摘　　要：2002-2003年，在广西玉林、桂林、贺州3市8个县大面积示范推广培两优1025、中优桂99、中优838等杂交优质稻和田东香、七桂占、香占等常规优质稻组合，通过实施种子工程、开发优质稻产业、优化品种结构等措施，应用水稻免耕抛秧和旱育抛秧技术、水稻壮秧剂简化栽培技术、节水科学灌溉技术、配方施肥技术等保优增效高产栽培技术，提高了这些地区水稻的品质和产量。两年累计示范推广优质稻新品种（组合）36．2087万hm2，优质稻新品种平均每公顷比老品种增产150kg；累计新增稻谷5000万kg，新增产值5000万元，解决了水稻生产效益、农田水资源浪费和生态环保等问题，取得了较大的经济、社会和生态效益。In 2002 - 2003, hybrid high-quality rice varieties （ combinations）, such as Peiliangyou 1025, Zhongyougui 99, and Zhongyou 838 etc. ,and conventional high-quality rice varieties （ combinations ）, such as Tiandongxiang, Qiguizhan, and Xiangzhan etc. , were demonstrated and extended in a large area in eight counties of Yulin City ,Guilin City,and Hezhou City of Guangxi. Through carrying out seed project ,developing the industry of high-quality rice, and optimizing the variety structure, applying seedling-broadcast with no-tillage and seedling-broadcast with dry-breeding technology for rice, simplified cultivation technology with rice strong-seedling agent, saving-water scientific irrigation technology ,and formula fertilization technology,and so on,the quality and yield of high-quality rice were increased. The demonstration and extension area of new high-quality rice varieties （combinations） was 362.087 thousand hectare in two years,and the average increased yield per hectare of that was 150 kg as compared with old rice varieties. The increased yield of new rice varieties （combinations） in two years was 50 million kg,and the increased output value was 50 million RMB. Therefore, applying the integrated cultivation technology could solve the problems such as the production benefit of rice,waste of water resources in field and ecological environment protection,and get large economic,society and ecological benefits.
