Abstract

The invention discloses an acid soil conditioner prepared from red algal waste and kitchen waste. The acid soil conditioner is prepared by mixing red algal waste powder, solid waste of food residue, waste fungus sticks, dolomite powder and shell powder according to a weight ratio of 1:0.8:0.8:0.1:0.1, wherein the red algal residue powder is supplied from red algal waste, and the solid waste of food residue is supplied from the kitchen waste. The acidic soil conditioner has the advantages that the pH (potential of hydrogen) value of the soil is obviously increased, and the acidity of the soil is improved; after applying, the content of alkaline-decomposing nitrogen, content of quick-effect potassium and content of effective phosphor in the soil are certainly increased, and the acid soil conditioner is suitable for the improvement of tobacco-planting soil.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to an acidic soil conditioner prepared by using red algae waste residue and kitchen waste. Background technique [0002] Soil is an important medium for plant growth. To ensure the rapid development of my country's growing population, urban and rural construction, and the sustainable development of my country's agriculture, it is necessary to meet the crop's requirements for soil fertility and ensure soil quality. In the south of my country, the temperature is high and rainy, the soil leaching of calcium, magnesium and other basic ions is serious, and the soil is generally acidic; in addition, most farmers still rely on chemical fertilizers to increase crop yields, and excessive use of acidic chemical fertilizers, with the multiple cropping index and The increase of production years has made the soil acidification in the southern region more and more obvious. Therefo...
