Rotation, and then the Reusability of the device can be convenient for.
Working principle: the screening plant of the resistance to deep germ plasm resource of rice first by this convenient for comparison is taken to experimental site,
And the suitable planting soil of different rice is chosen, and crush after soil is dried, then sieve by soil of the dusting cover to crushing
Choosing, Preparatory work of experiment work are just completed；
Then the measurement resistance to deep depth of rice is adjusted by the rotation ratch 11 of adjusting knob 7 so that ratch 11 drives as needed
Frame 12 moves up and down, so that same horizontally-arranged 3 inner bottom surface height of lower planting frame is incremented by or falls progressively in constant gradient, and makes same
The lower planting frame 3 inner bottom surface height of tandem it is identical (due to being provided with scale in groove 6, admittedly can directly pass through scale, by same cross
The lower planting frame 3 inner bottom surface height of row is arranged to constant gradient and is incremented by or falls progressively, and pawl 14 and ratchet 15 can turn ratch 11
Dynamic angle is fixed), the consistent seed that shows money or valuables one carries unintentionally of stalwartness of reselection difference rice is put into lower planting frame 3, so that same cross
The identical rice paddy seed of plantation in the lower planting frame 3 of row, and the rice seed for keeping the interior plantation of the lower planting frame 3 of same tandem different
Son, then sieving fine earth is filled into lower planting frame 3, until the upper surface of fine earth is flushed with the upper surface of upper planting frame 2, and root
According to the height of lower 3 inner bottom surface of planting frame, different amounts of water is sprayed in downward planting frame 3, in order to by bottom in lower planting frame 3
Soil is impregnated with, then on the apparatus with film covering, and the device is placed on to the people of 28 ± 2 DEG C of temperature, humidity 60% or so
Culture, so far, is just completed sowing of the different rice in different depth soil in work climatic chamber；
After sowing three days, the daily set time investigates emergence, and protrudes into lower depth measurement frame 5 by ruler after emergence and directly survey
It measures height of seedling (since the inner bottom surface of lower depth measurement frame 5 is flushed with the inner bottom surface of lower planting frame 3, admittedly can directly measure height of seedling), when one end
Between after, can directly observe the resistance to depth of same rice and the resistance to deep situation of different rice respectively by horizontally-arranged and tandem on the device,
Be conducive to intuitively screen rice；
If desired the device is resetted, it can be by lower position block 10, so that pawl 14 and ratchet 15 misplace, so that ratch
11 can rotate backward under the drive of lower planting frame 3, lower depth measurement frame 5 and conditioning box 12, to make lower planting frame 3 and lower depth measurement frame
5 drop to initial position, later, unclamp limited block 10, limited block 10 will under the action of compressed spring 13 outer bullet so that
Pawl 14 and ratchet 15 engage again, and the content being not described in detail in this specification belongs to known in professional and technical personnel in the field
