Oil-used peony field weeding method

Abstract

The invention relates to an oil-used peony field weeding method. The method mainly comprises herbicide selection, a spraying method, and weeding time. The herbicide is a mixture of carfentrazone-ethyl, haloxyfop-R-methyl, prometryn, an assistant, and a packing. Weight percentage of each raw material is 1-5% of carfentrazone-ethyl, 3-15% of haloxyfop-R-methyl, 2-30% of prometryn, 2-10% of assistant, 40-92% of packing. The spraying method of the herbicide is using a sprayer added with a sprayer cover to spray in a targeted manner. First weeding time is selected in spring, when air temperature is low and wind is small, and later, the herbicide is sprayed in time according to weed conditions. The weeding method can effectively remove broad-leaf family, grass family, and sedge family common weeds in an oil-used peony field. The method is high in control effect, and fast in response. The sprayer added with a sprayer cover is used to spray, thereby effectively preventing damages on growth of the oil-used peony.

Description

technical field [0001] The invention relates to the field of peony cultivation for oil, in particular to a field weeding method for peony for oil. Background technique [0002] Peony for oil is a new kind of woody oil crop, which has the outstanding characteristics of "three highs and one low": high output (the yield per mu can reach 300 kg in five years, and the comprehensive benefit per mu can reach 10,000 yuan), high oil content (seed oil content 22%), high quality (unsaturated fatty acid content 92%), low cost (peony for oil is drought and barren resistant, suitable for afforestation and forest planting on barren hills; planted for one year and harvested for a hundred years, low cost). [0003] For the newly planted oil peony, the weed damage is relatively serious due to the small leaf area in the first to second year, but the application effect of the existing chemical herbicides is poor. To achieve the purpose of controlling the weed damage, more If it is used for the...

Problems solved by technology

[0003] For the newly planted oil peony, the weed damage is relatively serious due to the small leaf area in the first 1-2 years, but the application effect of the existing chemical herbicides is poor. To achieve the purpose of controlling weed damage, more If it is used for only one time, it will cause great damage to the soil and plants; in addition, artificial weeding can also loosen the soil and breathe, which is beneficial to the growth of peony

Therefore, it is generally not recommended to use chemical herbicides to kill weeds in peony fields, especially in the spring when the growth of weeds is not vigorous, weeding should be done manually, which has caused the disadvantage of high labor costs for oil peony planting
