Abstract

The invention relates to an algae medium trace element compound granular fertilizer, and belongs to the field of compound fertilizers. The fertilizer is prepared by treating natural wild or artificially cultured algae and concentrating, granulating and mixing the effective ingredients of the algae and organic raw materials treated by physical and chemical methods and containing medium trace element minerals and humic acid. The fertilizer comprises the following components in percentage by weight: 4 to 5 percent of urea, 2 to 10 percent of humic acid, 2 to 10 percent of algae extract, 20 to 50 percent of calcium magnesium ore powder, 4 to 10 percent of iron powder, 0.5 to 2 percent of borax, and 15 to 30 percent of clay. The fertilizer is suitable to be used as a base fertilizer or early topdressing, generally 10 to 20 kilograms of fertilizer is applied in each mu, the fertilizer can be scattered or applied serially, ditch centralized strip application is better, and the fertilizer application depth is 8 to 15 centimeters.

Description

The manufacturing process of micro-composite granulated fertilizer in a kind of marine alga

Technical field

The present invention relates to micro-composite granulated fertilizer in a kind of marine alga, belong to the compound manure field.

Technical background

Content is that 0.1%~0.5% element is called moderate-element in the plant, comprises that calcium, magnesium, three kinds of constituent contents of sulphur are called trace element between the necessary nutritive element of 0.2~200mg/kg, and 7 kinds on zinc, boron, molybdenum, copper, iron, manganese, chlorine is arranged.Before chemical fertilizer industry is not come out as yet, the plant nutrition system is a kind of low-level material cycle, after 18th century, developed using of chemical fertilizer on the basis of application of organic fertilizers, over nearly more than 100 years, the amount of application of N, P, K chemical fertilizer sharply increases, and with crop take away in, micronutrient can not access the supply of system.

The experience of some developed countries points out that not only the nutritive element that crop should be taken away is given back soil from soil, but also should bring up to the highest level that adapts with plant physiology and economic system to soil fertility.

In, trace element is " enzyme " or the coenzyme that promotes photosynthesis, respiration and material transformation in the plant materials mostly " integral part.Very active in plant materials, when certain element in the soil was not enough, symptom can appear lacking in plant "; crop yield is reduced, and quality descends, when serious even No kernels or seeds are gathered, as in a year of scarcity; use corresponding fertilizer in this case, tend to receive very significantly the effect of increasing income one.

Summary of the invention

The objective of the invention is at the problems referred to above, composite a kind of middle micro-composite granulated fertilizer that contains marine alga, humic acids is to improve the physical condition of soil; Seaweed Extract contains natural active matter, and it can regulate the growth of plant, has stronger water retention; Lalgine has passivation to the heavy metal in the soil, stops crop to the absorption of heavy metal ion; Humic acids can change the chemical fertilizer characteristic; The structure of improving the soil; Stimulate the physiological metabolism of crop; Strengthen the crop adverse-resistant characteristic; Improve the sub-real mass of crop.

The present invention is achieved in that micro-composite granulated fertilizer in a kind of marine alga, belongs to the compound manure field.It is with natural wild or propagate treated its effective constituent of using of marine alga artificially, with handle through physics and chemical process contain in micro element mineral and humic-acid kind organic raw material, through concentrate, granulation process is mixed and forms.The weight percent of each component is: urea 4-5%, humic acids 2-10%, Seaweed Extract 2-10%, calcium magnesium slag 30-50%, iron powder 4-10%, borax 0.5-2%, clay 15-40%.

In the marine alga in the micro-composite granulated fertilizer effective constituent of each component be respectively: urea, available nitrogen (N) content 2%, organic effective constituent 1% in the humic acids, Seaweed Extract active substance 1%, calcium oxide in the calcium magnesium slag (CaO) effective content 8.1%, magnesium oxide (MgO) effective content 7%, ferric oxide (Fe in the iron powder 2O 3) effective content 2%, effective boron (Na in the borax 2B 4O 710H 2O) content 0.4%, calcium oxide in the clay (CaO) effective content 2.3%, magnesium oxide (MgO) effective content 3%.

Application process of the present invention is: this fertilizer is applicable to be made base manure or topdresses in early days, and general 10-20Kg/ mu spreads fertilizer over the fields, go here and there Shi Junke, and is better with the concentrated row replacement of ditch spread, fertilization depth 8-15cm.But do not contact with seed, seedling, so as not to " burning " plant, " burning " root.

Embodiment

Embodiment 1:

Material name weight percent (%) material name weight percent (%)

Urea 4 iron powders 8

Humic acids 5 boraxs 1

Seaweed Extract 5 clays 37

Calcium magnesium slag 40

Embodiment 2:

Material name weight percent (%) material name weight percent (%)

Urea 5 iron powders 6

Humic acids 8 boraxs 2

Seaweed Extract 8 clays 26

Calcium magnesium slag 45

Micro-composite granulated fertilizer has following advantage in the marine alga:

1. adopting calcium magnesium slag and clay to solve the problem of trace element during soil lacks as main raw material, is example with Zunhua, Hebei calcium magnesium slag and clay, and it comprises in calcium, magnesium, the iron etc., 25 kinds of trace elements, 15 kinds in rare earth element, count 40 kinds, and content is moderate, useful and harmless to farm crop.Solve soil with humic acids, Seaweed Extract etc. and lacked organic problem.They can increase soil aggregate, improve soil physical and chemical property, strengthen the soil fertilizer water retention capacity, are conducive to the crop root growth, make robust plant, early send out not wane.

2. Seaweed Extract contains natural active matter, and it can regulate the growth of plant, has stronger water retention; Lalgine has passivation to the heavy metal in the soil, stops crop to the absorption of heavy metal ion.

3. the humic acids function mainly contains: change the chemical fertilizer characteristic; The structure of improving the soil; Stimulate the physiological metabolism of crop; Strengthen the crop adverse-resistant characteristic; Improve the sub-real mass of crop.

Claims (3)
