Description
Technical field
The present invention relates to a kind of preserving soil moisture method more particularly to a kind of ternary of Karst Rocky Desertification Region agroforest system soil
Earth method for preserving soil moisture belongs to field test detection technique field.
Background technique
Agroforest system also known as farm forestry, agroforestry, forestry management etc., concept saying is more, relatively generally acknowledges
One is " agroforest system is the general term for illustrating land use and method, on this soil, perennial woody plant
Object, as crops (or livestock), with different space arrangement and time series, in the culture of same soil, each section
Between have ecology and economic link ".
The Karst region rain hot same period, rainfall is abundant, and soluble fracture is distributed more widely, dissolves and invades for a long time through rainwater
Erosion, to form its unique " earth's surface-underground " dual structure, moisture leakage is serious, and utilization rate of fertilizer substantially reduces.In this way
Under environment, crops need water that can not ensure, especially spring drought season, rainfall is less, water shortage, and agricultural is impaired serious, harvest
Fall sharply, revenue decline, local economic development is slow, and people reclaim wasteland, and bring a series of environment to increase income
Problem then falls into the vicious circle of " more poor more cultivate, the more cultivate the more poor ".And when very heavy rains, shallow soil layer is washed away, and is made
At serious soil erosion, the exposed rate of rock rises, and ecological environment further deteriorates.A series of this problem seriously constrains
The scale enlargement of Karst Rocky Desertification Region farm forestry, efficiently plantation and popularization demonstration.At present to Karst Rocky Desertification Region
The preserving soil moisture technology and method of agroforest system have not been reported, while other plant and the method for preserving soil moisture in area are not suitable for karst
The plantation of regional agroforest system.Therefore research is suitable for the preserving soil moisture technology and method of Karst Rocky Desertification Region agroforest system, no
Problem of environmental pollution caused by laying plastic, crop straw burning or leaf etc. can only be reduced, meanwhile, reduce management cost, change give up into
It protects, it is economical and practical, for developing and promoting in area's large area, meanwhile, have great importance for the prevention and treatment of stony desertification.
Summary of the invention
The technical problem to be solved by the present invention is providing a kind of ternary preserving soil moisture of Karst Rocky Desertification Region agroforest system
Method can largely collect precipitation by cave hole+water-retaining agent+stalk/leaf/stone tertiary mode, store moisture, reduce and seep
Leakage increases utilization rate of fertilizer, reduces the soil moisture, evaporation is reduced, to have the function that retain and conserve soil moisture.And stalk etc. covers
Object can avoid raindrop and directly beat in upper soll layer, buffer raindrop kinetic energy, reduces to swash and splash, hinders water flow, reduce runoff, alleviate soil
Soil erosion harm.
The technical solution of the present invention is as follows: a kind of ternary preserving soil moisture method of Karst Rocky Desertification Region agroforest system, described
Method and step are as follows: one, size as needed digs cave hole, long-term cropping before the planting；Two, the 2- before rainy season set
3 days in every group of agroforest system using perennial crop as digging width 5-7cm, the circular groove of deep 10-15cm, by water-retaining agent at the radius 20cm of center
With soil by 1:1000(mass ratio) uniformly mix, every group with 30-40g water-retaining agent, then cover on it the thick soil of one layer of 5cm with
Water-retaining agent is avoided directly to contact with atmosphere；Three, one layer of stalk or leaf or stone are covered on upper soll layer；Four, when encounter connect
Continue arid weather should suitably water, until water-retaining agent be saturated with and until, provide water source for later period soil water supply.
In the step 1, the specification in cave hole is diameter 25-35cm, deep 20cm.
In the step 2, group is referred to centered on perennial crop, perennial crop surrounding plant 1 year or
Perennial plant, shape are that the circle of radius 1m or 1m multiply the rectangular of 1m.
In the step 3, the diameter of stone is 5-10cm, is paved with entire kind of plant hole, rock layer with a thickness of 5cm.
In the step 3, stalk, which is laid with, is cut into 50cm or so for corn stover or rice straw, is placed on kind of a plant hole, thick
Degree is 5cm.
In the step 3, fallen leaves are laid with and gather materials on the spot, and choose the fallen leaves of diameter 5-10cm, are paved with entire kind of plant hole, thick
Degree is 5cm.
The stalk and fallen leaves, which need to be sprayed with liquor potassic permanganate before laying, carries out sterilizing.
The beneficial effects of the present invention are:
One, the material that preserving soil moisture is utilized belongs to the local resource of one's native land possessed, and the utilization of stalk reduces due to burning
The atmosphere polluting problem of generation, leaf are easy to get, stone, especially the more place of rock exposure, can also largely be obtained, will
These material applications are economical and practical in agroforest system preserving soil moisture, work well, and can reduce because laying plastic is to soil ring
It is endangered caused by border and crops.
Two, stalk/leaf/stone that preserving soil moisture is utilized can effectively reduce the soil moisture, inhibit soil evaporativeness,
Improve the utilization efficiency of soil moisture, improve soil storage, thus plays drought resistance function.
Three, this preserving soil moisture mode makes the growing environment of plant be greatly improved, and fruit-setting rate significantly improves, under Cracking fruit
Drop is produced and is thrown than rising, income improves to increase the yield of per hectare area crop.
Four, Measures on Soil Moisture Conservation changes soil texture.Soil aggregate structure can be improved, stalk and leaf return agriculture after rotting
Field promotes the raising of soil organic matter content；Water-retaining agent water suction is expanded, and discharge water diminution, loosens soil layer, soil weight decline, hole
Gap space is reallocated, and rainfall infiltration and soil water storage ability are improved.
Five, water-retaining agent absorbable hundreds times bigger than own vol of water or even absorbable night dew, does not evaporate, not permeable
It absorbing water when leakage, rainy day or watering, when water shortage, discharges water, and 1-2 month can be delayed not have to watering, thus can reduce by 50% irrigation amount, saving
A large amount of water rate and the electricity charge, every group of agroforest system cost is at 1.2 yuan or so；Artificial 2-5 are saved, it is comprehensive per acre every year to save 200-
500 yuan；Survival rate of plant greatly improves, and reduces expense of filling the gaps with seedlings.
Six, fertilizer can be dissolved in the water and is being poured, fertilizer is stored in water-retaining agent, slow release, to avoid
The waste to fertilizer is leaked, effectively improves the utilization rate of fertilizer, and reduce the pollution to subterranean stream.
