Abstract
Description
Technical field:
[0001] The invention relates to the field of production of liquid fertilizer for foliage spraying. Background technique:
[0002] Liquid fertilizer, as a new type of high-efficiency compound fertilizer, has the following advantages: (1) There will be no dust, smoke, and less pollution during production, application, and transportation; (2) The product does not have moisture absorption and caking problems; (3) ) can be mixed with insecticides, fungicides, and herbicides and can be mixed evenly. (4) It will not segregate like solid fertilizers during storage and transportation, and the quality will be uneven; (5) There are various application methods, which can be sprayed on leaves. Water flushing can also be used for spray irrigation, drip irrigation or watering. It is convenient to use, low in cost and quick in effect; therefore, liquid fertilizer is one of the trends in industrial development in the world today. In the 1990s, the annual liquid fertilizer c...

Embodiment Construction
[0023] The liquid foliar fertilizer is formulated with the following raw materials in the weight ratio: in every 1000 parts of fertilizer, 230 parts of solid ammonium polyphosphate, containing 3 crystal waters and the molecular formula is k 2 HPO 4 ·3H 2 300 parts of dipotassium hydrogen phosphate of O, 20 parts of urea, 430 parts of water, disodium octapolyborate tetrahydrate (molecular formula: Na 2 B 8 o 13 4H 2 O) 12 parts, zinc sulfate heptahydrate (molecular formula: ZnSO 4 ·7H 2 (0) 5 parts, 3 parts of plant growth regulator compound sodium nitrophenolate after adding water to mix and dilute, the ratio of compound sodium nitrophenolate and water is 1: 3.
[0024] The solid ammonium polyphosphate is produced by Caozhou Agrochemical Co., Ltd., Heze Development Zone. It adopts the existing production process and is polymerized with 85% industrial phosphoric acid and urea by heating at 170-180°C. The chain length of ammonium polyphosphate is 3<N<18, and the solid Amm...
