Description
Technical field
The present invention relates to a kind of saline land greening method, and in particular to a kind of heavy saline-alkali area at seashore original soil greening method.
Background technology
Heavy saline-alkali area at seashore exist phreatic high, the high degree of mineralization of ground water and it is high steam drop than the problem of, vegetation is rare,
Ecology fragility, constrains salt-soda soil afforestation.
At present, domestic many related city such as ground such as Binhai New Area in Tianjin, Delta Region of The Yellow River, Hangzhou Wan new district is green
Change the engineerings for using " separation layer+soil moved in improve the original " more and keep away salt measure, carry out lowering of watertable, reduce soil salt content, contain soil
After the control of salt amount is below 0.4%, then carry out Garden Greenland construction.Although above-mentioned measure obtains some effects, but there is also
Serious problems.One is that not only cost is high, standing charges are big, is that the maintenance management in later stage has buried a variety of hidden danger, and due to
Soil moved in improve the original is planted, and substantial amounts of good farmland will be destroyed every year（1 square metre is often afforested generally on salt marsh, it is necessary to from existing arable land
On take 1 cubic metre of excellent planting soil as soil moved in improve the original）.Because land resource is non-renewable, the soil removal and replacement greening generally used at present
Method does a lot of damage to existing arable land and ecological environment；Two be plantation some traditional its salt resistance abilities of salt tolerant seeds compared with
It is low, landscape effect be also difficult to persistently, occur " 1 year it is green, 2 years it is yellow, enter the chamber of a kitchen range within 3 years ", even occur that " spring greening, summer are yellow
The phenomenon of change, autumn albefaction ".Using with low cost and meet " original soil greening " skill of sustainable gardening and afforestation development principle
Art is gradually valued by the people.
Autumn spends Luan Shu deep-rootedness, grows middling speed, relatively delays when young, later gradually fast.To wind, dust pollution, sulfur dioxide, ozone
There is stronger resistance；It is good green plants, but original soil is cultivated in the heavy saline-alkali area at seashore of northern China, for garden
Woods is afforested, and autumn flower Luan Shu young growth storage rates are relatively low, or even introduce a fine variety unsuccessfully, mortality.
The content of the invention
In view of the shortcomings of the prior art, it is an object of the invention to provide a kind of heavy saline-alkali area at seashore original soil greening method, carry
Young growth storage rates of the high autumn flower Luan Shu in the greening of northern heavy saline-alkali area at seashore original soil.
To solve existing technical problem, the technical solution adopted by the present invention is：A kind of heavy saline-alkali area at seashore original soil greening
Method, comprises the following steps：
Step 1 salt-soda soil is selected
Experimental field it is located in the northern heavy saline-alkali area at seashore in Weifang City of Shandong Province, surface soil layer pH is 8.4, total salt content is after measured
0.48%, growth has that alkali is fluffy, Salt And Alkali Tolerance weeds, no shrub or arbor vegetation growth.
Step 2 original soil is arranged
The weeds in green belt salt-soda soil are removed, using mechanical soil deeptillage, base manure is used sufficient during ploughing deeply；Base manure is the agriculture become thoroughly decomposed
Fertile 3-4t/the mu of family；Meanwhile, soil is carried out disinfection using 50% carbendazol wettable powder, the amount of spreading fertilizer over the fields is 30-50g/ ㎡.
In green belt ridging, ridge face width 0.5-0.6m forms width 0.4-0.6m, depth 0.3-0.5m ditch between ridge and ridge,
Salt discharge hidden pipe is embedded with ditch, the landfill depth of salt discharge hidden pipe is from surface soil 1.2-1.5m.
Step 3 selection autumn flower Luan Shu cuttings
August part, selection is healthy and strong, lateral bud is full, the no disease and pests harm autumn spends Luan Shu branches as cuttings, and cuttings stem is slightly 1.2-
1.5cm, is cut into 20-25cm segment, cuttings with 2-4 axillary bud；
By the oblique partial application in cuttings lower end, otch buries the cuttings put in order with wet sand apart from bottom lateral bud 10-11cm, wet
Husky water content makes cuttings be effectively maintained moisture between 56-63%.
Pre-processed before step 4 cuttage
September part, cuttings is taken out from wet sand, and lower end is immersed in 8 hours in 50% carbendazol wettable powder, 500 times of liquid and carried out
Sterilization；
After sterilization, cuttings is removed and placed in heteroauxin and margosine with mass ratio 3：1 is configured to concentration 400-500 mg/L
Solution in soak 20-40 minutes.
The step 5 cuttage autumn spends Luan Shu
Diameter 2cm cylindrical wooden bastinade nest is used on the face of ridge, nest depth is beaten for 10-20cm；Anti-corrosion once is dipped in into cuttings lower end
Take root paste, be gently put into nest, filled with matrix, the lateral bud of bottom is just basseted, be gently compacted；
The preparation method of the anti-saprophytic root paste is：By methyl α-naphthyl acetate, thiamine hydrochloride, carbendazim according to 1:2:7 mass ratio is mixed
Water spray is adjusted to water content 65% after conjunction, stirs into pastel.
The matrix used is filled by turfy soil, oyster shell powder, fertile soil, vermiculite, camellia pollen, jujube core powder according to 10:2:7:
1:3:5 mass ratio is mixed to prepare, and is squirted with fresh water, and it is 50% to make water content.
Arranged per ridge cuttage one, cuttage spacing in the rows is 50cm.
Step 6 kind plants mongolian bluebeard
Mongolian bluebeard is planted in the ditch for spending between goldenrain tree tree planting ridge in the autumn, a row mongolian bluebeard is planted per ditch, plant is away from for 40-
60cm。
Step 7 kind is managed after planting
A fresh water is irrigated immediately after plantation autumn flower Luan Shu and mongolian bluebeard；After irrigation, with original soil to cutting earthing once；
After, spring and autumn irrigates a fresh water for every 30 days, and every 20 days of summer irrigated a fresh water, and winter need not irrigate；
During the annual 4-8 months, monthly topdress once, dose is 50kg/ mus, including kg/ mus of composite fertilizer 20 and middle amount fertilizer
30 kg/ mus；Described composite fertilizer's N P and K mass content is 30%, 15%, 15%, and described middle amount fertilizer includes calcium nitrate 10%, sulphur
Sour ammonium 10%, EDTA-Fe 1%, jasmonic 3%, ferrous sulfate 10%, lanthanum nitrate 0.5%, potassium selenite 4%, citric acid 7%, biochemical Huang
Humic acid 54.5%, above-mentioned percentage is mass percent；
Annual spring sprays 70% thiophanate methyl wettable powder, 1000 times of liquid to green belt, and sprinkling in every 20 days is once；
Annual summer is diluted with water 1000 times of liquid respectively with 75% Bravo and 20% triadimefon wettable powder, and rotation is sprayed,
Every 1 week, spray 6-8 times altogether.
By adopting the above-described technical solution, the present invention reach have the technical effect that：
1st, substantially, advantitious plant survival rate is high for original soil afforestation effect of the present invention, and autumn flower Luan Shu cuttage survival rate is 99.5-99.7%,
The survival rate of mongolian bluebeard is 94.5-95.2%；
2nd, the present invention carries out original soil greening in heavy saline-alkali area at seashore, and autumn flower Luan Shu young growth storage rate is up to 98.6-98.9%；
3rd, the present invention carries out original soil greening in heavy saline-alkali area at seashore, and the storage rate that grows into forest for introducing a fine variety the 6th year autumn flower Luan Shu is still up to
96.5-96.8%。
