Embodiment
The invention will be further described below in conjunction with drawings and Examples.
As Fig. 1～shown in Figure 3, the strong sleep devices of Pharbitis purpurea seed of breaking of the present invention comprises friction box 1, goes up friction twitch-up 2, friction box 1 comprises friction box body 11, metal friction plate 12, friction box body body 11 edges extend upward box limit, three sides 111, a horizontal side does not have the box limit, is convenient to friction twitch-up 2 push-and-pulls friction hardseed, is convenient to topple over seed yet.Many rows that evenly distribute on the metal friction plate 12 hold the through hole 121 of seed, have so both effectively fixed seed, convenient again friction.Metal friction plate 12 is fixed on the friction box body, leaves the spacing of 4～6mm at the bottom of the box of metal friction plate and friction box body between the upside, can make the 1/5-1/4 of seed be exposed at through hole 121 tops, and the ratio of box body 11 length that rub and width is greater than 3.Last friction twitch-up 2 comprise base plate 21, with base plate 21 handles 22 connected vertically, base plate is fixed with sand paper 23 on 21 bottom surfaces.During use, seed is tiled between friction twitch-up 2 and the metal friction plate 12, last friction twitch-up 2 both sides evenly cover the weight 3 of 15kg～20kg, will go up friction twitch-up 2 and be pressed in reciprocating sliding friction twitch-up 2 on the seed, and it is strong to make equally distributed seed quicken to break seed under the weight friction.Strong for the ease of last friction twitch-up 2 push-and-pulls friction seed, the width B 1 of last friction twitch-up 2 is less than the inner width B of the box 11 that rubs, and the length A 1 of last friction twitch-up 2 is less than 1/3 friction box body length A; The push-and-pull distance of last friction twitch-up is 60cm～120cm.
The seed that present embodiment is selected for use is pale reddish brown Pharbitis purpurea kind, seed width 4mm-5mm, length 6-7mm.The method of breaking the strong dormancy of Pharbitis purpurea seed of present embodiment may further comprise the steps:
(1), seed selection
With the Pharbitis purpurea hardseed of results collection then, through selected, remove impurity, flat grain and damaged seed, standby;
(2), friction seed
Seed is sprinkling upon on the metal friction plate 12 equably, rocks the strong friction box 1 of seed, making in each through hole 121 of metal friction plate 12 all has seed, and the 1/5-1/4 of seed is exposed at through hole 121 tops.The strong friction box 1 of inclination seed is outwelled the unnecessary seed in top;
(3) will go up friction twitch-up 2 and be placed on seed top, last friction twitch-up 2 upsides evenly cover the weight 3 of 15kg～20kg, and friction twitch-up in the push-and-pull at the uniform velocity shows money or valuables one carries unintentionally seed and gets final product back and forth;
(4) upset friction box 1 is taken the seed that falls down from metal friction plate 12 away.
It is as follows to break the strong multiple processing mode of Pharbitis purpurea seed:
Handle 1: seed mixes through after the friction treatment;
After handling 2:98% concentrated sulfuric acid stirring seed soaking 15min, repeatedly sulfuric acid is rinsed well with running water immediately;
After handling 3:98% concentrated sulfuric acid stirring seed soaking 30min, repeatedly sulfuric acid is rinsed well with running water immediately;
After handling 4:98% concentrated sulfuric acid stirring seed soaking 45min, repeatedly sulfuric acid is rinsed well with running water immediately;
After handling 5:40%NaOH solution stirring seed soaking 15min, rinse well repeatedly with running water immediately;
After handling 6:40%NaOH solution stirring seed soaking 30min, rinse well repeatedly with running water immediately;
After handling 7:40%NaOH solution stirring seed soaking 45min, rinse well repeatedly with running water immediately;
Handle 8: after 15min is stirred in the hot water seed soaking in 80 ℃ water-bath, wash with running water;
Handle 9: after 30min is stirred in the hot water seed soaking in 80 ℃ water-bath, wash with running water;
Handle 10: after 45min is stirred in the hot water seed soaking in 80 ℃ water-bath, wash with running water;
Handle 11: behind the GA seed soaking 24h with 50mg/l, rinse well repeatedly with running water;
Handle 12: behind the GA seed soaking 24h with 100mg/l, rinse well repeatedly with running water;
Handle 13: behind the GA seed soaking 24h with 200mg/l, rinse well repeatedly with running water;
Handle 14CK: the seed that is left intact after selected.
(5) germination test
(BP) sproutung method carries out germination test on the employing paper, and the seed of above-mentioned every kind of processing is established 4 repetitions, and each repeats 50 seeds.Seed places in the 12cm glass culture dish, germinating bed is the paper bed, covers one deck filter paper on the seed, and duration of test keeps the interior filter paper of germinating bed moistening, test is carried out in constant incubator, 28 ℃ of temperature, 10h illumination every day, duration of germination carries out a detection record germination grain number to seeds germinated every day, and the corrupt blind seed number of record at any time, seminal root is designated as germination when reaching the length of seed own, counts for the first time the 2nd day, and last was counted the 20th day.The average germinative number of four repetitions of statistical computation, germination rate, hard seed rate and blind seed rate.
The germination of 14 kinds of different disposal the results are shown in following table:
As the histogram of Fig. 4 as can be seen, after method of the present invention is handled, seed germination rate brings up to 96% by original 18%, the seed hard seed rate drops to 4% from 82%, and this method has effectively been broken the strong of Pharbitis purpurea seed, has significantly improved percentage of seedgermination, short with other the processing method germinating time of comparing, it is neat to germinate, and seed is not had injury, no blind seed.
In addition to the implementation, the present invention can also have other embodiments, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of requirement of the present invention.
