The sesame grows most rapidly in the flowering and seedling stage. At this time, vegetative growth and growth and development go hand in hand, and the absorbed nutrients account for 70% to 80% of the entire growth period. As the application of nitrogen at the end of the seedlings is prolonged and high seedlings are formed, only part of the nitrogen fertilizer is generally used as the base fertilizer. In order to meet the needs of the growth and development of plants in the middle and later stages, so that sesame flowering vigorous growth, accumulation of more photosynthetic products, increase the number of calyx, stable long-term is not premature aging, so that the grain is full and full, must be top dressing. Sesame top dressing must master the top dressing period and methods. With regard to the top-dressing period, the masses saw the saying that seedlings were fertilized and fertilized. In the case of poor seedlings or large differences in seedling size, a small amount of top-up seedlings or partial application may be used to dilute the decomposed human excreta or urea. “Seedlings with large sesame seedlings†is the time when flower buds differentiate. At this time, the top dressing effect is best. Topdressing is dominated by nitrogen fertilizer, supplemented by phosphorus and potassium fertilizers. When sesame enters the flowering stage, lateral roots have begun to form in large numbers. The absorption capacity of the roots has increased, the growth rate of plants has been accelerated, and the requirement for nutrients has also increased significantly. It is necessary to re-apply flowering fertilizers in a timely manner to make it more convenient for chemical fertilizers. It is also possible to use decomposed cakes and manures. , Feifei and so on. Drilling should be carried out in the middle of the row, or in the middle of a row. Apply about 10 centimeters into the soil to absorb the roots, cover the soil after application, and remove field weeds. In the case of sowing, in addition to cooked cake fertilizer or granular urea can be mixed with soil application, then cultivator soil cultivating, all kinds of other fertilizers should be opened point application, avoid application, such as ammonium sulfate powder, nitric acid Ammonium is apt to deliquescence and easily adheres to the velvet hair of sesame leaves, causing burning seedlings. When the weather is dry, irrigation can be performed after application to fully realize the fertilizer effect.
