上思香糯提纯复壮及推广应用项目品种筛选试验

Experiment on Variety Selection for Purification Revitalization and Promotion of Shangsi Xiangnuo Glutinous Rice

摘要: 从上思县8个乡镇（村）取样香糯水稻品种8个，在同一大田内，相同的种植密度、栽培管理条件下，进行株高、分蘖力、抗倒伏能力、品质及产量对比提纯复壮筛选试验。结果显示，综合表现较好、产量较高的是华兰、六甘、南屏、在妙这4乡镇所取样的品种，平均产量分别达408.4 kg/666.7 m²、394.2 kg/666.7 m²、391.1 kg/666.7 m²、385.4 kg/666.7 m²，均比农业部门农情统计的上思香糯平均单产300.2 kg/667 m²更高。

Abstract: Eight Xiangnuo varieties were sampled from 8 towns （villages） in Shangsi County.In the same field,under the same plant‐ing density and cultivation management conditions,the plant height,tillering ability,lodging resistance,quality and yield were com‐pared and the screening tests were carried out.The results showed that the varieties sampled from Hualan,Liugan,Nanping and Zaimiao had better overall performance and higher yield,with average yield reaching 408.4 kg/666.7 m~2,394.2 kg/666.7 m~2,391.1kg/666.7 m~2and 385.4 kg/666.7 m~2,respectively.The average yield of Shangsi Xiangnuo was 300.2kg/667 m~2higher than that of Shangsi Xiangnuo in agricultural statistics.
