The invention relates to the field of
crop compound fertilizers, and in particular relates to a green and
disease-resistant slow release compound
fertilizer special for increasing production of peanuts. The compound
fertilizer is prepared from the following raw materials in parts by weight: 1-3 parts of waste tobacco leaves, 5-6 parts of
camphor tree leaves, 20-25 parts of a composting cattle pen
fertilizer, 12-15 parts of corn cobs, 20-22 parts of
ammonium sulfate, 4-5 parts of
zinc sulfate, 8-10 parts of
calcium sulfate, 2-3 parts of
sodium silicate, 6-8 parts of
borax, 8-10 parts of
sodium carboxymethylcellulose, 1-2 parts of
sodium lauroyl sarcosine, 15-18 parts of
lotus leaf residues, 6-8 parts of coffee residues, 0.2-0.3 part of clove leaf oil, 2-4 parts of
ferrous chloride, 1-3 parts of raw minced garlic, 1-3 parts of
gluconic acid-
delta-
lactone and 3-5 parts of an auxiliary agent. According to the green and
disease-resistant slow release compound fertilizer,
powder with active adsorption performances is prepared by using the
lotus leaf residues and the coffee residues, and the
powder is mixed with the raw materials such as
organic matter fermentation liquid, medium trace elements, the auxiliary agent and the like which are rich in
active components to achieve an effect of fixing nutrients; a modified
sodium carboxymethylcellulose slow-release film-
coating agent has good slowly-controlled fertilizer release capacities to ensure that the fertilizer effect is efficient and durable. The compound fertilizer disclosed by the invention can be used for effectively improving the
insect-resistant and
disease-resistant capacities of the peanuts, and has significant production increasing effects.
