Urea synergist and preparation method thereof

Abstract

the invention discloses an urea synergist and a preparation method thereof. The urea synergist comprises following raw materials, by weight, 150 to 200 parts of ammonium sulfate, 120 to 160 parts of potassium dihydrogen phosphate, 10 to 15 parts of ammonium molybdate, 25 to 35 parts of boric acid, 5 to 10 parts of cobaltous chloride, 5 to 10 parts of nickel sulfate, 20 to 30 parts of ethylene diamine tetraacetic acid, 30 to 40 parts of zinc sulfate, 20 to 30 parts of enteromorpha dried powder, 10 to 15 parts of potassium humate fulvate acid, 15 to 25 parts of vulcanic ash, 10 to 15 parts of tea seed cake powder, 50 to 100 parts of modified zeolite powder, and 3 to 6 parts of compound sodium nitrophenolate. The urea synergist is capable of increasing fertilizer efficiency and nitrogen use efficiency of urea, prolonging fertilizer validity period, promoting crop rapid growth, increasing drought resistance and disease resistance, increasing yield significantly, improving crop quality, reducing application amount, reducing additional fertilizers, reducing labor and fertilizer amount, reducing planting cost, and increasing economic benefits of crops.

Description

technical field [0001] The invention relates to a urea synergist and a preparation method thereof, belonging to the technical field of agricultural fertilizers. Background technique [0002] Urea is an important chemical nitrogen fertilizer in my country, and it is also the most important nutrient element that affects crop yield and quality. Urea is not easily absorbed by the soil. Only about 20% of urea in the soil is absorbed by the soil, and it is not reliable, and it is easy to lose with water, resulting in the nitrogen loss of urea. The utilization rate of nitrogen is low, and the loss of nitrogen in farmland is serious, which affects the growth of crops and increases the cost of planting. Therefore, how to improve the utilization rate of urea nitrogen and fertilizer efficiency is an urgent problem to be solved in my country's agricultural production. Contents of the invention [0003] The purpose of the present invention is to provide a urea synergist and a preparati...
