Summer is the time to remove weeds in the field. How to do the weeding work? It is one of the most important aspects of our farming operations and lays a good foundation for the high yield of crops. So what should we pay attention to in summer weeding? Grasping the three elements of weeding in summer 1 According to the weather before weeding Why is it based on weather conditions? Because the temperature and humidity of the weather will largely determine the effectiveness of the herbicide (excluding the possibility of buying a fake herbicide). In general, weeding in summer, we choose to use the medicine before 9:00 am or in the evening on a cloudy or sunny day. Of course, you can't just consider the temperature. The humidity is also a factor to be referenced. Some parts of the high temperature in summer are prone to drought, which leads to unsatisfactory results of weeding. The reason is that weeds in dry weather will preserve their own water and enhance their resistance through various physiological operations, which is a self-protection mechanism of weeds. In this case, the herbicide is difficult to act on. Therefore, when the weather is dry, the water consumption should be increased; the wetting aid should be added during weeding. 2 weeding should be based on grass The older the grass, the greater the resistance. This is the common sense of our weeding, but we also have to be based on the actual situation. Weeds are too small, and the use of herbicides in the absence of unearthed soils has a powerful sense of powerlessness. Therefore, weeding is best when we choose weeds and three leaves. This situation can be avoided by the fact that most of the weeds have been released during this time. 3 weeding according to weed species There are many types of weeds, large changes, new weeds emerge in an endless stream, and resistance increases. Under such circumstances, we must recognize the types of weeds in the ground when weeding, so that it is convenient for the right medicine. Some agricultural friends feel that their weeding work is not in place, and some problems are here. When buying a herbicide, you should also purchase it in a targeted manner, instead of directly looking for a herbicide that has been heard to be good. Although some agricultural friends can also get the desired effect, this is obviously not the most correct approach, and it is easy to cause greater weed resistance.
