Description
Technical field
The present invention relates to a kind of preparation method of compound organic fertilizer, and compound organic fertilizer prepared by the method, a kind of soil-repairing agent containing above-mentioned compound organic fertilizer, and the application of this soil-repairing agent in soil remediation, and the implantation methods of a kind of plant.
Background technology
At present, China degenerates in agricultural land in large area, harden and heavy metal, the degeneration of soil, to harden and heavy metal is that Fertilizer application falls the result more developed.
Use fertilizer the earliest.The use of fertilizer has comparatively long history in China, and peasant has a proverb: one, crops flower, complete main by excrement.The most important ring of agro-farming is collected manure exactly.For thousands of years, peasant cultivates by farmyard manure substantially, and present market fertilizer is generally divided into farm manure, green manure and humic acid fertilizer three class, and its feature is: nutrient kind is many, and concentration is low, and release is slow, but can only make substrate fertilizer.
Next is chemical fertilizer (being also mineral manure).After World War II terminates, in order to adapt to increasing rapidly of world population, application fertilizer becomes the effective measure of agricultural produce.China starts extensive use for 1963, and chemical fertilizer is generally divided into several large class of nitrogenous fertilizer, phosphate fertilizer, potash fertilizer, composite fertilizer, Chemical Mixed Fertilizer and trace element fertilizer according to its effective constituent.Its feature is: concentration is high, and release is fast.
Moreover be microorganism fertilizer, the Ministry of Agriculture started in 1996 microorganism fertilizer to be included in fertilizer registration category, and regulation microorganism fertilizer must carry out inspection registration in the Ministry of Agriculture, and it is bacterial fertilizer, being the organism lived, is played a role by the powerful decomposition of bacterium, reduction movable.The microorganism fertilizer of China have studied more than 10 year, does a lot of experiment, and achieves good achievement.Wherein a kind of experimental data of Herba Astragali Melilotoidis (Herba Astragali Sinici) of crying shows, and after using microorganism fertilizer, First Year increases production 60%-100%; Second Year volume increase 20%-60%; Volume increase 15%-40% in 3rd year; Volume increase 10% in 4th year.Microorganism fertilizer kind generally can be divided into: microorganism seed dressing agent, all kinds of rhizobia fertilizer; Composite microbe fertilizer; Wherein, composite microbe fertilizer contains bacteria fertilizer (rhizobia fertilizer, fixed nitrogen, phosphorus decomposing, solution potash fertilizer), unwrapping wire bacterial manure (antibiosis fertilizer), Mycophyta fertilizer (mycorrhizal fungi, mould fertilizer, yeast fertilizer) and photosynthetic bacterium fertilizer etc.Its feature is use at the initial stage, and crop is healthy and strong; High yield can be reached.
But, the long-term application of above-mentioned three kinds of fertilizer to Soil degradation, to harden and heavy metal creates great effect.First, in recent years, because people are in the feed of animal cultivation, employ all feeds additive, various microbiotic, cause the dangerous of animal excrement.And field crop all makes substrate fertilizer with fertilizer.Its result then causes severe contamination and the degeneration of soil, brings threat to the health of people.Secondly, because chemical fertilizer nutrient is single, after using, cause all kinds of nutrients ratio imbalance of soil; Farmland ecological environment is destroyed; Soil physical and chemical property severe exacerbation.Chemical fertilizer is to the pollution of agricultural-food the most strikingly vegetables and fruit, and main manifestations is: form nitrate at Crop after nitrogenous fertilizer, change into nitrite further, the nitrite of a large amount is the arch-criminal causing cancer.In addition, along with agriculturists are in recent years to soil Use out of range chemical fertilizer, its result then cause soil severe contamination, harden and degenerate.3rd, micro organism composite fertilizer, also known as full fertilizer, several years ago uses micro organism composite fertilizer effect good especially, because it is active alien species, original for soil species can be destroyed and even eliminate, but, after 3 to five years, soil just not long crop gradually, causes the gradually mistake of soil effect.
Therefore, in the face of present situations such as the large-area performance degradation in China agricultural land, hardening, heavy metals, a kind of renovation agent can repairing existing degenerated soil is badly in need of.
Summary of the invention
The object of the invention is the preparation method in order to provide a kind of compound organic fertilizer, and compound organic fertilizer prepared by the method, a kind of can the soil-repairing agent of rehabilitating soil preferably, and the application of this soil-repairing agent in soil remediation, with the implantation methods of a kind of plant, to improve the effect of soil, increase the output of soil, and then the output of raising crop, veterinary antibiotics etc., quality and resistance etc.
The present inventor finds under study for action, a kind of preparation method of compound organic fertilizer, and the method comprises: by fertilizer, aqueous ethanolic solution and oil mixing, contact more than 1 hour, described oil is edible oil, and this compound organic fertilizer can significantly improve the output of plant.In addition, the soil-repairing agent containing this compound organic fertilizer and natural water crystalline flour, can improve the effect of soil, increases the output of soil, and then improves the output of crop, veterinary antibiotics etc., quality and resistance.
Therefore, to achieve these goals, on the one hand, the invention provides a kind of preparation method of compound organic fertilizer, the method comprises: by fertilizer, aqueous ethanolic solution and oil mixing, contact more than 1 hour, described oil is edible oil.
Second aspect, present invention also offers the compound organic fertilizer that aforesaid method is obtained.
The third aspect, present invention also offers a kind of soil-repairing agent, and this soil-repairing agent contains above-mentioned compound organic fertilizer and natural water crystalline flour, and relative to the described compound organic fertilizer of 100 weight parts, the content of described natural water crystalline flour is 0.01-45 weight part.
Fourth aspect, present invention also offers the application of above-mentioned soil-repairing agent in soil remediation.
5th aspect, present invention also offers the implantation methods of a kind of plant, uses above-mentioned soil-repairing agent or use above-mentioned compound organic fertilizer in the method.
Compound organic fertilizer of the present invention can significantly improve the output of plant, and soil-repairing agent of the present invention can by coordinating the relation of moisture and nutrition, can provide for the plant in plant particularly adverse circumstance one perfect, harmonious rhizospheric environment, the quick growth of plant can be promoted, improve output and the fruit quality of crop, strengthen the resistance of plant, such as drought resisting, cold-resistant, disease-resistant and Saline alkali tolerance, therefore, soil-repairing agent of the present invention is not only applicable to common agricultural land, also be applicable to various saltings, degenerate and contaminated soil land used, and the Desertification of soil can be improved.In a word, soil-repairing agent of the present invention can play a role defending and controlling sand, in the innoxious and recycling treatment of soil improvement, ecological recovery, agricultural, forestry plantation (biasing toward cash crop), township afforestation and gardens construction, water-saving agriculture, establishment of economic forest, the greening of territory, highway and railway road, town and country organic waste etc.
Other features and advantages of the present invention are described in detail in embodiment part subsequently.
