How to Grow Black Sesame? Latest Planting Methods and Timing Explained
Black sesame is a very popular crop in China. It not only has very high edible value, but is also a major oil crop. At present, the planting area of black sesame in China is still quite large, and the market demand for black sesame is growing, so the demand for black sesame yields is also increasing. So how should black sesame be grown? And when should it be planted? Let's take a look together below!
1. Planting Time
The sowing time for black sesame is actually the same as for sesame. When sowing, we should control the sowing time according to the variety being grown and the timing. For example, when growing summer sesame, sowing should be chosen in May to June each year. If it is autumn sesame, then sowing should be carried out in early July. If the heat is good enough, it can be appropriately postponed to late July. Whether growing summer sesame or autumn sesame, it is necessary to ensure relatively high temperatures and high evaporation. Then the land preparation must be done well; maintaining soil moisture is the key to ensuring full emergence of black sesame.
2. Planting Methods
Site Selection and Seed Selection
When growing black sesame, the first step is to choose a good planting plot. The planting plot for black sesame should be chosen on high ground with good drainage and irrigation. Then do the land preparation well; during land preparation, apply sufficient base fertilizer together with the fertilization work, then level and rake the soil finely, and prepare for sowing. Before sowing, do the seed soaking work well, and carry out germination promotion and disinfection of the seeds. Put the seeds into a solution of carbendazim mixed with water, and stir it evenly. If it is summer sesame, then sow appropriately early, but the planting must not be too dense, so as to ensure the normal growth of black sesame.
Water and Fertilizer Management
When growing black sesame, the watering work must be done well. When planting, dig the bed furrows and surrounding furrows well to improve the drainage and irrigation capacity of the field. Then, according to the growth of the black sesame seedlings and the soil moisture, do the watering work well. When growing black sesame, it is necessary both to guard against drought and to prevent waterlogging, so watering should not be excessive either, and if water accumulates, it should be drained in time. Then do the topdressing work well. During the growing period, if the seedlings are sparse and their growth is weak, then appropriately apply urea as topdressing. In ordinary topdressing, the fertilizers are mainly urea and phosphorus and potassium fertilizers, to provide sufficient nutrients for the growth of black sesame.
Field Management
When growing black sesame, to increase the yield, the topping work needs to be done well. For summer sesame, top when two pairs of true leaves are retained, then keep about 3 cm of stem nodes above the leaves. After topping, to prevent the new branches from suffering fertilizer deficiency, appropriately apply a quick-acting fertilizer once. Then do the pest and disease control work well, such as for fusarium wilt, bacterial wilt, aphids, and so on. Pests and diseases can cause reduced black sesame yields in mild cases, and in severe cases can cause the plants to die. Both yield and quality will be greatly affected. Finally, control the harvest time well; harvest should be carried out when the capsules about 5 cm on the lower part of the plant crack open, and harvesting should not be too early or too late.
The above is a brief introduction to the planting methods and timing of black sesame. That is all for today's introduction. This article is for reference only, and we hope it can help everyone!
