Description
Technical field
The present invention relates to a kind of lawn in saline-alkali soil breeding method, and in particular to a kind of sloping field type heavy saline-alkali area at seashore lawn training
Educate method.
Background technology
It is well known that the greening to salt-soda soil, the soil removal and replacement greening method generally used at present, it is to existing arable land and ecology
Environment does a lot of damage.
Using it is with low cost and meet " original soil greening " technology of sustainable gardening and afforestation development principle gradually by
People are paid attention to.If carrying out original soil greening, there is very big benifit to the sustainable development of ecological environment, but salt-soda soil original soil is afforested
Difficulty it is high.
Lawn is as a kind of indispensable vegetation pattern of Green-land Ecosystem, not only with greening, beautification soil environment
Function, also certain soil improvement action.It can effectively cover exposed earth's surface within a short period of time, reduce the surface water
Divide evaporation.
For sloping field type beach saline land, if cultivating lawn success, its soil environment will be substantially improved, to greening
Beach saline land is significant.But due to level of ground water, the high degree of mineralization of ground water and it is high steam drop than the problem of, moreover, planting
It is even more rareness, ecology fragility, severe water and soil erosion；Lawn is cultivated in sloping field type beach saline land, survival rate is low, into level ground ability
Difference.
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 sloping field type heavy saline-alkali area at seashore lawn cultivation side
Method, improves lawn survival rate, improves turf speed.
To solve existing technical problem, the technical solution adopted by the present invention is：A kind of sloping field type heavy saline-alkali area at seashore grass
Level ground breeding method, comprises the following steps：
Step 1 salt-soda soil is selected
2013~2016 years, this Research Team optional test status was located in in the northern heavy saline-alkali area at seashore in Weifang City of Shandong Province
Sloping field type location, the gradient is 28~31 °, and upper soll layer is silty sand silt clay, and pH is 8.5~8.7, and saliferous is higher than 4.0%；
60cm is divided into master with sodium chloride salt, can ploughed the following is the fine and smooth cement particle of the mud formed based on marine sediments, soil
Make the average thickness of layer for 30~35cm.
Step 2 desalting system is laid
Moved towards along the height in hillside fields, taken advantage of a situation from hillside fields top to hillside fields base portion excavation salt discharge ditch, salt discharge 1~1.2m of ditch depth, ditch
Interior laying salt discharge hidden pipe, is laid according to the pipe of a ditch one, and salt discharge ditch spacing is 5~5.5m, the elongation at break of the hidden pipe
For 200~250%, longitudinal welds（110℃）For 1.8~2.1%；The thick original soils of 50cm are embedded to after laying, are poured water 1 time along ditch,
Soil is slightly sunk in fact, then original soil is filled out into back ditch middle berth flat raft salt ditch.
Step 3 irrigation system is laid
Using corrosion resistant plastic water pipe, 75~80cm depths below earth's surface is laid side by side, water pipe laying spacing is 5 meters；Water
Irrigation water is introduced at Guan Kecong water sources；A sparge pipe is set up on water pipe every 5 meters to may extend to more than earth's surface at 15~20cm,
The sparge pipe mouth of pipe be provided with can 360 ° water spray shower nozzle；Make water spray can be with the soil of all green belt of bedding.
Step 4 original soil is arranged
By green belt earth's surface to deep Soil tillages of 30~40cm one time, it is careful not to destroy irrigation system, during turning over, applies
Enter base manure, base manure is 2.5~4t of the farm manure/mu become thoroughly decomposed；Topsoil rake is carefully raked；
It is horizontally-parallel to be divided into 3 lawns region by sloping field type salt-soda soil according to physical features height；To hillside fields base portion at the top of from hillside fields
The first lawn region, the second lawn region and the 3rd lawn region, the geopotentia that each lawn region is crossed over are labeled as successively
It is basically identical.
Step 5 kind plants Festuca Arundinacea
Festuca Arundinacea is planted into the first lawn region, specific method is as follows：
July, sowing is soaked seed 20~30min before sowing with 2.3% limewash, then dressed seed with seed dressing and under the sun solarization it is 1 small
When after can sow；The seed dressing is：50% carbendazol wettable powder：Margosine is according to 5:1 mass ratio is mixed.
Using drilling, mu 2.3~2.4kg of application rate, seedling stage timely Nitrogen Top Dressing in 2-3 piece leaves, mu applies 15~17kg
Urea；After planting, sprinkling irrigation in every 10 days once, during sprinkling irrigation uses sulfur acid ferrous iron 1.8~2.2%, lanthanum nitrate 0.05~0.1%, Asia
The water of potassium selenate 1.2~1.8%, above-mentioned percentage is mass percent.
Step 6 kind plants Manila grass
Manila grass is planted into the second lawn region, specific method is as follows：
July is sowed, and is soaked seed 40~50min with 2.2% sulfuric acid before sowing, using broadcasting sowing, mu application rate is 3.2~3.5kg；
After planting, every spray irrigation in 10 days is once；It is relatively low to fertilizer nutrient, animated period is grown, every 20 days Fertigations are once
Can, dose is 10kg/ mus；The material that applies fertilizer is 15~17 parts of fulvic acid, 1~2 part of calcium nitrate, 3~4 parts of ammonium sulfate, zinc sulfate
1.5~2 parts, 0.5~0.8 part of potassium selenite mix, above-mentioned number is parts by weight.
Step 7 kind plants English ryegrass
English ryegrass is planted into the 3rd lawn region, specific method is as follows：
Implantation time is May, is sowed during 16~18 DEG C of temperature of selection, sows presoaking and germinating in first 3 days, seed is soaked in into Yin
Indolylbutyric acid and margosine are with mass ratio 3：1 is configured to soak 40 minutes in the mg/L of concentration 500 solution；
15~20 kgs/acre of nitrogen-phosphorus-potassium compound fertilizer, the composite fertilizer nitrogenous 10%, phosphorus 5%, potassium are spread fertilizer over the fields into growing area before sowing
10%；
Then turn over plow harrow carefully smooth, fertilizer and soil are well mixed；Ploughed the first furrow as a guideline by 1 meter of bracing wire of breadth；After moisture in the soil face is smooth, with line-spacing
13~15cm, 6~7cm of sown scope, every mu of 0.8~1 kilogram of seed sowing.Rear 1.9~2.2cm of earthing is broadcast, is so conducive to seed
Germination and enhancing drought-resistant ability.
Sowing is irrigated after terminating, and water spray leaching moisture in the soil, notes that moisture in the soil can not be overflow, gone out to prevent seed by water during irrigation.
Step 8 kind is managed after planting
At after planting 56~60 days for the first time cut the grass on a lawn, the lawn in whole green belt be intended to trimming, the height for the stubble left be 5~
6cm；Later a lawn was trimmed every 40~45 days；
Annual 5~July with 75% Bravo and 20% powder pound would rather WP respectively to water dilute 1000 times of liquid, rotation spray
Apply, interval is sprayed once for 20 days.
By adopting the above-described technical solution, the present invention reach have the technical effect that：
1st, sloping field type salt-soda soil of the present invention original soil cultivates lawn effect substantially, and lawn cultivating survival rate is high, and Festuca Arundinacea survival rate is high
Up to 91.2~99.5%, Manila grass survival rate is up to 95.7~98.8%, and English ryegrass survival rate is up to 90.9~
96.2%。
2nd, sloping field type salt-soda soil of the present invention original soil cultivates lawn turf speed soon, 2~3 months after plantation can Cheng Ping.
3rd, sloping field type salt-soda soil of the present invention original soil cultivates lawn, and strong stress resistance is difficult to degenerate, the 3rd year after plantation, overall grass
Level ground storage rate still can reach 90.2~95.5%.
