Description
Technical field
The invention belongs to soil remediation field, more particularly to a kind of administering method of acidified soil.
Background technology
China industry fast development, result in the appearance of acid deposition problem, research shows, south China have become after
The third-largest acid deposition area after America and Europe, the appearance of acid deposition problem, causes the generation of soil acidification, field and laboratory experiment are all
Show, in the past few decades, acid deposition result in the acidifying of Chinese soil large area, and soil acidification refers to that soil absorption is compound
Body receives certain amount exchangeable hydrogen ion or aluminium ion, makes the process of soil neutral and alkali ion leaching loss.Soil acidification can be led
Cause pH value to reduce, form acid soil, influence activity biological in soil, change the form of nutrient in soil, reduce nutrient
Validity, promote free manganese, aluminium ion to dissolve in the soil liquid, toxic action is produced to crop.
General conventional method is to improve acidified soil using quick lime or gypsum, although using quick lime or gypsum
Cost is cheap, but easily causes soil hardening.For being acidified serious soil, the main function using quick lime or gypsum is
The influence of the acidity, elimination activity iron of sweetening of the soil.The shortcomings that the method is：（1）Soil hardening is caused, mainly due to raw stone
Ash can form a large amount of compounds not soluble in water after entering soil, and it causes to harden after in soil assembling, be hardened；（2）Cause
Crop lacks nutrient, and soil hardening causes crop root absorbability to decline, influences its suction to nutrients such as potassium, phosphorus
Receive；（3）With the increase of farming time, soil acidification phenomenon can occur again, that is to say, that not tackle the problem at its root.
Also there are some new methods using microorganism formulation etc., but cost height be present, and microorganism may be not easy to deposit
The problems such as living.Current existing soil conditioner is mostly synergy, promotes plant absorption nutrition, the effect of improvement soil hardening, and right
Technology is ripe not enough in improve soil acidification the problems such as.
The content of the invention
The technical problems to be solved by the invention：For in current acidified soil governance process, easily causing soil hardening
Problem, the invention provides a kind of administering method of acidified soil.
In order to solve the above technical problems, the present invention is using technical scheme as described below：
A kind of administering method of acidified soil, the administering method comprise the following steps：
（1）Acidified soil is turned over, irrigated using slaughtering wastewater to the soil after turning over, until the soil after turning over
Water content be 75~80%, use cogongrass mulching soil；
（2）After covering terminates, cogongrass is removed, soil is compacted using compacting machine, water is excavated on soil after compaction
Road, spacing is 30~50cm between each water channel, inserts hollow pipe between two water channels, nutrient solution is filled into water channel, is stood；
（3）After standing terminates, with 0.8m3/ h carries out into soil logical oxygen by hollow pipe, every time logical oxygen 20~
30min, stop 6~8h, repeat 7~9 times；
（4）After repeating to terminate, to the after-applied additive of soil, ploughing is carried out, shines ground 18~20 days, holding soil water content is
45~50%, that is, complete the improvement of acidified soil.
The step（2）The preparation method of middle nutrient solution comprises the following steps：
A. count in parts by weight, take 80~85 parts of water, 30~35 parts of peptones, 10~15 parts of manganese nitrates, 3~6 parts of compound sodium nitrophenolates
And 1~3 part of chlorophyll stirs, stirring mixture is collected；
B. using sodium hydroxide solution regulation stirring mixture pH to 7.5~8.0, diethanol amine is added, addition is stirring
The 3~5% of mixture quality, it is well mixed, produces nutrient solution.
The step（4）It is in mass ratio 4 that middle additive, which is,：1~3, cobblestone, diatomite are well mixed, you can, add
The applied amount for adding thing is every mu of 40~50kg.
Compared with other method, advantageous effects are the present invention：
The present invention is pre-processed using the nutriment and microorganism enriched in slaughtering wastewater to acidified soil, useless due to butchering
Microbiological resistance in water is strong, can adapt to the environment in acidified soil more by force, living so as to improve the biology in acidified soil
Property, recycling the mode of covering makes microorganism inside soil carry out fermentation process, adds the micro organism quantity in soil, simultaneously
Soil and hydrogen ion or aluminum ions combination are reduced using the activity of microorganism, and then improves the alkali ion in soil, is applicable
Nutrient solution further stimulates the existence of microorganism, improves adaptability of the microorganism in acidified soil, and subsequent use is oxygenated,
On the one hand the dissolved oxygen amount in soil is improved, on the other hand necessary oxygen demand is provided for microorganism, increases aerobic strain number, is utilized
The activity of aerobic strain increase soil, promotes the absorption to nutriment, while increases additive, by additive in soil
The processing of water, increase the activity of water, improve the self-adjusting ability of water, so as to reach the purpose for administering acidified soil, reduce and control
Occurs the problem of soil hardening during reason.
