Weeding is a very important management task in crop cultivation. Weeds not only compete with crops for water, nutrients, and light, but also easily become vectors for the spread of diseases and pests. If the weeding is not done in a timely manner or the method is improper, it may result in reduced yield, and in severe cases, it may lead to no harvest per grain. Friends who lack planting experience often encounter a problem: how can we achieve efficient grass control? Today, I am here to share with you some practical weed control techniques, hoping to help you.
Common Misconceptions in Grass Control during Planting
During the process of weeding, many people may make the following mistakes:
Excessive reliance on chemical herbicides, improper use leading to pesticide damage, and even affecting soil health.
Neglecting the growth cycle of weeds has missed the optimal time for prevention and control.
It is believed that manual weeding is thorough, but it is inefficient and prone to accidental damage to crops.
These misconceptions often lead to an increase in the cost of farmland management and a decrease in crop yield and quality. Therefore, scientific grass control is an indispensable part of the planting process.
Key Techniques for Efficient Grass Control
1、 Choose suitable herbicides and master the correct dosage
Chemical herbicides are currently one of the most convenient and effective methods for weed control, but improper use can lead to serious consequences.
Remember: When using herbicides, be sure to strictly follow the instructions. Excessive use can easily lead to pesticide damage, causing weeds to “burn to death”, but crops may also exhibit “vigorous growth” or “yellowing”. Insufficient dosage may result in incomplete grass control and increase later costs.
2、 Reasonably plan sowing time and seize the opportunity of weed growth
The growth cycle of weeds is closely related to crops, and it is crucial to know how to seize the opportunity. Crops planted later in time, such as soybeans or peanuts, are susceptible to weed infestation. You can avoid the high incidence period of weeds by adjusting the sowing time. For example:
When planting corn in spring, it is recommended to clear the weeds in the field in advance and perform shallow plowing to “suffocate” the weeds in the soil.
For winter wheat, glyphosate can be sprayed before sowing to ensure fewer and weaker weeds in the later stages.
Therefore, arranging planting time reasonably is one of the important strategies to reduce weed interference.
3、 Use coverage measures to directly block weed growth
Plastic film mulching is a widely promoted grass control measure in recent years. Especially when planting economic crops such as fruits and vegetables, plastic film can block sunlight from reaching the soil surface, thereby inhibiting the germination and growth of weeds. At the same time, covering with plastic film can also maintain soil moisture and temperature, promoting crop root development.
Attention: Remember not to use inferior plastic film, as it is easy to break and difficult to degrade. Improper cleaning can also cause environmental pollution.
4、 Combining manual weeding with effective field management
Although mechanization and chemical weed control technologies continue to advance, manual weed control remains an important part of field management, especially in areas where it is difficult to use pesticides, such as embankments and corners. Although manual weeding is time-consuming and laborious, it can accurately remove some deep rooted weeds such as dogweed and field roundflower.
Specific suggestions:
During the seedling stage of crops, cooperate with manual weeding to avoid competition between weeds and crops for glory and fertilizer.
Manually clean the field embankments 2-3 times a year to prevent the spread of weed seeds.
6、 Pay attention to the prevention and control of pests and diseases, and prevent ‘grass borne insects’
Weeds not only compete with crops for resources, but may also become habitats for pests and diseases. For example, fire dragon disease is often spread by weeds, especially in humid environments, where excessive weeds can accelerate the spread of the disease. So, while controlling grass, we should also pay attention to the comprehensive prevention and control of pests and diseases.
Therefore, weed control is not only about weeding, but also an important part of pest and disease prevention and control.
Summary and Practical Suggestions
Efficient weed control is a key link in improving crop yield and quality, which not only reduces competition from weeds but also avoids the spread of pests and diseases. By selecting suitable herbicides, arranging sowing time reasonably, using covering measures, implementing crop rotation, and combining manual weeding, you are sure to achieve scientific and efficient management of weeds in the field.
Finally, I would like to remind everyone that grass control is a long-term task and must not be relaxed. I hope the experiences shared today can help you make your farmland more productive and bountiful.
