Description
Technical field
The present invention relates to a kind of organic fertilizer prepared as raw material with charcoal and marine alga.
Background technology
Worldwide aquaculture, planting industry promote dynamic plant mostly by means of chemical classes antibiotic, growth regulator, agricultural chemicals etc.
Growth, prevention plant epidemic disease of thing etc., although effect substantially, but often causes agrochemical to remain exceeded, environmental pollution
Etc. adverse consequences, the qualitative effects to crops are also very big.It is especially excessive to apply chemical fertilizer of simple substance such as nitrogen manure, make soil plate
Knot aggravation, soil fertility declines, and the need for making the quality of crop products and nutrition be difficult to meet people, green food is not reached more
The requirement of product, and cause serious environmental pollution.
Alga fertilizer belongs to natural seaweed extract, harmless to people, animal, environmentally safe, and organic food is put into abroad
Production dedicated fertilizer, is natural, efficient, new organic fertilizer.Contain algal polysaccharides, phenols, heteropolymer, sweet dew in marine alga
The element such as alcohol, glycine betaine, alginic acid, plant growth regulating substance and nitrogen, phosphorus, potassium and iron, boron, molybdenum, iodine, rather than chemical synthesis,
It is harmless to people, animal, after large area use, the pollution to environment can be substantially reduced, can reach green nothing with its agricultural product planted
The standard of public hazards.Therefore, alga fertilizer complies fully with Trends for modern agricultural development, and the market space is boundless.At present, alga fertilizer etc.
Natural organic fertilizer material is widely used in developed countries and regions such as America and Europes, and in progressively replacing fertilizer.
Alga fertilizer has bioactivity very high, and few consumption can stimulate plant growth, increase the nutrition of agricultural product
Component content and sugar content, improve yield, improve local flavor, color and luster and the resistant storage properties of fruit.Alga fertilizer can improve in many-side
The health status of crop, meets crop to some micro- particular/special requirements, the effectively physiological disease of preventing and treating plant, and raising is made
The cold-resistant of thing, drought resisting, anti-adversity ability.Alga fertilizer can also play an important role on protecting agriculture ecological environment, self-restraint soil.Its
The spontaneous growth Auto-regulator for containing, it is easy to which plant absorption conducts, chronic administration can directly make the soil (or make soil by plant
Increase organic matter) activation soil in various beneficial microbes, making the biopotency of soil increases.In addition, it contain it is natural
Compound such as Sodium Alginate is natural soil regulator, can promote the formation of soil granular structure, improves soil internal void empty
Between, coordinate solid, liquid, gas proportions in soil, can recover due to soil that over-burden and chemical contamination and the natural gum that loses
Matter is balanced, and soil is ventilated more preferable, and root system of plant is deeper, increases geobiont activity, increases the release of available nutrient, is improved and is made
The resistance of thing, sets up optimal plant-soil ecosystem.Therefore, alga fertilizer can make up China as novel organic fertilizer material
The deficiency of traditional organic fertilizer, the sustainable development to agricultural provides sound assurance, significant to improving the ecological environment.
The marine algae resource that the only large-scale economical alga of China just has the coastal areas such as kind more than 100, Yantai, Weihai, Qingdao is even more
It is abundant, wherein being no lack of the seaweed species for having fertilizer efficiency high.Additionally, the marine alga such as the coastal area such as Yantai, Weihai, Qingdao Enteromorpha in recent years
Spread unchecked, severe contamination environment even more influences coastal landscape.
At present, overwhelming majority producer mainly produces alga fertilizer using chemical hydrolysis both at home and abroad, i.e., existed using strong acid, highly basic
Marine alga is processed under the drastic conditions of HTHP, this method technique is complex, condition is harsh, and destroys sea
Substantial amounts of active ingredient in algae.In addition, there is not yet the compoundings such as marine alga and charcoal to be prepared the report of organic fertilizer.
The content of the invention
