How to remove weeds and trees?

You can use "glyphosate."

Isopropylamine salt". Trees can be selected by the Dow Chemical Company of the United States.

Cover the shrub forest 520 emulsifiable concentrate or poison herb water determination agent 25 times the solution, spray low shrubs (miscellaneous trees).

Taking advantage of the excellent conductivity of the above-mentioned drugs, the protein synthesis of the active ingredient is completely withered from the underground part to the aboveground part.

For tall trees, you can use an axe to cut a ring at the stem of the tree, deep into the xylem.

Then spray (coat) the cut mark with 1 times the liquid solution. For miscellaneous trees with a DBH of less than 20 cm, the stem of the tree was sprayed with a diluted solution of 5 times 100 cm (counted upwards from the ground) and died about 60 days after receiving the medicine from the miscellaneous tree.

Oh, no matter what type of herbicide it is, there will be residues and long drug residue periods, and the disappearance of trees that want to hinder the environment is very simple, and the sulfuric acid can be brushed around the trunk, of course, everyone is responsible for protecting trees.

With herbicides, systemic and multi-spraying, it can die, but herbicides are easy to produce pesticide damage, and some have a long residual period, so pay attention to it.

Planting crops in a weed field is the best way to get rid of weeds.

The complete removal of weeds is as follows:1. Use a shovel, using a shovel to remove weeds is the easiest way, we use a gardening shovel to shovel the weeds little by little, although this method can shovel the weeds relatively clean, but it is more energy-consuming and time-consuming.

2. Remove the flowers and seeds, if you want to make the weeds at home less and less, you can pull out all the flowers of the weeds during the flowering period and the seed-bearing period, because once the weeds bloom, they will begin to multiply and spread. In addition, some flower friends like to use weeds for composting, which will also lead to the spread of weeds.

3. Spread plastic film, when we raise flowers in the yard, if it is the season when the plant grows more vigorously, we can spread a little plastic film on the ground, which can prevent the growth of weeds, and also has the effect of heat preservation and moisturizing.

Weeds inside the greenery are treated by sanitation workers. Greening, planting Activities that plant plants to improve the environment. Greening refers to the planting of shelterbelts, roadside trees, crops, and various plants in residential areas and parks.

Greening includes land greening, urban greening, greening on all sides and road greening. Greening improves sanitation and plays a variety of roles in maintaining ecological balance.

Related Notes:Urban three-dimensional greening is one of the important forms of urban greening, and it is an important and effective way to improve the urban ecological environment and enrich the urban green landscape. The development of three-dimensional greening can enrich the spatial structure level of urban landscaping and the artistic effect of urban three-dimensional landscape, help to further increase the amount of urban greenery, reduce the heat island effect and dust absorption, reduce noise and harmful gases, and create and improve the urban ecological environment.

In addition, as a living environment for urban residential landscaping, the first thing to understand is the requirements of the residents of the community, that is, the greening and landscaping of the residential area should consider the requirements of the residents' life and leisure to the greatest extent. In the greening of residential areas, we should not only take into account the elements of beauty, but also fully consider the needs of the main body in the residential area - people, only to understand this need, and then design from this need, carry out the necessary beautification treatment, in order to achieve the effect of residents' satisfaction.

<> to completely remove weeds, it is necessary to control the seeds, roots, stems, etc. of weeds in the field. You can dig deep into the land and remove the rhizomes of weeds, and you must cut the weeds and remove the roots, not just the leaves of the surface weeds. Weeding should be done frequently to prevent weeds and crops from stealing nutrients.

Herbicides can also be used to spray the soil with herbicides to prevent weeds from growing before planting crops.

The growth of weeds is not conducive to the growth of grain, and weeds in farmland compete with crops for fertilizer, light, water and space. Farmland weeds can also reduce the yield and quality of crops, such as the toxic effect of flour from poisonous weeds mixed with wheat.

Farmland weeds can also breed diseases and pests, so be cautious of infiltrating some weeds and infecting them with viruses through insects, and then insects will spread the viruses on the weeds to crops. Weeds are the most harmful at the seedling stage, if the crops grow taller after manual or chemical weeding at the seedling stage, and the weeds grow out again, they are shaded by the crops, and they will not grow.

With the rapid development of China's agriculture and forestry industry, a variety of pesticide products began to appear in large quantities, among which herbicides have become one of the rapidly developing products. As one of the essential products for forestry and landscaping, tree herbicides have also achieved rapid development. However, until now, there are still many people who are not very clear about the product characteristics and how to use tree herbicides.
