Description
Technical field
The present invention relates to a kind of warm season turf build and plant technology, particularly a kind of for warm season turf sexual propagation method large tracts of land floor space technology.
Background technology
The turf establishment method generally includes two kinds: a kind of is sexual propagation, and another kind is vegetative propagation.Sexual propagation refers to adopt the method lawn planting of direct seeding lawn seed, and vegetative propagation is that the planting of warm-season turf not only can be adopted the sexual propagation method but also can adopt asexual process by method lawn plantings such as seeding lawn stem or cultivation divots.In the afforestation in the past, the vegetative method of the many employings of planting warm-season turf, this mainly is because warm season grass seeds duration of germination is comparatively strict to the requirement of temperature, humidity and illumination, and in the production practices of afforestation, the large tracts of land lawn planting is difficult to control temperature and humidity, cause its germination rate and germination vigor to reduce, affect turf speed and turf quality.And the turf that the vegetative propagation of warm-season turf needs, almost all from wild resource, the turfgrass that lawn base provides is cold season (being subjected to the comparatively restriction of difficulty of warm season floor space).In recent years, country put into effect policy successively, in order to protect vegetation, to prevent erosion, forbade destroying natural resources, and this makes warm-season turf be hindered by the approach of asexual process lawn planting, had had a strong impact on the application of warm-season turf in afforestation.And most warm season turfs all have wild distribution in China from south to the north, the grass seeds resource is very abundant, the cold-season turfgrass that uses in the afforestation, its grass seeds more than 90% from external import, at present China needs the import turf grass species approximately about 3000 tons every year according to statistics, consumes the foreign exchange millions of dollar.And warm season turf mostly is the Local grass-seed of China, and various resistances and extremely well-adapted have the incomparable superiority of cold season (import grass seeds), occupy important position in afforestation.Utilize simultaneously seeding method floor space cost lower, turfgrass size uniformity, turf quality is better, is convenient to maintenance, the person's that deeply is subjected to the turf management welcome.Therefore the technological difficulties that solve warm season turf seeding method floor space are significant.
Summary of the invention
In order to address the above problem, the invention provides a kind of new technology of seeding method planting warm-season turf, technology of the present invention is applied in the large tracts of land planting engineering of afforestation warm-season turf, can significantly improve germination rate and germination vigor, promote seedling growth, shorten turf grass growing time, improve turf quality; And energy saving water resource and minimizing maintenance recruitment, make the maintenance management cost.
The technical solution used in the present invention is: a kind of planting and establishing method of warm-season turf comprises the steps:
(1) preparation in the front place of floor space:
1) soil melioration: making the soil texture is sandy loam or loam;
2) regulate soil pH value: make its pH value scope at 5.5-6.5;
3) soil cultivation: tilth is 35cm approximately;

2, pcnb 1-3 g/m
2
(2) floor space operation:
1) unwrapping wire: according to 3-5 rice width the place is separated into several sowing divisions with the rod rope;
2) fertilising: apply composite fertilizer, fertilizing amount is 50-70 g/ m
2Described composite fertilizer is MAP, diammonium phosphate, nitrogen-phosphorus-potassium compound fertilizer or fused calcium magnesium phosphorus potash fertilizer;
3) sowing: when minimum air temperature 8-10 ℃, sowing in the time of maximum air temperature 18-20 ℃;
4) for the first time suppression: the roller of 150-200kg is suppressed;
5) cover sand: the sieve with aperture 4-5mm covers sand, thickness 0.4-0.6cm;
6) for the second time suppression: the roller of 150-200kg is suppressed;
7) water: adopt atomizer to water, make the approximately ground moistening of 30cm of top layer;
8) overlay film: adopt agricultural white plastic mulching;
(3) remove the front management of film:
1) management in seeding stage: keep the interior temperature of mulch film at 26-35 ℃, relative moisture is kept about 90%, when temperature in the shed surpasses 35 ℃, waters water for cooling;
2) management that all sprouts of seedling: after planting, go out 1-2 seedling when every square centimeter, seedling is long during to 2 leaflets, a film; Described film is: enter branch in the mulch film underneath, mulch film propped, overhead the height 5-10cm, the branch spacing is 1m approximately; When the arid of the level ground bed topsoil 2-5cm in the mulch film, need to water;
(4) remove film: tiller, remove when cover degree reaches 80% left and right sides mulch film to having more than 3 when seedling in the film is long.
The invention has the beneficial effects as follows:
1) germination rate improves: the present invention is owing to providing the suitableeest temperature and humidity during seed sprouting, the rapid imbibition of seed, sprout, germinate, that has avoided that part seed duration of germination causes owing to the moisture supply is inadequate, inhomogeneous the bud phenomenon, thereby has improved germination rate.
2) germination vigor improves: the present invention is because the control temperature in the shed reaches 26-35 ℃, and relative moisture reaches about 90%, so seed germinating time is 5-7 days, and common planting method needs 8-15 days, and higher germination vigor is conducive to maintenance and the management in later stage.
3) shorten turf grass growing time: the raising of germination rate and germination vigor increases ahead of time germination and Seedling density and becomes a reality, and this itself has just shortened turf grass growing time.And seedling was subject to the protection of mulch film all the time before Cheng Ping; avoid heavy rain to the erosion of seedling; and remain optimum temperature and the humidity of growth of seedling, before the floor space fertilizer use the nutrient that has guaranteed that growth of seedling needs, white mulch film does not affect the illumination that growth of seedling needs in addition.Make warm-season turf at 40-50 days Cheng Ping, can shift to an earlier date at least 10 days Cheng Ping than common planting method.
4) avoid the risk of floor space failure: common planting method is not after planting covering or is adopting straw screen or mat to cover, and just there is the risk of floor space failure in this.If take the method that do not cover, during seed sprouting and growth of seedling, meet with the weather of moderate rain or heavy rain, will seed and seedling be flushed away owing to the impact of rainwater and the erosion of rainwash, floor space will be failed; If adopt straw screen or mat to cover, although temperature and the humidity that needs during the seed sprouting can be provided, can not satisfy the illumination of needs during seed sprouting and the growth of seedling, floor space can not be successful.The present invention adopts after planting covers sand, thickness is 5mm approximately, and use the method for plastic mulching in the above, both guaranteed during seed sprouting and the growth of seedling, can seed and seedling be flushed away owing to the impact of rainwater and the erosion of rainwash, the temperature and the humidity that need during the seed sprouting can be guaranteed again, needed illumination during seed sprouting and the growth of seedling can also be satisfied simultaneously.
5) improve turf quality: the raising of germination rate and germination vigor, lawn density is increased, and identical water, fertilizer and illumination condition effectively promote the seedling growth uniformity, all highly consistent from color, quality, density and homogeneity, thus turf quality is improved.
6) saving water resource: because from being seeded into during the growth of seedling until Cheng Ping, all the time by plastic mulching, the moisture loss of having avoided seedling evaporation and earth's surface transpiration to cause, having saved needs the large quantity of moisture that replenishes during seed germination and the growth of seedling, thereby has saved a large amount of water resources.
7) floor space cost: saving water resource, reduce the amount of labour used of frequently watering, shorten turf grass growing time, all make the floor space cost.
