Problems solved by technology

[0003] At present, there are also systematic studies on strawberry fertilization technology in my country. Although most farmers have realized the significance of formula fertilization, they do not apply it to strawberry fertilizer much, and topdressing inorganic nutrients rarely consider the nutritional characteristics and fertilizer absorption rules of strawberries. , the conventional 45% compound fertilizer is often applied, which affects the yield and quality

Embodiment 1

[0021] Example 1 Preparation of 1000 kg of special fertilizer for strawberries

[0022] Raw material urea (46%) 235kg, ammonium sulfate 202 kg, monoammonium phosphate (N11-P 2 o 5 51) 78kg, potassium sulfate (K 2 O 50%) 353kg, magnesium sulfate (20%) 10kg, copper sulfate pentahydrate (25%) 8kg, ferrous sulfate (19%) 9kg, zinc sulfate heptahydrate (23%) 9kg, peat 96kg, mix the above raw materials Crushed, put into a blender and stirred evenly to make powdered strawberry special fertilizer, then granulate the powdered strawberry special fertilizer, dry at 60-80°C, cool and pass through the grading rotary sieve (finished granules 2-4mm in diameter), it is a special fertilizer for strawberries in granular form. The total effective nutrient content in Strawberry Special Fertilizer 1 is 37.336%, of which nitrogen (N) is 15.708%, phosphorus pentoxide (P 2 o 5 ) 3.978%, potassium oxide (K 2 O) 17.65%. Magnesium, copper, iron, and zinc are 0.2%, 0.2%, 0.17%, and 0.207%, respecti...

Embodiment 2

[0024] Example 2 Prepare 1000 kg of special fertilizer for strawberries

[0025] Weigh raw material urea (46%) 242kg, ammonium sulfate 200 kg, monoammonium phosphate (N11-P 2 o 5 51) 79kg, potassium sulfate (K 2 O 50%) 360kg, magnesium sulfate (20%) 10kg, copper sulfate pentahydrate (25%) 10kg, ferrous sulfate (19%) 10kg, zinc sulfate heptahydrate (23%) 9kg, peat 80kg, mix the above raw materials Crushed, put into a blender and stirred evenly to make powdered strawberry special fertilizer, then granulate the powdered strawberry special fertilizer, dry at 60-80°C, cool and pass through the grading rotary sieve (finished granules 2-4mm in diameter), it is a special fertilizer for strawberries in granular form 2.

Abstract

The invention discloses a strawberry special-purpose fertilizer and its preparation method and use. The strawberry special-purpose fertilizer comprises: by weight, 23.5 to 25.1% of urea, 20.2 to 22.1% of ammonium sulfate, 7.8 to 8.2% of monoammonium phosphate, 35.3 to 36.5% of potassium sulfate, 1% of magnesium sulfate, 0.8 to 1.0% of copper sulfate, 0.9 to 1.0% of ferrous sulfate, 0.9% of zinc sulfate and 4.2 to 9.6% of peat. The preparation method comprises the following steps of weighing the raw materials according to the weight ratio, mixing, crushing, putting the crushed raw materials into a stirrer, and uniformly mixing to obtain the strawberry special-purpose fertilizer which is powder. The strawberry special-purpose fertilizer is developed according to strawberry nutritional characteristics in growth and according to special requirements on a soil environment and a fertilizer, has obvious effects of promoting good growth of strawberries, improving strawberry quality and reducing a cost, and provides an important technical support for healthy development of a strawberry industry.

Description

technical field [0001] The invention relates to a fertilizer for agricultural production, in particular to a special fertilizer required for strawberry production and its preparation method and application. Background technique [0002] In recent years, my country's strawberry industry has developed rapidly, bringing obvious economic and social benefits to the main production areas. In some areas, strawberry planting has also become a pillar industry in the local rural economy. By 2011, my country's strawberry planting area has reached 100,000 hectares, spread all over the country, with a total output of 1.88 million tons, and exports about 100,000 tons of strawberries every year, becoming the world's largest strawberry production and processing exporter. [0003] At present, there are also systematic studies on strawberry fertilization technology in our country. Although most farmers have realized the significance of formula fertilization, they do not apply it to strawberry...
