主 题:hybrid rice varieties on-farm conservation rice monoculture traditional rice-fish farming
摘 要:The traditional rice-fish farming system is selected as a "globally important agricultural heritage system" (GIAHS) by the Food and Agriculture Organization (FAO),United Nations Development Programme (UNDP),and Global Environment Facility (GEF),*** Zhejiang Province of China,where the pilot site for this GIAHS farming system is located,we compared the use of traditional rice varieties in rice-fish co-culture and rice ***,we determined how traditional rice varieties were performed in this rice-fish *** 19% of the farmers who practiced rice monoculture planted traditional varieties while 52% of farmers who practiced rice-fish co-culture planted traditional *** varieties represented 13% of the total land cultivated under rice in the rice-fish system but only 2% in the rice monoculture *** the rice-fish system,yield was lower for traditional rice varieties than hybrid varieties but application of fertilizers and pesticides was also *** a field experiment in the rice-fish system without pesticides,rice planthopper numbers and sheath blight incidence were lower from three traditional varieties than one hybrid variety;yields were 8 to 32% lower from the traditional varieties than the *** results showed that traditional rice varieties can be preserved through conserving GIAHS rice-fish *** study also indicated that traditional rice varieties can survive in the rice-fish system because these varieties are helpful to the whole system and beneficial to the farmers.
