ProjectIntegrated Detection and Management of the Southern Rice Black-Streaked Dwarf Virus (Srbsdv) in Guizhou Province - TCP/CPR/3603 2020
Also available in:
No results found.In recent years, a new disease has been observed on ricein regions of Guangdong Province and Hainan Province,in southern China. The virus, known as the southern riceblack-streaked dwarf virus (SRBSDV), is transmitted to riceseedlings mainly by the white-backed planthopper,Sogatella furcifera (Hemiptera: Delphacidae), although itcan also be transmitted by the small brown planthopper(Laodelphax striatellus Fallen). Since 2010, severerepeated outbreaks of SRBSDV have been reported in Liboand Tianzhu County of Guizhou Province. The disease hascaused severe crop damage in around 5 000 ha annually,leading to unprecedented income loss for farmers. If thevirus is not managed, it is likely to spread to otherrice-growing areas in the southern, south-eastern andsouth-west mountainous areas of Guizhou. Local farmers’use of non-target chemical pesticides to manageoutbreaks increases the resistance of rice planthoppersto the pesticides, leading to frequent outbreaks of thedisease and forcing many farmers to abandon ricecultivation. The long-term effective management ofSRBSDV disease and its vector, the rice planthopper, inLibo and Tianzhu is thus a top priority, not only to protectthe livelihoods of poor ethnic minority farmers but alsoto safeguard ecology and biodiversity in the area. -
ProjectImproving Fertilizer Utilization and Agricultural Ecological Environment in Xinjiang - TCP/CPR/3607 2020
Also available in:
No results found.Xinjiang Uygur Autonomous Region of China has exceptionally good conditions for developing organic farming, with rich resources of water, land and photothermal resources, and a unique climate. However, until now, fertilizers have been the driving force promoting the increase of agricultural products in Xinjiang. The misuse of agrochemicals over the past three decades (e.g. excessive application of fertilizers, unbalanced use of organic and mineral compounds, uncoupling of water and fertilizers) has given rise to a decreasing margin of yield growth, as well as an increased outbreak of pests and diseases, polluted and degraded water and soil; and an excessive burden on the local agricultural ecological system. Against this background, the implementation of a long-term effective fertilizer utilization technology and strategy in Changji City, Balikun County and Gongliu County in Xinjiang was a top priority issue, in order to protect the livelihoods of poor ethnic minority farmer groups, and to safeguard agricultural ecology and biodiversity in this area. The project introduced a set of improved fertilizer utilization technologies and practices, aimed at better fertilizer use structure and efficiency, and a more sustainable agricultural ecological environment, combined with interventions to increase agricultural producers’ awareness and capacity. -
ProjectGreen Agriculture Development in Hainan Based on the Livestock-Biogas-Crop Circular Model - TCP/CPR/3703 2022
Also available in:
No results found.The rapid development of a large scale and intensive farming industry in Hainan has led to a sharp increase in livestock and poultry manure, which poses a significant challenge to both the ecological environment and human health The treatment and disposal of livestock manure have become a bottleneck that limits the development of the breeding industry in a green and sustainable way In recent years, China has attached great importance to the development of ecological circular agriculture Biogas treatment has arisen as an important way to manage livestock manure By utilizing manure to produce biogas and then promoting the use of biogas, rural areas can greatly reduce the use of fuel and coal Rural sanitation and living environment can be improved, and soil health and plant growth can also benefit from the provision of biogas slurry nutrient If well managed, the biogas can provide an effective and efficient alternative in support of green and ecological agriculture development Hainan Province is a tropical island in China Tropical cash crops, and livestock and poultry farming are the major income sources for Hainan farmers Located in the north of Yazhou District, Sanya City, Hainan Province, Beiling Village is home to 3 857 famers, including 3 852 from the Li ethnic minority, accounting for 99 9 percent of the total Local villagers rely on mango and banana as the main cash crops.
