Embodiment
Specify embodiment of the present invention below in conjunction with accompanying drawing and preferred embodiment.As shown in the figure; The ecological moisturizing device that a kind of barren soil plantation plant is spent into the key period alive; Mainly be made up of degraded vessel 1, degraded bag 2 and composite soil 3 and moisture film 4, said degraded vessel is built-in with several degraded bags, is filled with composite soil between the degraded bag.Be equipped with water 5 or pest repellant or biological fluids or nutrient solution or PH equilibrium liquid in the said degraded bag.Said degraded vessel, moisture film and degraded bag are provided with different degradation times, and degradation time is set as gradient degraded, the degradation time scope 1-24 month.
Degradable material can be selected the ripe biodegradation material of market supply.Its degradative phase is 1-24 month.Composite soil is beneficial to the soil property that the plantation plant is spent into the key period alive based on floristics and local ecological environment according to the apolegamy of routine ridging technology, and composite soil is full of moisture before plantation.
The degraded vessel can be made into circle, square bag shape with the degraded bag shape.Specification is processed plurality of specifications according to the root system of plant size.Part biological liquid in the degraded bag or nutrient solution can be according to plant variety by the different time sections configurations, and the time can extend to 24 months.
Principle: before plantation, be full of moisture in the composite soil of degraded in the vessel, (in the middle of the conditional region can also manual watering keep the skin wet), the moisture of composite soil can satisfy the nearly 30 days demand of plant basically.The degraded gradient that the degraded bag is selected according to plant characteristic after 30 days begins to break and degraded gradually, can for plant moisture, nutrient solution and PH equilibrium liquid in the degraded bag be provided gradually in 1-12 month.According to the plant growing rule, the one-tenth current of plant cultivating or transplanting is roughly in 1 year.After 1 year, the hydrotropism of the plant utilization root system of plant of plantation or transplanting, when the external moisture that provides can not satisfy its growing requirements, root system of plant then can initiatively be sought new water source.Adopt ecological moisturizing device then can help plant to adapt to new transplanting or plantation environment; Biological fluids or nutrient solution or PH equilibrium liquid and composite soil are grown in the use degraded bag; After spending into the key period alive; Root system of plant then can utilize self characteristics, take root rapidly penetrate the degraded vessel find the water source under the 7 new environment of 6 times water-bearing layers of sand bed, favourable its grows vigorously.
Embodiment one
1, plant species is selected
Takla Makan Desert innerland except that the photo-thermal aboundresources to the growth of plant favourable, therefore other all factors all are unfavorable for plant growing, when selecting plant species, pay special attention to the husky characteristic such as bury of the salt tolerant of plant, drought-enduring, high temperature resistant, weatherproof.Through introduction and Experiment and investigation and analysis in recent years, we think in the process that desert highway biological protection system is built, and good to fix the sand seeds be main with yellow horn etc. in the selection of plant species.
2, structure and layout
Because the mechanical measures for sand prevention effective protecting time that is provided with during constructing highway is limited, substitute its protection benefit of sand-protecting barrier performance as soon as possible in order to make the biological protection system, but when desert highway biological protection system is built rational close planted, the seeding row spacing of employing 1--4m.Tree arrangement can adopt duplicate rows or multirow to mix in the ranks and hand over.
Planting season is preferably selected the planting-season in early spring.
Concrete grammar: the bag of will degrading is opened, and inwardly is full of water or pest repellant or biological fluids or nutrient solution or PH equilibrium liquid respectively, and sack is sealed.Select the degraded bag of different degradation times to be put at interval in the degraded vessel, will fix the sand sapling to put into the degraded vessel, recharge composite soil compacting back and cover moisture film, divide evaporation to prevent water.As time passes, barren soil plantation plant is spent into the ecological moisturizing device of key period alive and degrades gradually, can in a period of time, for nursery stock sufficient moisture and nutrient solution be provided; Make and fix the sand the root growth of sapling rapidly and flourishing, the drift sand top layer is to be wet sand bed below the dry sand layer usually, behind the plant germination on the drift sand; The main root root system can penetrate the degraded vessel and initiatively seek new water source; Have rapid extension,, spend the growth key period smoothly to reach the ability of consistent wet sand bed as early as possible.
Simultaneously, in the process of afforestation, also will take different measures: 1) water retention capacity of aeolian sandy soil is poor, and the need water that the water-holding capacity in the soil can not satisfy seedling requires and influences seedling development.Therefore, upload when planting, should in the hole that plants trees, be affixed by some clays or water-loss reducer, promote growing of nursery stock with the retention ability that increases sandy soil at mild mobile sand.2) to strengthen tending management behind the seedling planting, particularly the seedling phase except normal fertilising with prevent the damage by disease and insect, strong wind also will in time observe the wind erosion sand of nursery stock bury situation later, so that take corresponding emergency measures, promotes growing of forest.
