Embodiment

Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing and preferred embodiment.As shown in the figure, a kind of barren soil plantation plant is spent the ecological moisturizing device that survives the key period, mainly be made of degraded vessel 1, degraded bag 2 and composite soil 3 and moisture film 4, described 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 described degraded bag.Described 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 plantation plant according to the apolegamy of routine ridging technology and spends the soil property that survives the key period according to floristics and local ecotope, and composite soil is full of moisture before plantation.

Degraded vessel and degraded bag shape can be made into circle, square bag shape.Specification is made 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 substantially.The degraded gradient that the degraded bag is selected according to plant characteristic after 30 days begins to break and degrades gradually, can provide the degraded bag interior moisture, nutrient solution and PH equilibrium liquid for plant 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 growth demand, 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, when spend survive the key period after, root system of plant then can utilize self characteristics, taking root rapidly penetrates the degraded vessel and finds water source under the 7 new environment of 6 times water-bearing layers of sand bed, and 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.By introduction and Experiment and investigation and analysis in recent years, we think in the process that desert highway biological protection system is built, and the selection of plant species is fixed the sand seeds so that yellow horn etc. is good.

2, structure and layout

Because the mechanical measures for sand prevention effective protecting time that is provided with during constructing highway is limited, bring into play its protection benefit in order to make the biological protection system substitute sand-protecting barrier as soon as possible, 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 the ecological moisturizing device that survives the key period and degrades gradually, can in a period of time, provide sufficient moisture and nutrient solution for nursery stock, make fix the sand sapling root growth rapidly and flourishing, to be that a dry sand layer is following be wet sand bed on the drift sand top 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, also will take different measures in the process of afforestation: 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.

Embodiment two

Plant on the ground at coastal saline-alkali soil, transplant 600 of Chinese scholar trees, diameter of a cross-section of a tree trunk 1.3 meters above the ground 10-15cm.

According to the size of transplanting nursery stock earthen platform, select different specifications, this transplants earthen platform diameter between 1m-1.5m, selects that diameter is 1.2, the degraded vessel of two kinds of specifications of 1.8m.

At first put into the degraded bag that several are equipped with water or pest repellant or biological fluids or nutrient solution or PH equilibrium liquid in the vessel in degraded, set up platform greatly after, carry out bagging, seal then.When planting, open and seal, pour water.Effect: plant percent 98%, transplanting seedling time shortened for 2 weeks, the nursery stock normal growth.

The above only is preferred embodiment of the present utility model, is not structure of the present utility model is done any pro forma restriction.Every foundation technical spirit of the present utility model all still belongs in the scope of the technical solution of the utility model any simple modification, equivalent variations and modification that above embodiment did.
