There are many weeds in the field. Is there any good way to solve it besides weeding?

When applying herbicides to wheat, the average daily temperature must be above 6℃, and the soil should not be too wet and there should be no water accumulation. At present, the highest temperature in the north is below 0℃, and the soil moisture content is high. It has snowed in some places, but there is more rain in the south, so herbicide is applied to wheat: the lowest temperature in winter is above 0℃, and the highest temperature is165438+1early October.

According to past experience, wheat seedlings grow vigorously in rainy weather and the weather is cold. There are few weeds in wheat seedlings. When the temperature rises, it will be exposed in a large area. If you want to use herbicides, you need to use more weeds if you don't plant wheat next season.

The weather is getting warmer these days, and this situation may have to be adapted to local conditions. For example, the temperature in northwest Shandong is now a few degrees below zero, and no matter how many weeds there are, herbicides can only be used because the average temperature is above 6 degrees.

Herbicide must be used, and when to use it may be different from place to place.

Tell me about my residence. My location is in the southwest of Henan. Herbicide is usually used around the New Year. I don't know when you will use it.

The temperature is suitable before jointing after the wheat turns green next year.

After wheat germinates, herbicides cannot be used. If herbicides are used at this time, the wheat may be removed together. It's too dangerous. The grass in my field is usually carved from artificial roots. When you use herbicides, grass will be removed and wheat will be removed as usual. Whether wheat covers the ground or not, low temperature is not conducive to spraying herbicides, because it is in winter solstice. When the temperature rises in the next spring, it is necessary to avoid the cold in spring and reduce the harm of herbicides, so as long as some weeds are still doing the right thing for people. Such as Lala grass, wild Lycium barbarum, hook hook seedlings, Cyperus tuber and so on. These weeds are deeply rooted and difficult to control. Even after applying herbicides, some weeds still fall off.
