Problems solved by technology
It is also beneficial from the perspective of protecting the ecological environment and reducing the damage caused by wind and sand, but it makes fertilization difficult, and the nutrients nitrogen, phosphorus, potassium, trace elements and organic fertilizers required by corn seedlings cannot be supplemented, and the growth of seedlings is slow. Sunshine resources are abundant, but the vegetative body is too small, which will affect photosynthesis and further increase the yield
Applying ordinary simple fertilizers and compound fertilizers in the holes can easily cause burning of seeds, lack of seedlings and broken rows, and affect the number of spikes
Such as transplanting and supplementing seedlings, resulting in uneven growth of large and small seedlings, affecting the maturity period and resulting in reduced production

A granular corn seed fertilizer is prepared from ammonium sulfate, urea, diammonium phosphate, superphosphate, K fertilizer, trace elements and fermented organic fertilizer through proportional mixing, pulverizing, adding water and granulating. Its advantages are high germination rate (more than 97%), strong seedlings and high yield increased by 11.2%.
Description
technical field [0001] The invention relates to a corn seed fertilizer. Background technique [0002] my country is an area with a lot of people and little land, such as: Jiangsu, Shandong, Henan, Hebei and other wheat stubble planting corn, which is in late May to mid-to-late June. During this period, there are often alternating seasons of drought and rain. Plowing and sowing tend to lose water in dry years, affecting seedling emergence. Too much rainfall makes drainage difficult, and stiff seedlings are prone to appear. Since the mid-1980s, with the promotion of hybrid corn, the method of direct seeding with stubble has been adopted to prevent the above-mentioned situation. It is also beneficial from the perspective of protecting the ecological environment and reducing the harm of wind and sand, but it makes it difficult to fertilize, and the nutrients nitrogen, phosphorus, potassium, trace elements and organic fertilizers required by the co...
