Perennial flower slow-release fertilizer for extending flowering phase

Abstract

The invention discloses a perennial flower slow-release fertilizer for extending flowering phase. The perennial flower slow-release fertilizer is made from the following raw materials by weight: 45-48 parts of castor cake, 15-18 parts of fresh green tea, 0.5-0.6 part of ascorbic acid vitamin C, 23-25 parts of water hyacinth powder, 9-10 parts of oil cake, 5-6 parts of sodium selenite, 10-11 parts of humic acid ammonium, 2-4 parts of dextrin, 35-37 parts of rice straw, 0.9-1.1 parts of acetic anhydride, 0.2-0.3 part of 4-dimethylamino pyridine and a proper amount of water. The slow-release fertilizer has comprehensive nutrients; fermented organic matter, sodium selenite and dextrin are subjected to extraction complexation to significantly improve the degree of nutrients utilization of flowers; the strong anti-oxidation of theanine extract further enhances the stability of the cell membrane of the flower cell membrane, improve color and moisture of pedals, prolong the flowering phase, and provide good technical basis for flower ornamentation in tourist attractions and city horticultural flower planting.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a slow-release fertilizer for perennial flowers that prolongs the flowering period. Background technique [0002] With the increasing level of modernization of agriculture, coated slow-release fertilizers are widely used because of their remarkable high fertilizer efficiency. However, most of the slow-release fertilizers currently on the market are facing many problems. First, a large amount of greenhouse gases are likely to be generated during the preparation process, and are discharged into the atmosphere without control, causing air pollution; second, the coating materials are chemically synthesized. These non-degradable high-molecular polymers, these refractory polymer coating materials are very easy to remain in agricultural soil, causing soil degradation and serious pollution; third, fertilizers are bulky and inconvenient to transport and store; fourth, for special soil...

However, most of the slow-release fertilizers currently on the market are facing many problems. First, a large amount of greenhouse gases are likely to be generated during the preparation process, and are discharged into the atmosphere without control, causing air pollution; second, the coating materials are chemically synthesized. These non-degradable high-molecular polymers, these refractory polymer coating materials are very easy to remain in agricultural soil, causing soil degradation and serious pollution; third, fertilizers are bulky and inconvenient to transport and store; fourth, for special soil environments such as Acid-base, drought-humidity, soil lacking some elements, and nutrient requirements of specific crops are not effectively targeted
