Problems solved by technology

[0003] The most important means of prevention and control in traditional agriculture is to use pesticides and soil for disinfection, but it causes a large amount of pesticide residues and causes environmental pollution
In the prior art, there are also some bio-organic fertilizers that are used to prevent and treat vegetable root-knot nematodes. Although they have a certain control effect, the control effect is still not ideal.

Abstract

The invention discloses a bio-organic fertilizer for preventing and treating vegetable root knot nematode disease and a preparation method thereof. The bio-organic fertilizer for preventing and treating vegetable root knot nematode disease comprises a product obtained by mixing and fermenting tobacco straw fermentation products and distillers' grains. The preparation method of the bio-organic fertilizer for preventing and treating the vegetable root knot nematode disease comprises the following steps: (1) weighing the tobacco straw fermentation product, the rape cake, the vinasse, the total nutrients of nitrogen, phosphorus and potassium and the medium trace elements in parts by weight; (2) uniformly mixing the tobacco straw fermented product, the oilseed rape cake and the vinasse, spraying a fermentation inoculant, and carrying out stacking fermentation at normal temperature; and (3) after the fermentation in the step (2) is finished, mixing total nutrients of nitrogen, phosphorus and potassium and medium trace elements, uniformly mixing, granulating and packaging. The organic fertilizer has a relatively strong function of preventing and treating vegetable root-knot nematode diseases, not only can prevent infection of root-knot nematodes, but also can kill the infected root-knot nematodes so that the root-knot nematodes are more comprehensively prevented and treated.

Description

technical field [0001] The invention relates to the field of bio-organic fertilizers, in particular to a bio-organic fertilizer for preventing and treating vegetable root-knot nematode and a preparation method thereof. Background technique [0002] Root-knot nematode is one of the important root diseases that seriously affects the yield of vegetable cultivation in the world. It has the characteristics of wide distribution, multi-host, strong infectivity and hidden damage, especially in Solanaceae, Cucurbitaceae and other plants. more common. It mainly harms the roots of various vegetables, and forms tumors after infection, which affects the absorption of water and nutrients by the plants. The aerial parts of the affected plants grow short and slow, with abnormal leaf color, few fruits, deformed fruits, low yield, and premature plant death. [0003] The most important means of prevention and control in traditional agriculture is to use pesticides and soil for disinfection, b...
