Weeding methods and matters needing attention of soybean

Soybean as a widely planted crop in China, weeds often appear in the soybean field, which will compete with soybean for water and fertilizer, which is not conducive to yield and quality, so weeding should be done well, but weeding should also be paid attention to to avoid drug damage to soybean. So what are the precautions for soybean weeding? Let's get to know it.

1. Weeding methods of soybean

Perennial weeds such as spinach, borage and Reed are common weeds in soybean fields. they have the characteristics of strong rhizome reproduction, deep root system and strong drug resistance, so it is necessary to increase the dosage when weeding with chemicals, but it is also easy to cause drug damage and affect the yield. Therefore, in view of this situation, glyphosate solution can be used to control these perennial malignant weeds, and the effect is better. Weeding can also be carried out before seedlings and closed treatment can be carried out before arching the soil after sowing to remove weeds.

II. Matters needing attention in weeding

1. Strict standard and scientific mixed medicine solution

In the preparation of pesticides, the pesticide should be added to the appliance according to the standard, and then the powder pesticide should be diluted into a mother solution with a little water, and then the appliance should be added with quantitative water, and the appliance should not be filled with water first and then the liquid should be added. to prevent uneven spraying and poor efficacy due to insufficient dissolution of water and medicine.

2. Adjust measures to local conditions and select drugs accurately.

The herbicide should be pre-bud herbicide, which is a good herbicide because of its short residual period and safety for the next crop. After sowing, chemical weeding before seedling can not be selected, such as kekuole, fine grass, 2mai 4mer D and so on.

3. Timely spraying

Spray immediately after sowing to prevent drought and other weather from affecting the efficacy, but it should not be too late. The right thing to do is to spray 3-4 days after sowing in plots with better soil moisture, and finish spraying 4-5 days before emergence in plots with poor soil moisture. Therefore, before weeding at the seedling stage, we must ensure that there is sufficient water and ensure that the amount of water applied per mu is 30-35 kg. At the same time, depending on soil moisture and climatic conditions, you can spray clean water at any time, 20-30kg per mu to improve the efficacy.
