The latest planting method and time of black sesame
Black sesame is a very popular crop in China. Not only has a very high edible value, but also a major oil crop. At present, the planting area of black sesame in China is still very large, and the market demand of black sesame is also increasing, so the demand for the output of black sesame is increasing. So how to grow black sesame? When is it time to plant? Let's take a look at it with the editor.
1. Planting time
The sowing time of black sesame is actually the same as that of sesame. When sowing, we should control the sowing time according to the planting variety and time. For example, when planting summer sesame seeds, you should choose to sow seeds in May-June of each year. If it is autumn sesame, it should be sown in early July. If the heat is good, it can be put off until the end of the day. Whether it is planting summer sesame or autumn sesame, it is necessary to ensure high temperature and large evaporation. Then to do a good job of soil preparation, keeping soil moisture is the key to ensure the whole black sesame seedling.
2. Planting method
Selection of land and seed
When planting black sesame seeds, you should first choose the planting plots. The planting plots of black sesame should be in the plots with high terrain and good drainage and irrigation. Then do a good job of soil preparation, soil preparation should be combined with fertilization work to apply sufficient base fertilizer, and then reduce leveling rake broken, ready to sow. Seed soaking should be done well before sowing and seed germination and disinfection should be carried out. Put the seeds into a solution in which carbendazim is mixed with water and mix them well. If it is summer sesame, then it should be sown early, but not too dense to ensure that black sesame can grow normally.
Water and fertilizer management
When planting black sesame seeds, watering should be done well. When planting, border ditches and enclosing ditches should be dug to improve the capacity of drainage and irrigation in the field. Then according to the growth of black sesame seedlings and soil moisture to do a good job of watering, planting black sesame should not only release drought but also prevent waterlogging, so watering should not be too much, if it produces stagnant water, it should be drained in time. Then to do a good job of topdressing, in the growing period, if the seedlings are sparse and the growth is weak, then urea should be applied properly. In general topdressing, urea, phosphorus and potassium fertilizer are the main fertilizers, which provide sufficient nutrition for the growth of black sesame.
Field management
When black sesame is planted, it is necessary to do a good job in topping in order to increase the yield. Summer sesame is topped when two pairs of true leaves are retained, and then the stem nodes about 3 cm above the leaves should be retained. After topping, in order to avoid de-fertilization of new branches, it is necessary to apply quick-acting fertilizer properly. Then we should do a good job in the prevention and control of diseases and insect pests, such as Fusarium wilt, bacterial wilt, aphids and so on. Light diseases and insect pests will lead to a reduction in the yield of black sesame, and heavy will lead to plant death. Both output and quality will be greatly affected. Finally, in order to control the harvest time, the harvest should be carried out when the fruit is cracked in the lower part of the plant, and it should not be harvested too early and too late.
The above is a brief introduction to the planting method and time of black sesame. That's all for today's introduction. This article is for reference only. I hope it can help you all.
