Abstract
The invention relates to the technical field of tall fescue grass cultivation, in particular to a technology for cultivating and greening tall fescue grass on inshore mud flat saline-alkali soil. The technology includes the following steps of firstly, leveling a land; secondly, laying a mesh-shaped water irrigation and drainage pipeline net; thirdly, laying a sand layer; fourthly, laying an organic fertilizer layer; fifthly, sowing seeds; sixthly, strengthening seedlings; seventhly, shearing tall fescue grass and applying fertilizer; eighthly, conducting maintenance. The technology has the advantages that by lowering the underground water level of the inshore mud flat saline-alkali soil through irrigation and drainage measures, dehydration and dealkalization are rapidly achieved for the soil, and an environment suitable for growth of tall fescue grass is obtained. The technology can be applied to field greening construction of golf ranges, golf courses, football fields and the like in high-concentration salt and alkali regions, and can be applied to lawn greening, beautifying and damp preventing embankments and reservoir grassed slopes in coastal cities in high-concentration salt and alkaline lands; meanwhile, the technology plays extremely important roles in improving the ecological environment, improving the salt and alkali soil on a large scale, enlarging grain field areas, and relieving land arguing contradictories between urban lands and basic farmlands.
Description
Technical field
The present invention relates to tall grass culture technique field, particularly the cultivating green technology of beach saline land, a kind of coastal waters tall grass.
background technology
Part coastal waters beach is because subterranean water level is high, evaporation discharge large, soil is rich in salinity, tide is attacked often, major part is beach heavy saline, earth's surface and soil salt content are at 0.3-1.9%, pH value is between 8.0-8.9, and ecological afforestation condition inadequate natural endowment, only has fluffy, the red alkali of a small amount of alkali fragmentary distribution the such as fluffy, most of exposed alkali field, not even a blade of grass grows.If do not taked the technical measures such as engineering, all plants are all difficult to growth, because soil saliferous alkali number is high, greening land occupation condition extreme difference; cause that survival rate is low, storage rate is low, lack vegetation protection, ecological degeneration; severe water and soil erosion, moistureproof embankment is washed away by tide, and dyke forms safely hidden danger.
Tall grass is conventional afforestation vegetation, its property happiness cold wet, warm weather, optimum pH value is 5.5-7.5, Salt And Alkali Tolerance degree is generally below 0.2%, therefore under field conditions (factors), tall grass cannot be planted on beach saline land, coastal waters, and it faces many technical problems, therefore how waking the beach saline-alkali ground resource of being sunk into sleep for many years up, is the emphasis that countless experts study for a long period of time.
Summary of the invention
The present invention, in order to make up the defect of prior art, provides the cultivating green technology that a kind of efficiency of construction is high, manage beach saline land, the coastal waters tall grass of easy to use and suitable tall grass plantation.
The present invention is achieved through the following technical solutions:
A cultivating green technology for beach saline land, coastal waters tall grass, is characterized in that: comprise the steps:
(1) leveling soil: remove the object that upper soll layer hinders mechanical work, affects grass growth, the cleaning degree of depth is 30-40 centimetre, is then less than 1/500 according to the direction gradient of longitudinally pouring water, laterally fall with the ratio of level, cut height and fill out low-lying area, flattened, ensure that later stage irrigation and drainage are unimpeded; Leveling soil is an important step of tall grass plantation, can facilitate the operations such as later stage farming, sowing, irrigation, draining, fertilising, laxative, pruning.
(2) lay netted filling drainage pipeline net: adopt closed drainage technology, on soil after step (1) leveling, ditch and lay water pipe, irrigation pipe, draining are oozed to adjacent parallel the burying underground of Guan Tonggou, pipe end ratio falls and is 1/500-1/1000, after pipe laying, backfill is closely knit, concentrates leveling;
(3) lay sand bed: the fine sand of evenly laying 20 cm thicks on the soil of step (2) leveling;
(4) lay fertilizer layer: on the sand bed of laying in step (3), evenly laying a layer thickness is the fertilizer of 2-3 cm thick, can be directly to tall grass supply nutrient component;
(5) sowing: adopt unrestrained mode of spreading to sow high wool grass seed, flat with flat rake holder, cover straw mat, spray water every day 4-5 time, keep straw mat moistening, carry out maintenance, until little grass is emerged;
(6) strong sprout: little grass is taken straw mat off after emerging, utilize the time of 10-14 hour to complete strong sprout, then continue every day and spray water 3-4 time, keep sand moistening, impel the prosperous length of seedling.
(7) cut grass and fertilising: grass meeting heading in the time that tall grass grows to 8-10 centimetre high, affect tall grass later stage growing way, need cut in time grass, be advisable in the 5 centimetres of left and right of height that keep careless while cutting grass.Fertilising in every 20 days once;
(8) maintenance: note tall grass Diseases of Turfgrass and insect pest summer, should spray in time sterilizing insect-killing medicine; Spray water twice every day in summer, each half an hour; Spring and autumn sprays water one to secondary every day, and each 20 minutes, the front lawn that freezes winter must on average spread husky 3 centimetres again, in order to avoid suffer freeze injury.
The degree of depth of the described ditch of step (2) is 50-80 centimetre, and width is 50 centimetres, and pipe network spacing a, b are 9 meters.
Irrigation pipe and draining are oozed pipe using running water as water source, and irrigation pipe is aided with booster pump and carries out sprinkling irrigation, and sprinkler spacing arranges according to the water spray diameter of shower nozzle, realizes seamless irrigation.
Described draining is oozed pipe outside and is evenly enclosed with outsourcing filtrate, described outsourcing filtrate the osmotic coefficient 10-20 that is outside alkaline land soil doubly, adopt underground drainage to ooze pipe and carry out draining, can mandatory down phreatic low, make alkaline land soil quick desalination, dealkalize, guarantee that tall grass root system is not subject to saline and alkaline harm.
The described fertilizer of step (3) is the residue after farmyard manure, house refuse, rotten plant, cultivated mushroom.
The described sowing of step (5) is at irrigation pipe, sand bed to be irrigated, and humidity is carried out while meeting tall grass growing environment.
Step (6) process in described strong sprout in the afternoon 18:00 is taken straw mat off later, utilizes strong sprout time in the evening.
The invention has the beneficial effects as follows: pass through to fill with drainage measure at beach saline land, coastal waters band, lowering of watertable, make the dealkalize of soil fast dewatering, reach the environment of suitable tall grass growth, technology provided by the invention can be used for the saline and alkaline regional golf range of high concentration, golf course, the place Urban Greenings such as football pitch, also can be used for saline and alkaline ground of high concentration, strand urban lawn afforests and beautifies and tide wall, reservoir grassed slope, simultaneously, for improving the ecological environment, extensive improvement saline land, increase grainfield area, alleviation urban land and basic farmland are striven ground contradiction extremely important effect.
