Abstract

The invention discloses nutrition-balanced slow-release fertilizer for lotus roots. The nutrition-balanced slow-release fertilizer is prepared from the following raw materials in parts by weight: 43 to 55 parts of urea, 23 to 40 parts of ammonium dihydrogen phosphate, 12 to 20 parts of kiln ash potassium fertilizer, 4 to 12 parts of precipitated phosphorus fertilizer, 0.1 to 0.3 part of calcium sulfate, 1 to 3 parts of borax, 0.2 to 0.4 part of manganese humate, 0.1 to 0.2 part of iron humate, 40 to 50 parts of organic fertilizer, 0.1 to 0.14 part of saccharomycetes agent, 0.03 to 0.1 part ofbacillus subtilis agent, 0.01 to 0.05 part of aspergillus niger agent and 4 to 10 parts of slow releasing agent. The organic fertilizer is prepared from the following components in parts by weight: 10to 16 parts of maize cob meal, 12 to 24 parts of fermented sesame meal, 5 to 12 parts of rice bran and 9 to 14 parts of fertilized land radishes. The slow releasing agent is prepared from the following components in parts by weight: 1 to 4 parts of modified slow releasing agent, 1 to 3 parts of zeolite powder and 2 to 4 parts of weathered coal.

Description

technical field [0001] The invention relates to the technical field of lotus root planting, in particular to a nutritionally balanced slow-release fertilizer for lotus root. Background technique [0002] The lotus root is sweet and sour, and has many nutritional values. It can regulate blood pressure in both directions. It has a certain effect on maintaining cardiovascular function and preventing diseases such as vascular sclerosis and hypertension. In addition to eating fresh, lotus root can also be processed into dietary health products. Drinking lotus root juice can produce body fluid and quench thirst, and has high nutritional value. At present, lotus root has been using the traditional mode of multiple application of chemical fertilizers, and insufficient attention has been paid to the balance and slow release of nutrient elements, which is an important reason for the poor development of lotus root. Contents of the invention [0003] Based on the technical problems e...
