Embodiment 1

[0022] The nitrogen in the compound fertilizer is partly provided by urea, partly by ammonium sulfate and monoammonium phosphate, and phosphorus is provided by monoammonium phosphate and superphosphate (appropriately select some superphosphate to produce compound fertilizer, on the one hand Playing the role of binder is beneficial to granulation. On the other hand, calcium superphosphate contains a certain amount of calcium, magnesium, sulfur, silicon and trace elements), and potassium is provided by potassium sulfate. The urease inhibitor is hydroquinone and the nitrification inhibitor is 3,5-dimethylpyrazole. The auxiliary materials are attapulgite powder and lignite powder with a fineness of 100-200 mesh.

[0023] The weight of each raw material used is as follows: 375.8kg urea, 50kg ammonium sulfate, 138.5kg monoammonium phosphate, 50kg superphosphate (containing P 2 o 5 6%), 280kg potassium sulfate, 4kg compound inhibitor, 50kg attapulgite powder, 70kg lignite powder. ...

Embodiment 2

[0027] The nitrogen in the compound fertilizer is partly provided by urea, partly by monoammonium phosphate, phosphorus by monoammonium phosphate, and potassium by potassium sulfate. The urease inhibitor is hydroquinone, the nitrification inhibitor is dicyandiamide, and the auxiliary material is attapulgite powder or bentonite.

[0028] The weight of each raw material used is as follows: 374.6kg urea, 230.8kg monoammonium phosphate, 320kg potassium sulfate, 4kg compound inhibitor, 75kg attapulgite powder or bentonite.

[0029] The above-mentioned raw materials are mixed according to the corresponding ratio, crushed, granulated, dried, sieved, and then measured and packaged to obtain the special long-acting compound fertilizer for carrots. This fertilizer is suitable for soils with a high supply capacity of phosphorus and potassium, and it is enough to apply 50kg / mu at one time before site preparation.

[0030] Example 3

Embodiment 3

[0032] Nitrogen in the compound fertilizer is provided by urea and monoammonium phosphate, phosphorus is provided by monoammonium phosphate, and potassium is provided by potassium sulfate. The urease inhibitor is N-butylthiophosphoric triamide, the nitrification inhibitor is 3,4-dimethylpyrazole phosphate, and the auxiliary materials are bentonite and weathered coal powder with a fineness of 100-200 mesh.

[0033] The weight of each raw material used is as follows: 459.8kg urea, 153.8kg monoammonium phosphate, 280kg potassium sulfate, 5.8kg compound inhibitor, 50kg bentonite, 55kg weathered coal powder.

[0034] Firstly, the compound inhibitor and weathered coal powder are fully mixed, and then mixed with other crushed raw materials according to the corresponding proportion, then granulated, dried, sieved, measured and packaged, and made into a long-term compound fertilizer for carrots. This fertilizer is suitable for soil with a high level of phosphorus content in the soil, a...

Abstract

The invention relates to a special slow-release long-acting compound fertilizer for carrot and an application method for the special slow-release long-acting compound fertilizer. The fertilizer is composed of active ingredients and auxiliary materials, wherein the active ingredients comprise, in parts by weight, 20-25 parts of nitrogen, 8-12 parts of phosphorus (P2O5), 14-18 parts of potassium (K2O), and an inhibitor with an addition amount which is 2-4% of the dosage of nitrogen in the compound fertilizer, wherein the inhibitor is a composite inhibitor composed of a urease inhibitor and a nitrification inhibitor at a weight ratio of 1: (2-5); the urease inhibitor is hydroquinone or N-butyl thiophosphoramide; and the nitrification inhibitor is dicyandiamide, 2-chloro-6-(trichloromethyl) pyridine, 2-amino-4-chloro-6-methyl pyridine, 3,4-dimethylpyrazole phosphate, 3,5-dimethylpyrazole or 3,5-dimethylpyrazole phosphate. The fertilizer is capable of meeting the needs of a whole growth period on nutrients by being applied once before carrot planting, high in yield, and excellent in quality.

Description

technical field [0001] The invention relates to a special fertilizer for carrots and an application method thereof, in particular to a special slow-release long-acting compound fertilizer and an application method thereof developed according to the nutrient requirement characteristics of carrots and the transformation characteristics of main mineral nutrients in soil. Background technique [0002] Carrot (Daucus carota) is a biennial plant of the genus Carrot in the Umbelliferae family. It is a semi-cold-resistant vegetable with rich nutrition and is known as "little ginseng". According to statistics, my country's carrot planting area is close to 40% of the world's total carrot planting area, and its total output accounts for 1 / 3 of the world's total output. It is well-deserved that it is the world's largest carrot producer. In recent years, the planting area and total output of carrots have continued to grow rapidly. However, since 1996, the yield per unit area of ​​carrot...
