Problems solved by technology

Corn has a large planting area in my country and produces a large amount of corn stalks, but the use value of the stalks is not high. A large amount of crop stalk wastes are often incinerated after they are produced, causing serious air pollution and bringing safety hazards at the same time
Although straw returning to the field is popularized in production, cellulose cannot be effectively decomposed and integrated into the soil, and straw is difficult to absorb and utilize
However, if a large amount of straw simply buried in the soil cannot be used in a short period of time, it will breed a large number of diseases and insect pests and cause serious harm to agricultural production.

Embodiment 1

[0030] Step (1): Collect discarded corn stalks in the field and crush them. Take a 30kg (height 43cm, diameter 32cm) empty plastic bucket, add crushed corn stalks while adding water and stir evenly to make the corn stalks fully moist and achieve Hold the state with a small amount of water oozing tightly, and finally press the corn stalks in the bucket tightly, and fill the entire plastic bucket; at this time, a total of 2kg of corn stalks and 6kg of water are loaded.

[0031] Step (2): add a double-layer cover to seal, carry out anaerobic fermentation at room temperature, during which oxygen and water are not supplemented, and the fermentation product is obtained after 5 months.

[0032] Step (3): Preparation of Extract

[0033] Step a: Take 0.5 kg of decomposed corn stalk compost, put it in an empty plastic bucket, then add 1 kg of water, stir well, make the compost completely submerged in water, then seal it with a double-layer cover, and extract it at room temperature.

Abstract

The invention provides a preparation method of a compost extract for inhibiting of second instar larvae and ova of root-knot nematode as well as a control method. The preparation method comprises the following steps: step A: composting treatment: collecting waste corn straws in the field, pulverizing the waste corn straws in a plastic barrel while adding water and uniformly stirring, enabling the corn straws to be fully moistened, compressing the corn straws in the barrel, and enabling the whole plastic barrel to be full; step B, capping for sealing, conducting anaerobic fermentation at the ordinary temperature without oxygen and moisture supplement; step C: preparation of the extract, placing the obtained extract in a refrigerator to be preserved for standby, and using the extract as a stock solution for experiment. Not only is the problem of treatment of a large number of agricultural waste straws after the production solved according to the preparation method, but also the invention further provides a novel control method for root-knot nematode of plant; the control method is utilized for solving a series of problems of environmental pollution, food unsafety and the like caused by the conventional chemical nematicide for treating the root-knot nematode of vegetables.

Description

technical field [0001] The invention belongs to the field of root-knot nematode prevention and control, and in particular relates to an extract liquid obtained by composting agricultural waste to prevent and control vegetable root-knot nematode and a control method thereof. Background technique [0002] Vegetable root-knot nematode disease is an important soil-borne disease in production. The disease has a wide range of hosts, especially Solanaceae, Cucurbitaceae and other plants are more common. In recent years, with the adjustment of industrial structure, the planting area of ​​vegetable protection land has been expanding continuously. Due to the particularity of the soil conditions, cultivation and management measures in the facility, the incidence of root-knot nematodes is much heavier than that in the field. It is estimated that the damage to vegetables caused by nematode diseases in China has reached more than 3 billion yuan. [0003] At present, the methods of contr...
