Abstract
The invention discloses a method of using ottochloa nodosa to start a shade-tolerant lawn, which includes: soaking seeds of ottochloa nodosa with gibberellin 5-8mg/L for 14-16 minutes, mixing humic acid 15.0g per kilogram of the seeds, sowing the seeds of ottochloa nodosa into soil of a shaded region with a shading rate 30-90% according to a seed density 10-15g/m2, controlling water content of the soil to be 30.0% during seed germination, carrying out cultivation management after seed germination, and obtaining the lawn of ottochloa nodosa growing in the soil of the shaded region. The seeds of ottochloa nodosa are treated with both the gibberellin and the humic acid, soil water is also controlled during seed germination, and accordingly, germination rate and survival rate of the seeds of ottochloa nodosa can be increased evidently, the germination rate can reach above 90%, up to 95%, the survival rate can reach above 80%, up to 85%. Otherwise, the germination rate of the seeds treated with no gibberellin or humic acid only reaches 15% and below. After the seeds of ottochloa nodosa germinate, the lawn can be quickly formed by conventionally managing cultivation.
Description
Technical field:
The present invention relates to the planting and establishing method on anti-shady lawn in the construction of greenery patches, a kind of cities and towns, relate to a kind of method of utilizing the little liquid distilled from honeysuckle flowers or lotus leaves seed of shade tolerance grass seeds grass (Ottochloa nodosa (Kunth) Dandy var.micrantha (Balansa) Keng f.) to set up anti-shady lawn specifically.
Background technology:
Green grassland is the common greenery patches form of urban greening, absorption dust, purify air, fixation of C O
2And emit O
2, increase aspect such as landscape effect and have important function.The green grassland construction development in current China cities and towns is very fast.But anti-shady type lawn is set up few, and is also less at the grass seeds that the greenery patches sylvan life is used, and causes having formed under many arbors and the shrub weeds or baldness, and under overpass or the shady place of the building back of the body, also multiform has become bare land in addition.Wherein main reason is these local shadings that exist in various degree, and general positive natural disposition turf grass species is difficult to existence, has caused this class green grassland generally second-rate.For this reason, the build and plant technology of creating anti-shady lawn is very necessary.
Little liquid distilled from honeysuckle flowers or lotus leaves seed grass (Ottochloa nodosa (Kunth) Dandy var.micrantha (Balansa) Keng f.) is that grass family (Gramineae) reveals the mutation that the seed grass belongs to (Ottochloa), perennial herb; Another name Maraba Otto grass.Stalk is overgrow; The open and flat lanceolar of blade; Give birth on the panicle top, carries out; Small ear contains spends 2, and back of the body abdominal pressure is flat, whole the coming off in ripe back, grain husk be about into little spike length 1/2 or long slightly, first Xiao Hua is sterile, lemma is membranous closely isometric with small ear, and the 7-9 arteries and veins is arranged, the second little flower development, lemma is tough and tensile and thick, squamation is thin, and is folding, tool 5 arteries and veins; Style separates, the florescence 7-11 month.Be distributed in Asia and Oceania, produce ground such as Taiwan, Guangdong, Guangxi and Yunnan, also there are distribution in India, Malaysia.Give birth to mountain valley, woods limit wetland.
Summary of the invention:
The purpose of this invention is to provide a kind of seed germination rate and survival rate high, utilize little liquid distilled from honeysuckle flowers or lotus leaves seed grass to set up the method on anti-shady lawn fast and effectively.
Of the present inventionly utilize little liquid distilled from honeysuckle flowers or lotus leaves seed grass to set up the method on anti-shady lawn, it is characterized in that, may further comprise the steps:
The seed of little liquid distilled from honeysuckle flowers or lotus leaves seed grass was soaked 14～16 minutes with gibberellin 5～8mg/L, and the amount of mixing 15.0g by every kilogram of seed is mixed humus again, with 10～15g/m
2The density of little liquid distilled from honeysuckle flowers or lotus leaves seed grass seed broadcast sowing shading rate be 30～90% by in the soil in shading area, the moisture of control soil is 30.0% during seed germination, treat to carry out cultivation management behind the seed germination, little liquid distilled from honeysuckle flowers or lotus leaves seed grass just grows up to the lawn in by the soil in shading area.
Described by the shading area be meant some as by around the high building of shading, greenery patches sylvan life (containing bamboo grove) or the inferior area of overpass.
Before the sowing of little liquid distilled from honeysuckle flowers or lotus leaves seed grass, to being put in order ground, remove the weeds in the soil earlier by the soil in shading area, when soil was barrenr, first organic fertilizer was as base fertilizer.
Described treating carried out in the cultivation management behind the seed germination, and its lawn height dimension is held in 20～30cm, can reduce and prune maintenance cost more than 30%.
The present invention is by selecting to have extremely strong anti-shady ability, have the turfgrass of cold season and warm season concurrently, indigenous plant-little liquid distilled from honeysuckle flowers or lotus leaves seed grass conduct is at the grass seeds of being set up the lawn by the shading area, utilize this little liquid distilled from honeysuckle flowers or lotus leaves seed grass to have extremely strong shade tolerance, reach at shading rate under 90% the degree and still can keep normal growth, and easily plantation, easily survive, manageability, growth is rapid, and it is fast to cover the face of land, just can form the characteristics on fine and close lawn within a short period of time, with little liquid distilled from honeysuckle flowers or lotus leaves seed grass seed by gibberellin and humus in conjunction with processing, control the soil moisture during the seed germination again, can significantly improve little liquid distilled from honeysuckle flowers or lotus leaves seed grass seed germination rate and survival rate, germination rate is reached more than 90%, reach as high as 95%, survival rate reaches more than 80%, reaches as high as 85%, and the acid-treated contrast of gibberellin of no use and humic, its germination rate have only 15% and below, treat that little liquid distilled from honeysuckle flowers or lotus leaves seed grass seed is sprouted after, behind conventional cultivation management, moulding fast, general about two all lawns are just plastic.This lawn has extremely strong anti-shady ability, by the shading area, as well-grown around the city high rise building, under greenery patches sylvan life and the overpass.Adding little liquid distilled from honeysuckle flowers or lotus leaves seed grass all can sow or transplant throughout the year; Little liquid distilled from honeysuckle flowers or lotus leaves seed grass is acidproof, anti-thin, need not apply fertilizer basically in the lawn of institute's planting, and few damage by disease and insect takes place, thereby planting and management cost are all very low; Little liquid distilled from honeysuckle flowers or lotus leaves seed grass can arbitrarily not spread and come, and is autochthon yet, can not become injurious weed; Little liquid distilled from honeysuckle flowers or lotus leaves seed grass plant then keeps flat and crouches when sunny, shady when giving birth to state then plant be advantages such as clump shape growth.Therefore it is regional by the shading area to be fit to very much China south China and southwest (also may extend to Southeast Asia) etc., as around the city high rise building, have extraordinary application prospect under the greening forest belt at the bottom of the overpass and city.
