High yield field management of sesame

Sesame is an annual erect herb of Sesame family. It has a wide range of distribution in the tropics of China, which can not only be used for food, but also a major oil crop. Its economic value is very high, when planting sesame, field management is the key to ensure its high yield. So how to manage planting sesame seeds? The following editor brings you the field management technology of sesame, let's have a look!

1. The seedlings are fixed

After sowing sesame seeds, it is necessary to do a good job of management, soil mulching, film mulching and watering to promote seed germination. After the seedlings are unearthed, when they grow to about 1 or 3 true leaves, it is necessary to do a good job of interseedling work to avoid the phenomenon of wasted seedlings. It is usually necessary to interplant seedlings twice or so, and the time of interseedling should be early. If it is too late, it will reduce the field permeability, cause each other to seize sunlight and nutrients, and affect the yield. Then it is necessary to fix the seedlings when there are 4-5 true leaves, maintain a certain planting density, and provide sufficient growth space for healthy seedlings. Finally, at the mouth of the lack of seedlings, we should pay attention to make up the healthy seedlings with the same growth to ensure the whole seedlings.

2. Ploughing and weeding

Intertillage weeding is very important to the growth of sesame. Especially in the sesame seedling stage, because the growth ability of sesame seedlings is relatively weak. If weeds are not weeded in time, weeds will rob the nutrition and moisture of sesame, seriously affecting the growth of sesame. Reasonable intertillage can not only achieve the effect of weeding, but also improve soil permeability and drainage and irrigation capacity. Improve soil structure, promote nutrient absorption, prevent lodging of sesame, and enhance the growth ability of sesame. The sesame seeds should be ploughed at least 3 times between the seedling stage and the first flowering stage until the middle tillage was stopped after the row was closed.

3. Water and fertilizer management

Water nutrition is an indispensable nutrient in the growth process of sesame. Sesame is very sensitive to the change of soil water content in its growth. it not only has a certain demand for water, but also does not resist waterlogging, so we should control the amount and frequency of watering according to soil water content and weather. Avoid too little water affecting the growth of sesame, too much water leads to root retting of sesame causing diseases and insect pests. Then we should not only apply sufficient base fertilizer before planting, but also do a good job of topdressing in the important growth period of sesame, such as flowering and fruiting stage and returning to green stage, so as to meet the nutritional needs of sesame growth. Attention should be paid to controlling the dosage to prevent the occurrence of fertilizer damage, which is counterproductive.

4. Pest control

Diseases and insect pests have the greatest impact on the yield of sesame. Therefore, when we plant, we must pay attention to the prevention and control of diseases and insect pests. Sesame common diseases and insect pests are blight, root rot and small land tiger and so on. We should do a good job in the prevention of these diseases and insect pests and strengthen management. To control the amount of water and fertilizer, while meeting the demand, it is necessary to prevent waterlogging, fertilizer damage and so on. Then we often observe the growth of sesame, and when abnormal conditions are found, we should deal with them in time to avoid expanding the damaged area and affecting the planting efficiency.

The above is a brief introduction to the high-yield field management of sesame. The yield of sesame is directly related to the planting benefit, so if you want to increase the yield, field management must be done well to improve the growth ability of sesame to avoid some unnecessary losses. That's all for today's introduction. This article is for reference only. I hope it can help you all.
