Abstract

The present invention discloses a method for treating desertified soil into fertile soil. In the method, firstly, catalysts are combined with accumulated and weathered sand, stone and dust in the desertified soil; then plants are planted on the soil; finally, nutrient liquid is sprayed on the plants. By using the method, the desertified soil is thoroughly modified, and industrial crops can be planted on the soil. The method has the advantages of easy raw material acquisition and low cost.

Description

A kind ofly administer the method that the desertification soil is a fertile soil

Technical field

The present invention relates to a kind of method that the desertification soil is a fertile soil of administering.

Background technology

At present, the crisis of desertification of land is extremely urgent.Because closing on of desertification, the livelihood of the whole world 1,000,000,000 above populations faces threat, the grain that the people more than 800,000,000 does not earn a bare living at least, and 1.35 hundred million people leave the native place.Estimate that according to United Nations Environment Programme (UNEP) desertification makes the whole world suffer 42,000,000,000 dollars loss every year, has the nonirrigated farmland of 110 countries to face potential danger.Desertification is acknowledged as " cancer of the earth ", and its swift and violent expansion has threatened all ecospheres on the earth, that is human basic living environment.

China just expands with 2460 square kilometres speed in annual desertification soil dissolvingly.Desert, the desertification land total area in the whole nation are 2,620,000 square kilometres, have surpassed the summation of national cultivated area.If the situation in 7,000,000 mu of arable lands of annual since the establishment of the nation decreased average can not get changing, the per capita cultivated land of China is with 0.7 mu of less than after 50 years.After 200 years, then do not have one-inch to plough, do not plough and do not plant, do not do any farm work, both do not had recuperation, more do not have and live.

In the face of the desertification in soil, a large amount of scholars study, and have proposed numerous solutions.But still there is not complete and effective solution at present." the grid grass planting method " of China's research, on the desert, breaking into grid with straw, corn stalk and other paddy grass on the desert, fixed the sand very big effect, but its cost height, waste many human and material resources, also to do year after year, only play sand fixation, all can not fundamentally change desert soil and soil property.

Summary of the invention

The purpose of this invention is to provide a kind of method that the desertification soil is a fertile soil of administering.

For achieving the above object, the present invention takes following scheme: after the sand in use activator and the desertification soil, stone and dust accumulation weathering combine earlier, become cultivable soil through chemical action, plant plant thereon, and spray nutritive medium in plant.Described activator makes after 1000～1200 ℃ of high-temperature roastings after being ground by sheet mica, domestic animals bone meal and shell class; The weight ratio of sheet mica, domestic animals bone meal and shell class is 5～10: 2～3: 1; Nutritive medium through cleaning and dewatering, adds that the well-done back of purple perilla high temperature is vexed to be steamed by the shell class of chopping and seaweed plant; The weight ratio of shell class, seaweed plant and purple perilla is 1: 1: 1; Vexed steaming temperature is 90～100 ℃, and the vexed steaming time is 1～3 hour.Plant can be the plant of drought resisting classes such as husky rice, sand sagebrush (Artemisia filifolia), locust tree, cypress, grass.

Described shell class is a kind of of shell, shrimp and crab shells, cuttlefish cartilage or their mixture, bone meal that described domestic animals bone meal is ox, sheep, pig, horse or their mixture.Also the bone meal of fish be can use separately, or the bone meal of fish and the mixture of domestic animals bone meal used.

Sheet mica is from MICA, going into kiln after grinding smoulders, temperature rises to 1000-1200 ℃ of mica flake when spending and is subjected to high temperature to stimulate self expansion 8-12 doubly to be beautiful shape, husky and soil are played the mediation effect, fictitious time day slightly, sandy slowly the mixing with mica causes quality change to help plant to move to grow and the replacement fertilizer.The physics of the comprehensive bone meal of domestic animal contains phosphorus, potassium, nitrogen, magnesium, iodine, iron, zinc, copper and multiple dilute metal can make the mutual concussion of poor soil sand facies become new soil.

Because husky itself have very strong water-permeable and ventilation property, preserve moisture and fertility is poor, plant any crop on the desert, must at first change husky a series of shortcomings.After activator and loose sand, organism and dust accumulation weathering combined,, make the grains of sand that the variation of matter take place gradually, become the soil that Gong to cultivate through chemical action.After treating that crop emerges, spray nutritive medium, can further improve the soil and effectively sterilization around plant root, assist plant absorbing and keep nutrient, safeguard the growing environment of plant.

After plant goes out seedling,, can assemble fertilizer and nutrition, comprise the fixed action that nitrogen is fixing and microorganism absorbs at plant root through its sprinkling.

Nutritive medium also has following effect:

1. be used as recovery to soil fertility.

2. improve breeding to actinomyces in the soil.

3. promote that plant root phosphoric acid absorbs, activate plant by producing acetylene.

4. quite excellent moisture retention is arranged.

The definition in desertification soil: sand, desert, plateau loessland, bottom land, deserted mountain, desert, dust, waste valley, Hai Pu are neonatally, zone, spacious wilderness such as cement earth, ruins do not develop, and can't plant the barren soil of farm crop.

The effect such as the following table of all kinds of soil after use activator and the nutritive medium:

Soil	Before the use	After the use
Soil	Before the use	After the use	Sandy soil	Water-retentivity, nutrient preserving capability are poor, meta-acid, partially alkali Ph value greatly, should not plant plant.	We are at the situation of sandy potential of hydrogen, degree of crystallization and even freeness, place under the table soil (sand) with 1: 15,1: 20,1: 30 filler respectively, its cation exchange capacity is adjusted voluntarily, adaptive faculty finally produces the effect of preserve moisture and fertility.
Clay Hai Pu neonatally	Viscosity and alkalescence are strange big; soil property is sticking and poor; Chang Jishui (seashore); the low-lying seawater that throughout the year is subjected to is baptized; the drainage performance extreme difference; root solidifies; can not inhale fertilizer; mashed root, crop is withered on the ground.	The Ph value of general clay is all between 8.5-14.0, mostly impacted the Plain by river or ocean current, the method for improvement should be isolated 4-5cm with the clay soil property earlier.Use SULPHUR POWDER to make its drying loose, dispense activator covering table soil more then, its fertility can be combined with the crop of plantation, produce regulating effect, during this time every 45-60 chi periphery soil, to dig out a waterways between crop and the crop in case of necessity, the fertility that then can stablize crop root is easy to performance.	Sandy soil
Clay Hai Pu neonatally			Laterite loess	Meta-acid, viscosity are big, clay has the ponding ability, owing to being located in the plateau or being no ponding chance, nutrition is poor.	Because of the reddish yellow soil series ancient riverbed of the Yellow River, the sedimental grains of sand in tributary, Haihe River and massif wind sand blast erosion is piled up and is formed, we are after pushing table soil aside, should import immediately and put into activator after the special filler 2cm of activator adds a cover thin list soil again, make barren reddish yellow soil absorb nutrient and then storage nutrient gradually, reach the needs of plant-growth.
Barren deserted mountain	The Ph value is too high or too low, water-retentivity is very good or too poor, unsuitable crop existence does not meet cost of labor.	Stone matter hill slope, chaotic state is impacted the Plain, Gobi desert, sandy beach in front of the mountains, the sand grains deflation is piled up, on be the massif that flows, it is down hard poor soil, difficulty of governance is very high, though the timed interval for a long time, but we still can push table ore deposit and table soil open, in regular turn special activator is put into the dark soil of 2cm and added a cover thin soil again, spread down activator then.Though can only plant drought-resistant quite high plants such as husky rice, sand sagebrush (Artemisia filifolia), locust tree, cypress in 1 year, cultivate the absorption and the storage of the sharp fertility in water source earlier, but can consider to plant experimentally cash crop in 1 year, what wherein pay special attention to is that the water source provides situation.	Laterite loess

Advantage of the present invention is:

The desertification soil is improved up hill and dale, becomes fertile soil, and can plant economic crops thereon.

Preparation activator and the employed material of nutritive medium, it all is the waste of scorning to take even a glance in the human daily life, as first skin of crab class, shrimp shell, insect or the cartilage of cuttlefish, butterfly, mushroom class class, germ class cell walls or the like, tellurian storage can reach 1,000 hundred million tons according to estimates, be only second to the rich in natural resources of cellulosic, they will play immeasurable effect to crop growth.And improved soil function, reduced the improvement cost.

Embodiment

1. the preparation of activator

Get sheet mica 10kg, Os Sus domestica powder 5kg and shell 1kg and grind in the input high-temperature reactor of back, after 1100 ℃ of high-temperature roastings, make activator 4.80kg.

2. the preparation of nutritive medium

Each 5kg of shell, marine alga and purple perilla is dropped in the closed reactor, and discharging after 100 ℃ vexed steaming naturally cooled to room temperature after 2 hours down can get nutritive medium 10kg.

3. to the processing in desertification soil

After sand in use activator and the desertification soil, stone and dust accumulation weathering combine earlier, plant cypress thereon, then plant is sprayed nutritive medium.
