Fertilizer synergist, synergistic fertilizer and preparation method of synergistic fertilizer

Abstract

The invention discloses a fertilizer synergist. The fertilizer synergist contains malic acid, tartaric acid, citric acid, oxalic acid, succinic acid, humic acid and polyglutamic acid in a mass ratio of (0.01-0.12) to (0.01-0.12) to (0.10-0.26) to (0.10-0.27) to (0.10-0.22) to (0.01-0.1) to (0.01-0.1). The invention further discloses a synergistic fertilizer containing the fertilizer synergist and a preparation method of the synergistic fertilizer. The synergistic fertilizer has the following effects: (1) elements of nitrogen, phosphorus and potassium in soil can be activated, and the utilization rate of the fertilizer can be increased; (2) TCA cycle of plants is activated, and the energy supply is improved; (3) the absorption of elements of iron and magnesium is promoted, and the plant photosynthesis is enhanced; (4) the root heavy metals and the other abiotic stress are relieved; and (5) a soil microenvironment is improved, the soil activity is stimulated, and yields of food crops, leaf vegetables and melon-fruit commercial crops are effectively increased.

Description

technical field [0001] The invention relates to agricultural fertilizers, in particular to a fertilizer synergist, a synergistic fertilizer and a preparation method thereof. Background technique [0002] my country is a big country in the use of chemical fertilizers. The annual consumption of chemical fertilizers is as high as 50 million tons (converted to pure nitrogen, phosphorus and potassium), which has made outstanding contributions to agricultural development and grain production. However, the utilization rate of fertilizers is generally low. The seasonal utilization rate of nitrogen fertilizer is only 35%, that of phosphorus fertilizer is about 25%, and that of potassium fertilizer is about 50%. The loss of a large amount of fertilizer not only causes huge economic losses, but also causes serious environmental pollution. Therefore, in order to meet the requirements of the development of modern agriculture and overcome the bottleneck of resource and environment constr...
