Matters needing attention in cultivating flowers with biogas slurry

Biogas slurry cultivates flowers, although the fertilizer effect is stable, the nutrients are complete, the fertility is long, and it can also treat diseases and insect pests. However, you need to pay attention to the following:

(1) the biogas residue must be fully mature, and the biogas residue can be stored in a barrel for 20-30 days before use.

(2) the biogas slurry should be open for 2-3 hours before topdressing and foliar spraying.

(3) when planting potted flowers with biogas liquid, the dosage should be calculated and excessive fertilization should be avoided. If the old leaves fall after fertilization, the concentration is on the high side, they should be hydrolyzed or changed soil in time; if the edges of the tender leaves fall off in the form of water stains, which is water and fertilizer poisoning, they should immediately take off the basin and change the soil, pruning and shade maintenance.
