Wheat herbicide time, can it be used at the same time as urea?

The suitable time for herbicide treatment for wheat is the tillering stage of wheat before winter and the early stage of jointing of wheat in the second year, the control effect of herbicide in these two periods is better, it is also safe for wheat, and the effect will be poor if the time is late. Acidic wheat herbicides can not be used at the same time with uremia, and urea should not be used with Bordeaux liquid at the same time. In order to ensure that the effect of weeding is not affected, urea can be applied at intervals of about 7-10 days after herbicides are given to wheat.

Time for wheat to hit with herbicide

The main results are as follows: 1. The suitable time for wheat to fight herbicides is the tillering stage of wheat before winter and the early stage of wheat jointing in the second year. The control effect of herbicides in these two periods is better, and it is safe for wheat, and the effect will be worse if the time is late. Among them, the earlier the herbicide is hit, the better the herbicide is, and it is better to use tribenuron before getting up after the wheat turns green to avoid drug damage to the next crop.

2. To apply herbicides to wheat, it is necessary to master not only the time, but also the temperature and humidity when the herbicide is administered. It is suitable to apply the herbicide when the average temperature is more than 6 ℃, and the control effect is better. In general, the herbicide such as benzenesulfuron is sensitive to temperature, and it will have a better control effect only after 15-20 days or even 1 month under the condition of low temperature.

3. At the same time, herbicides need to be used in sunny days and slightly higher temperatures, generally at 10:00 or 3 p.m., if the land is dry, it is necessary to increase water consumption when hitting herbicides in order to have a better control effect.

Can wheat herbicides and urea be used at the same time?

In general, acidic wheat herbicides can not be used at the same time with uremia, and urea should not be used with Bordeaux liquid at the same time. In order to ensure that the effect of weeding is not affected, urea can be applied at intervals of about 7-10 days after herbicides are given to wheat.

Third, the distribution range of wheat

1. Wheat is a kind of Gramineae plant, and is now a cereal crop widely planted all over the world. The caryopsis of wheat is one of the staple foods of human beings. Generally, it can be ground into flour to make bread, steamed bread, biscuits, noodles and other foods. After fermentation, it can be made into spirits (such as vodka), beer, alcohol, or biomass fuel. The Lianghe River Basin is one of the earliest regions in the world to cultivate wheat. China is one of the countries that grow wheat relatively early in the world.

2. East China is the central part of Shandong, Jiangsu and Anhui; Beijing, Tianjin, Henan, Hebei and Shanxi in North China; Jiangxi and Hubei in Central China; Qinghai, Ningxia, Gansu, Shaanxi and Xinjiang in the northwest; Jilin, Liaoning and Heilongjiang in the northeast; Sichuan, Chongqing and Guizhou in the southwest; Xinjiang and Inner Mongolia in the north.

3. The main components of wheat are fat, protein, crude fiber, carbohydrates, calcium, phosphorus, potassium, vitamin B1, vitamin B2 and nicotinic acid, as well as a kind of allantoin. at the same time, wheat germ is also rich in food fiber, vitamin E, and a small amount of amylase, arginine, sitosterol, lecithin, proteolytic enzyme.
