Last Updated: 2024/11/22, (1) rotation: reduce the density of associated weeds, change the dominant weed community in the field, and reduce the number of weeds in the field. (2) ploughing: after ploughing the soil for many times, perennial weeds such as Ixeris angustifolia are buried in the ground, so that the weeds gradually reduce or decline, so that their growth is inhibited and the purpose of weeding is achieved. (3) ploughing and soil cultivation: this measure not only removes weeds, but also has the functions of deep loosening, storing water and preserving soil moisture. For example, the potato in the open field is ploughed for the first time at about 10cm of seedling height.

(1) rotation: reduce the density of associated weeds, change the dominant weed community in the field, and reduce the number of weeds in the field.

(2) ploughing: after ploughing the soil for many times, perennial weeds such as Ixeris angustifolia are buried in the ground, so that the weeds gradually reduce or decline, so that their growth is inhibited and the purpose of weeding is achieved.

(3) ploughing and soil cultivation: this measure not only removes weeds, but also has the functions of deep loosening, storing water and preserving soil moisture. For example, the cultivation of potato in open field is generally carried out at about 10cm of seedling height for the first time, and the second time is completed before ridge closure, which can effectively control weeds such as thistle, Niufan, paspalum grass, amaranth and so on.

(4) artificial weeding: suitable for pulling out small areas or large grasses.

(5) physical method of weeding: for example, mulching with colored plastic film, such as black film and green film, has a certain anti-weed effect.
