Special compound fertilizer for vegetables and preparation method thereof

Abstract

The invention discloses a special compound fertilizer for vegetables. The special compound fertilizer is prepared from the following raw materials in parts by weight: 3 to 6 parts of ferrous sulfate, 1 to 2 parts of borax, 42 to 55 parts of goat manure, 5 to 6 parts of bacillus subtilis, 20 to 30 parts of distiller grains, 22 to 28 parts of potato skin, 25 to 33 parts of sugarcane waste, 12 to 18 parts of walnut skin, 2 to 3 parts of bacillus pumilus, 6 to 9 parts of microzyme, 5 to 7 parts of trichoderma and 26 to 35 parts of cow dung. A method for preparing the special compound fertilizer for vegetables comprises the following steps: a, heating the potato skin, the sugarcane waste, the distiller grains and the walnut skin to 120 DEG C, preserving heat for half an hour, and naturally cooling the potato skin, the sugarcane waste, the distiller grains and the walnut skin to 40 DEG C; b, adding the bacillus subtilis, the bacillus pumilus, the microzyme and the trichoderma into the mixture obtained in the step a, and sealing and preserving the mixture for 8 to 11 days; c, adding the goat manure and the cow dung into the mixture obtained in the step b, uniformly stirring the mixture, and preserving the mixture for 4 to 6 days; d, adding the ferrous sulfate and the borax into the mixture obtained in the step b, uniformly stirring, naturally air-drying and grinding the mixture.

Description

technical field [0001] The invention belongs to the technical field of agricultural chemical fertilizers, and in particular relates to a special compound fertilizer for vegetables and a preparation method thereof. Background technique [0002] There are many types of fertilizers with different effects.

Some chemical fertilizers can improve the quality and yield of vegetables, while some fertilizers will affect the quality and yield of vegetables after application. Although some chemical fertilizers can increase the yield when applied to vegetables, they will cause toxin pollution to vegetables, causing food consumption. poisoned

[0003] Ammonium nitrate and other nitrate nitrogen fertilizers are generally not suitable for application to vegetables. After nitrate nitrogen fertilizers are applied to vegetable fields, the nitrate content in vegetables will double. Nitrate is easily reduced to nitrite in the human body. Nitrite is A carcinogen that is extremely harmful to the human body

Ammonium chloride, potassium chloride and other chloride-containing fertilizers should not be applied to tomatoes, potatoes, sweet potatoes and other chlorine-containing fertilizers. After decomposition in the soil, ammonium or potassium ions will be absorbed by the soil and absorbed by vegetables. When the concentration reaches a certain level, it will Toxic to the root system of vegetables, serious will cause the death of vegetables
