Composite water-retaining coated fertilizer for flowers and plants

Abstract

The invention discloses a composite water-retaining coated fertilizer for flowers and plants. The composite water-retaining coated fertilizer is prepared from the following raw materials in parts by weight: 3.4-3.6 parts of cyclodextrin, 36-38 parts of manioc waste, 24-26 parts of dregs of tea-oil tree fruit, 12-14 parts of chestnut shell powder, 7-9 parts of calcium nitrate, 3-4 parts of ammonium sulfate, 2-4 parts of lentinan, 2-3 parts of xanthan gum, 43-46 parts of tangelo fruitlet, 1.0-1.2 parts of dimethyl formamide, 2.4-2.8 parts of jasmonic acid methyl ester, 0.9-1.1 parts of polyving alcohol, a proper amount of a 50% ethanol solution, a proper amount of a 70% methanol solution and a proper amount of water. Since organic matters are used as additives of the coated fertilizer disclosed by the invention, structural improvement of a flower cultivation medium is achieved, and the surface tension of the medium is improved; due to addition of cyclodextrin, xanthan gum and the like, the fertilizer is relativelygood in water absorption property; compared with a common high-molecular compound water-retaining agent, the composite water-retaining coated fertilizer has the advantages of high degradation speed and low cost and is applicable to flower planting in drought regions.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a composite water-retaining coated fertilizer for flowers. 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 t...

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
