NOVELTY - Double-component composite microorganism water-retaining and temperature-controlling slow-release fertilizer comprises component A and component B', where weight ratio of component A to component B' is (1-5):(1-5); component A comprises 200-250 pts. wt. urea, 250-300 pts. wt. ammonium chloride, 80-120 pts. wt. ammonium dihydrogen phosphate, 60-100 pts. wt. potassium chloride, 80-120 pts. wt. water, 5-10 pts. wt. sodium alginate, 100-150 pts. wt. silicon dioxide; component B' comprises 30-50 pts. wt. furfural residue, 10-30 pts. wt. humic acid, 30-50 pts. wt. livestock manure, 20-40 pts. wt. plant ash, 20-40 pts. wt. cottonseed residue, 10-30 pts. wt. starch residue, 35-45 pts. wt. bentonite, 35-45 pts. wt. silicon dioxide, 45-55 pts. wt. temperature-control phase-change material, 10-30 pts. wt. earthworm, 1-10 pts. wt. Bacillus subtilisand 1-10 pts. wt. Bacillus licheniformis. USE - Double-component composite microorganism water-retaining and temperature-controlling slow-release fertilizer used for corn, sorghum, wheat, cotton, soybean, peanut, sunflower, fruit trees and vegetables (claimed). ADVANTAGE - The double-component composite microorganism water-retaining and temperature-controlling slow-release fertilizer has characteristics of complete nutrient elements, reasonable proportion, high efficiency, strong water retention and moisture retention, strong fertility, high yield, high quality, improve ecological environment of soil, optimize soil structure, environment-friendly and satisfy market demand. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) a method for preparing double-component composite microorganism water-retaining and temperature-controlling slow-release fertilizer, which involves: (a) adding sodium alginate into water, and uniformly mixing to obtain mixture a; (b) mixing uniformly urea, ammonium chloride, ammonium dihydrogen phosphate, potassium chloride and silicon dioxide, spraying mixture a, granulating and drying to obtain component A; (c) mixing earthworm, Bacillus subtilis and Bacillus licheniformis to obtain mixture b; (d) mixing furfural residue, humic acid, livestock manure, plant ash, cotton seed residue, starch residue, bentonite, silicon dioxide and temperature-control phase-change material uniformly at 25-30℃, adding mixture b, stirring and mixing uniformly, standing for 20-30 hours, and cooling to 10-20℃ to obtain component B'; and (e) adding component A into component B' at 10-20℃, stirring and uniformly mixing to obtain fertilizer; (2) a application of double-component composite microorganism water-retaining and temperature-controlling slow-release fertilizer, which is provided for corn, sorghum, wheat, cotton, soybean, peanut, sunflower, fruit trees and vegetables.
