The thorny cucumber was hi-fertilized and the organic nitrogen fertilizer was applied at the same time as the application of NPK fertilizer. Increasing molybdenum fertilizer can increase vitamin content in fruits and reduce nitrate and nitrite content.
The production of 1000 kg of barbed cucumber requires 2.6 kg of pure nitrogen, 1.4 kg of phosphorus pentoxide, and 3.5 kg of potassium oxide, of which the required amount of fertilizer accounts for more than 80% of the total fertilizer requirement.
Before planting, 5000 kg of organic fertilizer was applied per mu, 250 kg of bioorganic compound fertilizer, 60 kg of urea, 30-40 kg of superphosphate, and 50 kg of potassium sulfate. In the early stage of fruiting, the topdressing fertilizer was applied for 1 to 3 kg of pure nitrogen per acre and 4 to 6 kg of potassium oxide. In the early stage of the harvest, the first time, the top dressing was applied with 3~4 kg pure nitrogen and 5~6 kg of potassium oxide. In the middle of the melon period, the 3rd top-dressing fertilizer was applied, with 3~4 kg of pure nitrogen per acre and 5~6 kg of potassium oxide. Spray 0.02% to 0.05% ammonium molybdate at full fruit stage.
