Problems solved by technology

However, the coating materials currently used for coated slow-release fertilizers are usually non-fertilizer polymers, which have low effective fertilizer content, high product costs, and high prices of non-fertilizer polymers, which will also bring risks to the soil environment.
At present, in the preparation of slow-release fertilizers, affected by the cost of membrane materials and production processes, the price of slow-release fertilizers is relatively high, which limits its promotion and application; destroy

Abstract

The invention relates to potassium polyphosphate strawberry slow release fertilizer and a production method thereof. The potassium polyphosphate strawberry slow release fertilizer is prepared from the following raw materials in parts by weight: 50 to 60 parts of urea, 70 to 80 parts of potassium polyphosphate, 0.5 to 0.8 part of magnesium nitrate, 0.5 to 0.7 part of calcium nitrate, 1.8 to 2.2 parts of microelement, 8 to 10 parts of bone meal, 6 to 10 parts of ammonium humate, 10 to 15 parts of matured chicken manure, 2 to 4 parts of alcohol waste liquid, 10 to 15 parts of medicine powder and 15 to 20 parts of slow release agent. The potassium polyphosphate strawberry slow release fertilizer produced by the invention can be prepared according to fertilizer requiring characteristics of strawberry growth; the produced potassium polyphosphate strawberry slow release fertilizer has rich and balance nutrition, contains rich nutrients and medium-trace element and can quickly supplement nutrients required by strawberry in a long-acting mode; furthermore, nutritional ingredients in the fertilizer can be slowly released, so that fertilizer efficiency is long, utilization rate of the fertilizer is beneficial to being improved, and effects of increasing yield and revenue and improving strawberry quality are achieved.

Description

technical field [0001] The invention relates to a fertilizer, in particular to a potassium polyphosphate slow-release fertilizer for strawberries and a production method thereof, belonging to the technical field of fertilizer production. Background technique [0002] Strawberry (Latin scientific name: Fragaria ananassa Duchesne), Rosaceae, Strawberry is a perennial herb, a red fruit, also known as pineapple strawberry, cranberry, raspberry, ground berry, etc., with a heart-shaped appearance, delicious red and tender, The pulp is juicy and has a special intense fruity aroma. Strawberries are sweet in taste and cool in nature. They have the effects of nourishing the lungs and promoting body fluid, invigorating the spleen and harmonizing the stomach. Eating a few strawberries after a meal can help digestion and appetizing, and invigorate the spleen and promote body fluid. According to measurements, every 100 grams of strawberry pulp contains 8 to 9 grams of sugar, 0.4 to 0.6 g...
