Description
Technical field
The invention belongs to the Reducing amount of chemical fertilizer applied Synergistic technique fields of planting industry source agricultural non-point source pollution prevention, and in particular to a kind of
Soil Nitrogen, the modification biological charcoal and its preparation method and application of phosphorus absorption property can be improved.
Background technology
China's fertilizer amount in 2014 reaches 60,000,000 tons, and unit cultivated area fertilizer amount is the 3 of world average level
Times, but this season utilization rate of nitrogen fertilizer is about 30%~35%, and phosphate fertilizer utilization efficiency is only 10%~25%, well below developed country's water
It is flat.Long-term excessive chemical fertilizer of applying causes a large amount of accumulations of arable soil available nitrogen, phosphorus.According to《Delta of the Pearl River cultivated-land
Investigation and quality evaluation》Achievement Report, Delta of the Pearl River arable soil nitrate nitrogen, available phosphorus content generally belong to abundant level.
However, as the surplus in arable soil active nitrogen, phosphorus storehouse is constantly soaring, nitrogen, phosphorus loss also constantly increase.《Guangdong Province
Once national Pollutant source investigation publication》The results show that 6.64 ten thousand tons of the total nitrogen number of dropouts of planting industry, total phosphorus number of dropouts 0.74 ten thousand
Ton.Currently, agricultural non-point source pollution problem becomes increasingly conspicuous caused by planting industry nitrogen, phosphorous loss, it has also become influences ecological environment peace
Entirely, an important factor for health.
Nitrogen, phosphorus element loss caused by planting industry source agricultural non-point source pollution problem be increasingly subject to the extensive passes of countries in the world
Note, control measure is just actively studied by various countries since the 1980s.From control planting industry source nitrogen, phosphorus pollution of area source research into
From the point of view of fruit, first, by policy and legislative means, macro-control is with reducing the nitrogen after nitrogen, phosphate fertilizer input amount and crop harvest, phosphorus
Fertile residual quantity；Second is that by improving agriculture production technology or development environment friendly product, realize that farmland nitrogen, phosphate fertilizer are rationally thrown
Enter, improve nitrogen, phosphate fertilizer utilization efficiency, reduce the various approach losses of nitrogen, phosphate fertilizer.In recent years, using low economic value or without economy
The rural area biomass castoff of value prepares charcoal, and charcoal is reduced planting industry nitrogen, phosphorus element stream as soil conditioner
The research of mistake is increasing.Substantial amounts of research, which shows that charcoal matches somebody with somebody to apply with chemical fertilizer, can reduce applying quantity of chemical fertilizer, improve nitrogen, phosphate fertilizer
Utilization rate reduces nitrogen, phosphorous loss.Consider from recycling angle, exploitation charcoal replacing fertilizer technology is highly
The Reducing amount of chemical fertilizer applied augmentation strategies of trial.However, charcoal is complex to the influencing mechanism of Soil Nitrogen, phosphorus storehouse dynamic change,
Application effect may be related with the factors such as soil types, charcoal property and its amount of application.Plantation is reduced in order to enhance charcoal
The application effect of industry nitrogen, phosphorous loss, some domestic and international researchers are modified charcoal processing, such as Li Jihui 2012
《Chinese agriculture is meteorological》33(2)：Delivered on 220-225 " suction-operated of modification biological charcoal and its to soil nitrate-N and
The side for being loaded to iron-containing metallic compound and modification biological charcoal being prepared on charcoal is proposed in the influence of available phosphorus leaching loss "
Method, i.e. (1) take the unmodified charcoals of 100g (raw material of charcoal is crop material) to be soaked in the hydrochloric acid that 1L contents are 1mol/L
1h in solution；(2) elution to leacheate is neutrality, and by the drying of 75 DEG C of charcoal；(3) immersion of different quality is taken to dry respectively
Charcoal afterwards is positioned over FeCl3In solution, solution alkaline is adjusted, be uniformly mixed and stands 1h；(4) distilled water filter 23 is used
It is secondary, last 75 DEG C of drying.Optimal iron modification biological charcoal after this method of modifying prepares and is preferred greatly strengthens charcoal suction
The ability of attached nitrate nitrogen and titanium pigment delays and reduces the leaching loss of nitrate nitrogen and titanium pigment in native fish experiment, but
It is cumbersome, expensive, it is difficult to be promoted and applied in field experiment.How to develop that step is simple, of low cost, effect is good
Good iron modification biological charcoal preparation method and the modification biological charcoal base soil conditioner that can be promoted and applied be still from now on chemical fertilizer subtract
Measure one of research and development and the application hot spot in Synergistic technique field.

Respectively processing cell and the Guan Zhongtie that fetches earth are modified water hyacinth charcoal and applying quantity of chemical fertilizer to table 4
2 pipes that fetch earth respectively are squeezed into each anchor point, fertilizer is applied in proportion in pipe and pipe is outer, wherein 1 pipe that fetches earth
(seal pipe) is sealed to avoid loss, and it is consistent with natural conditions variation that another 1 pipe that fetches earth (open tube) allows it to open wide, and cultivates 70 days
Afterwards, two pipes that fetch earth for installing soil are taken away, takes back lab analysis Soil Nitrogen, phosphorus situation.Soil nitrogen leaching volatilization denitrification damage
Vector=seal pipe various nitrogen forms amount-open tube various nitrogen forms amount；Soil Nitrogen cut rate=(habits fertilization handles various nitrogen forms
Loss-plus the loss of iron modification biological charcoal processing various nitrogen forms)/habits fertilization processing various nitrogen forms loss × 100%.Soil phophorus
Leaching loss amount=seal pipe available phosphorus amount-open tube available phosphorus amount；Soil available phosphorus cut rate=(habits fertilization processing has
Effect phosphorus loses-adds the loss of charcoal processing available phosphorus)/habits fertilization processing available phosphorus loss × 100%.Result of the test such as table 5
It is shown.
Table 5 fetches earth the calculating of nitrogen, phosphorus loss amount and cut rate in pipe
