Organic vegetable root watering agent and using method thereof

Abstract

The invention discloses an organic vegetable root watering agent and a using method thereof, the organic vegetable root watering agent is a compatible mixture prepared by compatibility of fresh leaves of thunder god vine, fresh leaves of red-knees herb, and tea seed meal, wherein the mass ratio of the fresh leaves of thunder god vine, the fresh leaves of red-knees herb and the tea seed meal is 2.0-3.0:1.0-2.0:0.5-1.0, and is preferably 2.5:1.5:0.75, the fresh leaves of thunder god vine and the fresh leaves of red-knees herb are weighed freshly, the tea seed meal is weighed according to the 1 to 30-day non-mildewed and non-moistened dry cake weight, the tea seed meal is first prepared into a tea seed meal fermented liquid by adding water in the proportion of tea seed meal to water of 1:10, the tea seed meal fermented liquid is used both as an assistant and an infusion medium, and the compatible infusion liquid is the concentrate liquid. This compatible agent has remarkable control effect on organic vegetable root knot nematode, and has synergic effect. Before and during the outbreak of the root knot nematodes in vegetables, 15 times of 5-15 kg per 667 m<2> of the concentrate liquid are applied by watering, the root knot nematodes can be quickly killed, the spread is prevented, the plant recovery is speeded up, and the organic vegetable root watering agent is easy to produce and use, simple to operate, low in cost, and remarkable in control effect.

Description

technical field [0001] The invention belongs to the development and application of new agricultural practical technologies; the invention relates to a method for the development, production and application of an organic vegetable root watering agent. Background technique [0002] Vegetable root-knot nematode {Meloidogynespp, Root-knot nematodes) is an obligate parasite parasitic in the root system of plants. It has a wide range of hosts, strong adaptability, and strong reproductive ability. It has a relatively large impact on modern agricultural production and development. and hazards. With the increase of vegetable planting area in our country, the occurrence of vegetable root-knot nematode disease has increased year by year. After the disease occurs, the yield generally decreases by 20%-30%, and in severe cases it reaches more than 75%, or even no harvest. According to relevant statistics, the economic loss of crops caused by root-knot nematode damage is more than 100 bil...

Problems solved by technology

In 2011, a variety of vegetable crops were found to be infected with root-knot nematodes in the vegetable base of Songbu Town, Macheng City, Hubei Province, causing serious economic losses

Physical control is time-consuming and labor-intensive. Biological control has not yet bred high-efficiency bacteria agents. Although chemical control has good chemical agents, chemical agents cannot be used in the production of organic vegetables. It is strictly forbidden to use them in organic vegetable production, so their use is limited.
