Embodiment 1

[0042] This embodiment first provides a kind of slow-release special fertilizer for peanuts, which is suitable for peanut fields with a continuous cropping period of 1-3 years. The layer is made up of the raw materials of following components by weight:

[0043]

[0044]

[0045] The present embodiment further provides the specific preparation method of the above-mentioned peanut slow-release special fertilizer, as follows:

[0046] (1) Prepared by a high-tower granulation process, the above-mentioned urea is melted (132.5°C) into a urea liquid with good fluidity, and then pumped to the mixing tank at the top of the high-tower tower, and the above-mentioned biochar, potassium sulfate, manganese sulfate, sulfuric acid Ferrous iron, sodium molybdate, attapulgite and borax are measured separately and transported to the mixing tank on the top of the tower, stirred and mixed with urea liquid to form a uniform slurry, and then sprayed into small droplets by the rotary nozzle o...

Embodiment 2

[0052] A special slow-release fertilizer for peanuts, suitable for peanut fields with a continuous cropping period of 1-3 years, in granular form, including a first functional layer, a second functional layer and a surface film layer arranged from the inside to the outside, and each layer consists of the following parts by weight Raw material composition of components:

[0053]

[0054] The preparation method is the same as in Example 1.

[0055] Application effect:

[0056] The amount of special fertilizer per mu is 40kg, and it is applied to the soil at one time with machinery during the peanut sowing period. After the fertilizer was applied, the peanuts grew well. Compared with the control group, the incidence of peanut diseases and insect pests decreased by 19%, and the peanut yield increased by 20%.

Embodiment 3

[0058] A slow-release special fertilizer for peanuts, suitable for peanut fields with a continuous cropping period of 4-6 years, in granular form, including a first functional layer, a second functional layer and a surface film layer arranged from the inside to the outside, and each layer consists of the following parts by weight Raw material composition of components:

[0059]

[0060] The preparation method is the same as in Example 1.

[0061] Application effect:

[0062] The amount of special fertilizer per mu is 40kg, and it is applied to the soil at one time with machinery during the peanut sowing period. After the fertilizer was applied, the peanuts grew well. Compared with the control group, the incidence of peanut diseases and insect pests decreased by 23%, and the yield of peanuts increased by 24%.

Abstract

The invention relates to the technical field of soil fertilizers, and especially relates to a slow release fertilizer specially used for peanuts, and a preparation method thereof. The slow release fertilizer specially used for peanuts is granular, and comprises a first functional layer, a second functional layer and a surface film layer which are arranged from the inside to the outside, and each layer comprises raw material components according to a specific formula. The slow release fertilizer specially used for peanuts has an excellent slow release effect, effectively improves the utilization rate of inorganic fertilizers such as a nitrogen fertilizer, a potassium fertilizer and calcium powder in the peanut planting process, and avoids resource waste and environmental pollution; the slowrelease fertilizer specially used for peanuts aims at solving a series of problems caused by continuous cropping of peanuts, effectively reduces soil-borne diseases, improves the soil environment, enhances the adversity resistance of crops, and creates a good environment for the growth and development of crops; and the yield of peanuts is further increased by improving the peanut planting environment and providing corresponding fertilizer nutrients.

Description

technical field [0001] The invention relates to the technical field of soil fertilizers, in particular to a special slow-release fertilizer for peanuts and a preparation method thereof. Background technique [0002] Peanut is an important economic crop in my country and one of the main oil varieties of high-quality edible oil. The majority of farmers pay more and more attention to peanut cultivation, and their investment in peanut cultivation has gradually increased. In many areas, there is a phenomenon of blind planting. The growth of any crop is inseparable from nutrients, and the nutrient supply in the soil alone cannot satisfy the better growth of crops. Therefore, fertilizers play an irreplaceable role in ensuring crop growth and yield. Many studies have shown that rational fertilization is an effective way to increase peanut yield and improve quality. Blind fertilization will waste fertilizer sources, and long-term use will cause damage to the soil aggregate structure...
