Technical field
The invention belongs to method of tackling desert field more particularly to a kind of desertification soil remediation methods.
Background technique
Desert is primarily referred to as ground completely by sand covers, plant is very rare, rainwater is rare, air dried uncultivated
Area.Desert Producing reason mainly include overgraze, it is unreasonable fall trees, now the whole world desertification phenomenon
Seriously, desert area increases year by year.Desert area excessively can have very big influence to agricultural, animal husbandry, river and infrastructure.
Such as: increasing year by year for desert area can be such that the acreage under cultivation of agricultural reduces, and reduce national food annual output;Desert will lead to grass
Field is degenerated, and gradually decreases the advantage grass seeds suitable for livestock edible, or even completely lose, herbage becomes short, sparse, and yield is bright
Aobvious to reduce, grassland capacity for raising livestock on the grasslands greatly declines;Desert will cause river, reservoir, water channel and block, 1,600,000,000 tons of the average annual sediment transport in the Yellow River,
Wherein just there are 1,200,000,000 tons from Desertification, annual about more than 50,000 kilometers of the feed ditch in the whole nation is throughout the year by hazards of sand storms;Desert
Change and cause railway bed, bridge, culvert damage in some areas, makes highway subgrade, road surface sand, highway communication is forced to be interrupted,
Even make highway discarded;Dust and sand weather caused by desertification influences the normal takeoff and landing of aircraft;Wind-sand activity destruction communication,
Transmission line of electricity and facility, resulting disaster threat resident safety.The increase of desert area can aggravate regional poverty degree and add
Play, development gap expand, and according to investigations, Desertification is lived in the 1/4 of national people in the countryside, and agriculture value is only complete per capita
The 34.2% of state's average level is the 1/5 of eastern region.
The difficulty of control of desert has a two o'clock: 1, poor water retention property, and surface layer of desert has a deep fine sand layer, between fine sand between
Gap is larger and fine sand between universal combination constraint it is substantially zeroed.So the rainwater of the overwhelming majority can be straight from the gap between fine sand
Connect the desert depths that is lost and can not reach to root system of plant.Meanwhile desert day temperature is high, vegetation is not blocked, and leads to water
Point evaporation is fast, though after raining, rainwater also can rapid evaporation fall.2, nutrient preserving capability is poor, and the structure of desert soil is destroyed, soil nutrient
It has been be lost that, while the viscosity between fine sand is insufficient, causes nutrient that can not be attached to fine sand surface, can not supply naturally to plant
Nutrition.Due to the particularity of above-mentioned two o'clock, desert transformation needs to change the planting environment of desert soil, the manpower that needs to spend,
Financial resources are huge.Or even when the fertilizer synergist used in governance process and water-retaining agent or even inappropriate implantation methods, lead to sand
The water-retaining property and nutrient preserving capability on unconcerned surface layer cannot reach the requirement of plant long term growth, lead to plant mortality, to cause sand
Unconcerned regulation effect is little, wastes a large amount of financial resources, human input.
China belongs to the biggish country of desert area owning amount, about 700,000 sq-km of the desert gross area, if together with 50
The gobi of more ten thousand sq-kms the interior gross area be 1,280,000 sq-kms, the 13% of the land the Zhan Quanguo gross area.So China is right
Control of desert is just constantly made efforts and is improved since the establishment of the nation certainly, but regulation effect is little, also waste vast resources.At present
Desert control method mostly use artificial watering greatly, after watering using rotary cultivator carry out it is longitudinal dig pit, then by water-retaining agent and increasing
Fertile agent and fine sand mixing, finally carry out seedling cultivation.This effect can only allow the surface layer of desert of short duration time interior with plant growth
Condition be just no longer appropriate for plant growth after Sandy Soil is dry, plant can not be absorbed into more moisture and nutrient, from
It is so just withered to die, can not long-term continued propagation, circulation is previous, control of desert failure.
