I believe that the usual troubles of farmers’ friends are weeding. The traditional weeding is to remove the weeds with tools such as steamed bread. The advanced one is to use herbicides, but these methods are not only time-consuming and laborious, but may also damage crops. The environment will also have a certain impact. Then someone will ask, is there any other better weeding method besides herbicides? Xiaobian’s answer is of course, let’s come together.
First, the film weeding
The mulch film is very commonly used in agricultural production. In addition to the grass film, it is made by adding herbicide to the film production. This mulch can cover the ground, grow only crops, and not grow weeds.
Commonly used is the black grass film. At present, a variety of herbicidal films of colorless or colored have been introduced abroad, and the scope of use is expanding.
Second, weeding with fertilizer
According to experiments by foreign biologists, the application of an amino acid in weedy fields can increase the fertilizer of crops and kill the weeds in the field.
For example, Japanese farmers, during the fall of rice in the fall to November, in the continuous sunny day, the land will be ploughed twice, prompting the weed seeds to die. In every 0.67 hectares of paddy field, 1 ton of rice husk and 4 kg of oil residue can be sprinkled and evenly spread. When rice is planted in the second year, the rice husk rots, not only can fertilize the field, but also the rice husk leached in the rice husk. Lipids and phenolic substances can inhibit weeds from germination and make weeds in rice fields.
Third, the plant phase weeding
Plant weeding is the use of the characteristics of different plants to eliminate some weeds from certain crops.
For example, sunflower can effectively inhibit the growth of wild weeds such as mandala flowers and purslane. Sorghum can inhibit the growth of wild weeds such as S. serrata, switchgrass, and sorghum. In the field of crops in the morning or in the seedling garden, the cultivation of mangium can eliminate Xiaozhu; in the bamboo forest, hemp can be used to stop the spread of bamboo whip.
In addition to the three methods described above, there are novel weeding methods such as flame weeding, photochemical weeding, current weeding, etc. Although we have not touched these weeding methods for the time being, we can also try it. Maybe the weeding effect is better than weeding. The agent is better.
