The rice-Cnaphalocrocis medinalis (Guenee) system was studied based on the principles and methods of system sciences to seek possible ways or strategies for pest population control. A conceptual model describing interrelated activities among different generations of C. medinalis (Guenee) and their natural enemies was designed and implemented through differential equations...

Although rice canopy structure is a critical factor that influences rice yield and quality, few research has been conducted on the effects of rice-duck farming on rice canopy structure. Canopy structure characteristics at tillering and full-heading stages of late rice were compared between rice-duck farming and conventional rice farming (control)...

A field experiment was conducted to study effects of different rice-based cropping systems on diseases, pests and weed (DPW) hazards and yield of rice. The experiment included four treatments: conventional rice farming system (CR) as control, conventional Oenanthe javanica farming system (CO), conventional intercropping of rice with Oenanthe javanica (CRO)...

A significant progress had been made in the theory and practice of rice-duck farming in China in recent decades. Attained theoretic achievements include effects of rice-duck farming on: 1) nutrient cycle, matter and energy flow characteristics in paddy fields; 2) pest and disease control and the dynamic relationship between pests...
