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.

First claim

We claim:

1 . A special fertilizer for cut side slope soil remediation in high altitude areas, prepared by the following steps:
(a) uniformly mixing yak manure, sheep manure, vinasse, sawdust, and chitin oligosaccharides with a weight ratio of (35-70) to (0-50) to (5-50) to (0-25) to (0-35), and then performing aerobic composting on a mixture to obtain a sample 1; (b) putting at least one of tartaric acid, lysine, valonia extract and diglycolamine with the weight percent of 10-35% into a reaction kettle; dissolving the component with at least one of the water and the hydrogen peroxide with the weight percent of 10-35%; then adding the following components in percentage by weight into the reaction kettle: 10-40% of borax, 15-50% of zinc sulfate, 10-40% of ferrous sulfate, 5-35% of copper sulfate and 5-35% of manganese sulfate; performing a complicated reaction for 0.5-6 hours at 70-130° C.; pressurizing by 2-6 kg/cm 2 after performing cooling to room temperature; and standing for 10-50 hours, and curing and drying to obtain a sample 2; and (c) mixing the following components in percentage by weight: 5-30% of the sample 1, 5-20% of the sample 2, 55-85% of the chemical fertilizer, 0.5-5% of the attapulgite powder and 0.5-5% of the sodium alginate to prepare a final product.

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

4 . A special 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.
