[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100 cm、垅高20 cm、垅面宽60~65 cm的基础上,试验设6个种植密度处理:种植密度42 000株/hm2,株距47.62 cm;种植密度47 250株/hm2,株距42.33 cm;种植密度52 500株/hm2,株距38.10 cm(CK);种植密度57 750株/hm2,株距34.63 cm;种植密度63 000株/hm2,株距31.75cm;种植密度68 250株/hm2,株距29.30 cm。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]63 000株/hm2种植密度处理子孙芋产量最高,达25 103.70 kg/hm2,商品芋效益为97 738.2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63 000株/hm2为宜。
[Objective] The research aimed to discuss the effects of different planting densities in high sandy soil area on the growth, yield and benefit of Taixing fragrant taro with moderate fertility. [Method] Based on the unified width of 100 cm, height of 20 cm and width of 60 cm to 65 cm, six planting density treatments were planted: the planting density of 42 000 plants / hm2, the plant spacing of 47.62 cm and the planting density of 47 250 Plant height of 42.33 cm; plant density of 52 500 plants / hm2, plant spacing of 38.10 cm (CK); planting density of 57 750 plants / hm2, plant spacing of 34.63 cm; planting density of 63 000 plants / hm2, plant spacing of 31.75 cm; 250 plants / hm2, plant spacing 29.30 cm. Examine the growth and development of seedlings at different growth stages, offspring taro yield, commodity taro benefits. [Result] The seed yield of 63 000 plants / hm2 planting density was the highest, reaching 25 103.70 kg / hm2, and the yield of commodity taro was 97 738.2 yuan / hm2. [Conclusion] Under medium fertility condition, the planting density of Taixing fragrant taro in high sandy soil area was 63 000 plants / hm2.
