preparation example Construction

[0015] The present invention also provides the preparation method of above-mentioned composition, implement according to the following steps:

[0016] Step 1, take the following materials according to mass percentage: urea 15% ~ 25%, magnesium sulfate 4% ~ 7%, magnesium chloride 20% ~ 30%, yuanming powder 40% ~ 50%, calcium powder 30% ~ 35%, Zinc sulfate 0.05%~0.08%, boron powder 0.06%~0.1%, the balance is ammonium sulfate, the sum of the mass percentages of the above substances is 100%;

[0017] Step 2, put urea into the melt tank, heat it to 170°C-180°C with a steam jacket with a pressure of 29.4MPa-39.2MPa to make it into a molten state, and then put the rest of the raw materials except urea into the drum In the granulator, spray molten urea under the condition of rotation;

[0018] Step 3: Send the material in agglomerated state to a rotary dry granulator, heat the material to 95°C-110°C for granulation, and then send it to a screening machine for anti-caking treatment by...

Embodiment 1

[0033] Take the following materials according to mass percentage: 15% urea, 5% magnesium sulfate, 20% magnesium chloride, 50% sodium sulfate, 30% calcium powder, 0.07% zinc sulfate, 0.1% boron powder, and the balance is ammonium sulfate; Put the taken urea into the melt tank, heat it to 180°C with a steam jacket with a pressure of 33MPa to make it into a molten state, and then put the rest of the raw materials except urea into the drum granulator, under the condition of rotation Spray down the molten urea; send the material in agglomerated state to the rotary dry granulator, heat the material to 100°C for granulation, and then send it to the sieving machine, and it will be ready after coating and anti-caking treatment.

Embodiment 2

[0035] Take the following materials according to mass percentage: 20% urea, 4% magnesium sulfate, 30% magnesium chloride, 45% sodium sulfate, 35% calcium powder, 0.05% zinc sulfate, 0.06% boron powder, and the balance is ammonium sulfate; The urea taken is put into the molten slurry tank, heated to 170°C with a steam jacket with a pressure of 39.2MPa to make it into a molten state, and then the rest of the raw materials except urea are put into the drum granulator. Spray molten urea under certain conditions; send the material in agglomerated state to a rotary dry granulator, heat the material to 95°C for granulation, and then send it to a screening machine for anti-caking treatment by coating.

Abstract

The invention discloses a fertilizer composition for fruit and vegetable fertilizer application. The fertilizer composition consists of the following substances in percentage by mass: 15-25 percent of urea, 4-7 percent of magnesium sulfate, 20-30 percent of magnesium chloride, 40-50 percent of anhydrous sodium sulphate, 30-35 percent of calcium powder, 0.05-0.08 percent of zinc sulfate, 0.06-0.1 percent of boron powder and the balance of ammonium sulfate. The problems of low fertilizer nutrient utilization and residual pollution of high-content chemical fertilizer on soil are solved; the fertilizer composition can be used in the whole process during grain and commercial crop growth period, does not contain biuret and chloride ions and is safe and reliable; and moreover, the fruit is smooth in peel, fresh in color, good in flavor, high in hardness and durable in storage.

Description

technical field [0001] The invention belongs to the technical field of chemical fertilizers, and relates to a fertilizer composition for topdressing fertilizers on fruits and vegetables and a preparation method thereof. Background technique [0002] Most of the nutrient ratios of products in my country's current chemical fertilizer market can only be used as base fertilizers. In addition, the fertilizer effect period of compound fertilizers is generally about 60 days due to the limitation of nitrogen fertilizers, which cannot meet the nutrient needs of crops throughout the growth period; there is also the domestic market High-priced potassium sulfate is mainly used as sulfur source fertilizer, and farmers have used simple fertilizer for a long time, resulting in low utilization of fertilizer nutrients. At the same time, high-content chemical fertilizers will cause residual pollution to the soil and affect the food safety of fruits and vegetables. Contents of the invention ...
