摘要
以江西地方山药品种竹篙薯为试验材料,比较了不同半套管尺寸、地上搭架方式以及栽培密度对竹篙薯商品性和产量的影响,以期为江西丘陵地区提供优化的半套管栽培模式。结果表明,在套管长度相同情况下,管子直径大的,块茎的长度明显缩短,而长度1.0m套管下块茎长度明显优于0.8m的,但是1.0和1.2m套管下块茎长度相差不大,综合分析产量和成本,100*6.0*3.5cm的套管适合于竹篙薯栽培;相对于传统人字架,网架栽培能显著改善山药通风透光性,对于提高光合作用,减缓病害发生具有重要作用,因此,网架栽培的产量和质量也显著高于人字架栽培;虽然竹篙薯产量随种植密度增大而增大,但是结合商品性,密度为140*30cm达到最佳。
Taking dioscorea opposite ‘zhugaoshu',a local rhizoma dioscoreae variety of Jiangxi province,as the experiential materials,this paper investigated the influence of pipe size,frame pattern and planting density on commodity or output,aiming to provide an optimized half-pipe cultivation technique for ‘zhugaoshu'in the hilly area of Jiangxi province.The results showed that for the samples with the same length of pipe,the length of tuber is positive correlated with the length of pipe,but the length difference between tubers with 1.2 mpipe and tubers with 1.0 mpipe is not significant.Thus,based on comprehensive analysis of output and cost,100*6.0*3.5 was the suitable size for pipe cultivation.Compared with the traditional A-frame cultivation,the grid cultivation can significantly improve the ventilation,transparency and photosynthesis,while slow down the occurrence of disease.Therefore,the yield and quality of tuber in grid cultivation were significantly higher than those of cultivated A-bracket cultivation.Although the yield raised with the increase of planting density,the optimal density was 140*30 cm due to the commercial demand.
