Turfgrass nematode control method

Abstract

The invention discloses a turfgrass nematode control method which comprises the following steps: (1) preparation of turfgrass cultivation matrix: 5-15 cm deep fertile soil is evenly mixed, and is divided into two parts, wherein one part is used as inoculation soil, and the other part is disinfection soil which is implemented dry heat sterilization for two hours at the temperature of 160 DEG C; inactivated garbage composts and waste rubber particles with 0.5-1 mm particle size are additionally taken; the following raw materials are taken and are mixed evenly in parts by weight: 90-160 parts of inoculation soil, 140-260 parts of disinfection soil, 90-460 parts of garbage composts and 10-20 parts of waste rubber particles; (2) sowing of turfgrass; and (3) management and maintenance of turfgrass. The method can reduce soil compactness, bring convenience for movement of water in the soil, and modify water retaining property of the soil; and the garbage composts have an obvious restraining effect on plant parasitic groups, and can effectively kill and restrain breeding and growth of nematodes.

Description

technical field [0001] The invention belongs to the technical field of pest control, and in particular relates to a method for preventing and controlling lawn grass nematodes. Background technique [0002] Life has become more abundant, free time has increased, the construction of golf courses and football fields with large grasslands has gradually increased, and the cultivation area of ​​green agricultural products has also increased, and the nematodes existing in the soil have become a hot topic in the field of international ecological research. Frontier topic, Nematode-damaged turfgrass roots are impaired in their ability to absorb water and nutrients from the soil, requiring more frequent irrigation and fertilization, which wastes valuable freshwater resources and increases the risk of groundwater contamination by nitrates At the same time, nematodes also create ideal conditions for fungal disease outbreaks, leading to increased use of fungicides. The harm of nematodes ...

[0002] Life has become more abundant, free time has increased, the construction of golf courses and football fields with large grasslands has gradually increased, and the cultivation area of ​​green agricultural products has also increased, and the nematodes existing in the soil have become a hot topic in the field of international ecological research. Frontier topic, Nematode-damaged turfgrass roots are impaired in their ability to absorb water and nutrients from the soil, requiring more frequent irrigation and fertilization, which wastes valuable freshwater resources and increases the risk of groundwater contamination by nitrates , at the same time, nematodes also create ideal conditions for fungal disease outbreaks, leading to increased use of fungicides

The harm of nematodes weakens the competitiveness of turfgrass and weeds, which will increase the amount of herbicides used, and the amount of pesticides such as herbicides will also increase. Some harmful and toxic chemicals will inevitably enter the turfgrass, and then circulate. And in the final substance remaining, it will pose a threat to people's health, and at the same time it will cause soil compaction, soil fertility will decline, and the soil environment will be greatly damaged
