Disclosed is a nano-titanium and biological-sulfur-zinc-manganese mixture for melon powdery mildew. The nano-titanium and biological-sulfur-zinc-manganese mixture for melon powdery mildew is prepared from: a material 1 comprising 35% of 60-nm-ball polymerization titanium, 15% of sulfur powder, 20% of zinc sulfate, 25% of manganese sulfate, and 5% of chitin; and a material 2 comprising one part of monascus, one part of bacillus subtilis, one part of bacillus megatherium, one part of lactobacillus thermophilus, and one part of 25% brown sugar water. A preparing method of the nano-titanium and biological-sulfur-zinc-manganese mixture comprises: 1) adding the sulfur powder, the zinc sulfate, and the manganese sulfate into the 60-nm-ball polymerization titanium for dissolution, and placing the mixture in the sun for photodecomposition; 2) adding the microorganisms in the material 2 to the brown sugar water for enriching culturing for 3 d; and 3) putting the material obtained after the step 1 into a microorganism bucket obtained after enriching culturing in the step 2, adding the chitin for secondary fermentation for 7 d, and obtaining the nano-titanium and biological-sulfur-zinc-manganese mixture for the melon powdery mildew. The nano-titanium and biological-sulfur-zinc-manganese mixture is sprayed to the blade surfaces of melons, so that cell membranes of pathogens are broken, and 95% of the powdery mildew is effectively inhibited. |
