摘要
通过对栗园间作关玉竹技术的研究,结果表明,当年分枝的关玉竹根茎,当茎粗≥0.5cm时,其发芽率最高,达96.7%;穴栽株行距以30cm×30cm、40cm×30cm、40cm×40cm为宜,其产量在40 950～45 900kg.hm-2,条栽株行距以10cm×15cm、10cm×25cm为宜,产量达37 950～40 950kg.hm-2;变温处理种子可实现苗齐苗壮;栽后3年收获根茎商品质量最佳,4年收获量高,但品质下降。
Alternation of Castanea mollissima ＆ Polygonatum odoratum were studied. Result shows that..germina- tion rate of stem for Polygonatum odoratum in the first year are the highest,being 96.7 while the stem diameter≥ 0.5 cm;the appropriate space in row are 30 cm×30 cm,40 cm×30 cm,40 cm×40 cm while sowing in hole,its yield being 40 950-45 900 kg ·hm^-2 ;the appropriate space in row are 10 cm× 15 cm, 10 cm×25 cm,its yield being 37 950-40 950 kg ·hm^-2 ;after the seeds were treated with variable temperatures,the seedlifigs could sprout strong and good;three years after planting,quality of stem for Polygonatum odoratum are good,it obtains high yield four years after planting,but it decline in quality.
