Sesame planting: how to fertilize summer sesame seeds?

How to fertilize summer sesame? Please guide the effective fertilization methods of sesame in order to achieve higher yield of summer sesame, it is necessary to apply nitrogen, phosphorus and potassium fertilizer timely and skillfully. When fertilizing, we should pay attention to grasp the principles of stability, accuracy and ruthlessness. Detailed references are as follows: a stable, that is, fertilization at the seedling stage should be stable. The growth of summer sesame seedlings is slow, and the ability of roots to absorb nutrients is weak. If the basal fertilizer is insufficient, the seedlings will be thin, so we should apply the fertilizer as soon as possible, but the amount of fertilizer should be small, otherwise it is easy to cause tall seedlings. The second criterion, that is, topdressing in the bud stage should be accurate. The growth rate of summer sesame is obviously accelerated from budding to early flowering stage. at this time, topdressing can promote flower bud differentiation and increase the number of capsules. Three ruthlessness, that is, it is necessary to be ruthless in the flowering period. From flowering to maturity, summer sesame seeds bloom, form capsules and mature, and the demand for fertilizer increases sharply. Topdressing in this period can not only reduce the tip and blighted grains of summer sesame, but also increase the weight of 1000 grains. It is generally required that topdressing at full flowering stage should be early and should be applied in two stages: 2 kg of pure nitrogen per mu 10 days after the first flowering and 3 kg of pure nitrogen per mu 10 days after capsule formation. In order to meet the large demand for phosphorus and potash fertilizer at full bloom, 2 kg of phosphate fertilizer, 1 kg of potassium fertilizer and 50 kg of water can be used per mu, and the clear liquid can be sprayed after mixing.
