Fertilizer mixture for increasing yield and color of sweet potatoes

Abstract

The invention discloses a fertilizer mixture for increasing the yield and the color of sweet potatoes. The fertilizer mixture is prepared from, by weight, 10-20 parts of phosphate compounds, 6-8 partsof willow barks, 10-15 parts of urea solution, 10-15 parts of bacillus subtilis culture substances, 10-20 parts of rice husks, 20-30 parts of guar bean gum, 6-10 parts of photosynthetic bacteria, 50-60 parts of plant stems and leaves, 6-8 parts of trichoderma strains, 3-5 parts of Guanyin powder, 10-20 parts of diammonium hydrogen phosphate, 0.2 -4 parts of cellulose, 10-15 parts of dried pine needles and 0.2-0.6 part of xylo-oligosaccharide. The fertilizer mixture has the advantages that a fertilizer is sufficient in nutrient, directional matching is implemented according to requirements ofthe sweet potatoes, and the sweetness and the color of the sweet potatoes are guaranteed.
