Special fertilizer for cut side slope soil remediation in high altitude areas

Abstract

The present invention provides a special fertilizer for cut side slope soil remediation in high altitude areas, which is prepared by effectively compounding raw material components of a yak manure-containing compost, an organic micro multi-element fertilizer, a chemical fertilizer, attapulgite powder and sodium alginate under certain conditions. The special fertilizer has obvious effects on the aspects of improving the physicochemical properties of artificial soil at cut side slope wounds in the high altitude areas, increasing the fertilizer efficiency and promoting vegetation restoration.

Claims

2. The fertilizer for cut side slope soil remediation in high altitude areas according to claim 1, wherein the chemical fertilizer is prepared from various effective elements in percentage by weight (by pure nutrients): 5-25% of nitrogen, 3-21% of phosphorus pentoxide and 5-21% of potassium oxide.

3. The fertilizer for cut side slope soil remediation in high altitude areas according to claim 1, wherein the various elements in the chemical fertilizer are provided by the following substances respectively: nitrogen from urea and ammonium phosphate and ammonium sulfate, phosphorus from calcium superphosphate and diammonium phosphate and diammonium phosphate and potassium from potassium chloride and potassium sulfate and potassium dihydrogen phosphate.

4. A fertilizer for cut side slope soil remediation in high altitude areas, comprising the following components: a sample 1, a sample 2, a chemical fertilizer, attapulgite powder and sodium alginate, wherein the sample 1 contains the following components: yak manure, sheep manure, vinasse, sawdust and chitin oligosaccharides; and the sample 2 contains one or more of tartaric acid, lysine, valonia extract and diglycolamine, one or more of water and hydrogen peroxide, borax, zinc sulfate, ferrous sulfate, copper sulfate and manganese sulfate.

5. The fertilizer for cut side slope soil remediation in high altitude areas according to claim 1, wherein the various elements in the chemical fertilizer are provided by the following substances respectively: nitrogen from urea or ammonium phosphate or ammonium sulfate, phosphorus from calcium superphosphate or diammonium phosphate or diammonium phosphate and potassium from potassium chloride or potassium sulfate or potassium dihydrogen phosphate.

Description

DETAILED DESCRIPTION OF PREFERRED EXAMPLES

(1) The present invention is further described below in combination with the examples.

Example 1

(2) The yak manure and the vinasse were uniformly mixed according to the weight ratio of 50 to 50, and then aerobic composting was performed on a mixture to obtain a yak manure-containing compost for later use; the tartaric acid with the weight percent of 25% was put into a reaction kettle and was dissolved with the water with the weight percent of 25%; then the following components in percentage by weight were added into the reaction kettle: 15% of the borax, 15% of the zinc sulfate, 10% of the ferrous sulfate, 5% of the copper sulfate and 5% of the manganese sulfate; the complicated reaction was performed for 2 hours at 100 C.; pressurization of 3 kg/cm.sup.2 was performed after cooling is performed to room temperature; and the components were stood for 20 hours, and then cured and dried to prepare an organic micro multi-element fertilizer for later use; and the following components in percentage by weight were compounded: 20% of the yak manure-containing compost, 10% of the organic micro multi-element fertilizer, 25% of the ammonium sulfate, 18% of the ammonium phosphate, 25% of the potassium sulfate, 1% of the attapulgite powder and 1% of the sodium alginate, to prepare a final product.
