A Method of Improving Barren Land

Abstract

The invention discloses a barren land improvement method. Land improvement is conducted through land reclamation devices, and the land reclamation devices comprise a ploughing device, a pulverizing device, a soil taking device and a soil stirring-blowing device which are connected through land. The barren land improvement method comprises the following steps that ploughing is conducted, wherein deep ploughing is conducted on the land through the ploughing device; 2, straw or crop straw or putrid plant shrubs or livestock manure is pulverized through the pulverizing device; 3, soil and pulverized materials obtained in the step 2 are together placed in the soil stirring-blowing device through the soil taking device, and stirring is conducted; 4, the soil mixture obtained after stirring is placed on the land through the soil taking device; 5, the soil mixture is wetted by adding water and covered with film, the soil added with the water is fermented, and the soil humidity is kept to be 60%-80%. According to the barren land improvement method, no pollution is generated to the environment, the cost is low, the effects are rapidly achieved, the land environment is fundamentally improved, and the land fertility is improved.

Description

technical field [0001] The invention relates to a method for improving land, in particular to a method for improving barren land. Background technique [0002] Land barrenness is also called land degradation. The lack of nutrients in the land, the destruction of the land structure, the erosion of the land, the thinning of the soil layer, the compaction of the land, the acidification, alkalization, and desertification of the land, and the obvious decline in land fertility are all important manifestations of land barrenness. , this kind of land is not easy to cultivate, the suitable cultivation period is short, and the cultivation quality is poor. In the 21st century, my country has entered a critical period of accelerating the transformation of traditional agriculture and taking the path of agricultural modernization with Chinese characteristics. Modern science is used to find effective technologies to improve the micro-ecological environment of the land, improve land fertili...
