Microbial fertilizer applicable to improvement of flaky salinized areas in Ningxia and Inner Mongolia in China

Abstract

The invention relates to a microbial fertilizer applicable to improvement of flaky salinized areas in Ningxia and Inner Mongolia in China. The microbial fertilizer comprises 1 to 1.5 of rice husk, 10to 15 of humic acid, 10 to 16 of balloonflower roots, 30 to 40 of earthworm soil, 2 to 3 of cytokinin, 1 to 3 of gibberellins, 15 to 20 of peroxyacetic acid, 8 of Sulfolobus acidocaldarius, 6 of Bacillus megaterium, 4 of nitrogen fixation bacteria and 2 of ferment bacteria. Directed at the characteristic of soil in flaky salinized areas in Ningxia and Inner Mongolia in China, the rice husk and theballoonflower roots are cooperated with humic acid to improve soil nutrients; the earthworm soil absorbs oozed low-position steam and fully immobilizes the steam on the surface of a soil layer; gibberellin and peroxyacetic acid rapidly fracture one-piece alkalized soil and isolated fractured alkalized soil; and then a great amount of communicating fermentation broth of Sulfolobus acidocaldarius and Bacillus megaterium obtained after glycolysis infiltrates into alkaline soil with biological components, and rapid differentiation and proliferation are realized among blocks, so the leaching and desalination capabilities of soil are improved, and the content of accumulated salt in each alkaline earth block is continuously reduced.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a microbial fertilizer suitable for improvement in Ningmeng sheet-shaped saline areas. Background technique [0002] Soil characteristics of the flaky saline areas in Ningxia and Inner Mongolia: Ningmeng flaky saline areas are located on plateaus with arid climate, sparse vegetation, groundwater level declines year after year, leaching and desalination processes are weak, and the low groundwater level leads to the lack of nutrients in the soil. It causes widespread salt accumulation in the land, forming a large area of ​​salinization, and it is not conducive to irrigation, which brings great difficulties to the planting industry. The advantage of microbial fertilizer is that it can form a dominant population around the root system of plants through the massive reproduction of beneficial bacteria, which inhibits the life activities of other harmful bacteria. It can quickly de...
