Organic fertilizer for preventing and controlling root-knot nematodes and preparation method of organic fertilizer

Abstract

The invention discloses an organic fertilizer for preventing and controlling root-knot nematodes and a preparation method of the organic fertilizer. The organic fertilizer comprises the following raw materials by weight parts: 30-35 parts of bovine urine, 23-28 parts of peanut cake powder, 4-5 parts of a seaweed extract, 2-3 parts of salicylic acid, 5-7 parts of sodium hexametaphosphate, 2-3 parts of potassium iodate, 18-20 parts of shell powder, 1-2 parts of sodium bicarbonate, 1.0-1.2 parts of sodium chloride, 4-6 parts of calcium phenylpropionate, 10-12 parts of calcium carbonate, 3-4 parts of lanthanum oxide, 2-4 parts of sodium citrate, 1.5-1.7 parts of sodium dodecyl benzene sulfonate, 20-22 parts of a soil fertility enhancer, 0.7-0.9 part of dimethyl sulfoxide, 0.3-0.5 part of compound amino acid, 5-7 parts of hawthorn powder, 10-12 parts of pumpkin flesh, 7-9 parts of alligator alternanthera and 13-15 parts of luffa stems. The organic fertilizer has the effects of promoting growth, improving soil, improving the quality of agricultural products and preventing and controlling the root-knot nematodes of various plants; the killing rate of second-instar larvae is more than 80%; a chemical preparation is not added, so that the soil and crops are pollution-free, residue-free and non-drug-resistant; the raw materials are rich, the production cost is low, and the process is simple.

Description

technical field [0001] The invention relates to an organic fertilizer for preventing and controlling root-knot nematodes and a preparation method thereof, belonging to the technical field of fertilizer manufacturing. Background technique [0002] The harm of root-knot nematodes to plants is characterized by the formation of clusters of spherical root nodules of different sizes on the main root and lateral roots of the plant. After the plant is parasitized, the root system becomes shorter, the root hairs of the lateral roots become less, and the transporting tissue is destroyed and deformed. The dredging tissue is destroyed, water and nutrients cannot be transported to the plant, resulting in weak growth of the ground part, short plants, abnormal leaf color, few fruits, low yield, and even death of the plant, and the root-knot nematode will carry more infections. A variety of pathogenic fungi and bacteria; the current prevention methods for root-knot nematodes mainly includ...

[0002] The harm of root-knot nematodes to plants is characterized by the formation of clusters of spherical root nodules of different sizes on the main root and lateral roots of the plant. After the plant is parasitized, the root system becomes shorter, the root hairs of the lateral roots become less, and the transporting tissue is destroyed and deformed. The dredging tissue is destroyed, water and nutrients cannot be transported to the plant, resulting in weak growth of the ground part, short plants, abnormal leaf color, few fruits, low yield, and even death of the plant, and the root-knot nematode will carry more infections. A variety of pathogenic fungi and bacteria; the current prevention methods for root-knot nematodes mainly include physical methods such as crop rotation and temperature suppression; chemical agents; microorganisms; soil electric disinfection, etc. These methods have their own advantages and disadvantages, and physical methods cannot Thoroughly remove root-knot nematodes, chemical agents are prone to produce resistance to root-knot nematodes, and there will be residues after use, which is easy to pollute the soil. The soil electric disinfection method is inconvenient to operate and the price is high
