invention discloses an artificial soil structure for planting crops in lands unsuitable for growth such as the Gobi Desert or deserts. The artificial soil structure is characterized in that a groove is formed, a clay layer (2) is laid on a desert stratum (1) at the bottom of the groove, a charcoal and clay mixed layer (3) is laid on the clay layer (2), a mixed layer (4) of charcoal, clay and organic matter is laid on the charcoal and clay mixed layer (3), a grave layer (5) is laid on the mixed layer (4) of the charcoal, the clay and the organic matter, and the thickness of the grave layer (5) is smaller than ten centimeters. Artificial soil of the artificial soil structure has the abilities of water preservation and fertilizer preservation and can continuously provide water and fertilizer for the crops, the clay at the bottom layer can prevent moisture from infiltrating and being lost, a soil mixed layer of the charcoal and the clay or mineral rich in clay has the functions of preventing nutrient and moisture from infiltrating, and the soil containing the charcoal and the clay or the mineral rich in clay and an organic matter layer are a main body for growth of the roots of the crops and are the main body for providing water and fertilizer for growth of the crops.

Description

technical field [0001] The invention relates to an artificial soil structure for planting crops, in particular to an artificial soil structure for planting crops in unsuitable lands such as Gobi Desert or desert. Background technique [0002] The arid areas in western China, especially the Xinjiang Autonomous Region, are important agricultural reclamation areas in my country, shouldering the important task of maintaining national unity, frontier stability and improving the living standards of people of all ethnic groups. The oasis agriculture characterized by irrigation is the economic basis of the arid area and plays a pivotal role in the social economy and national harmony. Since the founding of the People's Republic of China, the oasis land has been facing the pressure of cultivation brought by the increase of population. Recently, the country is going to carry out the development of the west, and the rapid population expansion has caused the demand for food and other ag...

Problems solved by technology

Recently, the country is going to carry out the development of the west, and the rapid population expansion has caused the demand for food and other agricultural products to cause more and more insufficient land resources suitable for living. As a result, the reclamation of saline-alkali land is increasing, and the reclamation of saline-alkali land requires a large amount of water resources. As a result, water resources that are already insufficient are becoming more and more scarce
