Abstract
The invention belongs to the technical field of pretreatment of seed germination and discloses a method for increasing emergency rate of persimmon seeds. Emergence of seeds is promoted by variable-temperature treatment, seed disinfection, wet sand wrapping and the like, emergence time is shorted, and the purposes for seedling orderliness and robustness and high emergence rate are achieved.
Description
Technical field
The invention belongs to plant seed germination pretreatment technology field, be specifically related to a kind of method that effectively can improve persimmon percentage of seedgermination.
Background technology
Persimmon (Diospyros kaki Thunb.) originates in the planting fruit-trees that China is now distributed widely in China's the South and the North, have the laudatory title of " woody grain; iron crops ", its economic life reaches a century, having saying of " plantation in a year; century-old income ", is a kind of important economic fruit tree.Persimmon fruit has very high nutritive value, and it contains abundant carotin, V
c, glucose, fructose and the mineral matter such as calcium, potassium, persimmon is classified as the eighth-largest best fruit in the world in 2006 by the World Health Organization.In addition, persimmon is strong compared with the cultivation adaptability of other fruit trees, and damage by disease and insect is few, extensive management, high financial profit, by numerous growers are liked.In recent years along with the popularization of sweet persimmon, China's persimmon area under cultivation is in expanding year by year.
But persimmon seed is large, plant skin depth and hard, directly after planting deposit that the germination cycle is long, germination rate is low, irregular phenomenon of emerging.Xu Changbao etc. study discovery, exist in persimmon seed coat and suppress the material of seed germination, contrast percentage of seedgermination is 10.5%, and artificial removal plants micromicro and makes germination period shift to an earlier date 9 days, germination rate brought up to for 65.0% (Xu Changbao etc., " forestry science and technology exploitation " the 23rd volume the 2nd phase in 2009).But for Production of Large Fields, artificial removal's seed coat is time-consuming, inconvenience is promoted.
Because the demand of persimmon is increasing year by year, therefore amount reproduction nursery stock has important economic benefit, social benefit and ecological benefits.By effective method, carry out presprouting of seeds easily, improve percentage of seedgermination and survival rate, this seems particularly important.
Summary of the invention
For current persimmon after planting germination rate low, germination cycle long, uneven present situation of emerging, the object of the present invention is to provide a kind of with low cost, simple and easy to do, method of being easy to raising persimmon percentage of seedgermination and the regularity promoted.
In order to realize object of the present invention, inventor, by lot of experiments research also persistent exploration, finally obtains following technical scheme:
Improve a method for persimmon percentage of seedgermination, the method comprises the steps:
(1) spring, full unabroken seed is chosen;
(2) with 60 ~ 70 DEG C of hot-water soak seeds, do not stop to be stirred to water non-scald on hand, soak after reaching 8 ~ 10 hours and pull seed out;
(3) seed is put into 10 ~ 15 DEG C of cold water to soak 12 hours, pull out and drain placement 12 hours;
(4) step (3) 2 times are repeated;
(5) use medicining liquid dipping seed, clear water is pulled out after rinsing and is drained;
(6) will rear seed be drained mix the wet sand of moisture content 15%-25%, and be put in shady and cool place, treat that seed exposes milky radicle, can sow.
Preferably, improve the method for persimmon percentage of seedgermination as mentioned above, in step (3) wherein, seed is put into cold water and soak, the water surface is advisable to exceed seed 5cm.
Preferably, improve the method for persimmon percentage of seedgermination as mentioned above, the thimerosal in step (4) is wherein 1000 times of liquid of 50% carbendazol wettable powder, and immersion seed time is 20 ~ 40min.
Compared with prior art, the inventive method is simple and easy to do, be easy to promote, and significantly shortens seed germinating time, improves percentage of seedgermination and Phase ofsprouting.

(4) step (3) 2 times are repeated, i.e. the 3 day time of whole cold water soak process lasts;
(5) carry out disinfection with 50% carbendazol wettable powder, 1000 times of immersion bubble seed 30min, clear water is pulled out after rinsing 3 times;
(6) will rear seed be drained mix the wet sand of moisture content about 20%, and be put in shady and cool place, check seed sprouting situation every day.Treat that seed fully absorbs water after 1 week, expose milky radicle, can sow.
Embodiment 3:
(1) spring, reject the seed of shrivelled shrinkage, choose 100, full unabroken seed;
(2) with 70 DEG C of hot-water soak seeds, do not stop to be stirred to water non-scald on hand, soak and pull seed out after 8 ~ 10 hours;
(3) seed is put into 15 DEG C of cold water to soak 12 hours, pull out and drain placement 12 hours;
