Described orange peel is that fresh orange peel is soaked in water and fully becomes thoroughly decomposed.
Further, during described lifting, soil gauge ball lattice are 5~9 times of the Quercus mongolica diameter of a cross-section of a tree trunk 1.3 meters above the ground, and use straw rope Mi Bao. Ensure that otch of being completely cured to smooth, occur without splitting phenomena.
Further, described step 4) for planting time, cut off soil straw rope packaging ball outside, when cultivating soil often backfills 15~30cm thickness, compacting once, final ensures that native ball clay face is above the ground level 10~20cm. If A-frame fixes (Anti-blow-open rocks, it is ensured that root system is stable);
Further, described pruning suitably to be pruned, and cuts off at female long 1/2 place's cutting back of branch, leaves middle long female branch, reduces Quercus mongolica transpiration, it is ensured that tree-shaped is attractive in appearance.
Further, described fertilizer adopts potassium sulfate, carbamide, calcium superphosphate, farm manure to be uniformly mixed for 2:3:1:3 in mass ratio, and described every Quercus mongolica dose is 500~1000g. Preferably, described farm manure is fermentation temperature is the Chicken dung of more than 70 DEG C. Described fertilizing method is with trunk center for the center of circle, excavates the annular groove of deep 20~25cm, wide 15~25cm along tree crown outward flange, and ensures that annular groove internal diameter is consistent with tree crown radius, applies earthing after fertilizer, waters permeable.
The present invention is had the advantages that
Compared with existing tradition method for planting, the method is that Quercus mongolica has started technical example in the application of planting of beach saline land, improves landscape engineering project of parks and gardens' afforesting effect.
Cultural method provided by the invention is planted for beach saline land Quercus mongolica, overcome the physiological defect that Quercus mongolica grows when beach saline land, effectively improve the Soil structure in salt-soda soil, reduce soil pH value, improve survival rate and the ornamental value of Quercus mongolica.
Detailed description of the invention
For setting forth thought and the purpose of the present invention, below in conjunction with specific embodiment, the present invention is described further.
Embodiment 1
Applying the inventive method to Tianjin seismic network real estate view Improving Project, this project construction time is April 2, and the Project Areas salinization of soil is serious, and groundwater level is high, and the content of organic matter is low, and Quercus mongolica growth is very unfavorable. The Quercus mongolica of plantation is only dry Quercus mongolica.
The method for planting of a kind of beach saline land Quercus mongolica, comprises the steps:
Step one, to cultivation bed process: to cultivate ground, bed place for benchmark, dig 80cm vertically downward, lay in area of knockout 20cm thick every drenching layer, described is that rubble, coarse sand are laid with mass ratio 3:1 Homogeneous phase mixing and formed every drenching layer, and upper surface lays geotextiles. Then building pool wall by laying bricks or stones, it is high to distance ground 30cm that pool wall adopts brick to build. (raise plant plantation elevation, lay after drenching layer, by increasing capacitance it is possible to increase cultivating soil breathability, can effectively control Underground Salt aqueous alkali and upwards migrate)
Step 2, preparation good permeability slant acidity cultivating soil.Described cultivating soil, adopting mass ratio is that 40% garden mould, 30% turfy soil, 10% pond sludge, 10% cinder, 10% orange peel are uniformly mixed, and described orange peel is that fresh orange peel is soaked in water and fully becomes thoroughly decomposed.
Step 3, the lifting time for plant morning 5 on the same day time, the fastest lifting time and seedling transportation time cumulation are 4 hours, transplant during the morning 9. Choosing the nursery stock that diameter of a cross-section of a tree trunk 1.3 meters above the ground specification is 10cm, soil bulb diameter is sized to 90cm, and lifting otch of being completely cured ensures smooth, occurs without splitting phenomena, and uses straw rope Mi Bao, it is ensured that integrity.
Step 4, when planting, cutting off soil straw rope packaging ball outside, cultivating soil often backfills 20cm, and compacting once, makes soil ball contact with soil closely, and finally native ball clay face is above the ground level 15cm. If A-frame is fixed, Anti-blow-open rocks, it is ensured that root system is stable.
Step 5, pruning. Described pruning suitably to be pruned, and cuts off at female long 1/2 place's cutting back of branch, leaves middle long female branch, reduces Quercus mongolica transpiration, it is ensured that tree-shaped is attractive in appearance.
Step 6, sprinkling plant transpiration resistant agent, root-growing agent, agricultural chemical Genfukang. Described plant transpiration resistant agent is watered 100 times of dilutions, and the same day after field planting is overall sprinkling (including trunk) rapidly, within every 4 days afterwards, sprays once, sprays 3 times continuously; Described root-growing agent, after field planting first time waters, is watered 500 times of direct pouring plant pits of dilution, and pouring once, to promote root system wound healing, quickly bears new root; Described agricultural chemical Genfukang is watered dilution 600 times, sprayed once every 8 days, continuous administration 3 times, to prevent butt rot, promotes to survive.
Step 7, rich water quality management. Transplanting watered the same day irrigates, and waters 5 times, watered once every 20 days afterwards within the last fortnight; Every 20 days, Quercus mongolica is topdressed once. Fertilizer adopts potassium sulfate, carbamide, calcium superphosphate, farm manure to be uniformly mixed for 2:3:1:3 in mass ratio, and described every Quercus mongolica dose is 600g. Farm manure is fermentation temperature is the Chicken dung of 70 DEG C. Described fertilizing method is with trunk center for the center of circle, excavates the annular groove of deep 20cm, wide 20cm along tree crown outward flange, and ensures that annular groove internal diameter is consistent with tree crown radius, applies earthing after fertilizer, waters permeable.
