Ground weeds especially, in addition to playing herbicides there is no good way to solve?

Wheat playing herbicides, must be the average daily temperature above 6 ° C, and the soil can not be too wet, can not have stagnant water, but right now the highest temperature in the north are below 0 ° C, the soil water content is larger, some places are already freezing, and the south of the rainfall is more, wheat playing herbicides: about the winter in the first half of November, the lowest temperature above 0 degrees, the highest 10 degrees, (the temperature is too low), weeds 2-4 leaf period is the best. Spraying will produce drug damage, and the efficacy is not good), weeds 2-4 leaf stage is the best.

Based on past experience, rainy wheat seedlings grow strong, coupled with the cold weather, weeds are still very small in the wheat seedlings, and so the temperature rises after a large area will be revealed, herbicides are to be played, a year does not play to the next season when planting wheat will be more.

The weather in the past few days to rise some, this situation may have to be adapted to the local conditions, such as our northwestern region of the temperature is now several degrees below zero, no matter how many weeds can not play herbicides, because herbicides must be in the average air temperature of more than 6 degrees in order to play.

Herbicides are a must, when to play, each place may not be the same.

Speaking of my place, my location in the southwestern part of Henan, the herbicide is usually played around the New Year, I do not know when you play

In the next year after the wheat is green before the plucking, the temperature is suitable.

Wheat germination out of the wheat is not to hit the herbicide, if this time to hit the herbicide, there is a possibility that the wheat will be removed together, this is too dangerous, my family's field of grass is generally manual shoveling, hit the herbicide, the grass are removed, the wheat will also be removed, regardless of whether the wheat is tracked to cover the ground, due to the current in the winter solstice, the temperature is low unfavorable for the spraying of herbicide, to be the coming of the spring temperature rebound. The beginning of spring temperatures rise, do to avoid the inversion of spring cold, so that wheat to reduce the herbicide damage, so as long as the temperature of 5 degrees or more only no cold air to come, vegetables, Brahmi, such as the wheat before the wheat is not much to see. However, there are some rooted weeds that are still giving a right. For example, Lala grass, wild goji berry tree, hooked seedlings, balsam and so on. These weeds are deep-rooted and difficult to treat. Even after a herbicide, some weeds are still shed.
