Abstract

The invention relates to potassium polyphosphate slow-release fertilizer for sugarcane, and a production method of the potassium polyphosphate slow-release fertilizer. The potassium polyphosphate slow-release fertilizer is prepared from the following raw materials in parts by weight: 45-60 parts of urea, 25-28 parts of potassium polyphosphate, 30-35 parts of biochemical potassium fulvate, 0.2-0.4 part of magnesium sulfate, 0.2-0.3 part of calcium chloride, 1-1.5 parts of trace elements, 2-5 parts of tea saponin, 8-10 parts of peanut bran, 5-10 parts of bone meal, 10-15 parts of rotten chicken manure and 10-15 parts of bentonite. The potassium polyphosphate slow-release fertilizer for the sugarcane is prepared according to the nutrient uptake features of sugarcane growth; the potassium polyphosphate slow-release fertilizer can provide multiple nutrient elements needed by the sugarcane growth; furthermore, the nutritional ingredients in the fertilizer can be slowly released, so that the fertilizer efficiency is lasting, and the utilization rate of the fertilizer is facilitated to be increased; the potassium polyphosphate slow-release fertilizer has the effects of increasing both production and income and increasing the sugar content of the sugarcane.

Description

technical field [0001] The invention relates to a fertilizer, in particular to a potassium polyphosphate slow-release fertilizer for sugarcane and a production method thereof, belonging to the technical field of fertilizer production. Background technique [0002] Sugarcane is the genus Saccharum ( Saccharum ) in general, native to tropical and subtropical regions. Sugarcane is an important raw material for the manufacture of sucrose, with a wide planting area and high economic value, especially in Guangxi, my country. The sugarcane stalks are upright, thick and juicy, often covered with white powder on the surface, the leaves are alternate, with small sharp teeth on the edges, and the flower spikes are compound racemes. Sugarcane tastes sweet, astringent, mild in nature, and non-toxic. It is rich in sugar, water, multivitamins, protein, calcium, iron and other substances. It has the effect of clearing away heat and promoting body fluid, and is very popular among people. ...
