Problems solved by technology

[0003] At present, the main means of controlling root-knot nematodes are chemical control and biological control. The pesticides used in chemical control are highly toxic and pollute. Continuous use will easily increase the drug resistance of pathogenic nematodes, and gradually cannot meet the development needs of modern agriculture.
In terms of biological control, the biocontrol fungicides with Paecilomyces lilacinus as the main component have been widely used in the control of root-knot nematodes, but these fungicides have some shortcomings, which greatly limit the use of Paecilomyces lilacinus. Application, mainly in: ①The existing bacterial agents mainly exist in the form of granules, powders, and bacterial blocks, and the shelf life is short; in actual use, they are easily affected by the soil environment, and it is difficult to form a stable bacterial group, and the control effect is unstable
② In terms of use, Paecilomyces lilacinus fungicides are mostly applied in acupoints. For example, the patent No. CN201110176515.3 discloses a smart bacterial block containing Paecilomyces lilacinus and its preparation method. The root system of the plant has a limited range of action and cannot protect the root system of the plant in a three-dimensional and all-round way, and the control effect is greatly reduced

Abstract

The invention discloses a degradable seedling-raising pot preventing and treating root-knot nematodes and a preparation method thereof and belongs to a cultivating container. The degradable seedling-raising pot is applied to the agriculture pest and disease green prevention and control field. The main ingredients of the seedling-raising pot comprise 5-10% of paecilomyces lilacinus solid state fermentation products, 10-20% of diatomite, 5-15% of nutrient substance, 30-40% of crop straw, 30-40% of clayed soil and 1-1.5% of sodium carboxymethylcellulose, and the components are manufactured according to specific procedures. According to the degradable seedling-raising pot, the paecilomyces lilacinus solid state fermentation products are added to the manufacturing raw materials of the seedling-raising pot, so paecilomyces lilacinus can be effectively protected, shelf lives and a lasting period of a product are prolonged, utilization efficiency of the paecilomyces lilacinus is improved, and plants can be protected in a three-dimensional and all-round mode.

Description

technical field [0001] The invention relates to a cultivation container, in particular to a method using Paecilomyces lilacinus (Paecilomyces lilacinus) A degradable nursery pot for preventing and controlling root-knot nematodes and a preparation method thereof. Background technique [0002] root knot nematode (Meloidogyne spp.) It is one of the most harmful and widely distributed plant pathogenic nematodes, and the annual economic losses caused by root-knot nematodes in the world are as high as more than 100 billion US dollars. [0003] At present, the main means of controlling root-knot nematodes are chemical control and biological control. The pesticides used in chemical control are highly toxic and pollute. Continuous use will easily increase the drug resistance of pathogenic nematodes, and gradually cannot meet the development needs of modern agriculture. In terms of biological control, the biocontrol fungicides with Paecilomyces lilacinus as the main component have ...
