A kind of organic vegetable root watering agent and using method thereof

Abstract

The invention discloses a root-watering agent for organic vegetables and a method for using the root-watering agent. The root-watering agent is composed of fresh leaves of Tripterygium wilfordii, fresh leaves of Polygonum capericum and tea seed dregs. The fresh leaves of Tripterygium wilfordii and fresh leaves of Polygonum pepper , The mass ratio of tea seed meal is a compatible mixture of 2.0~3.0:1.0~2.0:0.5~1.0, the preferred ratio is 2.5:1.5:0.75. Based on the weight of dry cakes that are not mildewed and hygroscopic for 1 to 30 days, tea seed meal needs to be added with water at a ratio of 1:10 to make tea seed meal fermentation liquid, which is used as an auxiliary agent and also as a brewing medium , this compatible brewing solution is the stock solution. The compatibility agent has remarkable control effect on organic vegetable root-knot nematode and has synergistic effect. Before or during the outbreak of vegetable root-knot nematode, watering with 15 times of stock solution per 667m25-15kg can kill root-knot nematode quickly, prevent the spread and speed up the recovery of plants. The root watering agent is easy to use in production, 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.
