Soil conditioner prepared from biogas residues and furfural residues

Abstract

The invention relates to a soil conditioner. The soil conditioner is prepared from, by weight, 100 parts of biogas residues, 40 parts of furfural residues, 100 parts of straw and a proper quantity of a water-retaining agent. A preparation method is provided for acidified soil, soil fertility is enhanced, soil where the soil conditioner is applied enables acidophilous plants such as ericaceae and orchidaceae and other plants to grow well, and garden diversification development is promoted.

Description

technical field [0001] The invention belongs to the technical field of soil improvement, and in particular relates to a preparation method of a soil improver. Background technique [0002] The soil in the north of my country is mostly neutral and slightly alkaline soil. Many plants grown in the south and north, such as rhododendrons, camellias, cycads, orchids, gardenias, etc., are acid-loving soil flowers. The usual methods of acidifying the soil, such as adding sulfur, are likely to cause soil compaction. [0003] On the other hand, in my country, the annual discharge of furfural slag is large, and the amount of pollution caused by stacking is large, which urgently needs to be rationally utilized as a resource. Furfural slag is a kind of biomass waste, in which the organic matter content is 40%, the nitrogen, phosphorus, and potassium contents are 3.4%, 2.8%, and 1.9% respectively, and the pH value is about 2. It is a highly efficient organic acidic fertilizer. [0004]...
