Embodiment 1

[0016] A rice fertilizer with high fertilizer utilization rate, its raw materials include: 80kg of ammonium nitrate, 60kg of ammonium sulfate, 25kg of superphosphate, 18kg of potassium Epsom salt, 6kg of slow release agent, 0.5kg of epoxy soybean oil, 0.2kg of zinc humate , manganese humate 0.4kg, sodium nitrophenolate 1kg, triacontanol 2kg, coating agent 2kg.

[0017] The sustained-release agent is composed of weathered coal, medical stone powder, vermiculite powder and mica compound in a weight ratio of 4:2:3:2. The mica composite was prepared by the following process: Stir 10kg of mica powder and 50kg of nitric acid solution with a concentration of 1.15mol / L for 12min at a stirring temperature of 100°C, add 1kg of P123 and 2kg of polystyrene microsphere emulsion and continue stirring for 5min, cool down, wash, and dry. Calcined for 50 minutes, the calcined temperature was 800° C., cooled to room temperature, and pulverized to obtain the mica composite.

Embodiment 2

[0019] A rice fertilizer with high fertilizer utilization rate, its raw materials include: 120kg of ammonium nitrate, 40kg of ammonium sulfate, 45kg of superphosphate, 10kg of potassium Epsom salt, 14kg of slow release agent, 0.1kg of epoxy soybean oil, 0.8kg of zinc humate , manganese humate 0.1kg, sodium nitrophenolate 1.4kg, triacontanol 1kg, coating agent 5kg.

[0020] The sustained-release agent is composed of weathered coal, medical stone powder, vermiculite powder and mica compound in a weight ratio of 1:5:1:4. The mica composite was prepared by the following process: Stir 4kg of mica powder and 80kg of nitric acid solution with a concentration of 0.9mol / L for 20min at a temperature of 90°C, add 2kg of P123 and 1kg of polystyrene microsphere emulsion and continue to stir for 12min, cool down, wash, and dry. Calcined for 40 minutes, the calcined temperature was 850° C., cooled to room temperature, and pulverized to obtain the mica composite.

Embodiment 3

[0022] A rice fertilizer with high fertilizer utilization rate, its raw materials include: 110kg of ammonium nitrate, 45kg of ammonium sulfate, 40kg of superphosphate, 12kg of potassium Epsom salt, 12kg of slow release agent, 0.2kg of epoxy soybean oil, 0.6kg of zinc humate , manganese humate 0.2kg, sodium nitrophenolate 1.3kg, triacontanol 1.2kg, coating agent 4kg.

[0023] The sustained-release agent is composed of weathered coal, medical stone powder, vermiculite powder and mica compound in a weight ratio of 2:4:1.5:3.5. The mica composite was prepared by the following process: 6kg of mica powder and 70kg of 1mol / L nitric acid solution were stirred for 18min at a stirring temperature of 92°C, 1.8kg of P123 and 1.3kg of polystyrene microsphere emulsion were added and stirred for 10min, cooled, washed, and dried , calcined for 44min, the calcined temperature was 840°C, cooled to room temperature, and pulverized to obtain the mica composite.

Abstract

The invention discloses paddy rice fertilizer with a high fertilizer utilization rate. The paddy rice fertilizer is prepared from the following raw materials in parts by weight: 80 to 120 parts of ammonium nitrate, 40 to 60 parts of ammonium sulfate, 25 to 45 parts of calcium triple superphosphate, 10 to 18 parts of kainite, 6 to 14 parts of slow release agent, 0.1 to 0.5 part of epoxidized soybean oil, 0.2 to 0.8 part of zinc humate, 0.1 to 0.4 part of manganese humate, 1 to 1.4 parts of sodium nitrophenolate, 1 to 2 parts of triacontanol and 2 to 5 parts of film coating agent. The slow release agent is prepared from weathered coal, medical stone powder, vermiculite powder and a mica compound. The mica compound is prepared by adopting the following technology: stirring mica powder and a nitric acid solution; adding P123 and polystyrene microsphere emulsion and continually stirring; cooling, washing, drying, roasting, cooling and crushing.

Description

technical field [0001] The invention relates to the technical field of rice, in particular to a rice fertilizer with high fertilizer utilization rate. Background technique [0002] Rice is one of the most important food crops in my country. Its planting range covers a large area of ​​my country from Hainan Island to Heilongjiang, from East China to Sichuan. According to statistics, my country's rice planting area reaches 453 million mu, accounting for about 30% of my country's grain output, and it is a veritable staple food. [0003] Since the reform and opening up, my country's rice has been greatly developed, but the long-term application of chemical fertilizers has led to serious negative problems such as soil structure damage, fertilizer use efficiency decline, and rice quality reduction. Contents of the invention [0004] Based on the technical problems in the background technology, the present invention proposes a rice fertilizer with high fertilizer utilization ra...
