Problems solved by technology

[0003] The conventional method of corn fertilization in the prior art is to apply seed fertilizer at the time of sowing, and perform intertillage and topdressing before corn jointing, which is time-consuming and laborious; and it is difficult to directly act on the corn root system to absorb The efficiency is low, and the probability of loss due to ammonia volatilization and surface runoff is high, and the fertilizer utilization rate is low

Embodiment 1

[0026] According to the need to produce one ton of fertilizer: 235kg of urea, 105kg of monoammonium phosphate, 130kg of potassium chloride, 5kg of boron fertilizer, 10kg of zinc sulfate, 95kg of attapulgite, 35kg of decomposed stone powder, 250kg of fermented animal manure, and 135kg of peat.

[0027] Mix the above raw materials according to the formula and lift them into the multi-dimensional high-efficiency mixer for 5-10 minutes, and the fully mixed materials flow out to the pulverizer for crushing, and then make round spherical particles in the disc granulator; Drying, cooling, coating, screening machine, the particles are dried in the drying section at low temperature (≤100°C), and then enter the cooling section for air cooling, the air cooling temperature is controlled at 30°C, and the fully cooled materials enter the screening machine to be The powder and large particles are screened out, and then returned to the mixing and granulation system to coat the material; the fi...

Abstract

The invention relates to a special fertilizer for corn. The fertilizer is composite fertilizer or compound fertilizer obtained by adding fillers in nitrogen, phosphorus and potassium according to a certain proportion, and is characterized in that nutrient proportions of nitrogen to phosphorus to potassium is 10-14:4-6:7-9. The fertilizer is small in loss after being applied; nitrogen easily absorbed by plants is released gradually during a hydrolysis or biolysis process, so that the applied fertilizer can be fully utilized by the plants; volatilization loss of nitrogen in soil can be reduced; and formation of nitrate nitrogen is reduced, so that leaching loss and denitrification loss are reduced and further generation and emission of nitrate, nitrite, ammonia and nitrous oxide are reduced. The fertilizer has the advantages of increasing utilization rate of the fertilizer, reducing usage amount of the fertilizer and reducing labor for fertilization, can effectively alleviate the problems of excessive consumption of resources, large pollution of agricultural non-point source and high agricultural production cost, and is green fertilizer capable of promoting sustainable development of the soil resource.

Description

technical field [0001] The invention relates to a fertilizer, in particular to a special corn fertilizer suitable for corn planting areas. Background technique [0002] Corn is the main food crop in our country. It is known as a longevity food. It is rich in protein, fat, vitamins, trace elements, cellulose and polysaccharides. It has become a popular health food and often appears on people's tables. , has great potential to develop food with high nutrition and high biological function; corn is also the raw material of feed and future bio-energy. Difficult to implement. Requirements for one-time fertilization of corn: 1. The nutrient distribution ratio is reasonable, which basically meets the nutrient requirements of corn throughout the growth period; 2. High fertilizer utilization rate and environmental friendliness; 3. No reduction in yield, or even increase in yield; 4. No reduction in quality , and even improve the quality; 4. It is easy to use and can even realize mec...
