The flowering period of sesame seeds is a critical period for high yields. In order to obtain sufficient ears, grains and grain weights, it is necessary to strengthen field management during this period.

1, Top dressing

The flowering period of sesame seeds is a critical period for yield formation. Therefore, it is necessary to ensure sufficient nutrients and timely topdressing. About a week after flowering, combined with irrigation, apply 20kg/mu of haofangzi 15-15-15 npk fertilizer to open furrows, which is beneficial for more flowering and more fruity capsules.

2. Drought resistance and drainage

During the flowering and pod-setting period of sesame seeds, due to the high temperature season, if there is no rain for a long time, drought will also affect the growth and development of sesame seeds, causing sesame buds and young pods to fall off, resulting in an increase in sesame seeds and a serious reduction in production. Therefore, watering should be done in time in case of drought. Watering is recommended in the morning or evening and avoid flooding. If there is a lot of rain, sesame seeds are susceptible to damage, and the damage is likely to increase the number of sesame seeds. In severe cases, the sesame plants die and the seeds are not harvested. Therefore, after heavy rains, water must be drained in time to prevent waterlogging.

3. Controlling pests and diseases

The diseases that are prone to appear in the flowering period of sesame seeds mainly include stem spot blight, fusarium wilt, blight and bacterial wilt; insect pests mainly include aphids, stem borers, and cabbage caterpillars. It is suggested that farmers should pay attention to prevention and control from the seedling stage. To control aphids, imidacloprid and thiamethoxam can be used for control. For the control of hawk moths and stem borers, cypermethrin, chlorantraniliprole, emamectin benzoate, etc. can be used to prevent and control. When spraying, pay attention to spraying on flower buds and capsules. When there are many pests, spray once every 5 to 7 days.

4. Timely topping

The topping time of sesame is in the late blooming stage, generally 25-30 days before the mature blooming stage. The topping is done at one time during the blooming stage, which is beneficial to the consistency of the sesame maturity period. The topping should be carried out in the morning on a sunny day. The top tips of 3~4 cm are removed, and the old and diseased leaves in the lower part are removed at the same time.
