Description
Technical field
The present invention relates to a kind of method preparing soil improvement agent, especially relate to a kind of method utilizing furfural dregs and furfural waste-water to prepare liquid soil improvement agent.
Background technology
At present, China is the country that Arid&semi-arid area area is bigger in the world, accounts for the 52.5% of the total land area in the whole nation, is mainly distributed in 15 provinces and regions of the northeast of northern China, North China and northwest, and arid area water resources shortage, ecotope is very fragile. In addition, there is more than 500,000,000 mu of saline and alkaline soil in China, and salt affected soil is unfavorable for plant-growth, seriously governs the output of agricultural-food. Simultaneously due to constant the using chemical fertilizer, agricultural chemicals, sterilant and irrational utilize soil of peasant household, global soil degenerate problem is day by day serious, so the task of improvement soil is extremely urgent.
In recent years, soil conditioner causes the attention of China professional of agriculture and peasant, and the various soil conditioner product of China emerges in an endless stream thereupon, is wherein divided into acidic soil conditioner, trophicity soil conditioner, organism soil conditioner etc. by character; The soil conditioner of control Soil degradation can be divided into by purposes, reduce the improvement soil conditioner etc. in the soil conditioner of heavy metal pollution of soil, saltings. But major part is solid state, there is fertilising uneven, mobility is poor, and the not high phenomenon of utilising efficiency, plays a role simultaneously and also need the participation of moisture, and especially at Arid&semi-arid area, water resources shortage, its utilization ratio is not high, it is very difficult to take effect.
A large amount of alkaline residues can be remained, wherein containing organic matter such as a large amount of humic acidss while production Water soluble fertilizer; Producing in the waste water after furfural, also containing a large amount of organic matter of humic acids, and it is in acid, and pH is about 3. Humic acids can improve soil, it is to increase the utilization ratio of chemical fertilizer, and stimulating plant grows, and strengthens the resistance of plant, and these functions such as resisting drought saving water.
Stacking and the furfural waste-water of these waste residues is not also utilized to develop a kind of for saltings and liquid soil conditioner arid, that semiarid soil is used so far.
Summary of the invention
It is an object of the invention to overcome the defect of prior art, it is provided that a kind of method is unique, have improve soil physico-chemical property, rehabilitating soil pollutes, improve the functions such as plant recovery of nutrient, Promoting plant growth, raising agricultural output, can be applicable to saltings, a kind of method utilizing furfural dregs and furfural waste-water to prepare liquid soil improvement agent in arid and semiarid soil.
The present invention realizes in the following way:
A kind of method utilizing furfural dregs and furfural waste-water to prepare liquid soil improvement agent, it is characterized in that: the method is for by raw material alkaline residue 22.9%��40.1%, furfural waste-water 33.3%��53.3%, urea 12%��15%, monoammonium phosphate 3.8%��9.6%, potassium sulfate 4%��6% adds in reactor successively, maintains the temperature at 40 DEG C��50 DEG C, fully stirring 1h��2h, the content of above-mentioned raw materials is weight percentage;
The preparation method of described alkaline residue is as follows:
A. ferment: by 70%��80% furfural dregs, 15%��20% agricultural crop straw and 5%��10% farm manure, after mixing, fermentation temperature canopy in carry out aerobic fermentation, leavening temperature controls at 45 DEG C��60 DEG C, adding furfural waste-water, make the moisture control of compound 40%��50%, temperature is elevated to after 50 DEG C��60 DEG C, mechanical turning in every two days is once, after fermentation of furfural residues becomes thoroughly decomposed, release from fermentation canopy, stack for subsequent use;
B. the preparation of alkaline residue: by the furfural dregs of above-mentioned 70%��90% fermentation maturity, concentration with 10%��30% is that 2%��4% potassium hydroxide solution is at 70 DEG C��90 DEG C mix and blend 1h��2h, filter supernatant liquor, obtain alkaline residue, organic matter such as the humic acids wherein contained after testing accounts for more than the 50% of the furfural dregs that becomes thoroughly decomposed, in alkalescence, pH value is 9 ~ 11, and the content of above-mentioned furfural dregs, potassium hydroxide solution is weight percentage;
Described furfural waste-water derives from the process utilizing corn cob production furfural;
Described urea, monoammonium phosphate, potassium sulfate is technical grade product;
The mixture of one or more of the ight soil of the behaviour of described farm manure and poultry;
Described agriculture stalk is pulverized corn cob, corn and wheat stalk.
The present invention has following effect:
1) this product is divided into Different Nutrition component prescription, can separately for soil conditioner, it is also possible to being that soil conditioner and base manure are same executes, and specifically according to the needs of user and can survey soil formula and determine.
2) can be applicable to saltings, arid and semiarid soil: method product design provided by the invention becomes different ingredients, its pH is also different, can use respectively according to soil situation, such as pH=6��7, can be used for arid respectively with pH=5��6, semiarid and saltings uses.
3) product application provided by the invention is in liquid manure integrated technique, reaches fertilising and executes water synchronous, fertilising can be made simultaneously even, and nutrient degree of mobilization is big, and plant easily absorbs, and saves labor force.
4) prove through a large amount of field test, utilize soil conditioner provided by the invention can improve agricultural output, quality of agricultural product and mouthfeel can be improved simultaneously.
5) soil physics structure is improved: utilize the soil conditioner that method provided by the invention is produced, containing the organic matter of a large amount of humic acidss. Humic acids is the structure person of soil granular, the coacervate of greater particle size in soil, the formation of microaggregate can be promoted, thus effectively reduce the soil weight, increase soil porosity, improve soil enzyme activity, make the performance enhancement that soil water-reataining fertilizer-keeping is ventilated, it is to increase soil fertility.
6) rehabilitating soil pollutes: humic acids belongs to natural organic high-molecular compound, has complexing heavy metal ability, therefore can pollute by repairing heavy metal in soil, avoids heavy metal simultaneously and enter in plant materials, and with food chain transfer, harm is to people and animals. So using the safety that soil conditioner provided by the invention can guarantee food from food source.
