摘要
研究了不同播种方式和密度对长江中游流域丘陵旱地中高产条件下湘花生3号的农艺性状、经济性状、产量以及种植效益的影响。结果表明：湘花生3号在中高产旱地条件下播种密度以16 666-30 000株/667 m^2为宜,植株配置方式以宽行窄穴双株（30 cm×12 cm×2）的产量最高,而综合效益以（24 cm×12 cm×1）和（18 cm×18 cm×1）较好。
The present paper was conducted in hilly arid areas in middle reaches of the Yangtze to study the effect of different plant populations and their arrange pattern on pod yield, yield factors and economic benefit of seedling type peanut Xianghua 3. The results showed that appropriate higher planting density range from 16 666 plants /667 m^2 to 30 000 plants /667 m^2 was necessary to obtain higher pod yield. The plant arrange pattern which could contribute the highest yield was wide - row, narrow - hole and Two- plantlets- in- one- hole （30 cm × 12 cm× 2）, while the plant arrange pattern which could obtain the best comprehensive benefit should be setted to 24 cm × 12 cm× 1 or 18 cm ×18 cm ×1.
