Abstract:The climate of the basin surrounding Wuyi mountain scenic area is the subtropical climate. Period of safety growth of rice is 235d and the accumulated temperature is 5368℃, so it can be double crops in a year. The quantity of heat for planting high-yield late-maturing hybrid rice varieties showed more than single crop but less than two crops. Timely early sowing can modulate the flower filling period of single cropping rice and the first crop of ratoon rice to match high value period of light and temperature in July and August, make the second crop to avoid chilling damage of early autumn. This is a key countermeasure for increasing rice production and income. Corresponding high-yielding cultivation techniques of rice include the selection of good cultivar, rational fertilization and water management, the promotion of mechanized production, and prevention and control of diseases, insect and weed.
