Vegetable plantation fertilizer and preparation method thereof

Abstract

The invention discloses a vegetable plantation fertilizer which is prepared from the raw materials of, by weight: 400-500 parts of sheep dung, 200-240 parts of mushroom plantation waste, 100-120 parts of rice bran, 130-150 parts of rapeseed meal, 50-60 parts of fine sand, 40-50 parts of potassium ore powder, 20-25 parts of oil refining residue, 30-40 parts of ammonium phosphate, 20-25 parts of urea, 10-12 parts of ammonium sulfate, 6-9 parts of magnesium sulfate, 6-9 parts of an EM inoculant, 10-15 parts of a soil conditioner, and proper amount of water. According to the fertilizer provided by the invention, sheep dung is adopted as a main raw material, and organic raw materials and inorganic chemical fertilizers such as mushroom plantation waste, rice bran, rapeseed meal, fine sand, potassium ore powder, oil refining residue, ammonium phosphate, urea, ammonium sulfate, and the like are used as auxiliary materials. If simply organic fertilizer is adopted, the fertilizer is rich in organics, but nutrient release is slow. If the organic fertilizer is combined with inorganic chemical fertilizers, nutrient needed by vegetables can be substantially supplemented, vegetable quality can be improved, vegetable yield can be increased, and soil can be improved.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a fertilizer for vegetable cultivation and a preparation method thereof. Background technique [0002] Vegetables are popular vegetables that are commonly eaten by people. They have large daily consumption, fast growth and short growth cycle. The vegetables supplied in the market are basically produced in fields and greenhouses, and the soil cannot be turned during the vegetable growth process. Now When basal fertilizer is applied on the vegetable ground, the utilization rate of the fertilizer is very low, resulting in fertilizer residue, soil compaction, vegetable production reduction, ecological environment damage, water eutrophication, increased production costs, and brought economic losses to farmers. Loss. More importantly, water was poisoned by eating vegetables with high toxicity and high residues, and serious food unsafe accidents occurred, which caused great harm to...

[0002] Vegetables are popular vegetables that are commonly eaten by people. They have large daily consumption, fast growth and short growth cycle. The vegetables supplied in the market are basically produced in fields and greenhouses, and the soil cannot be turned during the vegetable growth process. Now When basal fertilizer is applied on the vegetable ground, the utilization rate of the fertilizer is very low, resulting in fertilizer residue, soil compaction, vegetable production reduction, ecological environment damage, water eutrophication, increased production costs, and brought economic losses to farmers.
