Abstract

The invention discloses slow-release fertilizer for lettuce cultivation and a preparation method thereof. The slow-release fertilizer is prepared from 40-50 parts by weight of rapeseed cake, 40-50 parts by weight of straws, 30-40 parts by weight of peanut shell, 20-25 parts by weight of sheep feces, 8-13 parts by weight of garlic powder, 10-15 parts by weight of earthworm powder, 10-15 parts by weight of vermiculite powder, 10-15 parts by weight of plant ash, 1-2 parts by weight of magnesium sulfate, 5-8 parts by weight of borax, 1-2 parts by weight of calcium chloride, 30-40 parts by weight of bentonite, 3-4 parts by weight of cellulose nanocrystals, 30-35 parts by weight of vegetable oil, 3-4 parts by weight of gamma-oryzanol, 2-3 parts by weight of beta-sitosterol, 15-20 parts by weightof talc powder and 0.1-0.2 parts by weight of an EM-bacteria agent. The coating material used in the slow-release fertilizer is easily degraded in the soil and can reduce pollution. The slow-releasefertilizer can improve the air permeability and water retention effects of the soil and provide a good environment for the growth of the lettuce.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a slow-release fertilizer for lettuce planting and a preparation method thereof. Background technique [0002] As the global population grows, so does the demand for food. Fertilizers play an important role in increasing food production and income. However, most of the nutrients in fertilizers are not used by plants, but are discharged into water, soil, and the atmosphere through volatilization, runoff, infiltration, etc., which not only causes economic losses, but also causes environmental pollution. Nutritization, groundwater pollution, increase in nitrogen oxides and greenhouse gases, decline in soil quality, reduction in arable land, and a series of problems. Therefore, improving the utilization rate of fertilizers and reducing the harm of fertilizers to the environment has become an urgent problem. The development of slow / controlled release fertilizers adapted to crop growth is...
