Embodiment 1

[0033] 50 kg of product plus 18.48 kg of polypeptide slow-release urea, 16.3 kg of phosphate fertilizer selected from heavy superphosphate, 5.0 kg of potassium fertilizer selected from potassium sulfate, 1 kg of zinc sulfate, and 0.5 kg of borax. Add 8.72 kilograms of chicken manure and furfural slag particles. (Chicken manure and furfural slag are mixed at a ratio of 1:3 and granulated after they are decomposed).

[0034] The above raw materials are mixed in proportion to 50 kg, weighed and bagged, and each bag is packed with 1 kg of zinc sulfate and 0.5 kg of borax in a small bag.

Embodiment 2

[0036] 50 kg of product plus 12.1 kg of polypeptide slow-release urea, 16.3 kg of phosphate fertilizer selected from diammonium phosphate, 5.0 kg of potassium sulfate selected from potassium sulfate, 1 kg of zinc sulfate, and 0.5 kg of borax. Add 15.1 kilograms of chicken manure and furfural slag particles. (Chicken manure and furfural slag are mixed at a ratio of 1:3 and granulated after they are decomposed).

[0037] The above raw materials are mixed in proportion to 50 kg, weighed and bagged, and each bag is packed with 1 kg of zinc sulfate and 0.5 kg of borax in a small bag.

Embodiment 3

[0039] Add 17 kg of long-acting ammonium bicarbonate to 50 kg of product, 16.3 kg of phosphate fertilizer from diammonium phosphate, 5.0 kg of potassium sulfate from potassium sulfate, 1 kg of zinc sulfate, and 0.5 kg of borax. Add 10.2 kg of chicken manure and furfural slag particles. (Chicken manure and furfural slag are mixed at a ratio of 1:3 and granulated after they are decomposed).

[0040] The above raw materials are mixed in proportion to 50 kg, weighed and bagged, and each bag is packed with 1 kg of zinc sulfate and 0.5 kg of borax in a small bag.

Abstract

The invention relates to a long-acting special fertilizer for dry lands in southern areas of Ningxia, which is characterized in that the long-acting special fertilizer is prepared by mixing, composting, thoroughly decomposing and then granulating a nitrogenous fertilizer, a phosphate fertilizer, a potash fertilizer and microelements with fowl dung and/or furfural residues; the obtained special fertilizer has the following effective fertilizer effects: 15 to 20 percent of nitrogen, 15 percent of phosphorus pentoxide, 5 percent of potassium oxide, 2 percent of zinc sulfate, 1 percent of boric acid, and 40 percent of total nutrient content, wherein the fowl dung and the furfural residues account for 15 to 32 percent of the total weight of the fertilizer and are mixed according to a ratio of 1:3. The long-acting special fertilizer is added with poly-aspartic acid and medium-microelements on the basis of pure urea, thereby not only satisfying the physiological needs of a large amount of nutrient elements of nitrogen, phosphonium, potassium and the like for dry land crops, but also supplementing the medium-microelements necessary for the growth development of the dry land crops to promote the balanced growth of the crops. The long-acting special fertilizer has the advantages of fertilizer supplementation, disease resistance, anti-retroviral capability, no volatilization and drain of nutrient through long-acting slow-release, and high utilization rate, can improve the crop yield, improve the quality and has good effect of increasing the yield, and is widely suitable for the crops of dry land wheat, corn, potato, sunflower and the like.

Description

technical field [0001] The invention relates to the technical field of pesticides and fertilizers, in particular to a long-acting special fertilizer for dry land in southern Ningxia. Background technique [0002] Ningxia's dryland agricultural area includes the central arid zone and the southern mountainous area, accounting for 68% of the whole area, and the existing cultivated land area is 850,000 hm 2 , of which 655,000 hm of dry land 2 , accounting for 86.4% of the total arable land. With global warming, drought occurs year after year, and the generation of arid climate has brought serious drought disasters. Farmers use unreasonable fertilization techniques, causing waste of fertilizer and reducing the effect of using fertilizer to fight drought. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the above-mentioned prior art, and provide a kind of scientific preparation according to the soil fertility level and the ...
