Example Embodiment

[0021] Example 1. Preparation of 100kg fertilizer for seedlings

[0022] Weigh the raw materials ammonium sulfate 40kg (40%), monoammonium phosphate 11kg (11%), superphosphate 14kg (14%), potassium sulfate 25kg (25%), sulfur 5.97kg (5.97%), ferrous sulfate according to the ratio. 4kg (4%), 45% malathion emulsifiable concentrate, 0.03kg (0.03%), the above-mentioned weighing raw materials are mixed, crushed, put into a mixer and mixed evenly to make powdered seedling fertilizer. For example, the powdered seedling special fertilizer is dried at a drying temperature of 60-80°C, and granulated by a granulator to make granular seedling special fertilizer.

[0023] The above-mentioned special fertilizer for seedlings contains 28.91% of effective total nutrients, of which 9.61% nitrogen (N), phosphorus pentoxide (P 2 O 5 )6.8%, potassium oxide (K 2 O) 12.5%.

Example Embodiment

[0024] Example 2: Preparation of 100kg fertilizer for seedlings

[0025] Weigh the raw materials ammonium sulfate 58kg (58%), monoammonium phosphate 8kg (8%), superphosphate 12kg (12%), potassium sulfate 15kg (15%), sulfur 4kg (4%), ferrous sulfate 2.96 kg (2.96%), 45% malathion EC, 0.04 kg (0.04%), the above-mentioned weighing raw materials are mixed, crushed, put into a mixer and mixed evenly to make a powdered seedling fertilizer. For example, dry the special fertilizer for powdered seedlings at a drying temperature of 60-80°C, and granulate by a granulator to make a special fertilizer for granular seedlings.

[0026] The above-mentioned special fertilizer for seedlings contains 25.43% of effective total nutrients, of which 12.73% nitrogen (N), phosphorus pentoxide (P 2 O 5 )5.2%, potassium oxide (K 2 O) 7.5%.

Example Embodiment

[0027] Example 3 Preparation of 100kg fertilizer for seedlings

[0028] Weigh 42kg (42%) of ammonium sulfate (42%), 15kg (15%) of monoammonium phosphate, 13kg (13%) of superphosphate, 17.98kg (17.98%) of potassium sulfate, 10kg (10%) of sulfur, and ferrous sulfate according to the ratio. 2kg (2%), 45% malathion EC, 0.02kg (0.02%), the above-mentioned weighed raw materials are mixed, crushed, put into a mixer and mixed evenly to make a special fertilizer for powdered seedlings. For example, dry the special fertilizer for powdered seedlings at a drying temperature of 60-80°C, and granulate by a granulator to make a special fertilizer for granular seedlings.

[0029] The above-mentioned special fertilizer for seedlings contains 27.88% of effective total nutrients, of which 10.47% nitrogen (N), phosphorus pentoxide (P 2 O 5 )8.42%, potassium oxide (K 2 O) 8.99%.

Abstract

This invention relates to a seedlings special fertilizer. The feature of this fertilizer lies in: it is mixed accord to weight ratio by ammonium sulfate, ammonium phosphate 40-58%, calcium superphosphate 8-15%, potassium sulfate 12-28%, sulfur 4-10%, ferrous sulfate 2-4%, malathion 0.02-0.04%. It contains total effective nutrients 25 to 30%, nitrogen (N) 9 ~ 14%, phosphorus pentoxide (P2O5) 5 ~ 11%, potassium oxide (K2O) 7 ~ 13%. Seedlings special fertilizer can meet the need of several key elements demand of the entire process of seedling growth, and effectively prevent seedlings yellow and control the main pests.

Description

technical field [0001] The special fertilizer for seedlings of the invention relates to a fertilizer, in particular to a special fertilizer applied on seedlings. Background technique [0002] In recent years, the situation of my country's ecological environment has been very severe. The Chinese government has put forward the idea of ​​the scientific development concept in a timely manner. One of its important contents is to require the concentration of the whole society to use idle land such as barren hills and slopes, roadsides, villages, and communities to carry out tree planting. Afforestation, increasing forest coverage, thereby improving the quality of the ecological environment, promoting the coordinated and sustainable development of the economy, society and the ecological environment, and benefiting the present and future generations. At the same time, Jiangsu Province proposed the strategy of "Green Jiangsu", and Nanjing City proposed the goal of "Humanistic Green Ci...
