Description
Technical field
The invention belongs to agrochemical field, be specifically related to a kind of multifunction soil conditioner and preparation method thereof.
Background technology
Along with deepening continuously of China's reform and opening-up, the paces of national urbanization process are accelerated, and agricultural effectively cultivated area has the trend that reduces gradually.Due to the growth of the size of population, to the also constantly increase of demand of agricultural-food, the grain imbalance between supply and demand becomes increasingly conspicuous.Agriculture production is for obtaining higher output, except implement adjusting pattern of farming, improving the measure such as arable land multiple crop index, also taked to use in a large number the method for chemical fertilizer and agricultural chemicals in cultivation, cause ploughing occur that in various degree acidifying, salinification, structure deteriorate, ventilation property is poor, degradation problem under nutrient imbalance, fertility.Add a large amount of three wastes that discharge due to industrial expansion, acid deposition is just adding the degeneration of heavy soil.Agroecological environment is constituted a serious threat, especially blindness and irrational fertilizer regime on facility cultivation special environment condition and behavior adjustment management utilize, cause soil physical and chemical property to worsen more serious, soil throughput is the gesture of decline, and then cause crop failure, degradation under agricultural product quality.
National contaminated arable land has accounted for more than 10% of total area under cultivation at present, reaches 1.5 hundred million mu." at present soil fail is not limited to some partial area, but the common problem of nationwide: the black soil of Northeast China organic content is just expanded to 65%, is reduced 5 centimetres during the overall survey of soil more for the second time of wheat crop rotation district, North China topsoil by 52% before 30 years less than 6.5 ratio with annual 2/1000ths decrease of speed, southern 14 provinces (district, city) soil pH ... so the soil conditioner of improvement soil physics, chemistry and biological property is extremely urgent.In addition, approximately 1,500,000,000 mu of the existing lack of water of China and seasonal drought areas are wherein to plough in drought and water shortage and slope more than 70%.What in addition, make the vast farmers headache most is up to 400,000,000 mu of acid soils and 2.5 hundred million mu of saline-alkali soils.For the different problems of different zones soil, the total area under cultivation that soil conditioner can play a role is 11.5 hundred million mu.
In order to solve soil compaction, chessom, the raising gas permeability of soil, to reduce the soil weight, promote soil microbial activities, strengthen soil rich water seepage force, has improvement soil, administer desert, water conservation anti-morning, strengthen the disease-resistant crops ability, improve crop yield, improve quality of agricultural product, the soil conditioner of the functions such as recovery crops original ecological receives much concern, and uses soil conditioner to improve soil regime and day by day is accepted.Soil conditioner is to be main raw material by agricultural water-loss reducer and the natural peat or other organism that are rich in organic matter, humic acid, being aided with bioactive ingredients and nutritive element forms, through the product that scientific technology processes, extremely significant " water conservation, getting fat, ventilative " three large soil conditioning performances are arranged.
But the development of domestic production soil conditioner still is in the starting stage.From domestic last century the mid-80 introduce soil conditioner, this industry has been passed by nearly 30 days, however nowadays 38 register manufacturing enterprise's scale and 2000, the whole nation and set foot in new-type fertilizer enterprise and compare, only account for 1.9%.Current manufacturing enterprise also fails to meet the need of market.The quality of existing soil conditioner is also uneven in addition.Mainly there is following problem:
1) the various standard that causes of raw material sources is had difficult labour
The same with the humic acid fertilizer, the chitin fertilizer that rose in recent years, various difficult labour that directly causes its GB of soil conditioner raw material sources.It is reported, current soil amendment raw material is mainly from ore, agriculture and industry waste, plant and animal residues three aspects:, wherein register product maximum derive from ore, account for 40.9% of whole registration product.All the other 50% from materials such as the alkaline residue that may contain objectionable impurities, food-processing industry waste liquid, shells, and also this part product causes that wherein effective constituent and heavy-metal residual can't be measured just.

There is the not good or incomplete problem of improved effect in single soil improvement agent, the macromolecular compound soil conditioner of synthetic has cost height and potential secondary environmental pollution risk simultaneously, and the improved effect of natural soil amendment is limited, and has the problem that the time length is short, consumption is large.
3) unreasonable abuse on the contrary can spoiled soil
Be not that soil conditioner can be used in all soils.Arbitrarily abuse can run counter to desire, and not only can not improve soil, can damage on the contrary.It is reported, according to the soil conditioner different efficacies, its scope of application is also different.In addition, some soil conditioner also is not suitable for life-time service, take the amendment product that contains sodium-ion type as example, if point out that life-time service easily causes soil pH value to raise, and then causes Soil structure to be destroyed.
Can have side effects with wrong soil conditioner and give no cause for much criticism, even if but use soil conditioner, if method is not to there is no too effect.Take applicable southern area Acid soil as example, the acidic soil conditioner product of capable of regulating soil pH should be take powdery as good, and common product needed just can take effect in 3-6 month action time, therefore must spread fertilizer over the fields in advance, " whether the amendment effect can be kept 2-3, mend and execute also and will decide according to soil regime ".
