Problems solved by technology

However, no varieties immune to wheat root rot have been found so far. The use of disinfection or irrigation of pesticides requires more labor for the growers on the one hand, and on the other hand, a large amount of pesticides are injected into the soil, which damages the biological chain in the agricultural environment. and all stages of the food chain

Embodiment 1

[0028] Step 1: Clean the disease-free apricot leaves, pulverize them to a particle size of less than 50 mesh, put them in an ethanol solution according to a material-to-liquid ratio of 1g:12ml, extract at 50°C for 90min, filter the extract, and filter the filtrate. Put it into a rotary evaporator and rotate it at a temperature of 70 °C to obtain the extract, and then dry it in a 40 °C oven to obtain the apricot leaf extract;

[0029] Step 2: Weigh by weight 3 parts of apricot leaf extract, 95 parts of humic acid, 460 parts of urea, 230 parts of diammonium hydrogen phosphate, 200 parts of potassium nitrate, 3.5 parts of citric acid chelated manganese and 22 parts of kaolin and mix, Pulverize, sieve, and granulate to obtain fertilizer granules;

[0030] Step 3: Weigh 3 parts of the anti-caking agent and evenly wrap it in the fertilizer granules obtained in step 2 to obtain functional fertilizer.

Embodiment 2

[0032] Step 1: Clean the disease-free apricot leaves, pulverize them to a particle size of less than 50 mesh, put them in an ethanol solution according to the ratio of material to liquid 1g:12ml, extract at 45°C for 85 minutes, filter the extract, and filter the filtrate. Put it into a rotary evaporator and rotate it at 70 °C to obtain the extract, and then dry it in a 30 °C oven to obtain the apricot leaf extract;

[0033] Step 2: Weigh by weight 2 parts of apricot leaf extract, 80 parts of humic acid, 460 parts of urea, 200 parts of diammonium hydrogen phosphate, 170 parts of potassium nitrate, 2 parts of citric acid chelated manganese, 20 parts of kaolin and steps A mixture obtained by grinding, mixing, pulverizing, sieving and granulating to obtain fertilizer granules;

[0034] Step 3: Weigh 2.5 parts of the anti-caking agent and evenly wrap it in the fertilizer particles obtained in step 2 to obtain functional fertilizer.

Embodiment 3

[0036] Step 1: Clean the disease-free apricot leaves, pulverize them to a particle size of less than 50 mesh, put them in an ethanol solution according to a material-to-liquid ratio of 1g:12ml, extract at 50°C for 90min, filter the extract, and filter the filtrate. Put it into a rotary evaporator and steam at a temperature of 70 °C to obtain the extract, and then dry it in an oven at 35 °C to obtain the apricot leaf extract;

[0037] Step 2: Weigh by weight 2.5 parts of apricot leaf extract, 100 parts of humic acid, 500 parts of urea, 240 parts of diammonium hydrogen phosphate, 210 parts of potassium nitrate, 4 parts of citric acid chelated manganese, 25 parts of clay and the steps A mixture obtained by grinding, mixing, pulverizing, sieving and granulating to obtain fertilizer granules;

[0038] Step 3: Weigh 3.5 parts of the anti-caking agent and evenly wrap it in the fertilizer granules obtained in Step 2 to obtain functional fertilizer.

Abstract

The invention discloses a functional fertilizer and a preparation process thereof, and relates to the technical field of fertilizers. The functional fertilizer prepared by the invention comprises apricot leaf extract, humic acid, urea, diammonium hydrogen phosphate, potassium nitrate, citric acid chelated manganese, filler and anti-caking agent. Fertilizer granules are obtained by granulating a mixture of apricot leaf extract, humic acid, urea, diammonium hydrogen phosphate, potassium nitrate, citric acid chelated manganese and fillers, and then wrapping anti-caking agents in the fertilizer granules to obtain functional fertilizers . The preparation process of the invention is simple and environment-friendly, and is suitable for batch production. The functional fertilizer prepared by the invention has a high absorption effect, can play a good role in preventing and treating wheat root rot, and the addition of humic acid can also improve soil structure and is friendly to the ecological environment.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a functional fertilizer and a preparation process thereof. Background technique [0002] China is a big country in agricultural production, and fertilizer is a strategic material to ensure national food security and the material basis for maintaining and improving soil fertility to achieve sustainable agricultural development. Chemical fertilizers are still an important means of production in current agricultural production. Plants have a very low absorption and utilization rate of chemical fertilizers in soil. According to the current comprehensive scientific and technological level of agriculture in my country, the utilization rate of agricultural crop fertilization in China is only about 30%, resulting in a large number of Fertilizer loss and waste and environmental pollution. In addition, for a long time, in agriculture, people blindly pursued high yield and increased inc...
