Perennial flower dwarfing slow-release fertilizer

Abstract

The invention discloses a perennial flower dwarfing slow-release fertilizer. The perennial flower dwarfing slow-release fertilizer is prepared from the raw materials in parts by weight: 1.6-1.9 parts of a mepiquat chloride preparation, 7-8 parts of dipotassium phosphate, 3-4 parts of calcium lactate, 46-50 parts of rice bran, 13-15 parts of pod husk powder, 9-10 parts of turnip residue, 2-3 parts of polyaspartic acid, 35-36 parts of rice straw, 20-24 parts of fresh green tea leaf, 0.8-1.1 parts of ascorbic acid vitamin C, 1.2-1.4 parts of acetic anhydride, 0.2-0.3 part of 4-dimethylamino pyridine and a proper amount of water. The perennial flower dwarfing slow-release fertilizer provided by the invention can meet all kinds of nutrients needed during the growth of flowers; through coordinative addition of the mepiquat chloride preparation, the calcium lactate, the polyaspartic acid and the like, the perennial flower dwarfing slow-release fertilizer can inhibit the elongating growth of the flowers and promote the thickening growth of cells, so that effects that leaves are large, branches are strong, flowers are blooming and fruits are bright-colored are achieved, and the ornamental value of the flowers is improved.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a slow-release fertilizer for dwarfing perennial flowers. 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 environments such as Aci...

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
