Description
Technical field
The present invention relates to soil-ripening technical field, and in particular to one kind lifting barren purple soil fertility of hills area sloping upland
Method and soil texture.
Background technology
Sichuan is mainly distributed on basin as the big province of grain-production, about 0.65 hundred million mu of its cultivated area, and mostly sloping upland
Hills area and basin week low mountain, have the characteristics that " steep, thin, thin, erosion, drought ".Restricted by topography and geomorphology, sloping upland about more than 80%
For " rain-fed agriculture ", tableland soil thickness is more slightly to ossify in below 60cm, structure, and organic matter lacks.But as aging adds
Fast and economic society development, more and more youth labours select immigrant laborers or are engaged in other industry, agricultural production
Required labour is deficient year by year, and the management mode of agricultural production also progressively develops from fine type to extensive style, causes soil texture
It is hardened, nutrient loss is serious, and soil is barrenr, all the more large chemical fertilizer amount of application the problems such as it is serious.Therefore, in view of problem above
Need to improve hills area sloping upland, quickly increase soil fertility, and promote hillside fields mechanized farming mode.
Sloping upland method of routinely improving the soil in hills area does not consider top of the slope slope foot soil layer difference at present, or soil amelioration depth is shallower, leads
Benefit of improving soil productivity timeliness is caused to there is very big problem.
The content of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide one kind to lift the barren purple soil of hills area sloping upland
The method and soil texture of fertility, improve soil texture, improve soil water-retaining, protect while realizing quick increase soil fertility
Fertilizer, drought-resistant ability, so that reach the target of increasing both production and income, and the good benefit that improved plot is maintained for a long time.
The purpose of the present invention is what is be achieved through the following technical solutions：
A kind of method for lifting the barren purple soil fertility of hills area sloping upland, comprises the following steps：
S1. sloping upland top layer mellow soil is peeled off, and retains the mellow soil being stripped；
S2. carry out that explosion is fetched earth or machinery fetches earth in the higher tableland of height above sea level, and explosion is fetched earth or machinery fetches earth to obtain
Rock debris and parent soil material moved to slope lower part tableland, form more than the substratum of 30cm thickness, make sloping upland formed the gradient
Single smooth plot less than 6 °；
S3. the stalk layer of 8~12cm thickness is covered on substratum；
S4. the mellow soil and muck of one layer of 24~26cm thickness, the mellow soil muck layer bag and then on stalk layer are uniformly backfilled
Mass ratio is included as 200:1 mellow soil and compost from earthworm；Then deep ploughing mixing is carried out using large-scale machinery of ploughing, by stalk and muck
It is sufficiently mixed in soil.
Further, the stalk is the stalk after crushing, and stalk length is 3~6cm.
Further, in the step S1, specific soil stripping method is：First by the ripe of 18~22cm of sloping upland top layer
Soil is peeled off, and retains mellow soil.
Further, in the step S2, specific implementation method is：Explosion is carried out in the higher tableland of height above sea level to fetch earth or machine
Tool fetches earth, and reduces height above sea level difference, and rock debris or parent soil material are carried to low level tableland, and it is single less than 6 ° to form the gradient
Plot.
Further, in the step S4, back fill course specific implementation method is：The top layer mellow soil that will be peeled off in step S1
Uniformly backfill with muck, then mixed stalk layer and mellow soil muck layer using deep ploughing machinery, and holding surface is smooth, and ensure
The whole block gradient is less than 6 °.
A kind of hills area sloping upland soil texture, hills area sloping upland soil texture is made by the above method.
The beneficial effects of the invention are as follows：1) compared with prior art, the present invention significantly reducing algebraic difference between adjacent gradients, it is convenient for machine
Tool metaplasia is produced；2) reach more than 60cm by improved soil thickness, show through the long-term location observation of our unit：60cm thickness
Soil layer drought-resistant can be up to 20d；3) substratum landfill crushing straw, increases straw utilization rate, with reference to deep ploughing technology and organic fertilizer
Mixed activation principle, increases soil organic matter content, is conducive to improve soil structure and soil fertility at the middle and upper levels, reduces the soil water
Divide evaporation and leaching；4) the improved plot fertility lifting speed of this method is fast, and this season can realize volume increase, and lasts are made
Grown with the time, the crop weight-reducing volume increase time is 5~8 years.
