Abstract

The invention discloses a paddy fertilizer for efficiently improving acid paddy soil. The formula of the medicament contains nano carbon powder, oil shale, weathered coal, limestone, zeolite, vermiculite, red mud, ardealite, potassium polyacrylate, potassium humate, bacillus laterosporus, azotobacter vinelandii, aspergillus oryzae, streptomyces jingyangensis, chitin and calcium magnesium phosphatefertilizer in certain proportion. The paddy fertilizer can improve acid paddy soil, so as to increase the soil pH value, improve the soil structure stability, reduce dissolution of heavy metal of thesoil, increase the content of nutritive elements in soil, play a promotion role for paddy growth and yield increase, and lay a foundation for wide improvement of acid paddy soil in the south, thus having wide application prospect.

Description

technical field [0001] The invention relates to the field of agricultural science and technology, in particular to a rice fertilizer for efficiently improving acidic paddy soil. 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 av...
