Abstract

The invention discloses slow-release compound fertilizer. The slow-release compound fertilizer comprises the following raw materials in parts by weight: 10-20 parts of waste glass, 15-25 parts of plant straw, 15-30 parts of animal waste, 10-20 parts of edible mushroom residue, 8-13 parts of urea, 4-6 parts of phosphorus pentoxide, 6-8 parts of potassium oxide, 10-15 parts of humic acid, 8-17 parts of lignin, 5-10 parts of bone meal, 0-0.5 part of starch or derivatives thereof, 0.4-0.7 part of cellulose or derivatives thereof and 6-12 parts of granulating adhesives. The slow-release compound fertilizer can be applied to all soil types and crops, is capable of improving the soil structure, improving water retention capacity and fertilizer retention capacity of the soil and preventing and treating soil hardening, and especially has a good effect on improving saline-alkali soil.

Description

technical field [0001] The invention belongs to the technical field of compound fertilizers, and in particular relates to a slow-release compound fertilizer and a preparation method thereof. Background technique [0002] China's arable land accounts for 7% of the world's total, but uses about 35% of the world's chemical fertilizers. The amount of fertilizers ranks first in the world, and the low utilization rate of chemical fertilizers is the main problem. Nitrogen fertilizers are easily lost after being applied to the soil. The ways of loss include leaching, gas loss and fixation. The utilization rate of nitrogen fertilizer is only about 30%, and a large amount of losses. China loses 12-14 million tons of nitrogen fertilizer through leaching and volatilization every year, causing huge waste. Potassium fertilizer can also be lost through leaching and runoff in the soil, and its utilization rate is slightly higher, only about 35%. Fertilizer loss not only causes waste, but ...
