Embodiment 1

[0026] The magnesium slag and the pyrite slag are removed from impurities, dried, crushed with a ball mill, and passed through a 100-120 mesh sieve for later use.

[0027] Grind the dried sunflower seed cake and pass through a 80-100 mesh sieve; urea, ammonium sulfate, diammonium phosphate, potassium sulfate, zinc sulfate, manganese sulfate and polyboron are respectively crushed with a pulverizer and passed through a 80-100 mesh sieve for later use.

[0028] Take 100kg of crushed magnesium metal slag, 100kg of pyrite slag and 150kg of biochemical fulvic acid, mix them in the reactor for 3-5 days, take them out and air-dry them, and adjust the water content to 10-15%.

[0029] Add 100kg of crushed sunflower seed cakes, 150kg of urea, 100kg of ammonium sulfate, 100kg of diammonium phosphate, 150kg of potassium sulfate, 15kg of zinc sulfate, and 15kg, 10kg of polyboron and 10kg of attapulgite, add them together into the mixer and stir evenly, then send the evenly stirred raw mate...

Embodiment 2

[0042] The preparation method of the special fertilizer for oil sunflower is the same as in Example 1. The raw material composition and consumption are: 200kg of biochemical fulvic acid, 75kg of magnesium metal slag, 75kg of pyrite slag, 100kg of sunflower seed cake, 100kg of ammonium sulfate, 120kg of urea, phosphoric acid Monoammonium 100kg, potassium sulfate 180kg, zinc sulfate 15kg, manganese sulfate 15kg, polyboron 10kg, bentonite 10kg.

[0043] In the special fertilizer for oil sunflower prepared above, it contains 18% of organic matter, 11% of N, and 11% of P 2 o 5 5%, K 2 O 9%, in addition to containing silicon, calcium, magnesium, zinc, manganese, boron and other medium and trace elements.

[0044]Using the special fertilizer for oil sunflower prepared in this example, a field test for effect verification was carried out at Jialian Farm, Gucheng Town, Shanyin County, Shuozhou City, Shanxi Province.

[0045] Basic properties of the soil: the soil is moderate soda s...

Abstract

The invention discloses an oil sunflower special fertilizer based on soda saline soil. The oil sunflower special fertilizer is prepared by blending the following components serving as raw materials in parts by weight: 10-30 parts of biochemical fulvic acid, 5-15 parts of magnesium slag, 5-15 parts of pyrite cinders, 5-20 parts of sunflower seed cake meals, 10-30 parts of urea, 10-15 parts of ammonium sulfate, 10-20 parts of ammonium phosphate, 10-30 parts of potassium sulfate, 1-5 parts of zinc sulfate, 1-5 parts of manganese sulfate, 1-5 parts of poly-boron and 1-5 parts of a granulation binder. According to the oil sunflower special fertilizer disclosed by the invention, aiming at the characteristics of strong alkalinity, high degree of alkalization and poor physical and chemical properties of the soda saline soil, and considering a nutritional requirement rule of oil sunflowers, organic and inorganic matters are combined together, macro-elements are combined with medium elements and microelements, the nutrition is overall and balanced, the nutrition necessary for the whole growth stages of the oil sunflowers can be provided, meanwhile, the pH value of the soda saline soil is reduced, the soil structure is improved, and the soil fertility is improved, so that the output and quality of the oil sunflowers are significantly improved.

Description

technical field [0001] The invention relates to a special fertilizer, in particular to a special fertilizer suitable for oil sunflower planted on soda saline soil. Background technique [0002] Soil salinization is a worldwide problem. my country has a total of 99.13 million hectares of saline-alkali land, of which the inland saline-alkali land area is the largest, accounting for about 69% of the national saline-alkali land. The inland saline-alkali soil has strong alkalinity, high degree of alkalization, poor soil tillability, and great difficulty in improvement. [0003] Oil sunflower has strong salt-alkali tolerance and can grow normally on medium-to-severe saline-alkali land, and is widely planted in inland saline-alkali areas. The fertilizer requirement law of oil sunflower is different from that of ordinary sunflower, and the oil sunflower grown on saline-alkali soil and the oil sunflower grown on non-saline-alkali soil have different fertilizer requirements. [000...
