Problems solved by technology

The second is the mixed sowing of seed fertilizer and seeds. Although the amount of seed fertilizer is not large, some fertilizers are not suitable for mixed sowing with seeds. If the mixed sowing makes the seeds and fertilizers directly contact, it will cause burning buds or burning seedlings.
The third is to use pure nitrogen fertilizers as seed fertilizers. Some pure nitrogen fertilizers are highly volatile (such as ammonium bicarbonate), and some contain ingredients that have certain corrosive effects on seeds or sprouts (such as urea in urea). biuret), which can easily cause seedling burn

Embodiment 1

[0024] In areas where the soil phosphorus content is suitable, weigh monoammonium phosphate (N content 11%, P 2 o 5 Content 44%) 160 kilograms, ammonium sulfate 100 kilograms, materials are mixed uniformly, obtain 260 kilograms of special seed fertilizers for corn, wherein the mass ratio of monoammonium phosphate and ammonium sulfates is 8:5, namely the nutrient content in the seed fertilizers used during sowing for N 38kg ha -1 , P 2 o 5 70kg ha -1 , S 24kg ha -1 .

[0025] Application method: When sowing, open a ditch to apply seed fertilizer at 5 cm on one side of the sowing row. The depth of the ditch is 5 cm downward from the vertical distance from the seed, and manual application is adopted.

[0026] In the above-mentioned embodiment, the schematic diagram of the plane position of the seed fertilizer strip and the sowing row is as follows: figure 1 As shown, the schematic diagram of the plane position of seed fertilizer and seeds is shown in figure 2 shown.

Embodiment 2

[0028] In areas with high soil phosphorus content, weigh monoammonium phosphate (N content 11%, P 2 o 5 Content 44%) 136 kilograms, 105 kilograms of ammonium sulfate, the material is mixed evenly, obtains 241 kilograms of special seed fertilizers for corn, wherein the mass ratio of monoammonium phosphate and ammonium sulfate is 136: 105, namely the nutrient content in the seed fertilizer applied when sowing for N 36kg ha -1 , P 2 o 5 60kg ha -1 , S 25.5kg ha -1 .

[0029] Application method: When sowing, open a ditch to apply seed fertilizer at 5 cm on one side of the sowing row. The depth of the ditch is 5 cm downward from the vertical distance from the seed, and mechanical application is used.

Embodiment 3

[0031] In 2010 and 2011, field fertilizer efficiency tests were carried out at the Experimental Station of China Agricultural University in Shangzhuang, Haidian District, Beijing, and at the Experimental Station of China Agricultural University in Quzhou, Hebei.

Abstract

The invention discloses a local-regulation-based fertilizing method for seed manure special for corns, which comprises the following step of applying the seed manure special for the corns at one side of each sowing row while sowing, wherein the seed manure special for the corns is composed of a nitrogen fertilizer, a phosphate fertilizer and a sulfur fertilizer; a horizontal distance between the seed manure special for the corns and each sowing row is 5cm-6cm; and a vertical distance between the seed manure special for the corns and corn seeds is 5cm-6cm. According to the growth characteristic of the corns, compared with the habitual manner of applying the seed manure by peasants, the local-regulation-based fertilizing method has the advantages that the efficiency of the manure is increased, the growth in a seedling stage is boosted and the yield is increased. The invention provides a scientific fertilization technology for realizing high yield and high efficiency of the corns; the effect of increasing production is obvious; particuarlly, with the popularization of agricultural mechanization, the seed manure technology is combined with agricultural machinery, so that the practicalapplication value is wider; the combination of agricultural technologies and agricultural machinery is the development direction of modern agriculture and is popularized internationally; and the method disclosed by the invention has a wider market prospect in corn production in China.

Description

technical field [0001] The invention relates to a method for local regulation and fertilization of a special seed fertilizer for corn, and belongs to the technical field of agricultural fertilizers. Background technique [0002] Corn is the third largest economic crop in my country and plays an important role in agricultural production. Achieving high yield and high efficiency of corn is the goal of agricultural development, and cultivating strong seedlings is the first step to obtain high yield and high efficiency. However, in the seedling stage of spring corn, it is often stressed by adverse environments such as low temperature and drought, resulting in slow root growth, small and weak seedlings. In order to cultivate strong seedlings, in recent years, the application of seed fertilizer has become more and more common, and it has also played a certain role in production, laying a good foundation for high yield of corn. Studies have shown that the growth center of corn se...
