Embodiment 1

[0021] Embodiment 1, prepare seedling special fertilizer 100kg

[0022] Weigh raw materials ammonium sulfate 40kg (40%), monoammonium phosphate 11kg (11%), superphosphate 14kg (14%), potassium sulfate 25kg (25%), sulfur 5.97kg (5.97%), ferrous sulfate 4kg (4%), 0.03kg (0.03%) of 45% malathion emulsifiable concentrate, the above-mentioned raw materials weighed according to the proportioning are mixed, pulverized, put into an agitator and stirred and mixed evenly to make powdery special fertilizer for seedlings. If the special fertilizer for seedlings in powder form is dried, the drying temperature is 60-80°C, and it is granulated by a granulator to make a special fertilizer for seedlings in granular form.

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

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.
