It is necessary to master the technology of "ten changes" in order to achieve stable and high yield of sesame.

1. Change continuous cropping to rotation. There are many sesame diseases, and most of the germs are soil-borne, so it is not suitable for continuous cropping, but should be rotated after an interval of more than 2 years.

2. Leveling is used as a high border. Sesame is not resistant to stains, and high border drainage is good, which is conducive to the growth of sesame. The standard of high border: the width of the border is 140 cm, the width of the furrow is 30 cm, and the depth of the groove is 15-20 cm. In addition, when it rains continuously, it is necessary to clear the trench and drain in time to prevent waterlogging and waterlogging.

3. Change the rain late sowing to artificial soil moisture early sowing. Sesame likes temperature, such as low temperature in the later stage of growth, weakening of photosynthesis, long yellow shoot, low grain chaff, low yield and poor quality. Therefore, after the wheat harvest, we should sow the soil in time and strive to sow as early as possible.

4. Change the single broadcast method to "double insurance" broadcasting method. First sow the seeds of 3DB 5, then sow the seeds of the remaining 2max 5, and then sow the whole seedling in one row.

5. Change the secret to be reasonable. It is suitable to plant 1-12000 plants per mu for single-plant sesame and about 8000 plants per mu for branched sesame.

6. To cure only insects into diseases and insects at the same time. The traditional way is to only control aphids and diamondback moths, but not diseases. There are many diseases of sesame, such as stem point blight, green blight, root rot and so on, especially stem point blight, Rain Water for many years, serious harm, reduced yield or even no harvest. If carbendazim can be sprayed once at seedling stage, early flowering stage and full flowering stage, the control effect is good and the yield is obvious.

7. Change from non-topdressing to topdressing. In Huaibei region, when sowing, 7-8 kg ternary compound fertilizer is applied, and then no more fertilizer is applied, while sesame enters the growth period after the early flowering stage, which is the peak period of fertilizer demand, at this time, 7-8 kg urea per mu is needed, and the effect of increasing yield is obvious.

8. Change from beating leaves to not beating leaves. Such as cutting leaves, sesame photosynthates are bound to be reduced, resulting in poor quality and low yield. Therefore, it is absolutely impossible to beat leaves.

9. Change from the top to the top. The top of the sesame should be hit at the end of the flowering stage to save nutrients, make the sesame seeds full and improve the yield and quality.

10. Change the stuffy pile to dry in time. Stuffy pile is easy to heat, so that sesame seeds are not white or bright, or even gray, reducing oil content. Small handfuls should be tied up after harvest and dried and threshed in time.
