Abstract
The invention discloses a Tilia miqueliana seedling raising method, which includes seed collection, drying in the shade, soaking, multi-substrate variable temperature stratification and transplanting. Seedlings of Tilia miqueliana raised by the method break through dormancy in about 50 days, are high in survival rate and emergence percentage, and have developed roots.
Description
Technical field
What the present invention relates to is the seedling-cultivating method of tilia miqueliana.
Background technology
Tilia miqueliana (
Tilia miquelianaMaxim1.) deciduous tree, the height of tree reaches 20m, belongs to the Tiliaceae Tilia, originates in each province, East China, east, Hunan, Guangdong, gives birth in hillside, gully woods.Timber can be done farm implements, furniture etc.; The stem hide fiber can synthetic cotton processed, is also good paper making raw material.Lime tree is beautiful with its leaf, and tree performance is quiet and beautiful, and summer, chrysanthemum was completely set, and is full of fragrance, can be used as shade tree, street tree, is also good nectariferous plant.Lime tree is one of the world four large street trees.But because Nanjing linden seeds has the deep dormancy characteristic, natural updating ability is relatively poor, and the long-term irrational excessive use of the mankind, makes these seeds face Critical Condition, has been listed in national secondary Precious, Rare, Endangered protective plant.
Through years of researches, found out at present the method for quick its dormancy of releasing, make its germinating time shorten to 60 days by original 3～5 years, such as (Wang Yinhua, the research of Nanjing linden seeds Mechanism of Dormancy, " Agricultural University Of Nanjing's paper ", 2007), even if but seed has been removed dormancy, the seedling percent of sprouting is lower, and the rear regularity of emerging is uneven.
Summary of the invention
The present invention is directed to existing deficiency provides a kind of seedling-cultivating method of tilia miqueliana.
The present invention realizes above-mentioned purpose by the following method.
A kind of seedling-cultivating method of tilia miqueliana comprises the following steps:
(1) gather ripe Nanjing linden seeds, physical purity of seed is 95%, and the thousand kernel weight of seed is 380g, and seed moisture content is 9%;
(2) seed that gathers is spread in the ventilation frescade, shady doing after 15-20 days first soaked the 50-55min sterilization with mass volume ratio 0.5% liquor potassic permanganate with seed, then use 60-70 ℃ hot-water soak 4-6 hour, naturally coolingly rinse seed with clear water and remove thimerosal residue and seed extract afterwards;
(3) many matrix alternating temperature stratification is processed: then evenly mix with seed with river sand, vermiculite, perlite, evenly spray again plant growth regulator, then put into seed packet, after seed packet is put into the incubator of 24-26 ℃ and is cultivated 4 days, take out seed packet, keep the skin wet and turn evenly, then seed packet being put into the incubator of 6-8 ℃ cultivated after 5 days, take out again seed packet, keep the skin wet and turn evenly, then the incubator of seed packet being put into 24-26 ℃ is cultivated, and seed begins to show money or valuables one carries unintentionally, and namely can be used for sowing;
Described matrix mixing quality ratio is river sand: vermiculite: perlite: seed=3:2:1:1; The consumption of described plant growth regulator is the 0.5-0.7% of seed weight, has mildew and rot seed in time to choose if find during turning; Described plant growth regulator is: gibberellin 70-90ppm, heteroauxin 50-60ppm, surplus are water;
(4) chitting piece is seeded on seedbed in the greenhouse, control temperature at 16-18 ℃, the serve as reasons composition of following weight portion of the matrix in described seedbed forms: 3 parts of 40 parts of the rice chaffs that fully ferments, 450 parts of humus soil, 7 parts of garden moulds, 0.08 part of carbendazim, 3 parts of perlites and river sands, after the aforementioned proportion mixed-matrix, spray matrix, every square metre of soil formalin 30m1 with after 60 times of formalin dilute with waters;
(5) when seedling grows to 6-8cm, can be transplanted to the land for growing field crops.
Beneficial effect
The present invention has the following advantages:
1, seed dormant technology is broken in invention comprehensive utilization drying, immersion, growth regulator adjusting and the processing of many matrix alternating temperature stratification etc., the technology processed of many matrix alternating temperature stratification particularly, comprise the multiple matrix that adopted proper ratio and from high temperature to low temperature again the alternating temperature to high temperature process, make and utilize the seedling from seed of the tilia miqueliana that the present invention obtains just to break dormancy about 50 days, and survival rate and planting percent are high, well developed root system;
2, the Nanjing linden seeds that adopts the present invention to process, when improving germination rate, the disposal cost of having saved again seed has solved simultaneously that seed sprouting is slow, irregular deficiency of emerging, make the tilia miqueliana of the difficulty of originally growing seedlings breed become simple, quick, more easily promote aborning;
3, the lamination matrix prepared of the present invention, increased the gas permeability of matrix, and then be conducive to the breathing of seed, therefore, accelerated the broken dormancy process of Nanjing linden seeds.
Embodiment
The present invention is further illustrated below in conjunction with embodiment, and following each embodiment only is used for explanation the present invention, to not restriction of the present invention.
