Coated fertilizer for woody flowers and plants

Abstract

The invention discloses a coated fertilizer for woody flowers and plants. The coated fertilizer is prepared from the following raw materials in parts by weight: 43 to 47 parts of soybean curb residues, 12 to 15 parts of eggshells, 7 to 8 parts of water hyacinth powder, 6 to 8 parts of ammonium dihydrogen phosphate, 2 to 3 parts of calcium carbonate, 2 to 3 parts of calcium lignosulphonate, 1.2 to 1.6 parts of crustacean amine, 37 to 43 parts of young orange and tangelo fruit, 1.2 to 1.4 parts of dimethylformamide, 2.5 to 2.6 parts of jasmonic acid methyl ester, 0.8 to 1.0 part of polyving akohol, a suitable amount of 50% ethanol solution, a suitable amount of 70% methanol solution, and a suitable amount of water. The coated fertilizer disclosed by the invention is applicable to the woody flowers and plants; on the basis of supplementing conventional fertilizer nutrients to the flowers and plants, the solidness of stem fibres of the flowers and plants is enhanced, the development of xylems of the flowers is reinforced and powerful support is provided for picking, grafting and the like of the woody flowers and plants by adding the calcium lignosulphonate, the crustacean amine and the like which are in a plant absorbable state; the ornamental value of the woody flowers and plants is also improved by the characteristic of strengthening branches and toughening stems of the coated fertilizer; the coated fertilizer has a very good using effect.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a woody flower-coated fertilizer. Background technique [0002] With the development of specialization, industrialization and scale of planting in our country, its requirements for fertilizers are constantly upgrading, while traditional fertilizers have restricted the sustainable development of planting industry due to their low nutrient utilization. The application of coated fertilizer is an effective way to solve this problem. However, at present, the coating materials of common coated fertilizers are mainly chemically synthesized non-degradable polymers, which are easily left in the soil and cause soil degradation and pollution. At the same time, the coating materials have a single function and usually only have slow and controlled release. The effect does not take into account the functions of water absorption, antibacterial, anti-oxidation and the practicability for dif...

Problems solved by technology

[0004] The special fertilizer formula for flowers provided by CN101913953B includes photosynthetic bacteria, chitosan, synergist, trace element mixture, nitrogen, phosphorus and potassium inorganic nutrients and natural plant essence, but its nitrogen source, phosphorus source, and potassium source do not have slow-release effects , and are still dominated by large amounts of elements such as nitrogen, phosphorus, and potassium, which cannot well meet the needs of flowers for medium and trace elements, and need to be supplemented separately, which increases the cost of fertilization. adjust accordingly
