Embodiment 1

[0033] The compound long-acting iron fertilizer described in the present embodiment comprises 50 kilograms of organic fertilizers, 20 kilograms of furfural slag, 15 kilograms of sulfur, 12 kilograms of ferrous sulfate and 3 kilograms of zinc sulfate fertilizers.

[0034] The organic fertilizer is to adjust the humidity of livestock and poultry manure and animal and plant residues to 45% with plant straw powder, and use a compost turner to turn and ferment for 7 days, so that the temperature can be controlled between 45-70°C, and then use The plant straw powder is prepared by adjusting the material to a moisture content of 30%; then uniformly mixing the acid-adjusting material, trace element fertilizer and fermented organic material in proportion.

[0035] Sulfur powder, dried ferrous sulfate and zinc sulfate powder are passed through a 1mm sieve and mixed evenly with the fermented organic fertilizer according to the above ratio to obtain a compound long-acting iron fertilizer. ...

Embodiment 2

[0039] The compound long-acting iron fertilizer described in the present embodiment comprises 55 kilograms of organic fertilizers, 25 kilograms of citric acid residues, 20 kilograms of sulfur, 10 kilograms of ferrous sulfate and 5 kilograms of magnesium sulfate fertilizers.

[0040] The organic fertilizer is prepared by adjusting the humidity to 40% with plant straw powder from livestock and poultry manure and animal and plant residues, turning and fermenting with a compost turner for 9 days, so that the temperature can be controlled between 45-70°C, and then using plant straw powder to adjust the material to a moisture content of 25%.

[0041] Sulfur powder, dried ferrous sulfate and magnesium sulfate powder are passed through a 1mm sieve and mixed evenly with the fermented organic fertilizer according to the above ratio to obtain a compound long-acting iron fertilizer.

[0042] The obtained fertilizer can be applied directly or after granulation. It can be evenly mixed with...

Embodiment 3

[0045] The preparation process is the same as in Example 1, except that the composite long-acting iron fertilizer includes 30 kg of organic fertilizer, 30 kg of furfural slag, 10 kg of sulfur, and 8 kg of ferrous sulfate.

[0046] The organic fertilizer is prepared by adjusting the humidity to 55% with plant straw powder from livestock and poultry manure and animal and plant residues, turning and fermenting with a compost turner for 10 days, so that the temperature can be controlled between 45-70°C, and then using plant straw powder to adjust the material to a water content of 20%.

It also discloses a method for making the compound long-lasting iron fertilizer and the purpose.

Description

technical field [0001] The invention relates to a compound long-acting iron fertilizer for iron-deficiency chlorosis of fruit trees planted in calcareous soil with pH>7.0, a preparation method and application thereof, and belongs to the field of fertilizers suitable for farmland. Background technique [0002] Iron is one of the essential micronutrients for plants and plays an indispensable role in plants. Iron-deficiency chlorosis of fruit trees is a common nutritional disorder on calcareous soils. It occurs widely in my country, and crops are commonly affected in Southwest, Northwest, North China and other regions. Calcareous soil has a pH of 7.0 to 8.5, a calcium carbonate content of 5 to 18%, and an organic matter content of generally less than 1%, lacking available nitrogen and available phosphorus. According to reports, the incidence of orchards on calcareous soil in my country is as high as 20% to 60%. Plants lack iron and lose chlorosis, and photosynthesis is hin...
