Embodiment 1

[0025] Routine shallow rotation, deep turning 30cm, no application, single or combined use of flufenacet and methylsulfuron-methyl treatment test.

[0026] Select plots with uniform fertility, spread the seeds of Jiejie wheat evenly on the ground, and design different treatments such as conventional shallow rotation and deep plowing of 30cm, and each district shall be treated as follows:

[0027] Treatment 1, conventional shallow rotation, no herbicide application;

[0028] Treatment 2, conventional shallow spin, spray soil with 41% flufenacet suspending agent after wheat sowing and before emergence, the dosage is 350g of active ingredient per hectare (the middle amount of registered usage);

[0029] Treatment 3, conventional shallow rotation, the 2-5 leaf stage stems and leaves of Azalea barley were uniformly sprayed with 30g / L Mesosulfuron-methyl dispersible oil suspension concentrate, and the dosage was 12g of active ingredients per hectare (the middle amount of the registere...

Embodiment 2

[0041] Deep turning 30cm, combined use of flufenacet and methylsulfuron-methyl treatment test.

[0042] Select plots with uniform fertility, scatter wheat seeds on the ground, plow 30cm deep, divide into zones, and treat each zone as follows:

[0043] After wheat sowing, 41% flufenacet suspending agent is used for soil spray treatment before emergence, and the stems and leaves of the 2-5 leaf stage of the wheat are evenly sprayed with 30g / L mesosulfuron-methyl dispersible oil suspending agent, using The dosage is as follows:

[0044] Treatment 1, flufenacet 300g, methylsulfuron 9g; treatment 2, flufenacet 300g, methylsulfuron 12g; treatment 3, flufenacet 300g, methylsulfuron 15.7g; treatment 4, flufenacet 350g, methylsulfuron 9g; treatment 5, flufenacet 350g, methylsulfuron 12g; treatment 6, flufenacet 350g, methylsulfuron 15.7g; treatment 7 , flufenacet 400g, methylsulfuron 9g; treatment 8, flufenacet 400g, methylsulfuron 12g; treatment 9, flufenacet 400g, methylsulfuron 15...

Embodiment 3

[0052] On the basis of Example 1, the deep plowing depth was changed to 20cm, and all the other treatments were the same as in Example 1, and the test was continued in the second year.

[0053] See Table 3 for the results of the investigation and test of wheat rejuvenation period.

[0054] Table 3 Effects of Different Treatments on the Occurrence Amount of Jeremiah (Second Year)

[0055]

[0056] It can be seen from the investigation and test results that if the wheat field continues to be conventionally shallow rotary tillage without control (treatment 1), the base number of knotty wheat will increase, and the damage will increase significantly. In the first year, 286.5 stems / m 2 , up to 588.5 stems / m in the second year 2 , causing significant yield loss to wheat. The use of disulfuron-methyl (or / and in combination with flufenacet) (treatment 2-treatment 4) in conventional shallow rotary tillage plots can control A. japonicus to varying degrees, but the control effect on...

Abstract

The invention belongs to the field of prevention and treatment of weeds, and discloses a method for preventing and treating aegilops tauschii cosson serving as distress weeds in a wheat field. The method comprises the following steps: atomizing soil with flufenacet using a deep tillage technology, andatomizing stems and leaves with mesosulfuron, wherein at the first year of using the deep tillage technology and the chemical herbicides, the aegilops tauschii cosson can be well controlled; after continuous use for 2 years, harm caused by the aegilops tauschii cosson can be basically controlled completely; after the third year, the aegilops tauschii cosson can be prevented and treated with or without herbicides; therefore, the harm caused by the aegilops tauschii cosson in the wheat field can be effectively controlled, and the use amount of the herbicides is reduced. Compared with a common herbicide for preventing and treating weeds, the method disclosed by the invention has the advantages of good prevention and treatment effect and relatively small use of the herbicide.

Description

technical field [0001] The invention belongs to the field of weed prevention and control, and more specifically relates to a method for preventing and controlling the vicious weeds in wheat fields. Background technique [0002] Wheat is one of the main food crops in my country. Its planting area and total output are second only to rice. The national planting area is more than 30 million hectares, about 450 million mu, accounting for 22% to 30% of the country's cultivated land area, which is about 20%~27% of the area, the total wheat output is about 100 million tons, reaching 22% of the total grain output (Wu Mingrong et al., 2013, Pesticides). It is the main commodity grain and strategic reserve grain variety in my country, and plays an important role in grain production, circulation and consumption. The development of wheat production is of great significance to the development of our national economy and people's lives. Azalea is a vicious weed in wheat fields, and it is t...
