Problems solved by technology

The problem here is: the preparation method of hydroxywollastonite mentioned in the materials is mainly based on hydrothermal synthesis. The disadvantage is that the particle size of the hydroxyapatite after synthesis is too small, so it is difficult to be used in fertilizers. The role of a carrier, and the preparation process is complicated, it is difficult to be directly applied to the adsorption and application of organic matter and the production of fertilizers

Embodiment 1

[0020] An organic fertilizer for improving the sticky and water-retaining properties of sandy soil, characterized in that it is made of the following raw materials in parts by weight (Kg): zeolite 25, 2mol / L Na 2 HPO 4 Solution 45, calcium chloride 12, camphor leaves 12, culture pond sludge 18, cassava residue 50, banana peel 22, corn cob 40, colloid bacillus bacterial agent 2, poultry feather 20, 5mol / L dilute sulfuric acid solution 45, Bean curd residue 25, rice bran 6, fish meal 10 and appropriate amount of water.

[0021] A method for preparing an organic fertilizer for improving the adhesive water-retaining properties of sandy soil, characterized in that it comprises the following steps:

[0022] (1) Calcinate the zeolite at a high temperature for 10-15 minutes, then grind the sand through a 10-20 mesh sieve, and put 2mol / LNa 2 HPO 4 In the solution, absorb for 45~60min at the vibration frequency of ultrasonic frequency 45~55W, and filter out the zeolite sand;

Abstract

The invention discloses an organic fertilizer for improving soil gluing water retention property of sandy ground and a preparation method thereof; the organic fertilizer is prepared from, by weight, zeolite, 2 mol / L Na2HPO4 solution, calcium chloride, cinnamomun camphcra leaf, sludge in culture pond, manioc waste, banana peel, cob, colloid bacillus fungicide, poultry feather, 5 mol / L dilute sulphuric acid solution, tofukasu, rice bran, fish meal and proper amount of water. According to the invention, the feather taking amino acid as the main component can be better degraded in later maturity stage; meanwhile, colloid bacillus is added to ferment together, thus the fermented maturity material has more gum contents, the stickiness is strong; water absorbing and fertilizer remaining ability are good; the organic fertilizer is very suitable for the planting environment with gravel mostly such as tea trees in hilly area.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to an organic fertilizer for improving the sticky and water-retaining properties of sandy soil and a preparation method thereof. Background technique [0002] Hydroxyapatite (Ca 10 (PO 4 ) 6 (OH) 2 ) has good adsorption to metal ions and biomacromolecules. In recent years, people have done a lot of research on its adsorption properties, and hydroxyapatite column is considered to be one of the most effective technologies for the separation and purification of biomacromolecules one. The adsorption of hydroxyapatite (HAP) to short-chain organics, polymers, salivary proteins, catamycin, lysozyme, and proteins has been studied. HAP and inorganic ions (such as Ca 2+ and F - ) was achieved by ion exchange and surface adsorption. However, the interaction between HAP and organic matter is mainly through surface adsorption. M. Kresak believes that HAP adsorbs low-mole...
