The method of weeding in wheat field

Wheat is the staple food in the north of our country, and it is another major grain growing besides rice in our country. The resistance of wheat is very strong, but it still needs reasonable field management in order to obtain high yield. Weeding management in field management is a very important step, so how to weed in wheat field? Let's take a look at it next.

1. Weeding time

In the whole process of wheat growth, weeding usually needs to be carried out many times, and as long as the weeding is carried out at the right time, the weeds in the field can be eliminated as much as possible. Weeding is usually carried out in November every year and around February and March of each year. Other weeding time is mainly based on the growth of weeds in the wheat field to carry out reasonable weeding, used to reduce the loss of nutrients, so as to promote the growth of wheat.

2. Weeding methods

There are generally three methods of weeding, the first is ploughing, the second is manual weeding, and the third is weeding through pesticides. Intertillage weeding is generally used in the early stage of wheat seedling growth, which can enhance soil permeability, promote nutrient absorption and reduce nutrient consumption. Artificial weeding is generally a method of weeding in the later stage of wheat, because the wheat is basically close to maturity at this time, and if weeding in other ways will affect the yield and quality of wheat, so choosing artificial weeding is the most correct way of weeding. In the middle stage of wheat growth, we can use pesticides to weed, so that the weeds in the field can be eliminated to a great extent, so that the nutrients in the field can be completely absorbed and utilized by wheat seedlings, so as to increase the yield of wheat. it will not harm the quality of wheat.

3. Key points of weeding

Manual weeding is best selected on rainy days, so that the weeds in the fields can be pulled out easily, while weeding in the middle of ploughing is best chosen at noon on a sunny day, when the sun is relatively strong, so that the weeds removed will be killed by the sun, and it is not easy to grow new weeds. The best choice for pesticide weeding is to weed in the morning or noon on a cloudy day. At the same time, choose the appropriate pesticide when choosing pesticides.

4. Points for attention

The precautions of weeding in wheat field are mainly aimed at pesticide weeding, because if the pesticide is not used well, it will be a huge loss. First of all, when choosing pesticides, we should choose pesticides specially for weeding in wheat fields, and then we should choose a reasonable proportion of pesticides, and then choose a day without wind or a breeze when weeding, so as to prevent pesticides from blowing on the wheat through the wind, killing the wheat, and not weeding before the rain, so that the efficacy will be greatly reduced. Finally, weeding can not be carried out in sunny and hot weather, which will cause drug damage.
