Abstract
The invention provides a method for increasing the emergence rate of gloriosa lily seeds. The method comprises the following steps: firstly, harvesting the seeds, and removing the outer red skins of the seeds; secondly, immersing the seeds in hot water, and then immersing the seeds in water at normal temperature; sowing the seeds on a seedbed evenly after the seedbed is well treated, covering the seedbed with peat soil or humus soil, building an arch shed on the seedbed, covering a sunshade net on the arch shed, and controlling the humidity and the temperature of the arch shed until the emergence of the seedlings. The method can achieve a remarkable emergence rate and uniformity greatly higher than those of conventional treatment, and besides, after the seeds, which are treated by heat shock, are sowed under different conditions, the emergence rate of the seeds subjected to thin-film and sunshade treatment is higher than that of seeds subjected to other treatment. The method can simplify the normal management process, the emergence of seedlings is regular and concentrated, the method is convenient for centralized management of cultured seedlings, the seed utilizing rate is improved, and the producing cost is reduced.
Description
Technical field
The present invention relates to a kind of method that improves good blue lily seed germination rate and regularity, especially a kind of method that shortens good blue lily seedling-growing time, accelerates the production of piece root, platymiscium culture technique field.
Background technology
Good blue lily (Gloriosa superba Linn) belongs to the good Cymbidium of Liliaceae, originates in Yunnan Province of China south, Hainan Province and Tropical Asia and Africa.Wild fragmentary distribution is arranged below the height above sea level 1200m of Yunnan Province of China Xishuangbanna, is a kind of perennial herbage flower of climbing up by holding on to type, having ornamental value; Because being rich in colchicin, its piece root is also the desirable feedstock of producing colchicin, the colchicin that China uses at present is by import, lack raw material and produce colchicin, through calculating current commercially available colchicin 120,000～150,000 yuan/kg, every mu can be produced 100～150g colchicin, amounts to the income that can arrive 1.2 ten thousand～1.5 ten thousand yuan/mu, is a medicinal plant that economic benefit is very high.Good blue lily is mainly cultivated two kinds of method breedings with seed and tissue, but comparatively economical with seminal propagation.Good blue lily easily bears seeds after pollination, and seed is more; In seeding process, because kind of skin is harder, thick, seedling-growing time is long, irregular, germination rate is lower, the good blue lily large-scale production of serious restriction.By consulting the related data of good blue lily research, the breeding research of good blue lily relates generally to organizes the cultivation aspect, for the research that improves the seed germination rate aspect, there is not yet report.
Summary of the invention
The piece root production problems such as, seedling-growing time low for good blue lily seed germination rate is long, the invention provides and a kind ofly by raisings, praise blue lily seed germination rate, and the shortening seed sprouting time, the method for blue lily piece root growth is praised in quickening.
The present invention completes by following technical proposal: a kind of method that improves good blue lily seeding ratio is characterized in that through the following step:
A, when the withered cracking of good blue lily capsule, take out seed and dry, remove the red skin of skin of seed;
B, the seed of steps A is placed in to hot water soaks 5～15 seconds, then be placed in normal-temperature water and soak 24～48 hours;
C, water after first seedbed soil being smash carefully, being flattened permeablely, then the seed after step B is soaked evenly is sowed on seedbed, is covered to thickness with peat soil or humus soil and reaches 0.5～1cm, rewaters to peat soil or humus soil humidity;
D, on the seedbed of step C, take shed, covered with sunshade net on shed, control in shed humidity and be 50～70%, temperature is 25～30 ℃, until emerge.
The hot water of described step B is the water that temperature is 75～85 ℃.
In described step D, the width of shed, ceiling consistent with the seedbed width is 0.5～1.0 meter apart from the height of seedbed face, surface coverage 10～15mm thick without dripping a film, mainly play moisturizing, heating effect.
In described step D, sunshade net is commercial black or silvery white sunshade net, and its obscurity is 60～70%, mainly plays temperature in the adjusting shed and is difficult for too high effect.
The present invention has following advantages and effect: adopt such scheme, first in hot water, soak seed (heat shock), can make good blue lily seed do sth. in advance two weeks emerges, and emergence rate 70～80% in 1 first quarter moon, and conventional 1 wheat harvesting period of not processing by heat shock just starts to emerge, and be only 45.6% at the emergence rate in 3 months of emerging; The emergence rate that heat shock is processed and regularity, all than significantly improving of not processing by heat shock, can be simplified the step of lifting the film moisturizing in the Routine Management process, emerge comparatively neat, concentrated, the centralized management of being convenient to grow seedlings, improved seed efficient, reduce production costs.
Embodiment
Below in conjunction with embodiment, the present invention is described further.

The present invention, by following test, further proves its effect and advantage:
While one, adopting conventional method to be emerged cultivation to good blue lily seed, its emergence rate and seedling-growing time are shown in Table 1:
Table 1 is processed the impact on good blue lily seed sprouting without heat shock
While two, adopting method provided by the invention to be emerged cultivation to good blue lily seed, when selecting different temperatures and time to carry out heat shock, its emergence rate and seedling-growing time are shown in Table 2:
The impact on good blue lily seed sprouting is processed in the heat shock of table 2 different temperatures and time
While three, adopting method provided by the invention to be emerged cultivation to good blue lily seed, when selecting uniform temp and time heat shock, different condition to sow, its emergence rate and seedling-growing time are shown in Table 3:
The impact of different condition sowing on good blue lily seed sprouting after table 3 heat shock
Four, conclusion:
From table 1, table 2, can find out, heat shock of the present invention is processed has remarkable result to good blue lily emergence rate, the good blue lily seed of processing through heat shock is done sth. in advance two weeks than processed conventionally good blue lily seed and is emerged, and 1 first quarter moon emergence rate just reaches 70～80%, and conventional method only had 45.6% emergence rate in 3 months.Therefore, suitable hot water (75～85 ℃) and processing time (5～15 seconds) truly have the water absorbing capacity of softening good blue lily outer covering of the seed duricrust, raising kind of skin, and then activate active substance in seed, accelerate sprouting of seed plumule.
Although good blue lily seed is processed positive effect is arranged heat shock, the good blue lily seed sprouting of sowing under the varying environment condition after heat shock is processed also plays a key effect.As can be seen from Table 3, in 1 first quarter moon, film (without dripping film)+sun-shading emergence rate is up to 82.2%, is secondly that film covers processing, and emergence rate is 63.3%, and the emergence rate covered without film is minimum is 56.7%.Therefore, temperature after planting, moisture management are also very important, and too low all can the impact of excess Temperature and humidity praised emerging of blue lily seed.
