How to manage sesame at the seedling stage? Latest management priorities explained in detail

Sesame planting is very common in our country, as a food crop that can be both eaten and used for oil pressing. Sesame is still very popular among many people in our country. When planting sesame, if you want to improve the yield and quality of sesame, then management work is very important. We need to manage according to the growth stage of sesame. So how should sesame be managed at the seedling stage? Below, the editor will briefly introduce it to everyone, let's take a look together!

1. Soil management

During the sowing season, sesame often encounters rain after sowing. If it rains after sowing, the soil will become compacted as a result. The lower soil layer will also become short of oxygen due to being too wet, causing the seeds to be unable to germinate and emergence to be blocked. As a result, sesame will show a serious shortage of seedlings, causing a sharp drop in yield, or even a total loss. Therefore, the soil compaction must be broken in time to ensure that the seedlings can emerge normally and achieve full and uniform seedlings. Generally, when the soil turns white after rain, promptly shallow hoe the compacted soil or lightly harrow it horizontally to break the hard soil crust and help the seedlings emerge.

2. Checking seedlings and replanting

Under suitable planting conditions, summer sesame will emerge 5 days after sowing, autumn sesame 3 days after sowing, and spring sesame about one week after sowing. If the emergence time is too late or incomplete, the cause should be investigated in time and corresponding measures taken. For missing seedling holes, reseed in time. If the missing seedlings are scattered, move seedlings to replant. When replanting, first dig the planting holes at the missing seedling spots while controlling the plant and row spacing well. If the soil moisture is poor, water appropriately, then select nearby robustly growing seedlings, replant them with soil into the planting holes, then gently firm the surrounding soil, and cover with a layer of fine soil to prevent the soil from cracking and reducing moisture preservation capacity.

3. Thinning and final singling of seedlings

During the sesame seedling stage, we also need to do a good job of thinning and final singling of seedlings. When sesame grows two leaves, the first thinning can begin. Keep the robustly growing seedlings and remove some weak seedlings. Then when 2-3 pairs of leaves have grown, thin again. The final singling work is carried out when the sesame seedlings grow their fourth pair of leaves. The final singling time should not be too early, and watering should be done well before final singling. Transplanting should be carried out after rain or on a cloudy evening.

4. Intertillage and weeding

In addition, intertillage and weeding during the sesame seedling stage are also very important. We should pay attention to changes in the weather and make corresponding changes. Usually, at the time of the first thinning, intertillage can begin. Improve soil permeability and enhance the growth ability of the seedlings. However, because the root system of the seedlings is not deep at this time, shallow cultivation should be the main method. At the time of the second thinning, cultivate again, remove weeds in the field, prevent weeds from competing for the nutrients needed for the growth of sesame seedlings, and ensure normal seedling growth.

The above is a brief introduction to the key points of sesame seedling stage management. That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
