The role of timely topping of sesame

(agricultural Wealth net) "Sesame blossoms higher and higher" is the embodiment of top growth advantage. In summer and autumn, this advantage can make the plant increase, grow and increase capsule in the early stage, but in the later stage, with the advent of low temperature, the advantage becomes a disadvantage. When the lowest temperature is lower than 18 ℃, the flower of sesame is ineffective, but it still grows under apical dominance and consumes nutrients. At this time, topping can reduce ineffective consumption, concentrate nutrients on capsules and grains, and increase 1000-grain weight. Generally, topping can increase production by more than 10%.
