Since the types of the ophiopogon japonicus lawn are various in the day, in the process of planting the lawn, the survival rate of the ophiopogon japonicus lawn is caused by the influence of weeds such as goosegrass, green bristlegrass and chickweed with tough roots in the gramineous weed category, the lawn appearance effect is poor, and the ophiopogon japonicus lawn weeds grow disorderly, so that the ophiopogon japonicus lawn has to be planted again.
At present, the special herbicide for the dwarf lilyturf root lawn is mainly adopted to prevent and kill weeds in the dwarf lilyturf root lawn, such as a high-efficiency haloxyfop herbicide or a fluroxypyr herbicide; conventionally, haloxyfop-R-methyl is a novel stem leaf treating agent with optical activity, has faster acting speed and stable drug effect, is not easily influenced by the conditions such as drought, temperature, rainwater and the like, is absorbed by weed stem leaves, conducts upwards and downwards in a plant body in two directions, accumulates at the top and in the middle, causes the inhibiting effect on the synthesis of cell fatty acid, and finally leads the death of weeds. The haloxyfop-R-methyl is a stem and leaf treating agent with very high selectivity, has better selectivity between gramineous weeds and dicotyledonous crops, and has very obvious control effect on gramineous weeds in the ophiopogon root lawn; fluroxypyr belongs to a pyridyloxyacetic acid herbicide, belongs to a typical internal absorption conduction type herbicide, has a post-drug reaction of a hormone herbicide, can be quickly absorbed by weeds, and is conducted to all parts of the whole plant, so that the plant is deformed, distorted and finally died.
