Embodiment 1

[0030] Embodiment 1: A cultivation substrate disclosed by the present invention comprises leek extract and nutrient soil. Further, the mass ratio of leek extract to nutrient soil is 1:10. Preferably, the nutrient soil includes peat soil, vermiculite and perlite, and the mass ratio of peat soil, vermiculite and perlite is 2:1:1. In the present invention, the nutrient soil can be replaced by other substrates such as rice husk, wheat husk or crushed straw thereof.

[0031] In the cultivation medium of the present invention, the leek extract and the nutrient soil can be mixed according to any mass ratio, and both have the effect of preventing and controlling root-knot nematodes. When the leek extract is mixed with the nutrient soil, the main consideration is that the amount of liquid in the nutrient soil is too small Or too much, all can easily produce the phenomenon of drought and flood, as long as the amount of liquid in the nutrient soil is properly grasped, so those skilled i...

Embodiment 2

[0067] Embodiment 2: A method for preparing the cultivation substrate disclosed in the present invention comprises the following steps,

[0068] (1) Prepare leek extract:

[0069] (2) Uniformly mixing the leek extract prepared in step (1) with nutrient soil to obtain a cultivation substrate.

[0070] Further, in step (2), the mass ratio of leek extract to nutrient soil is 1:10.

[0071] Further, the specific operation steps of step (1) are as follows: ① cut the above-ground part of leek into 4-6cm segments, weigh 200g and add it to 200mL water; , let stand for 24 hours, get the leek extract after getting the supernatant and filtering.

[0072] Further, the nutrient soil in step (2) includes peat soil, vermiculite and perlite, and the mass ratio of peat soil, vermiculite and perlite is 2:1:1.

[0073] The time for mixing the leek extract and the nutrient soil in step (2) is 22-24 hours. In the technical solution, the uniform mixing time of the leek extract and the nutrient ...

Abstract

The invention discloses a culture medium. The culture medium comprises fragrant-flowered garlic extracting liquor and nutrient soil. The culture medium has the advantages that the culture medium is adopted to carry out cultivation, so that occurrence of root-knot nematode diseases can be remarkably lowered; besides, operation is simple and convenient and economic cost is lower; the culture medium is applied to preventing and controlling the root-knot nematode diseases, so that not only is environmental pollution caused by applying a chemical agent to prevent and control in the prior art avoided for achieving high efficiency, environmental protection and no harm, but also the defect that economic income is severely affected by a long prevention and control period, regional limitation, and the like, caused by rotation planting of the fragrant-flowered garlic is overcome, and normal growth of plants is kept, so that yield of plant products is improved, product quality is improved, higher economic value is brought, and therefore, the culture medium is worthy of large-area popularization and application.

Description

technical field [0001] The invention relates to the field of biological prevention and control of plant diseases, in particular to a cultivation substrate and its preparation method and application. Background technique [0002] Root-knot nematode (Meloidogyne spp.) is an important disease that can attack more than 5,000 kinds of plants, mainly because its second-instar larvae invade the roots of plants, enter the vascular bundles and induce cell division into giant cells, forming root knots, which seriously prevents plant growth. The absorption of water and nutrients causes the plants to show nutritional imbalance, chlorosis and dwarfing, etc., resulting in reduced plant yield and reduced product quality. According to reports, the global annual damage caused by root-knot nematodes to crops is about 100 billion US dollars. [0003] Currently, the most effective ways to control root-knot nematodes are the use of chemical agents and crop rotation with non-host crops. For man...
