Description
Technical Field
The invention relates to the technical field of peony planting, in particular to a method for accurately controlling weed removal time of a herbicide for controlling peony weeds and protecting plants and applying the herbicide.
Background
Peony is a perennial deciduous shrub belonging to the genus Paeoniaceae, the class Dicotyledoneae. The stem is up to 2 meters; the branches are short and thick. The leaves are usually two-time-three-time-multiple leaves, the surface is green and unhairing, the back is light green, sometimes white, the petioles are 5-11 cm long, and the axes of the leaves are unhairing. The peony has beautiful color, beautiful appearance, beautiful smile and fragrant, natural and unrestrained style, grandeur and beautiful reputation of 'king in flower'. Among the types of cultivation, hundreds of varieties can be classified mainly according to the color of flowers. The peony has various varieties and colors, takes yellow, green, flesh red, dark red and silver red as top grade, and is particularly noble in yellow and green. Peony is large and fragrant, so it is called "very beautiful and fragrant". The newly planted peony has relatively serious weed damage in 1-2 years due to small leaf area, but the application effect of the existing chemical herbicide is poor, and if the purpose of controlling the weed damage is achieved, the peony needs to be applied for many times in one year, so that the damage to soil and plants is large; and artificial weeding and soil loosening and ventilation functions are added, so that the peony cultivation bag is beneficial to the growth of the peony. Therefore, the application of chemical herbicides to peony fields is generally not advocated for weed control, and especially in spring with vigorous weed growth, artificial weeding is mainly used, which causes the defect of high labor cost for planting peony.
Disclosure of Invention
The invention aims to provide a method for accurately controlling weed killing time and using herbicide to prevent and control peony weeds and protect plants, which has the advantages of treating soil by using the herbicide before planting and killing weeds by using the herbicide again in the season of vigorous growth of the weeds, and solves the problems that the application effect of the existing chemical herbicide is poor, and the herbicide is applied for many times in one year and has great harm to soil and plants if the purpose of controlling weeds is achieved; and artificial weeding and soil loosening and ventilation functions are added, so that the peony cultivation bag is beneficial to the growth of the peony. Therefore, the application of chemical herbicides to peony fields is generally not advocated for weed control, and especially in spring with vigorous weed growth, artificial weeding is mainly used, which causes the problem of high labor cost for planting peony.
In order to achieve the purpose, the invention provides the following technical scheme: a method for accurately controlling weed removal time and using a peony weed control herbicide for plant protection comprises the following steps:
s1, preparing a pre-emergence herbicide from acetochlor, butachlor, metolachlor and water according to a proportion;
s2, uniformly spraying the prepared preemergence herbicide on the surface layer of the soil to be planted by using an agricultural sprayer, and then carrying out peony planting operation;
s3, uniformly spraying the post-emergence stem leaf herbicide of the peony field on the leaf surfaces of the weeds when the weeds are in a 3-5 leaf period after the peony leaves are stretched;
and S4, performing weeding management by using the post-emergence foliage herbicide of the peony field at proper time when the weeds are in a 3-5 leaf stage according to the growth condition of the weeds at irregular intervals.
Preferably, the acetochlor accounts for 1 to 3 percent, the butachlor accounts for 1 to 3 percent, the metolachlor accounts for 1 to 3 percent, and the balance is water.
Preferably, the water spray is determined according to the soil moisture content, so that the soil is kept moist when the pre-emergence herbicide is sprayed.
Preferably, the spray head is pressed down as much as possible when the crop is in the seedling stage and the plant is short, so that the pesticide is uniformly sprayed on the weeds, and the weeds are prevented from raining within at least three days after the spraying by paying attention to weather conditions when the pesticide is applied at drought, high temperature and low temperature, wherein the using time is three or four points in the afternoon.
Preferably, the post-emergence foliage herbicide of the peony field is diluted by water when in use, and the ratio of the herbicide to the water is 1: 500.
compared with the prior art, the invention has the beneficial effects that: before planting, the soil is treated by using a preemergence herbicide which uses acetochlor, butachlor and metolachlor, wherein the acetochlor can be absorbed by plant buds and interferes with nucleic acid metabolism and protein synthesis in plants to stop the growth of the buds and roots, new leaves shrink and the other leaves shrink and the whole plants die after being damaged by the gramineous weeds; butachlor is mainly absorbed by buds of weeds and then conducts the whole plant to play a role, the butachlor can be used before the buds and in the seedling stage, after the plants absorb the butachlor, protease is inhibited and destroyed in vivo, the formation of protein is influenced, and the normal growth and development of the buds and the roots of the weeds are inhibited, so that the weeds die, the butachlor herbicide is used on soil with higher organic matter content, the herbicide can be absorbed by soil colloid and is not easy to be leached, the special effect period can reach 1-2 months, the herbicide is applied in the early field under the condition of soil wetting, and the annual gramineous weeds and some dicotyledonous weeds can be prevented and removed; metolachlor is absorbed by buds and conducted upwards to inhibit the growth of the buds and roots, an action mechanism is mainly used for inhibiting the protein synthesis of germinated seeds, choline is inhibited from permeating phospholipid to interfere the formation of lecithin, weed seedlings are killed by various preemergence herbicides, and the weeding frequency of the peony in the later planting period is reduced.
