Abstract

The invention discloses an acid paddy soil modifier. The composition of the modifier is prepared from biomass black charcoal, dolomite, sepiolite, limestone, zeolite, vermiculite, bentonite, coal ash,polyacrylamide, arbuscular mycorrhizal fungus inoculant, pig manure fermented substrates and super absorbent resin according to a certain proportion. By means of the acid paddy soil modifier, acid paddy soil can be modified, the soil pH value is increased, the soil structural stability is improved, dissolution of heavy metals in the soil is reduced, the contents of nutrient elements in the soil are improved, the modifier plays a part in promoting growth and yield improvement of paddies, a foundation is laid for widely modifying the south acid paddy soil, and thus the modifier has wide application prospects.

Description

technical field [0001] The invention relates to the field of agricultural science and technology, in particular to an acidic paddy soil improver. Background technique [0002] Soil acidification refers to the acceptance of H input into the soil + After, on the one hand H + Exchange reaction with the basic cations on the soil colloid to be adsorbed on the surface of the soil particles, and the exchanged basic cations are then leached away with the seepage water; on the other hand, the H+ on the surface of the soil particles will spontaneously and The aluminum on the surface of the mineral lattice reacts and is rapidly converted to exchangeable aluminum. Because soil acidification is an important aspect in the process of soil weathering and soil formation, it will lead to a decrease in soil pH value. After the formation of acidic soil, it will affect the activity of organisms in the soil, change the form of nutrients in the soil, reduce the availability of nutrients, and pro...
