In order to obtain high yields of summer sesame seeds, it is necessary to apply nitrogen, phosphorus, and potassium fertilizers in a timely manner. When fertilizing, it is necessary to pay attention to the principles of stability, accuracy, and standardization. A stable, stable seedling fertilizer. Summer sesame seedling growth is slow, the ability of the root to absorb nutrients is weak, if the base fertilizer deficiency will cause thin seedlings, should be applied as soon as possible to mention seedlings fertilizer, but the amount of fertilizer to be small, otherwise it is easy to cause high foot seedlings. The second standard, that is, budding period fertilizer should be accurate. Summer sesame buds to the early flowering stage, the growth rate is significantly accelerated, at this time if timely fertilizer can promote flower bud differentiation, increase the number of scars. Sancha, that is, flowering fertilizer. Summer sesame blooms from flowering to ripening, pods, and ripening, and the demand for fertilizer increases dramatically. During this period, topdressing can both reduce the tip of yellow sesame seeds and pods, and increase grain weight. General requirements, early flowering fertilizer should be early, should be divided into two applications: 10 days after the beginning of flowering, topdressing pure nitrogen 2 ~ 3 kg per acre, 10 days after the end of acre should be topdressing pure nitrogen 3 ~ 5 kg . In order to meet the large demand for phosphorus and potassium fertilizers in the flowering period, 2 kg of phosphate fertilizer, 1 kg of potassium fertilizer and 50 kg of water can be used per acre.
