Description
Technical field
The invention belongs to horticultural field, and in particular to a kind of method for culturing seedlings of Pyrethrum.
Background technology
Pyrethrum is the herbaceos perennial of Compositae.Half meter high is there are about, and the pinniform of many drastic cracks is extracted out from the base portion of stem
Greenery, head inflorescence as Herba Dendranthematis indici is clustered round among greenery, the central authorities of inflorescence have the flower of the thin tube-like of yellow, periphery
Inlay the pure white ligule petal of a circle.Seem, it is simple and elegant and unique, there is higher ornamental value, wherein the pyrethrin for containing
Mainly make agricultural fungicidess.But such a integrate view and admire with medicinal plant use the seed seedling-raising time it is long, emerge
Rate is not high.
The content of the invention
It is an object of the invention to provide a kind of method for culturing seedlings of Pyrethrum, substantially reduces the seed seedling-raising time, while carrying
The high emergence rate of seed.
The present invention is achieved through the following technical solutions：
A kind of method for culturing seedlings of Pyrethrum, comprises the following steps：
（1）Nutrition Soil is prepared, is counted by weight, comprising the following raw material：Laterite earth 50-80 parts, sodium bicarbonate 5-8 parts, carbamide 3-5
Part, dalcium biphosphate 3-5 parts, rice chaff 3-5 part, obtain Dalmatian chrysanthemum seed Nutrition Soil after uniform mixing；The Nutrition Soil for having configured is put down
The soil layer that thickness is 5-10cm is paved into, and 500 times of Bordeaux mixture is sprayed on soil layer surface；
（2）It is poured in water after Dalmatian chrysanthemum seed is basked seeds 1 day, rejecting swims in the not plump kind on the water surface and kind of damaging by worms, Ran Houzai
The secondary operation for carrying out basking seeds 1 day, rejecting cur amounts to 3 times；The Dalmatian chrysanthemum seed that screening is finished uses the mass concentration of room temperature
The aqueous hydrogen peroxide solution immersion 8-10 hours of 0.5-1% cause；
（3）Using acetyl aminophenol, ethanol, sodium bicarbonate, water by weight 0.1:1:2:After 50 solution being configured to are to initiation
Dalmatian chrysanthemum seed carry out seed soaking operation, seed soaking time 20-30min keeps illumination, intensity of illumination to keep 200- during seed soaking
280lx；
（4）Using step（1）The Nutrition Soil is planted, and planting depth is 2-4cm, and 2 seeds are used per cave, spacing is planted
For 5*10cm, can not water on the same day during plantation, plantation poured a water after 2-3 days every 2 days, and when watering, use quality concentration is
0.2% urea water, using soil layer surface spray formula sprinkling method, is covered using plant ash on kind of plant hole top after watering；
（5）After emerging, thinning, weeding, insect prevention are carried out in time；Height of emerging is transplanted in 8-10cm.
Preferably, step（2）Described in Nutrition Soil, count by weight, comprising the following raw material：It is laterite earth 60-70 parts, little
Soda 6-7 parts, carbamide 4-5 parts, dalcium biphosphate 4-5 parts, rice chaff 4-5 part.
Preferably, step（2）Described in Nutrition Soil, count by weight, comprising the following raw material：70 parts of laterite earth, little Su
Make a call to 6 parts, 5 parts of carbamide, 4 parts of dalcium biphosphate, 5 parts of rice chaff.
Preferably, step（3）Described in seed soaking time be 25min.
Preferably, step（3）Described in illumination intensity of illumination be 240lx.
Beneficial effects of the present invention：The Nutrition Soil can for Dalmatian chrysanthemum seed sprouting provide needed for nutrient, contract significantly
The short seedling-growing time of seed, sprays 500 times of Bordeaux mixture to soil surface and can kill the antibacterial in soil, it is ensured that Pyrethrum
The emergence rate of seed；8-10 hours are soaked using the aqueous hydrogen peroxide solution of mass concentration 0.5-1% of room temperature to Dalmatian chrysanthemum seed
Cause, corrosion can be reached and planted skin, improved and sprout the activity of relevant enzyme, promote the effect of seed sprouting, while to removing with seed
Worm chrysanthemum seed plays significant sterilization effect, is further ensured that seed viability, promotes the sprouting of seed；And hydrogen peroxide point
Noresidue after solution, is a kind of extremely excellent seed priming medicament；Seed soaking is pressed using acetyl aminophenol, ethanol, sodium bicarbonate, water
Weight compares 0.1:1:2:50 solution being configured to, can further kill the surface of the seed and internal antibacterial, while sprouting for seed
Nutrient needed for providing；Illumination, intensity of illumination is kept to keep 200-280lx, the aerobic respiration of seed can be promoted during seed soaking, can
To greatly improve the speed of germinating and survival rate of Dalmatian chrysanthemum seed；95% is up to using the method nursery seed, seedling raise period is more existing
There is method to shorten 7 days, be a kind of effect is significant, be adapted to the Pyrethrum method for culturing seedlings promoted.
