Floating heeling in, be to utilize substrate automatic ink-suction loose in dish to the most saturated, moisture will not be too much, also will not be very few, significantly subtracts
Lack the generation of damping-off and root rot, thus improve seedling percent；4. wooden case cultivates seedling, when transplanting land for growing field crops, from case
In substrate on the seedling root system extracted can come off, after the sun is exposed to the sun, root tissue water status evaporation is big, and degree of injury is big；After transplanting
Foot need to be watered in time and determine root water, and need to water continuously 3-5 days；After transplanting, survival rate is low, only survives about 80%；Floating heel in then root
System can combine closely with hole mesostroma, when seedling is extracted from floating disc, extracts together with substrate, can reduce root system straight
The damage that connecing is exposed to the sun causes；Balled transplanting, the vitality restoration after root system is transplanted is fast, and drought-resistance ability is strong, and survival rate is high, up to 95%
Above；High by about 15% compared with the seedling field-transplanting survival rate that wooden case is cultivated；And floating disc is light, it is easy to carrying, can be by floating disc
It is transported to the edge of a field, then removes to plot, directly extract during transplanting and can transplant, more can reduce the evaporation of moisture, improve land for growing field crops and move
Plant survival rate.The floating method heeled in of this cane seedlings can serve sugar cane breed selection-breeding mechanism, for cane seedlings
Heel in cultivation.
