In Australia, there are about 2200 families
farming rice.
During July
and August, the land is prepared for the sowing in ------
. The land is separated into bays each about four hectares
surrounded by rice banks that keep sufficient water in. The
bays are all on a slope so that water can flow from one bay
to the other, making irrigation easier. To make the banks,
there are machines called disk bankers and the ground can
also be levelled using machines.
Sowing
The rice seeds
are sowed three ways:
1) Aerial
sowing: the seeds are soaked for 24 hours and drained for
24 hours so they can pre-germinate and shoot. Then they are
sown from and aeroplane into flooded bays. Each hectare of
land would require about 250kg of seed.
2) Combine
sowing: combine sowing sows the seeds with a combine or seeding
machine pulled by a tractor. These machines can dig a trench
for the seed, drop the seed in the hole along with fertiliser
and cover with soil.
3) Sometimes
the seeds are sown on pasture without removing the previous
crop. The left over plants are eaten to stubble by livestock
, burnt into the ground or eradicated herbicide. |
