Abstract
The invention discloses a planting method for vetiver-grass heading and seed setting, relates to the planting method for allowing vetiver grass to grow seeds with the reproductive capacity, and belongs to the technical field of biological engineering. The planting method is characterized in that ingredients of planting soil comprise 0.2 g/Kg-0.5 g/Kg of total phosphorus, 5 mg/kg-10 mg/kg of rapidly available phosphorus, 0.4 g/Kg-0.8 g/Kg of total nitrogen, 0.5 mg/kg-25 mg/kg of alkali-hydrolyzale nitrogen, 15 mg/kg-25 mg/kg of rapidly available potassium and 5 g/Kg-10 g/Kg of organic-matter raw soil; planting land is subtropical climate, and the elevation is 1,700 m to 1,900 m; the full-year illumination time is 2,100.5 hours to 2,500 hours, and the perennial extreme low temperature is larger than or equal to -5 DEG C. According to the planting method, selection of natural factors in the vetiver-grass planting growth process is reasonable, vetiver grass is capable of growing seeds with the reproductive capacity, and possibilities are provided for large-scale production of vetiver-grass seeds.
Description
Technical field
The present invention relates to allow Caulis Miscanthis floriduli grow the implantation methods with fertility seed, belong to technical field of bioengineering.
Background technology
Caulis Miscanthis floriduli, has another name called Vetiveria zizanoides；As its name suggests, Yin Qigen is the most fragrant, therefore named Caulis Miscanthis floriduli, is the herbaceous plant that grows thickly for many years of a kind of grass family.Vetiveria low compensation (C4) plant, photosynthesis is strong, with regard to germination and growth during Wen Da 10 DEG C.Owing to this plant has the biological property of uniqueness, its effect in water and soil conservation is gradually shown up prominently.People are observed by cultivation subsequently, it is found that it has extremely strong annidation and degeneration-resistant (non-irrigated, wet, cold, hot, sour, alkali etc.) ability, and growth is rapidly, well developed root system, easily plant advantages such as easily living, have " herbaceous plant in the world with the longest root system ", the title of " magical herbage "；It is classified as the plant that preferably conserves water and soil by more than 100 countries and regions in the world.
But since the mankind start understanding and utilize Caulis Miscanthis floriduli, have been used up asexual propagation i.e. tiller Reproduction methods to carry out the breeding of Caulis Miscanthis floriduli.Generally believe that Caulis Miscanthis floriduli is not set seeds both at home and abroad, it is impossible to carry out seminal propagation.Therefore, at present, there is not yet the report of this type of technology both at home and abroad, so Caulis Miscanthis floriduli is difficult to implement in using extension process.Therefore; by natural factor natural factors such as () soil constituent, height above sea level, illumination in manual intervention Caulis Miscanthis floriduli plantation growth course; Caulis Miscanthis floriduli is allowed to grow the seed with fertility; to strengthen accelerating popularization and the utilization of Caulis Miscanthis floriduli greatly, the large-scale production for Caulis Miscanthis floriduli seed provides possible.
In disclosed Vetiver-seed propagating method patent, Caulis Miscanthis floriduli seed is locality Wuchuan City, Guangdong Province, China's Caulis Miscanthis floriduli unique original producton location, it is naturally produced Caulis Miscanthis floriduli base, at present in the case of artificial growth Caulis Miscanthis floriduli, not yet has the report as seminal propagation of the Caulis Miscanthis floriduli knot.
Summary of the invention
The technical problem to be solved is to provide a kind of implantation methods allowing Caulis Miscanthis floriduli heading set seeds, its operational approach is simple, natural factor in the Caulis Miscanthis floriduli growth course selected is reasonable, and Caulis Miscanthis floriduli can be allowed the most in high volume to grow the seed with fertility.
Solve the technical scheme that technical problem of the present invention taked as follows: the composition of planting soil is full phosphorus 0.2～0.5g/Kg, rapid available phosphorus 5～10mg/kg, full nitrogen 0.4～0.8g/Kg, alkali-hydrolyzable nitrogen 0.5～25mg/kg, available potassium 15～25mg/kg, the raw-soil of organic 5～10g/Kg；Planting site elects subtropical climate, height above sea level 1700～1900m as；The annual illumination time is 2100.5～2500 hours, long-term extreme low temperature >=-5 DEG C.
The Caulis Miscanthis floriduli of plantation selects annual above Caulis Miscanthis floriduli, waters 4～6 times after field planting, and after field planting, in 18 months, period stem and leaf keeps nature growth, and the Caulis Miscanthis floriduli seed collection time is annual November.
The concrete implantation methods of Caulis Miscanthis floriduli of the present invention is: 1. Caulis Miscanthis floriduli every clump is 6～10 strains, before plantation, stem and leaf is trimmed to 14～16cm, root pruning to 5.5～6.5cm, then soaks Caulis Miscanthis floriduli root 50～70 minutes with the root-growing agent of dilution 100 times；2. rirgulaea is planted away from for 15～25cm, line-spacing 40～70cm；3. carbamide is used once by 30kg/ mu after surviving, at Caulis Miscanthis floriduli, 3 months turned green；4., after Caulis Miscanthis floriduli plantation survives more than 18 months, Caulis Miscanthis floriduli seed after annual November, is collected；6. after the Caulis Miscanthis floriduli seed after gathering dries in the shade, equal warm water soaking 2 hours, program request can breed Caulis Miscanthis floriduli seedling.
The method have the benefit that: carried out selecting rationally to the natural factor in Caulis Miscanthis floriduli plantation growth course; therefore Caulis Miscanthis floriduli can be allowed to grow the seed with fertility; large-scale production for Caulis Miscanthis floriduli seed provides possibility, solves the artificial technical problem using Caulis Miscanthis floriduli seed high-volume plantation Caulis Miscanthis floriduli and producing the seed with fertility.
