Fertilizer for inhibiting potato soil-borne diseases and preparation method thereof

Abstract

The invention discloses a fertilizer for inhibiting potato soil-borne diseases and a preparation method thereof. The fertilizer is prepared from the following raw materials in parts by weight: 45-65 parts of kitchen wastes, 20-30 parts of biogas slurry, 32-44 parts of corncobs, 10-15 parts of mature rice vinegar, 15-25 parts of wheat bran, 14-22 parts of pepper meal, 12-18 parts of citric acid residues, 10-15 parts of castor cakes, 8-14 parts of crab shell powder, 5-10 parts of sasangua cake powder, 16-24 parts of coco peats, 10-15 parts of quicklime, 4-6 parts of maple leaves, 2.5-4.5 parts of garden balsam flowers, 3-5 parts of curly dock roots, 2-4 parts of pharbitis seeds, 4.5-6.5 parts of stems of anthelmintic ironweed, 3-6 parts of cucumber stems, 22-34 parts of urea, 18-26 parts of potassium dihydrogen phosphate, 15-20 parts of ammonium sulfate, 5-10 parts of potassium chloride, 1-2 parts of zinc sulfate and 20-30 parts of composite stone particles. The fertilizer disclosed by the invention not only contains nutrient elements necessary for the growth of potatoes but also contains an active ingredient for killing or inhibiting soil-borne pathogens, so that the fertilizer can improve the disease resistance of the potatoes, reduce the incidence rate of the potato soil-borne diseases, promote the healthy and rapid growth of the potatoes, and improve the yield and the quality of the potatoes.

Description

technical field [0001] The invention relates to a fertilizer for suppressing potato soil-borne diseases and a preparation method thereof, belonging to the field of agricultural fertilizers. Background technique [0002] Potatoes are Solanaceae Solanum, annual herbaceous plants, also known as ground eggs, yams, potatoes, etc., are important crops for grain, vegetables, and feed. The ingredients in fresh potatoes: starch 9-20%, protein 1.5-2.3%, Fat 0.1-1.1%, crude fiber 0.6-0.8%. The protein, fat, sugar, crude fiber and various vitamins it contains are indispensable to the human body. With the continuous awareness of the nutritional value of potatoes and the continuous expansion of market demand, more and more attention has been paid to the production of potatoes. Potatoes are prone to soil-borne diseases during the production process. At present, most of the fertilizers used for potatoes in the market do not have the function of inhibiting soil-borne pathogens, or the abil...
