Abstract

A medium trace element long-acting compound fertilizer capable of improving soil and suitable for black earth comprises, by weight, 15-25 parts of organic fertilizer, 8-15 parts of potash fertilizer,7-15 parts of phosphate fertilizer, 4-6 parts of medium trace elements, 10-30 parts of humic acid activated through an ammoniation method, 4-6 parts of macromolecular organic protein water-retaining agent, 0.2-0.5 part of composite microbial flora and 0.6-0.9 part of coating nutrition agent. The composite microbial flora is a mixture of Fungi IMperficti, Trichoderma Viride and Bilaiae Penicilliumin the weight ratio of 4:3:3. The compound fertilizer solves the antagonism problem of elements in the fertilizer, so that organic substances of the black earth are increased, stable yield and yield increase of crops are guaranteed, and the soil of the black earth can be improved.

Description

technical field [0001] The invention relates to a medium and trace element long-acting compound fertilizer with soil improvement effect and suitable for black soil. Background technique [0002] The increasing use of chemical fertilizers year after year, the adjustment of "high-yield" crop structure, and the threat of wind and sand erosion have caused the organic matter content of black soil soil to drop by up to 70%, and the thickness of the black soil layer has been reduced by nearly half. The degradation of black soil is serious. The nutrient capacity of the land itself is reduced, and it has to be supplied by external nutrients. The natural output of black soil is not as high as it was in the 1960s and 1970s. [0003] Most of the black soil reclaimed fields are grasslands, with an organic matter content of about 8% to 10%, and now only about 3%. The main reason is the reclamation of farmland, predatory management, and unbalanced use and cultivation. Cultivation turns ...
