Title
Effect of the Irrigation with Water Polluted by Diesel Oil at Two Rice Gr owth Stages on Rice Yield
Jinhu Wang Journal of Suzhou Railway Teachers College 2002
Other claims from this paper (5)
- Intervention effect Rice irrigated with diesel-polluted water at two growth stages yielded less than rice without diesel pollution.
- Intervention effect Yield loss from polluted water at the tillering stage was greater than at the ear primordial stage.
- Intervention effect At medium and high concentration (200 and 400 mg/kg soil) the yield difference between the two growth stages was significant (p0.01).
- Mechanism The yield decrease at the tillering stage is mainly caused by a decrease in biological yield.
- Mechanism The yield decrease at the ear primordial stage is due to a decrease in harvest index.
