Embodiment 1

[0028] A complete compound fertilizer with rare earth humic acid, including the following components (kg): rare earth 3, urea 30, diammonium phosphate 15, monoammonium phosphate 15, potassium nitrate 20, potassium chloride 20, potassium sulfate 20, silicon dioxide 3. Calcium monoxide 3, magnesium oxide 3, zinc sulfate 2, manganese sulfate 2, ferrous sulfate 2, copper sulfate 2, borax 2, ammonium molybdate 2, humic acid 8.

[0029] The preparation method includes the following steps: mixing nitrogen fertilizer urea, phosphate fertilizer diammonium phosphate, monoammonium phosphate, potash fertilizer potassium nitrate, potassium chloride, and potassium sulfate; spraying 2 kilograms of water into the mixture to make a slurry; adding rare earths and remaining materials, and stirring evenly, Granulation is made in the granulating dryer, dried at 80°C, and sieved through 200 meshes to make a powdered product.

[0030] The effect of the rare earth humic acid full-price compound fertilizer...

Embodiment 2

[0032] A complete compound fertilizer with rare earth humic acid, including the following components (kg): rare earth 7, urea 60, diammonium phosphate 30, potassium nitrate 45, silicon dioxide 10, calcium monoxide 10, magnesium oxide 10, zinc sulfate 6 , Manganese sulfate 7, ferrous sulfate 7, copper sulfate 7, borax 7, ammonium molybdate 7, humic acid 15.

[0033] The preparation method is the same as that in Example 1, except that the slurry is sprayed with 5 kilograms of water to prepare a slurry; the granulation drying is drying at 50°C, and then sieved through 20 mesh to produce a finished granule.

[0034] The effect of the compound fertilizer with rare earth humic acid used in corn seedlings: corn yields an average increase of 40% per acre compared with unfertilized corn, which can prevent nutrient deficiency, leaf spot disease, lodging resistance, and good pollination during the seedling stage. No blind particles.

Embodiment 3

[0036] A complete compound fertilizer with rare earth humic acid, including the following components (kg): rare earth 1.5, urea 17, diammonium phosphate 12, monoammonium phosphate 12, potassium nitrate 11, silicon dioxide 2, calcium monoxide 2, magnesium oxide 1. Zinc sulfate 0.5, manganese sulfate 0.5, ferrous sulfate 0.5, copper sulfate 0.5, borax 0.5, ammonium molybdate 0.5, humic acid 1.

[0037] The preparation method is the same as that in Example 1, except that the slurry is sprayed with 1 kg of water to make a slurry; the granulation is dried at 60°C and sieved through 400 mesh to make a powdered product.

[0038] The effect of applying the rare earth humic acid full-price compound fertilizer to cucumber seedlings: Compared with unfertilized cucumbers, the average yield per mu is increased by 50%, and the high yield can be doubled. It can prevent downy mildew and gray mold; Well-proportioned, no deformities, and good taste.

Abstract

The invention relates to a rare earth humic acid complete compound fertilizer and a preparation method thereof. The complete compound fertilizer comprises the following components: rare earths, urea, diammonium phosphate and / or monoammonium phosphate, potassium nitrate and / or potassium chloride and / or potassium sulfate, silica, calcium dioxide, magnesium oxide, zinc sulfate, manganese sulfate, ferrous sulfate, copper sulfate, borax, ammonium molybdate, and humic acid. The preparation method consists of: mixing the nitrogen fertilizer, phosphate fertilizers and potassium fertilizers, spraying 1-5 parts of water to prepare a slurry, adding rare earth and the remaining materials, stirring the materials evenly, and carrying out granulation and drying, thus obtaining the rare earth humic acid complete compound fertilizer. The invention also provides application of the compound fertilizer in plant cultivation. The compound fertilizer provided by the invention has the existing fertilizers lacked advantage of supply of comprehensive nutrient elements to plants.

Description

Technical field [0001] The invention relates to a plant fertilizer, in particular to a preparation method of a rare earth humic acid full-price compound fertilizer. Background technique [0002] Plant virus diseases are a major issue that the world has been solving. Every year, China’s agricultural virus diseases cause huge losses. The crop viruses and diseases such as soybeans, peanuts and vegetables have reduced yields by 20-60%. The use of chemical fertilizers and pesticides affects and destroys the ecological balance, and the pollution caused to the environment is increasingly harmful to human health. In particular, the effective ingredient utilization rate of chemical fertilizers is only 20-30%, which also causes a waste of social wealth and material resources. Therefore, agriculture needs A large number of pollution-free fertilizers that can not only protect the environment, increase yield, but also improve the quality of agricultural and sideline products, and reduce agric...
