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.Yunnan Province of China Xishuangbanna height above sea level 1200m has wild fragmentary distribution below, 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 is at present 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 seed coat 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 cultivation aspect, there is not yet report for the research that improves seed germination rate aspect.
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 one and praise blue lily seed germination rate by raising, shorten the seed sprouting time, accelerate the method for good blue lily piece root growth.
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, in the time of 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 seed after step B is soaked is evenly sowed on seedbed, is covered to thickness reaches 0.5～1cm with peat soil or humus soil, rewaters to peat soil or humus soil humidity;
D, on the seedbed of step C, take shed, covered with sunshade net on shed, controls in shed humidity and is 50～70%, temperature is 25～30 DEG C, until emerge.
The hot water of described step B is that temperature is the water of 75～85 DEG C.
In described step D, the width of shed, ceiling consistent with 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 and regulates arch temperature of shed to be 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 routine does not just start to emerge by 1 wheat harvesting period of heat shock processing, and be only 45.6% at the emergence rate in 3 months of emerging; The emergence rate of heat shock processing and regularity all, than not by the significantly improving of heat shock processing, can be simplified the step of lifting film moisturizing in Routine Management process, emerge comparatively neat, concentrate, 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.
Embodiment 1

The present invention, by following test, further proves its effect and advantage:
One,, while adopting conventional method to emerge 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
Two,, while adopting method provided by the invention to emerge cultivation to good blue lily seed, in the time 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
Three,, while adopting method provided by the invention to emerge 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:
Can find out from table 1, table 2, heat shock of the present invention is processed has remarkable result to good blue lily emergence rate, doing sth. in advance two weeks through the good blue lily seed of heat shock processing than processed conventionally good blue lily seed emerges, 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 DEG C) and processing time (5～15 seconds) truly have the water absorbing capacity of softening good blue lily outer covering of the seed duricrust, raising seed coat, and then activate active substance in seed, accelerate sprouting of seed plumule.
Although good blue lily seed is processed and had positive effect heat shock, under varying environment condition, sowing also plays a key effect to heat shock good blue lily seed sprouting after treatment.As can be seen from Table 3, in 1 first quarter moon ,+sun-shading emergence rate is up to 82.2% to film (without dripping a film), is secondly that film covers and processes, and emergence rate is 63.3%, and the emergence rate that covers without film is minimum is 56.7%.Therefore, temperature, moisture management are after planting also very important, and too low all can the impact of excess Temperature and humidity praised emerging of blue lily seed.
