Sesame planting conditions

Sesame is very familiar to us, and we often see it in daily life. It is widely used in many foods. In addition, sesame is one of the important oil crops in our country, and it has a wide planting area in our country. So what conditions do you need to grow sesame seeds? Let's have a look with the editor.

1. Soil requirements

Sesame is suitable to grow in the soil conditions of loose soil, high fertility and convenient drainage and irrigation. it has strict requirements on soil, and sandy loam is the most suitable, but also suitable for slight silt and alluvial soil. However, swamp soil, saline soil and low-lying land are not suitable for planting sesame seeds, these soils are too sticky, and the soil is easy to harden or harden after drought or rain, which is not conducive to seedling emergence and leads to lack of seedlings and broken ridges in serious cases. Moreover, it will also limit the development of the root system, affect the root absorption of fertilizer and water, resulting in weak plant growth, slow growth, extremely prone to diseases and insect pests, and reduce yield and quality.

2. Moisture requirements

Generally speaking, sesame is more drought-tolerant, but the demand for water is also different in different growth stages, especially from sowing to emergence. This is because the sesame plant is small and the seedlings grow slowly. If the soil is too dry, the seedlings can not emerge normally. Even after emergence, the seedlings will grow slowly. However, there should not be too much water, too much soil moisture in the seedling stage, which can easily lead to yellowing and thinness of seedlings, and in serious cases, it will also cause rotten seeds, rotten roots and dead seedlings. And fear of soiling is a prominent feature of sesame, general soil water content of more than 90%, it will cause waterlogging damage, resulting in rotten roots, stems and leaves wilting, dead seedlings.

3. Temperature requirement

Sesame is a temperature-loving plant, which needs accumulated temperature of 2500-3000 degrees during the whole growth period, and the lowest temperature during seed germination is 12 degrees. For its normal emergence, it needs more than 16 degrees, but above 40 degrees, seeds can not germinate normally. The suitable temperature for its growth is 20-24 degrees, lower than 5 degrees, the seedlings will grow only, and the roots will rot due to frost injury. In addition, the low temperature has a great effect on its flowering. When the temperature is lower than 20 degrees, the number of flowers will be significantly reduced. In the fruiting stage, if the temperature is high, it has more nutrients and high oil content, on the contrary, the temperature is low, which is disadvantageous to the accumulation of oil.

4. Lighting requirements

Sesame is a short-day plant, which needs sufficient light during the whole growth period, which can significantly increase the ground temperature and make its seedling emergence fast and neatly. Sesame flowering and capsule period is long, sufficient light conditions can enhance its photosynthesis, the accumulation of excellent nutrients, meet its flowering needs, can make the capsule full, which is conducive to the formation of oil. In general, in areas where the light is insufficient and rainy, its yield is generally low, which shows the importance of light for sesame.
