Root-knot nematode control carbon-based medical fertilizer and preparation method thereof

Abstract

The invention discloses a root-knot nematode control carbon-based medical fertilizer and a preparation method thereof. The carbon-based medical fertilizer comprises lythidathion, abamectin B2, wood vinegar, biomass charcoal, carrier fertilizers and adhesives. By applying the carbon-based medical fertilizer, soil diseases such as root-knot nematodes and bacterial wilt can be persistently and effectively controlled, the use ratio of the carrier fertilizers is increased, the physicochemical property of soil can be regulated, soil hardening is prevented, double pest control effects of fertilizer application and pesticide application can be simultaneously achieved by applying the medical fertilizer once, the disease resistance effect of vegetables can be remarkably enhanced, vegetable quality is improved, labor production efficiency can be improved, and the medical fertilizer plays a positive role in promoting production investment reduction and vegetable production and income increase.

Description

technical field [0001] The invention belongs to the field of agriculture, and in particular relates to a carbon-based medicinal fertilizer for controlling root-knot nematodes and a preparation method thereof. Background technique [0002] Root-knot nematode disease can cause a 20-30% reduction in vegetable yields, and even result in a complete failure of vegetables. Root-knot nematodes have a wide range of hosts and hidden hazards. They occur within 5-30cm of the soil surface and are difficult to detect, which brings great benefits to the control. difficulty. At present, root-knot nematodes commonly occur in domestic vegetable production areas and tend to spread, and the occurrence of diseases is becoming more and more serious. In agriculture, chemical control is mainly used to control plant nematode diseases, but due to the high toxicity of most nematicides, It is unsafe for humans and animals, and some of them are also generally biocidal. Long-term use has a great impact ...

At present, root-knot nematodes commonly occur in domestic vegetable production areas and tend to spread, and the occurrence of diseases is becoming more and more serious. In agriculture, chemical control is mainly used to control plant nematode diseases, but due to the high toxicity of most nematicides, It is not safe for humans and animals, and some of them are generally killing, and long-term use will have a great impact on the environment
