Abstract

A research was carried out to determine the compensation effects of fertilization after water stress on all growth indexes of rice by pot and test-pit experiments. Results show that the fertilization can cause obvious compensation effects and shorten response time of compensation effects on all growth indexes of rice and increase the relatively rates on that of rice. The compensate rates of the growth of rice are faster fertilizing after light drought, but the compensate strength is weaker than doing after heavy drought. The promotion effects is optimal on all growth indexes of rice fertilizing after short-duration heavy drought and long-duration light drought at tillering stage.
