Description
Technical field
The present invention relates to farm-forestry crop field of planting, and in particular to a kind of water keeping fertilizer and its system using manioc waste preparation
Preparation Method.
Background technology
China is a large agricultural country, and agricultural water accounts for 80% or more of China's total water consumption, and the shortage of water resource is system
Therefore the about first cause of China's agricultural development improves the utilization rate of agricultural water resources.It is China's agriculture to implement saving water, resisting drought technology
The important channel of industry sustainable development.In China, arid and semi-arid lands's proportion reaches 50% or more of national territorial area, and
The moisture holding capacity of soil is relatively low, and is easy evaporation, and the availability of moisture itself is low, thus Arid Problem has become puzzlement China
The a great problem of agriculture and forestry.
With the getting worse of environmental pollution and the reduction year by year of green vegetation, sternness is proposed to environment for human survival
Test, the especially fields such as agricultural production and urban afforestation, soil moisture be easy to run off, and causes soil block, soil
The problems such as desertification, therefore how rainwater or watering pours water to be absorbed and be kept rapidly in the soil, not permeable mistake, and then ensure plant
It is grown to serve as important research direction.
The big province that Guangxi is produced as a cassava, annual cassava usage amount is all being continuously increased, but is being produced simultaneously
Waste residue-the manioc waste generated in the process is also being continuously increased.Manioc waste is that cassava is squeezing starch or alcohol by starch factory
Factory produces alcohol waste left later, but still contains abundant cellulose, hemicellulose, starch and inorganic salts etc.
Substance is a kind of highly useful biomass sources.For now, there are mainly three types of methods for the processing of manioc waste, respectively detest
Aerobe fermentation produces biogas, fermenting and producing alcohol and production feed.But these three processing methods all fail general for various reasons
And application, a large amount of manioc waste is also in discarded state.
In recent years, water-retaining agent is as a kind of NEW TYPE OF COMPOSITE auxiliary agent that can effectively enhance soil water holding capacity and moisture holding capacity,
The fields such as soil structure improved addictive, agricultural water conservation drought resisting achieve many impressive progresses.There are many current existing water-retaining agent type, but
It is the effect being usually only retained, does not improve the effect of soil, and not degradable, long-term existence causes soil hardening, unfavorable
In the sustainable development of ecological environment and planting.Therefore, a kind of efficiently being prepared using manioc waste for low cost is developed
Water keeping fertilizer, have higher market value.

Potassium element is provided.
3. the water keeping fertilizer of the present invention prepared using manioc waste, addition manioc waste charcoal, biogas residue, nitrogenous fertilizer, phosphate fertilizer, potassium
Fertilizer and complex micro organism fungicide, disclosure satisfy that the different nutritional need of plant, and can improve soil texture and enhancing soil water-retaining,
The ability of fertilizer conservation.
Manioc waste charcoal has stronger adsorption capacity, can improve the water absorbing capacity of fertilizer, reduces fertilizer loss, carries
High usage；On the other hand, also seek a new approach for the application of manioc waste, improve the utilization rate of manioc waste.
Biogas residue is a kind of particular matter containing fertilizer, biological pesticide and feed addictive function, containing many nutrition at
Point and bioactive substance, can not only improve soil physical and chemical property, increase fertility, moreover it is possible to significantly improve crop yield, to
Improve the fertility of water keeping fertilizer.
Bacillus subtilis and Trichoderma are added, can inhibit and killing causes the rotten seedling stem rot of dead of plant, root rot
Pathogen.Actinomyces are added, worm substance and parasitization inhibition nematode egg hatching are pressed down by secretion and kill nematode.Addition is solid
Nitrogen, phosphorus decomposing and the various mushrooms of potassium decomposing, the nutrients such as fixed nitrogen, phosphorus, potassium in effective fertilized soil, improve chemical fertilizer utilization ratio
10% or more, reduce fertilizer application amount.Addition saccharomycete can improve soil texture, and activating soil improves the gas permeability of soil, training
Fertile soil fertility.
4. the water keeping fertilizer of the present invention prepared using manioc waste, adds the trace element of aminoacid chelate.Nothing
The trace element of machine salt form, utilization rate is easily influenced by pH value, fiber, oxalic acid, vitamin, phosphoric acid and phytic acid etc., and ammonia
For the trace element of base acid chelate due to its stable chemical performance, intramolecular charge tends to be neutral, can in vivo under pH value
It effectively prevent trace element ion to form undissolved compound, or it is prevented to be attracted to the insoluble dispergation for hindering element absorption
On body, thus be conducive to body absorption.Numerous studies show that the absorption of trace elements rate through chelating amino acids is inorganic micro member
2~6 times of element.Simultaneously chelate element can effectively avoid added in feed caused by excessive inorganic elements be poisoned and waste
Phenomenon, and it can effectively be released when body needs, to meet body needs.
5. the preparation method for the water keeping fertilizer of the present invention prepared using manioc waste, the glycerine for using low toxicity cheap is friendship
Join agent, different from the N-N methylene-bisacrylamides (MBA) being commonly used, water-retaining agent cost reduction, while reducing environment
Pollution.The preparation method, it is simple for process, it is with obvious effects, it is easy to industrialized production, there are good market prospects.
