Abstract
The invention discloses an acid soil improvement method, which includes the following steps: (A) calcium carbonate and calcium hydroxide are respectively ground by a fineness of 80 to 100 percent through a 20-40 mesh sieve, and thereby finely ground calcium carbonate powder and calcium hydroxide powder are respectively obtained; (B) the finely ground calcium carbonate powder and calcium hydroxide powder are uniformly mixed according to the weight ratio of 3:0.8-1.2, so that acid soil improver is prepared; (C) before soil preparation, the acid soil improver is evenly applied onto surface soil and then is uniformly turned into soil of a plough layer; (D) the dosage of the acid soil improver is 3500kg to 4000kg per hectare. The method is easy to practice, operation is simple and convenient, the materials of the acid soil improver can be easily obtained, the cost is low, moreover, the pH of acid soil can be increased to a range suitable for the growth of crops in a short time, after being used for about 30d, the acid soil improver can increase the pH of the soil of the entire plough layer from 4.0 to a range from 6.0 to 6.5, so that the survival rate of crops can be greatly increased, and therefore the method is worth popularizing.
Description
Technical field
The invention belongs to acidified soil and administer and the recovery technique field, be specifically related to a kind of method of acid soil improvement, be applicable to various quality acidified soil.
Background technology
Soil acidification is a kind of form of expression of soil degradation, refers to that soil acidification increases, and becomes a kind of natural phenomena of highly acid or extremely strong acidity.China's soil acidification situation is more and more serious, the land area of acidifying has expanded more than 40% of China's arable area to, and the situation of generation in blocks often arranged, particularly at south China, due to the slant acidity of soil own, rainwater is many again, and the soil acidification phenomenon is more serious, and the soil acidification of Wuhan Area or severe acidification are approximately more than 90%.The vegetable fields cropping index is high, and rate of fertilizer is large, uses physiological phenomenon fertilizer more, the acidifying problem of horticultural vegetable field soil is more outstanding than general arable land, and soil acidification causes plant recovery of nutrient to reduce, and harmful germ increases soil, directly affect the yield and quality of vegetables, and the sustainable development of vegetable field.
The method of tradition acid soil improvement is to use separately lime or limestone powder, and liming can make the acidity of acid ground reduce significantly, but makes sometimes multiple acidizing degree strengthen.Also have some acid ground composite modifying agents on market, main component is the mixture of lime and some mineral or industry byproduct, but the great majority in these modifying agents contain a certain amount of toxic metals element, as lead, cadmium, arsenic, chromium etc., exist the pollution problem to soil environment.
Summary of the invention
The objective of the invention is to be to provide a kind of method of acid soil improvement, the method is simple, handled easily, acid modifying agent raw material is easy to get, with low cost, and can in the short time, the pH of acid ground be increased to the scope of suitable plant growth, 30d of the present invention left and right can be increased to 6.0～6.5 from 4.0 by the soil pH of whole topsoil, greatly improve the survival rate of crop, be worthy to be popularized.
To achieve these goals, the present invention adopts following technical measures:
The invention solves the problem that current acid soil improving agent exists, adopt long-acting raw material calcium carbonate and quick-acting feed hydrogen calcium oxide to mix by a certain percentage, can play the effect for the treatment of both principal and secondary aspect of disease, by turning over, mix, can be improved whole plough horizon (0-20cm), and can not introduced toxic metals element pollution soil.The 30d left and right can be increased to the pH of topsoil the scope (6.0-6.5) of suitable plant growth from utmost point acid condition (4.0),
A kind of method of acid soil improvement, the steps include:
A, calcium carbonate and slaked lime are ground respectively, fineness requirement 80%-100% is by the 20-40 mesh sieve, obtains respectively a kind of calcium carbonate and slaked lime powder after levigate;
B, levigate calcium carbonate and slaked lime powder are fully mixed according to weight ratio 3:0.8-1.2, make acid soil improving agent;
Before C, whole ground, the acid soil improving agent uniform surface is imposed on to upper soll layer, then turn over and sneak in topsoil (0-20cm) soil, and guarantee evenly;
D, acid soil improving agent Optimum are per hectare 3500-4000kg.
Described acid soil improving agent was used once every 2～3 years.
The present invention compared with prior art, has the following advantages and effect:
The invention solves the problem that acid soil improving agent exists in the market, adopt long-acting raw material calcium carbonate and quick-acting feed hydrogen calcium oxide to mix by a certain percentage, by turning over, soil conditioner is sneaked into to whole topsoil soils (0-20cm), soil to whole plow layer is improved, reduce the generation of multiple acidifying problem, can play the effect for the treatment of both principal and secondary aspect of disease.And do not contain industry byproduct in raw material, can not introduce toxic metals element pollution soil, the 30d left and right can be increased to the pH of topsoil soils the scope (6.0-6.5) of suitable plant growth from utmost point acid condition (4.0).
Embodiment
Embodiment 1:
A kind of method of acid soil improvement, the steps include:
A, calcium carbonate and slaked lime are ground respectively, fineness requirement 80% or 85% or 90% or 95% or 100% is by 20 or 25 or 30 or 35 or 40 mesh sieves, obtains respectively a kind of calcium carbonate and slaked lime powder after levigate;
B, according to actual total consumption of using the acid modifying agent of area definition, the calcium carbonate that weighing is levigate and slaked lime powder fully mix according to weight ratio 3:0.8-1.2, make acid soil improving agent.
Before C, whole ground, the acid soil improving agent uniform surface is imposed on to upper soll layer, then carries out turning over of soil, by acid soil improving agent sneak into plow layer (1 or 59 or 13 17 or 20cm) in soil, and guarantee that acid soil improving agent mixes with soil.
D, acid soil improving agent Optimum are per hectare 3500 or 3650 or 3750 or 3800 or 4000kg.
The upper employing of soil (pH=4.0) the present invention in severe acidification is tested, and 10 square metres of community areas, repeat for three times.Calcium carbonate and slaked lime are ground respectively, and fineness requirement 80%-100% is by 20-40 mesh sieves, obtains respectively a kind of calcium carbonate and slaked lime after levigate.Levigate calcium carbonate and slaked lime are fully mixed according to weight ratio 3:0.8-1.2, make acid soil improving agent.Before whole ground, the acid soil improving agent uniform surface is imposed on to upper soll layer, then turn over and sneak in topsoil (0-20cm) soil, and guarantee evenly.The acid soil improving agent Optimum is per hectare 3500-4000kg.Detected the pH value of soil after using every 5d days.
Result of the test shows, the pH of topsoil soils can be increased to the scope (6.0-6.5) of suitable plant growth from utmost point acid condition (4.0) after using the acid modifying agent 30d of the present invention.
