How to loosen the soil and weed mint?

Weeding by loosening the soil with mint: when the seedling height is about 10 cm, or after the planted seedlings survive, it needs intertillage weeding 1 time, and then it needs to be done for the second time before closing the ridge, and both times it needs shallow tillage. After the first harvest in July, it is necessary to carry out the third intertillage in time, which can be slightly deeper and remove some rhizomes to avoid being too dense. Carry out the fourth time in September, only weeding without intertillage; After the second harvest in June+10, 5438, the fifth harvest should be carried out and some rhizomes should be removed. After planting mint for 2 ~ 3 years, it needs to be planted in different places.

In the spring of the second and third years, when the seedling height is 12 ~ 18 cm, weeding should be combined to remove the over-dense seedlings, and leave 1 seedling every 10 cm. After that, intertillage weeding is the same as in the first year.

After the weeds are unearthed, the stems and leaves can be treated with herbicides. During the 4-6 leaf stage, monocotyledonous weeds were controlled with 65,438+02.5% Gaicaoneng 65,438+000g/mu, and dicotyledonous weeds were controlled with 40% Bentazon 65,438+050g/mu.
