Summer black grape special fertilizer with high phosphorus release rate

Abstract

The invention discloses summer black grape special fertilizer with a high phosphorous release rate, and relates to the technical field of fertilizer. The summer black grape special fertilizer is prepared from the following raw materials, in parts by weight: 30-40 parts of ammonium chloride, 20-30 parts of monoammonium phosphate, 17-25 parts of modified phosphate rock powder with a high phosphorousrelease rate, 18-25 parts of potassium chloride, 150-180 parts of decomposed farm manure, 2-4 parts of silicon fertilizer, 3-5 parts of eggshell, 3-5 parts of bone meal, 0.2-0.5 part of nitrificationinhibitor, 0.2-0.4 part of zinc sulfate, 0.2-0.4 part of EDTA (ethylene diamine tetraacetic acid) chelated iron, 0.1-0.3 part of EDTA chelated manganese, 0.1-0.3 part of sodium selenite, 0.5-1 part of sodium borate and 3-7 parts of soil conditioner. The summer black grape special fertilizer uses the modified phosphate rock powder with the high phosphorous release rate and monoammonium phosphate cooperatively, the fertilizer effect is durable and stable, the utilization rate of phosphorus is improved, the ratio of organic and inorganic nutrients in the special fertilizer is reasonable, and thespecial fertilizer can ensure the demands for normal growing and fruiting of summer black grape plants in different stages, and has the outstanding effect on improving the yield and the quality of summer black grapes.
