Problems solved by technology

[0004] The object of the present invention is to provide a method for fertilizing barren soil in newly reclaimed sloping land in the Ili River Valley. The method aims at the problem that the slope of the newly reclaimed sloping land in the Ili River Valley is large, thin, barren, and prone to soil erosion and aggravates the loss of soil nutrients. After harvesting winter wheat, leave stubble for no-tillage and interplant corn and soybeans directly along the contour line. Combined with optimizing the water and fertilizer management of wheat, corn, and soybeans, while reducing the blank

Abstract

The invention relates to a fertilizing method for improving fertility of poor soil of a new reclamation slope of Ili river valley. The method aims to settle the problems of large gradient, small soil thickness, low fertility, and soil nutrient loss caused by easy soil erosion in the new reclamation slope of Ili river valley. Through performing stubble mulch non-tillage and directly interplanting of corns and soybeans along an isoline after winter wheat is harvested, and optimizing water and fertilizer control management on the wheat, corn and soybean, culturing blank period shortening and soil erosion reduction are realized. Furthermore soil fertility is improved through soil conservation by leguminous plants and straw returning of autumn crops, thereby realizing maturation of the poor soil at the new reclamation slope, keeping surface coverage of the new reclamation slope and reducing soil erosion in the culturing blank period. Furthermore through optimized water and fertilizer management measures, poor soil maturation through fertilizing and water-and-soil conservation of the poor soil at the new reclamation slope of Ili river valley are realized.

Description

technical field [0001] The invention relates to a method for cultivating soil fertility of newly reclaimed land in arid areas, in particular to a new method for cultivating soil fertility of barren soil in newly reclaimed slopes in valleys in arid regions. Background technique [0002] More than 40% of the world's continental area is covered by arid and semi-arid areas, and the arid area in Northwest my country is more than a quarter of the country's land area. The dry and rainless climate, weak soil development and sparse vegetation cover have created a fragile and easily disturbed ecological environment in the arid area. Due to the limited suitable water and soil natural resource conditions and the unique oasis economic development model in the arid area, more than 90% of the agricultural and population settlements are concentrated around the surface water system, the edge of the piedmont alluvial fan, and the river valley in the arid area. With the increase of population...
