Abstract

Special fertilizer for scallion belongs to the technology field of fertilizer production. The special fertilizer for scallion, through adjusting ratio of nitrogen, phosphor and potassium, solves the harms brought by continuous cropping, improves the disease-prevention and disease-resistance ability of scallion, and increases the production of scallion. The special fertilizer for scallion is a compound fertilizer, and comprises following components in parts by weight: 275 to 305 parts of urea, 245 to 275 parts of thiamine, 100 to 130 parts of monoammonium, 320 to 350 parts of potassium chloride, and 0.5 to 2 parts of additive, wherein the weight percentage of nitrogen, phosphor, and potassium is 20:5:20. The special fertilizer for scallion can be widely applied to the field of scallion plantation.

Description

technical field [0001] The special fertilizer for scallions of the invention belongs to the technical field of fertilizer production. Background technique [0002] There are many seedlings and transplants in the green onion producing areas in northern China. The main production areas in the middle and lower reaches of the Yellow River are mostly sown in autumn, but it is necessary to strictly control the seedlings to no more than 3 leaves before winter; the south of the Yellow River is mostly spring sown, and sowing should be done when the local temperature reaches 7°C. Scallions are suitable for cultivation in loam soils with a pH of 6.5-7.5. Seedlings require loose fertilizer and sufficient bottom moisture. During the emergence stage, topsoil compaction should be prevented, and topdressing should be done once when the seedlings begin to grow rapidly, and the soil moisture should be controlled 10-15 days before planting to prevent excessive growth and lodging. Planting f...
