Preparation and application methods of plant healthcare agent special for treating root nematodes

Abstract

The invention provides a plant healthcare agent special for treating root nematodes, and preparation and application methods of the plant healthcare agent. The plant healthcare agent special for treating the root nematodes comprises EM bacteria, verticillium chlamydosporium, potassium fulvate, rooting powder, chitosan oligosaccharide and trace elements. The components are reasonable, the root nematodes can be effectively prevented, and the nutrition is rich. Nutrition ingredients necessary to plant growth can be provided, the resistance of a plant can be improved, the disease resistance of the plant can be effectively improved, and the quality of the plant is improved. The preparation method of the plant healthcare agent special for treating the root nematodes is simple and practicable, high in production efficiency, low in application cost, simple in operation, easy to implement, stable in quality of a product, convenient to apply, good in adaptability, and high in popularization and application value.

Description

technical field [0001] The invention belongs to the field of agricultural science and technology, and in particular relates to a plant health-care agent for treating root nematodes, and a preparation and application method of the plant health-care agent for root nematodes. Background technique [0002] Root nematodes mainly damage the roots. Root-knot nematodes mainly invade the roots of plants with second-instar larvae, causing root nodules to form on the roots, especially lateral roots and fibrous roots. In severe cases, large amorphous tumors are formed on the upper part of the root knots. Uneven, and the roots gradually rot, and the plants die due to lack of water. Among them, after being infected, the symptoms of the aboveground parts of plants with mild disease are not obvious, and the aboveground parts of severe cases have obvious abnormal changes, and the affected plants are stunted and grow slowly. In severe cases, the plants will wilt as if they lack water. At f...

Problems solved by technology

At present, chemical control is still the most important control measure for plant parasitic root nematode diseases, but chemical nematicides have many problems such as high toxicity, high residue, high cost, easy pollution of the environment, and poor environmental compatibility.
