Last Updated: 2024/11/05, The amount of phosphorus uptake of rape was the highest at bolting stage, but the effect of phosphorus utilization and yield increase was the best at seedling stage. Because phosphorus can be used repeatedly in rape, the earlier the absorption period is, the greater the efficiency is. The application of phosphate fertilizer can promote the growth stage, 2-4 days earlier in seedling stage, 2-6 days in bolting stage, and 1-2 days in mature stage.

Biogas residue contains 10% Mel 20% humic acid, which can increase the activity of humic acid and improve fertilizer efficiency by using ammonia or ammonium bicarbonate solution and acidic groups in the molecular structure of humic acid to form humic acid. The method of retting biogas humic acid fertilizer is to compost the biogas dregs extracted from the biogas digester with organic waste or soil, add a layer of waste (or soil) and a layer of biogas dregs 20 cm thick to form a large round platform-shaped fertilizer heap. Then cover the surface with some soil and pat it, and compost it for 15 days to form biogas fertilizer. If calcium, magnesium, phosphate fertilizer or phosphate rock powder is added to each cubic meter of biogas dregs during composting, it will become biogas rotten phosphate fertilizer. The fertilizer is suitable to be used as base fertilizer, with an application rate of 1000 kg per mu. According to the experiment of Beijing Academy of Agricultural Sciences, biogas rot phosphate fertilizer has a significant effect on increasing the yield of wheat, corn, eggplant and green pepper, with corn increasing by 13.8% and green pepper by 15%.
