| 摘 要： | 目的]探讨中等肥力状况的高沙土地区不同种植密度对泰兴香荷芋生育及产量、效益的影响。方法]在统一垅宽100cm、垅高20cm、垅面宽60～65cm的基础上，试验设6个种植密度处理：种植密度42000株／hm2，株距47．62cm；种植密度47250株/hm2，株距42．33cm；种植密度52500株／hm2，株距38．10cm（CK）；种植密度57750株／hm2，株距34．63cm；种植密度63000株／hm2，株距31．75cm；种植密度68250赫／hm2，株距29．30cm.考查不同生育期的苗情与长势、子孙芋产量、商品芋效益。结果]63000株／hm2种植密度处理子孙芋产量最高，达25103．70kg,／hm2，商品芋政益为97738．2元／hm2。结论]中等肥力状况下的高沙土地区泰兴香荷芋大面积种植密度以63000株／hm2为宜。

| Abstract: | Objective ] The aim was to discuss the impact of different plant densities on reproduction and output benefit of Taixing Xianghe ta- ro in high sandy areas of moderate fertility status. Method ] Based on the uniform ridge bottom width 100 em, ridge height 20 cm, ridge surface width 60 - 65 cm, six planting densities treatments were designed as follows ： planting density 42 000 plants/bin2 , rows spacing 47.62 era; planting density 47 250 plants/hm2 , rows spacing 42.33 cm; planting density 52 500 plants/hm2 , rows spacing 38.10 cm（CK） ; planting density 57750 plants/hm2 , rows spacing 34.63 cm; planting density 63 000 plants/bin2, rows spacing 31.75 cm; planting density 68 250 plants/hm2 , rows spacing 29.30 era. The seedling condition and growth vigor during different growth periods, offspring taro yield and the output value of commodity taro at malurity were investigated. Result] The planting density treatment of 63 000 plant/hm2 enabled the offspring taro to reach its highest yield by 25 103.70 kg/hm2 , and the economic benefit of commodity taro was 97 738.2 CNY/hm2. Conclusion] In high sandv areas of moderate fertility, nlantinz density of 63 000 nlant/hm2 is suitable for Taixing Xianghe taro. |
