Description
Technical field
The invention belongs to technical field of improving the soil, particularly relate to a kind of red soil orderly improvement method of shallow root system crop growing spots.
Background technology
At present, the patent about soil improving agent is more, but most soil improving agent material is not clear, and it is inadequate to there are raw material sources
Abundant, the shortcomings such as improving soil is the most lasting.As Jiangxi Institute of Red Soil Huang owe as wait invention " a kind of Upland Red Soil
Deacidification moisture control method " (patent No. 2012105189044, publication date on March 20th, 2013), spread fertilizer over the fields alkali to Upland Red Soil
Property deacidification damping composite modifying agent mulching straw, deacidification and damping effect can be produced, moreover it is possible to provide calcium, magnesium nutrition simultaneously,
Improve resource utilization, promote agricultural production and income；Remaining " the changing of a kind of gleying rice soil in rice district along the lake liking elementary invention
Good recipe method " (number of patent application 2013102019972, publication date JIUYUE in 2013 11 days), spread fertilizer over the fields alkalescence composite modifying agent,
Significantly reduce Soil gleyization, promote increasing production of rice, improve the soil organism and Available N-P potassium content.
Summary of the invention
The technical problem to be solved in the present invention is to provide one, and to improve the soil that raw material sources are wide, operating process is simple, target is adjustable controlled
And the red soil orderly improvement method of notable, comprehensive, the lasting shallow root system crop growing spots of effect.
For solve above-mentioned technical problem, the present invention by the following technical solutions: the red soil orderly improvement of shallow root system crop growing spots
Method, uses quick lime, (harmful substance contents such as heavy metal meets relevant for material of improving the soil for become thoroughly decomposed manioc waste and feces of livestock and poultry
Standard), carry out red soil orderly improvement by predetermined acid-base value and content of organic matter Breeding objectives.
Shallow root system crop growing spots is the Caulis Sacchari sinensis of tropical and subtropical zone red soil, Maninot esculenta crantz., Semen Maydis, Oryza sativa L., vegetables flake.
The weight ratio of manioc waste and feces of livestock and poultry of becoming thoroughly decomposed is 1:1.
The red soil orderly improvement method of above-mentioned shallow root system crop growing spots, is carried out by following operation: first measure red soil unit weight,
Acid-base value, the content of organic matter and become thoroughly decomposed manioc waste and the content of organic matter of feces of livestock and poultry mixture, determine the soda acid after improving the soil
Degree and content of organic matter desired value；Then, according to red soil acid-base value and content of organic matter initial value and the organic matter of material of improving the soil
Content, is determined the addition of various material of improving the soil respectively, puts down in conjunction with the soil of 20 centimetres by acid-base neutralization experiment and formula
All unit weight extrapolates the material usage of improving the soil of per hectare；Then, material of improving the soil uniformly is spread on Red Soil Surface, by 20 centimetres
The degree of depth turn over after fully rake even.
The problem existed for the improvement of current red soil, inventor establishes the red soil orderly improvement of a kind of shallow root system crop growing spots
Method, uses quick lime, becomes thoroughly decomposed manioc waste and feces of livestock and poultry is material of improving the soil, change by predetermined acid-base value and the content of organic matter
Good target carries out red soil orderly improvement.The method have improve the soil abundant raw material source and collect convenient, process operation of improving the soil is simple,
That target is adjustable is controlled, effect notable, comprehensively, the advantage such as persistently, can be widely applied to the Caulis Sacchari sinensis of tropical and subtropical zone red soil, wood
The shallow root system crop growing spots such as potato, Semen Maydis, Oryza sativa L., vegetable, make red soil be more suitable for the growth of shallow root system crop.Its work is former
Manage as follows:
<1>quick lime enters soil, becomes calcium hydroxide after water suction, and energy sweetening of the soil is acid, improves pH value, thus improves
Soil nutrient availability, become thoroughly decomposed manioc waste and feces of livestock and poultry mixture less negligible on the impact of soil acidity or alkalinity.
<2>become thoroughly decomposed manioc waste, feces of livestock and poultry is the more loose organic raw material of improving the soil of ratio, and the content of organic matter is high, has reduction soil
Earth unit weight thus improve the effect of soil hardening phenomenon, manioc waste granule is relatively thick, can increase the waterstable aggregate of 0.25 millimeter
Body quantity thus reduce liquid manure run off, organic matter can be supplemented, possibly together with a small amount of a large amount of nutrients and more middle trace element,
Variation of Integrated Soil Fertility can be improved.
<3>crop root such as Caulis Sacchari sinensis, Maninot esculenta crantz., Semen Maydis, Oryza sativa L., vegetable is shallower, generally in 20 cm range, and plow harrow
The degree of depth is the most also 20 cm, so calculate the soil gross weight of per hectare by the soil volume-weighted average of 20 centimetres, enters
One step calculates the soil improving agent consumption of per hectare soil, and its reasoning, calculating, implementation process are rational.
Practice have shown that, the method can be effectively improved red soil hardening, acidification phenomenon, shows that the soil weight reduces, more than 0.25
The water-stable aggregate quantity of millimeter and the content of organic matter increase, acid-base value improves, and supplement big, middle and trace element content,
Thus improve red soil comprehensive fertility and crop yield, quality.
Detailed description of the invention
In sugarcane trial base, Xixiangtang District, Nanning City Guangxi Academy of Agricultural Sciences, have a piece of red soil ground, soil compaction, viscous, acid,
Content of organic matter trace element deficiency low, middle, Sugarcane growth is poor, and application is the present invention improve the soil, and process of specifically improving the soil is as follows:
1, the harmful substance contents such as heavy metal, escherichia coli is selected to meet the Maninot esculenta crantz. processing waste Maninot esculenta crantz. of becoming thoroughly decomposed of national standard
Skin and cattle manure, measure its content of organic matter and be respectively 33%, 57%, by Maninot esculenta crantz. skin: the weight ratio of cattle manure is that 1:1 mixing is stand-by.
2, the average volume density measuring 0-20 centimetre of soil is 1.4t/m3, pH value 6.1, organic 2.1%.According to unit weight
The red soil gross weight calculating 20 centimetres of degree of depth of per hectare is 2800t.
3, under bright day gas, take 1 kilogram of soil, be put in Plastic Drum, add 5 kilograms of distilled water, after stirring
Add quick lime, measure and regulate aqueous solution acid-base value and arrive desired value 6.5, write down the average quick lime repeating experiment 3 times
Consumption is 0.5 gram, and the quick lime consumption that extrapolating per hectare soil needs is 1.4t.
4, extrapolate per hectare red soil and the content of organic matter is brought up to desired value 2.5%, the Maninot esculenta crantz. skin that becomes thoroughly decomposed that needs to add,
Cattle manure amount of mixture is 24.9t.
5, material of the phase application amount calculated being improved the soil uniformly is spread on Red Soil Surface, after turning over by the degree of depth of 20 centimetres fully
Harrow even.
This plot grows cane after improving the soil, and achieves preferable effect, and the soil weight is reduced to 1.32t/m3, pH value improves extremely
6.48, sugarcane yield improves 8%, and sugar improves 5%.
