Abstract
KEYWORD: water and fertilizer managements; controlled irrigation; site-specific nutrient manage- ment; rice; phosphorus content; phosphorus accumulation; distribution ABSTRACT: Based on the data from field experiments, the phosphorus content and phosphorus accumulation of rice plants were analyzed, and phosphorus distributions in different parts of rice were studied as well. The results showed that compared with farmers' fertilization practice (FFP), site-specific nutrient management (SSNM) increased the phosphorus content of leaf under con- trolled irrigation, and the phosphorus accumulation of leaf was high in the end. At the same time, the phosphorus content of stem & sheath and roots were enhanced at jointing and booting stage, and the phosphorus accumulation of stem & sheath was increased as well. Also phosphorus content of panicle was higher than FFP at milk maturity stage. Compared with flooding irrigation, controlled irrigation reduced the phosphorus content of leaf and stem & sheath. However, the phosphorus con- tent of roots were improved with SSNM at jointing and booting stage, and the phosphorus accumu- lation under controlled irrigation condition recuperated at milk maturity stage. The phosphorus ac- cumulation of panicle was higher under water saving irrigation condition. Water and fertilizer managements promote phosphorus transferring under controlled irrigation and SSNM condition, and the phosphorus efficiency was improved as well.
