The thorn-free cucumber is fertilized, and the organic fertilizer is applied, and the application of NPK fertilizer is combined. The addition of molybdenum fertilizer can increase the vitamin content of the fruit and reduce the nitrate and nitrite content. The production of 1000 kg of thorn-free cucumber requires 2.6 kg of pure nitrogen, 1.4 kg of phosphorus pentoxide, and 3.5 kg of potassium oxide. The amount of fertilizer required in the final period accounts for more than 80% of the total fertilizer requirement. Before planting, apply 5,000 kg of organic fertilizer per acre, 250 kg of bio-organic compound fertilizer, 60 kg of urea, 30-40 kg of superphosphate, and 50 kg of potassium sulfate. The first top dressing was carried out at the beginning of the melon, and the pure nitrogen was applied 3 to 4 kg per mu and the potassium oxide was 4 to 6 kg. In the early stage of the melon, the second topdressing was carried out, and 3 to 4 kg of pure nitrogen per acre and 5 to 6 kg of potassium oxide were applied. In the middle of the melon, the third top dressing is carried out, and each of the acres is applied with 3 to 4 kg of pure nitrogen and 5 to 6 kg of potassium oxide. Spray 0.02-0.05% ammonium molybdate during the fruiting period.
