Soil sealing treatment is the first and most important part of chemical weeding in wheat fields. It can significantly reduce the number of weeds in winter wheat fields. The weeds that germinate after spring are much smaller than wheat seedlings, and are easy to be supplemented with stem and leaf treatment agents. In addition, the cost of medication and labor can be greatly reduced. In the process of soil treatment, the contact between the agent and the wheat seedling is reduced, and the possibility of drug damage is also reduced. In recent years, the effect of blocking treatment has become more important in the context of some malignant weeds that enhance the resistance of some stems and leaves to herbicides. At present, the production mainly uses isoproturon and its compounding agent for soil sealing treatment, and the medicine also has the herbicidal effect of stems and leaves. "For late sowing wheat, the soil closure before seeding is more important." Jiangsu Suoke Agrochemical Co., Ltd. Qiu Guang recently told reporters in an interview. When the late sowing wheat is planted, the temperature is generally low, and the emergence time of wheat is elongated. If the drug is used after emergence, the probability of a large temperature drop is large, and the temperature range suitable for weeding stems and leaves is narrow, so it is easy to miss the best. During the period of medication, such as the use of drugs such as isoproturon, the probability of "freezing phytotoxicity" is greater. The wheat field is closed to the soil, and some areas are used to medication immediately after sowing. According to Qiu Guang, many years of production practice has shown that it is better to delay the time of medication, and to control the herb before the needle is established. This is because the soil aggregate structure is unstable in the short-term after sowing, and it is easy to be broken. After using the soil sealing treatment agent, a strict soil layer cannot be formed, which will affect the sealing effect. It is generally recommended to use the medicine just after the wheat has been germinated and not yet unearthed. On the one hand, the soil has been solidified at this time, which is conducive to the formation of a stable soil layer; on the other hand, grass weeds have sprouted and roots, which is beneficial to absorb the drugs in the soil, improve the herbicidal effect, and play a role in joint sealing. At the same time, it can also eliminate some of the broadleaf weeds that emerged before winter. The emergence time of wheat is greatly affected by factors such as temperature and moisture. It is recommended to check the germination process of wheat in time to determine the time of drug use more reasonably. Need to be reminded that at this time, pay attention to dredge the wheat field ditch to prevent continuous rainy water accumulation; use drugs that are safe for wheat shoot growth, avoid using acetochlor-containing drugs to prevent burning buds when water is accumulated. "On the basis of selecting a good medicine, the use of sufficient water will help the drug to form a tighter soil layer in the soil, thereby improving the effect of closed weeding. Even if the soil moisture in the field is suitable, the water consumption cannot be reduced at will." Qiu Guang reminded. Generally, the water consumption per mu is about 50 kg, coarse spray. If large-scale spray machinery is used, the amount of water needs to be increased appropriately. Disclaimer: Some articles on this website are transferred from the Internet.

Late sowing wheat should pay attention to closed weeding
Affected by continuous rainy weather, rice harvesting in our province has been generally blocked recently, affecting the timely sowing of wheat, and the area of ​​late sowing wheat will be larger. The current weather is getting better, the wheat in various places will continue to enter the sowing period, and the elimination work will follow. Experts reminded that after sowing wheat, it should focus on soil sealing before the needle is established to improve the herbicidal effect, reduce the chance of "freezing phytotoxicity", and reduce the cost of medication.
