What should we pay attention to in order to grow sesame seeds with high yield? Please introduce the following key points for high yield of sesame seeds: after ploughing, weeding, weeding, shallow hoeing and loosening soil and weeding, when the seedling height is 5 cm, the second intermediate ploughing should be carried out, and then two times of mid-ploughing should be carried out according to the soil conditions and seedling conditions. in order to achieve loose soil, good air permeability and create favorable conditions for root activity. When ploughing, we should be careful not to hoe too deep, so as not to hurt the roots. Promote the robust growth of sesame seedlings and lay the foundation for high yield. Cultivating soil to prevent lodging is the great enemy of sesame production, which has a great impact on the yield, which is generally reduced by 40% and 80%. To prevent lodging, one is to cultivate the soil. when the sesame seedlings grow to about 25mur30cm, they should cultivate the soil and choke the roots to resist wind and prevent toppling. Second, spraying paclobutrazol at the true leaf stage of sesame 2Mel 3 inhibits the vegetative growth at seedling stage, promotes root development, increases and deepens the root system, reduces leg height and knot position, avoids top weight and foot weight, and prevents lodging. Third, about 15 days after the first flowering of sesame, spraying protamine can inhibit upper ineffective flowering and capsule formation, control tip growth, reduce upper ineffective capsule competition for plant nutrients, and make plant growth healthy. Prevent lodging. Topdressing sesame at flowering stage grows most rapidly at flowering and capsule stage, when vegetative growth and reproductive growth go hand in hand, absorbing the most nutrients, accounting for about 60% of the whole growth period, and urea 1012 kg per mu should be applied at the early flowering stage. Spray 0.3% potassium dihydrogen phosphate solution on the leaves at full flowering stage to make sesame seeds grow vigorously and accumulate more photosynthates. Increase the number of flower capsules, early senescence in the stable part in the later stage, and the grain is full and full. Topping is a simple and effective measure to increase production, which can increase production by 10%, 15%, inhibit ineffective growth, regulate and balance vegetative growth and reproductive growth, make the upper capsule grain full, increase 1000-grain weight, and increase yield. Generally, topping is carried out 35 days before the sesame harvest to ensure that the upper capsule has about 35 days of filling and ripening time. The method of topping is to choose a sunny day to remove the top of the plant by hand about 2 cm. Ensure the supply of nutrients to the capsule and obtain high yield.
