Sesame planting: how to fertilize summer sesame?
How to fertilize summer sesame seeds? Please introduce fertilization methods for planting summer sesame in order to achieve high yield, it is necessary to apply heavy and shallow base fertilizer, appropriate amount of seed fertilizer, re-application of flower bud fertilizer, supplementary spraying of phosphorus and potassium fertilizer, and mainly organic fertilizer, combined with phosphorus and potash fertilizer. minimize the amount of chemical fertilizer to improve the quality of sesame. The amount of fertilizer required for every 100 kg production of sesame: nitrogen fertilizer 6.24 kg 8.13 kg, phosphorus fertilizer 2.19 kg 3.28 kg, potash fertilizer 6.24 kg 10.19 kg. However, in summer sesame planting, most farmers do not apply base fertilizer, topdressing only urea or a small amount of compound fertilizer. The unreasonable application of fertilizer seriously affected the potential of sesame yield increase. At present, summer sesame has entered the middle stage of growth, and it is necessary to do a good job in fertilizer management in the middle and later stages to increase production and income. Topdressing base fertilizer for fields that do not apply base fertilizer, it is necessary to seize the time to top fertilizer to prevent de-fertilization. For high-yield fields, 10 kg of high-quality potassium sulfate compound fertilizer is applied per mu, and the depth of shallow burial is 4-6 cm; for medium-and low-yield fields, 10 kg of high-quality potassium sulfate compound fertilizer and 5 kg of urea are applied per mu. Re-application of flower bud fertilizer should be re-applied to the fields where base fertilizer has been applied. For single-culm sesame, when flower bud fertilizer is applied from bud to early flowering stage, those with weak soil fertility or poor growth should be applied early, while branch sesame should be applied when branches appear. Generally, 5kg of urea is applied per mu, 5kg of high quality potassium sulfate compound fertilizer is added, or 10kg of high quality potassium sulfate compound fertilizer is applied per mu. Supplementary spraying of phosphorus and potassium fertilizer in the early flowering stage of summer sesame, 50 kg of potassium dihydrogen phosphate solution of 0.3% to 0.4% per mu was sprayed evenly once every 5 to 6 days for 2 times. At the same time, borax, ammonium molybdate solution or zinc sulfate solution can be sprayed at intervals of 50 kg per mu, and the yield can be increased by more than 10% per mu. The general concentration of borax spraying is 0.2%, ammonium molybdate is 0.05%, and zinc sulfate is 0.2%.
