Slow-release carrot special fertilizer capable of improving soil

Abstract

The invention discloses a slow-release carrot special fertilizer capable of improving soil. The fertilizer is prepared from the following raw materials in parts by weight: 20-30 parts of fermented soybean cake, 10-18 parts of humic acid, 6-14 parts of microcrystalline cellulose, 4-8 parts of modified borax, 2-4 parts of sodium silicate, 2-4 parts of EDTA chelated zinc, 2-4 parts of EDTA chelated magnesium, 1-2 parts of calcium hydrophosphate, 60-100 parts of sodium nitrate, 10-20 parts of ammonium chloride, 25-50 parts of ammonium nitrate, 10-18 parts of potassium chloride, 4-12 parts of potassium citrate, 15-25 parts of monopotassium phosphate, 0.3-0.5 part of fermentation bacterial mixture and 3-6 parts of biological insecticide. In the fertilizer disclosed by the invention, the fertilizer efficiency is slowly released, the slow release effect is good, the necessary elements, namely nitrogen, phosphorous and potassium can be provided according to the plant growth and development, and the fertilization times are reduced; meanwhile, the fertilizer has high biodegradability, can effectively improve the soil structure and plays an important role in promoting rooting and strengthening seedlings, activating soil and increasing yield and improving quality.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a special fertilizer for carrots which is slow-release and capable of improving soil. Background technique [0002] Carrots are also known as yellow radishes, clove radishes, cucurbits, and red radishes. The fleshy roots are rich in sucrose, glucose, starch, carotene, potassium, calcium, and phosphorus. Each 100g fresh weight contains 1.67-12.1mg of carotene, which is 5-7 times higher than that of tomato.
