Description
Technical field
The present invention relates to a kind of method of converting cold season lawn into seashore paspalum lawn, be specifically related to a kind of habit of growth, cold-season type lawn is converted to the method for seashore paspalum lawn gradually naturally, belong to the afforestation construction field according to lawn plant.
Background technology
Cold-season turfgrass (English ryegrass, kentucky blue grass, Festuca Arundinacea, creeping bentgrass etc.) cold resistance is better at present, but its heat resistance is relatively poor relatively, under the hot and humid condition of the most of Area during Summer of China, it is incompatible obviously to show growth, a little less than the growth potential, disease is serious, and quality descends, even dead, had a strong impact on the view and the function on lawn.In addition, cold-season type lawn is had relatively high expectations to maintenance management, needs frequent pruning, fertilising, irrigates, prevents and kill off control measures such as disease pest and weed and just can keep certain turf quality.It is cold-season type lawn that there is quite high ratio on the lawn, urban green space that present China builds up in weather intermediate zone area, because the maintenance management level is difficult to satisfy the requirement of these cold-season type lawns, turf quality and functional deterioration are more serious, need convert the warm-season turf that suitable natural disposition is good, can adapt to extensive maintenance to.
Seashore paspalum belongs to the C4 plant, can normal growth under 10-40 ℃ of temperature condition, its optimum growth temperature is at 25-30 ℃, summer well-grown, to the better resistance of damage by disease and insect.And mainly with the form growth of ground stolon, the intergrowth of stolon can form extremely firm network structure on ground to seashore paspalum, and this also makes weeds be difficult to growth to a certain extent.
The method that present cold-season type lawn converts warm-season turf to mainly is " lawn reconstruction " pattern.That is: original cold-season type lawn is thoroughly rooted out or killed, plough soil again, sow or sod turf again behind the bed of smooth level ground.This method has following shortcoming:
1) new and old lawn is changed one period tangible interval, and the lawn has lost all ecological functions during rebuilding, and soil is exposed, causes water and soil loss easily;
2) cost height.The lawn rebuilds the cost that not only needs to spend new lawn, also will add the cost on the old lawn of thorough removing, and is more taller than the expense on newly-built lawn.
Summary of the invention
The objective of the invention is to wretched insufficiency and defective at existing lawn translative mode, provide a kind of cold-season type lawn to convert the method for seashore paspalum lawn gradually to, utilize the natural characteristic of lawn growth, make the lawn can under daily maintenance management, can realize the nature conversion.
For realizing such purpose, the present invention utilizes the cool-season grasses heat resistance relatively poor, in the more weak natural characteristic that enters summit of growth in summer with seashore paspalum of growth potential in summer, in the cold-season type lawn in spring, carry out bunch planting or drilling seashore paspalum kind stem, after planting irrigate, keep ground moistening, survive until seashore paspalum kind stem, the prosperity that utilizes seashore paspalum the to have growing ability of crawling, progressively capture the cold-season type lawn space left because of growth slows down, process along with summer high temperature, the cold-season type lawn growing way weakens gradually, lawn density progressively descends, seashore paspalum kind stem under the new sowing is grown gradually, expansion, seashore paspalum is by its extremely strong competitive advantage, and its stolon is is progressively occupied the space between the original cold-season type lawn plant, even cover on the cold-season type lawn plant, progressively close down the growing space of cool-season grasses, and produce a kind of environment of damp and hot closing, cool-season grasses is degenerated under the environment of this closing gradually, even it is dead.By this natural growth competition, the cover degree of cold-season type lawn reduces gradually, and the seashore paspalum lawn cover degree increases gradually, finally is entirely seashore paspalum and captures, thereby realize by the fully conversion of cold-season type lawn to seashore paspalum lawn.
The present invention includes following concrete steps:
1) seashore paspalum lawn that will turn green is dredged grass with thin careless machine, and the grass blade stem section that contains stipes that collection is dredged out is standby as kind of stem; Perhaps the seashore paspalum lawn that will turn green with the turf machine trips out, and after the flushing grass blade is cut into the stem section that contains stipes, and is standby as kind of stem;
2) prior to seeding original cold-season type lawn is carried out low the pruning 1-3 times, the lawn height after low the pruning remains on 10-30mm;
3) after the low pruning of cold-season type lawn, cold-season type lawn is carried out the perpendicular cuts operation, depth of cut is 20-30mm, and the cutting spacing is 4-6cm; Perhaps cold-season type lawn is punched, the punching degree of depth is 30-80mm, and pitch of holes is 5-6cm;
4) insert seashore paspalum kind stem in the soil joint-cutting that after the perpendicular cuts of lawn, stays continuously and carry out drilling; One section seashore paspalum kind stem of vertical insertion carries out bunch planting in each hole of perhaps beating on the lawn;
5) mulching soil on the ditch millet kind stem by the sea, or spread husky operation with sand-paving machine, the THICKNESS CONTROL of shop sand or mulching soil makes seashore paspalum kind stem have at least 1 stipes to basset at 5-8mm, compacting then makes the seashore paspalum kind stem of sowing closely contact with soil;
6) after planting irrigate, keep ground moistening, the axillalry bud on seashore paspalum kind stem grows and forms the ground stolon, finishes the conversion from the cold-season type lawn to the seashore paspalum lawn.
Described kind of stem is that 20-150mm is long, contains 1-4 stipes.
The degree of depth of described thin grass is controlled at 5-30mm.
Described cold-season type lawn is tall fescue turf, perennial ryegrass, kentucky bluegrass turf or the bent grass lawn of crawling.
Among the present invention, after seashore paspalum kind stem survives, can crawl to grow, since with original cold-season type lawn competitive growth in preponderate, along with the arriving in summer and the rising of temperature, the cold-season type lawn growing way weakens gradually, the seashore paspalum growing way strengthens gradually, the ratio of two kinds of grass seeds in the lawn changes, from original cold-season type lawn progressively to the seashore paspalum lawn transition, transition through 3-4 months, it is occupied that cold-season type lawn has been entirely seashore paspalum, the stolon on seashore paspalum ground has formed complete lawn and has covered, and has closed down the growing space of cool-season grasses with its good growing way, thereby realizes by the fully conversion of cold-season type lawn to seashore paspalum lawn.
The advantage that the inventive method is changed naturally:
1) new and old lawn conversion does not have interval, and the transition period turf quality is stable, is difficult to aware the variation on lawn on the view;
2) ecological functions on transition period lawn, leisure function are unaffected; Just because the grass seeds difference is slightly variant on the color of lawn;
3) expense is low.Only need to increase the cost of labor of grass blade and plantation grass blade, expense is rebuild far below the lawn.
