Embodiment 1

[0026] The herbicide is used to control weeds in the North Adenophora ginseng field. The main active ingredient of the herbicide is fomesafen, and the dosage is 225-375g a.i / hm 2 , Can be compounded with the herbicide quizalofop-p-ethyl for controlling gramineous weeds according to needs, the dosage is 37.5-67.5g a.i / hm 2 . After using this method, it can effectively control broad-leaved weeds and gramineous weeds in the field of Adenophora sylvestris. It has better control of common weeds such as foxtail, cocory, artemisia spp. effect.

Embodiment 2

[0028] The method for controlling weeds in the A. sylvestris field in this embodiment is specifically as follows:

[0029] 1) Before sowing the North Adenophora ginseng, the soil in the planting area should be deeply plowed, raked, finely leveled, and then sowed. After sowing, cover with shallow soil or plant ash 1-2cm to suppress;

[0030] 2) Before the seedlings of Adenophora ginseng after sowing, use metolachlor according to the dosage 1080g a.i / hm 2 , Or use acetochlor according to the dosage 500-1000g a.i / hm 2 For soil spray treatment, the water consumption per hectare is 450-750L, and the equipment is a knapsack pressure sprayer or a hand-held electric sprayer. Maintain the relative soil moisture content of 70%-90% 2 days before spraying;

[0031] 3) Cover with straw, mulching film, etc. one week after the soil spray treatment.

[0032] 4) At the 3-4 leaf stage after emergence of Adenophora Adenophora, the stem and leaf spray treatment is carried out with the herbicide of Adenop...

Abstract

The invention belongs to the technical field of weed control and in particular relates to a weed killer and a weed control method which are applied to radix glehniae field. For solving the weed harm problem of the radix glehniae field, especially the problem of harm of broadleaf weeds in a seedling stage of radix glehniae on the safety basis of the radix glehniae, the weed killer applied to the radix glehniae field contains a fomesafen active ingredient. The radix glehniae field weed killer provided by the invention can be safely used in the radix glehniae field, the broadleaf weeds in the field after seedling emergence of the radix glehniae are prevented and killed off, and safety on the radix glehniae crops is high and pertinence is strong while the broadleaf weeds are prevented and killed off. The invention also comprises a weed control method for the radix glehniae field. Control effects of physical, chemical and agricultural measures on weeds are comprehensively utilized, growth vigor of radix glehniae seedlings is improved, the growth vigor of the weeds is inhibited, and optimized service conditions are beneficial to improvement of chemical weeding effect and safety on the radix glehniae.

Description

Technical field [0001] The invention belongs to the technical field of weed control, and specifically relates to a herbicide and a weed control method used in the A. sylvestris field. Background technique [0002] Adenophora glabra is a broad-leaved perennial herbaceous crop. It is the dry root of Glehnialittoralis Fr. Schmidt ex Miq, a plant of the Umbelliferae family. It is mainly distributed in Shandong, Hebei, Liaoning, Jiangsu and other places. It grows on beaches or beaches. Cultivated in fertile and loose sandy soil, the production cycle is 2-3 years. The autumn sowing seeds of Adenophora sylvestris emerge in March the next year, and the seedlings emerge 2-4 weeks after the seeds are sown in spring. Due to the slow growth in the seedling stage of Adenophora sylvestris, the field weeds in the field of Adenophora ssp. Because of its strong growth potential, Adenophora adenophorum is very vulnerable to the competitive harm of weeds. It is manifested in that the field of Aden...
