Problems solved by technology

[0002] As facility agriculture is a type of agriculture with strong human controllability, the current facility agriculture in the alpine region of Qinghai-Tibet is basically based on energy-saving solar greenhouses. The irrigation water for solar greenhouses in alpine regions is alkaline, which is likely to cause stem cracks, root calcification, and Infestation by diseases and insect pests, stunted growth, high equipment purchase and operation costs for industrialized water treatment methods, and high technical requirements for operators

Abstract

The invention discloses a treatment method of sunlight greenhouse irrigation water acidification in alpine region saline-alkali soil. A main fermentation device and solid-liquid separation device anda treatment technology of the sunlight greenhouse irrigation water acidification in the alpine region saline-alkali soil are included. The treatment technology comprises the eight steps of equipment installation, substrate preparation, solid fermentation regulation, solid-liquid mixing state fermentation regulation, acid adjustment treatment, solid liquid separation, irrigation regulation and slagtreatment. According to the method, low-cost acidification is conducted on alkali sunlight greenhouse irrigation water or sunlight greenhouse irrigation water with a higher Ph value in the alpine regions to allow the irrigation water to become weak acid or neutral irrigation water, concentration irrigation of the irrigation water is conducted on roots of crops through under-membrane irrigation, alkaline is buffered by an improved organic acid solution locally in alkali soil to promote the absorption of nutritious substances of crops, and physiological diseases and hazards of split stem and the like caused by calcareous condensation are reduced.

Description

technical field [0001] The invention relates to the technical field of soil improvement in saline-alkali land in alpine regions, in particular to an acidification treatment method for irrigation water in solar greenhouses in saline-alkali land in alpine regions. Background technique [0002] As facility agriculture is a type of agriculture with strong human controllability, the current facility agriculture in the alpine region of Qinghai-Tibet is basically based on energy-saving solar greenhouses. The irrigation water for solar greenhouses in alpine regions is slightly alkaline, which is likely to cause stem cracks, root calcification, and Infestation by diseases and insect pests, stunted growth, high equipment purchase and operation costs for industrialized water treatment methods, and high technical requirements for operators. [0003] Therefore, it is necessary to invent a method for acidifying the irrigation water of solar greenhouses in saline-alkali land in the alpine ...
