The time and method of topping sesame

(agricultural Wealth net) Spring sesame will age naturally in the later stage, and the top 1 to 2 cm will be knocked off at the end of the sesame flower, which can reduce the yellow tip. The suitable time for precocious summer sesame and autumn sesame topping is determined according to local air temperature conditions. The early summer sesame topped 25 to 30 days before the normal maturity, that is, the topping period, and the suitable period for late sesame topping should be about 20 days after the first flowering; if the cultivation method of high density early topping is used, it should be topped 10 to 15 days after the first flowering. Autumn sesame topped 15 to 20 days after the first flowering. According to the temperature conditions at that time and the growth strength of sesame, topping can be appropriately advanced or postponed. Hit the top to remove the top 2 to 3 cm long.
