摘要
为了解不同种植密度对葛根产量及品质的影响,进一步筛选出适宜的种植密度,以细叶葛根扦插苗为试验材料,采用不同种植密度(16500、13500、12000、10500、9000株/hm^2)单行种植,研究不同种植密度对葛根产量及品质的影响,旨在为提高广西葛根栽培水平及规模化、标准化栽培提供理论依据。结果表明,当种植密度为12000株/hm^2时,葛根单株产量、折合小区产量、茎粗、淀粉、总糖、可溶性蛋白均达到最大值,分别为4.12 kg、161.2 kg、11.93 mm、290.0 g/kg、9.5 g/kg、25.2 g/kg,与其他处理存在显著差异;且在主成分分析中,12000株/hm^2处理得分最高。因此,在该试验条件下,广西葛根最适宜种植密度为12000株/hm^2。
The purpose of the study was to understand the effects of different planting densities on the yield and quality of Pueraria,which was to screen out the suitable planting densities further,and to provide theoretical basis for improving the cultivation level of Puerari in Guangxi and for large-scale and standardized cultivation.The study on effects of different planting densities on yield and quality of Pueraria was tested with fine leaf Pueraria as experimental materials and adopted with various densities(16500,13500,12000,10500,9000 plants/hm^2).The results showed the yield of single plant,plot yield,stem diameter,starch,total sugar and soluble protein reached under 12000 plants/hm^2,which were respectively 4.12 kg,161.2 kg,11.93 mm,290.0 g/kg,9.5 g/kg,25.2 g/kg,and was significant differences with other treatments.In principal component analysis,the treatment of 12000 plants/hm^2 got the highest score.Therefore the optimum planting density of Pueraria in Guangxi was 12000 plants/hm^2 under the experimental conditions.
