Embodiment 1

[0016] A long-acting topdressing-free fertilizer, which consists of: urea, diammonium phosphate, potassium chloride, zinc fertilizer, active silicon fertilizer, amino acid granular fertilizer, the parts by weight of the urea are 360-380, and the phosphoric acid The parts by weight of diammonium is 340-360, the parts by weight of described potassium chloride is 160-180, the parts by weight of described diammonium phosphate is 2.5-3, the parts by weight of described active silicon fertilizer The number is 3.3-3.8, and the parts by weight of the amino acid granular fertilizer is 103-104.

[0017] The dosage per mu of the present invention is 35-45 kg, which can satisfy the nutrition of crops throughout the growth period, wherein nitrogen element (abbreviated as urea) acts as the first artificially synthesized organic fertilizer in the growth period of crops, which does not remain in the soil and does not have any Hazardous substances, long-term use has no adverse effects. Urea is...

Abstract

Provided is a long-acting topdressing-free fertilizer. A conventional blended fertilizer is not added with trace elements and amino acid particles as fillers, and crops have unbalanced nutrition-absorption, so that an excellent effect cannot be achieved. The long-acting topdressing-free fertilizer comprises urea, diammonium phosphate, potassium chloride, zinc fertilizer, active silicon fertilizerand amino acid granular fertilizer, and is characterized by comprising, by weight, 360-380 parts of the urea, 340-360 parts of the diammonium phosphate, 160-180 parts of the potassium chloride, 2.5-3parts of the diammonium phosphate, 3.3-3.8 parts of the active silicon fertilizer, and 103-104 parts of the amino acid granular fertilizer. The long-acting topdressing-free fertilizer is used for fertilization.

Description

Technical field: [0001] The invention relates to a long-acting topdressing-free fertilizer. Background technique: [0002] Conventional blended fertilizers do not add trace elements and filler amino acid particles, so the crops absorb nutrients unevenly and cannot achieve superior results. Invention content: [0003] The purpose of the present invention is to provide a long-acting topdressing-free fertilizer. [0004] Above-mentioned purpose realizes by following technical scheme: [0005] A long-acting topdressing-free fertilizer, which consists of: urea, diammonium phosphate, potassium chloride, zinc fertilizer, active silicon fertilizer, amino acid granular fertilizer, the parts by weight of the urea are 360-380, and the phosphoric acid The parts by weight of diammonium is 340-360, the parts by weight of described potassium chloride is 160-180, the parts by weight of described diammonium phosphate is 2.5-3, the parts by weight of described active silicon fertilizer T...
