Abstract
The invention relates to an oligo-alginate fertilizer and fertilizer efficiency thereof. The alginate is degraded into low-molecular weight oligo-alginate to be independently prepared into an alginate fertilizer, or is prepared into a compound fertilizer with one or more of macro and/or trace elements. The alginic acid in the alginate fertilizer has the advantages of low molecular weight, higher activity and the molecular weight of between about 1,500 and 3,000. The fertilizer efficiency test results prove that: the oligo-alginate is more convenient to be absorbed and utilized by crops, obviously accelerates the growth of the crops and has high activity; and the compound fertilizer can effectively improve the fertilizer efficiency, improve the root system activity, accelerate the root system growth, and improve the crop yield.
Description
Technical field
The present invention relates to fertilizer field, is the fertile research of a kind of low molecular weight seaweed acid specifically.
Technical background
Excessively use for a long time chemical fertilizer and made the physics and chemistry form of farmland ecological environment, soil and edaphon be subject to destruction in various degree, very large on the quality impact of agricultural-food.Seaweed fertilizer is take natural seaweed as raw material, through special physiological biochemical process means, extracts the elite material in the marine alga, produces the dissolved fertilizer that contains Lalgine, comprises algae essence concentrated solution, algae essence pulvis etc.Seaweed fertilizer is to produce another desirable fertilizer nuisanceless, green, Organic food behind organic fertilizer, bio-feritlizer.
Along with the development of China's rural economy and to the attention of green environment, it is imperative to develop new and effective fertilizer.Seaweed fertilizer belongs to natural product, and is nontoxic, harmless, pollution-free, and convenient transportation is used simply, and the effective constituent absorption rate is high, and crop and soil without any harm, are played significant adjusting and promoter action to plant-growth, is the first-selected fertilizer of green food.Seaweed fertilizer contains very abundant material composition, and it can help plant to set up healthy and strong powerful root system, promotes plant absorbing soil nutrient, moisture and gas; Can increase the vascular bundle cell of plant haulm, accelerate the transportation of water, nutrient and photosynthate, can promote plant cell division; Postpone cell aging, increase chlorophyll content of plant, the Effective Raise photosynthetic efficiency improves output, improves quality, strengthens the multiple degeneration-resistant functions such as crop drought resistance, cold-resistant, Resistant; Can also improve Soil structure, improve retention capacity of soil etc.
Alginate fertilizer is used widely as a kind of agricultural fertilizer, Chinese patent (the patent No.: the CN 1569755A) preparation method of stress-resistant seaweed fertilizer for example, Chinese patent (the patent No.: CN 1229778A) a kind of production method of fertilizers, Chinese patent (the patent No.: CN 101485343A) preparation method of Enteromorpha seaweed fertilizer etc., the Lalgine that these methods are extracted is the Lalgine of macromolecule, and molecular weight is generally between 10-60 ten thousand.The existing widely research of oligose Lalgine after the degraded (herbal cuisine) aspect medicine (medicine and medicament protection agent etc.), food; the application of agriculture field; United States Patent (USP) (the patent No.: US6117815) disclose the Lalgine of a kind of molecular weight between 6400-40000 as plant growth agent; application effect is better on paddy rice and peanut; in amount of increase in production on the paddy rice between 10-23%; the maximum amount of increase in production of peanut is 60%, and visible low-molecular-weight Lalgine is used in agricultural good prospect.
