摘　　要：对贵州省凤冈县西山黄精GAP试验示范基地栽培黄精和多花黄精开花结实情况进行观察。发现两种黄精的花均是从基部向上顺序生出和开放,蕾期45 d左右,花期20 d。结实时间10余天,结实率黄精为36.35%、多花黄精为58.37%,果实成熟期达半年以上,落果严重,田间成熟果实量非常小。分析成熟果实少的原因,认为与果期太长、落果严重、大部分植株秋季死亡、留种田肥力较低等多种因素有关。To observe the bloom and fructify the circumstance of Culture Polygonatum on the Experiment and demonstrate Xishan Polygonatum GAP base of Guizhou province Fenggang county. The flower that discovers two kinds of Culture Polygonatum all headings expects about 45 days, blossom perion about 20 ex Redoute. and P. cyrtonema Hua ＇ s ripening up the sequence to living and open from the base, the bud stage days. Seeding stage is more than 10 days, P. sibiricum Delar. rates are 36.35% and 58.37%, the fruit maturity expects to reach the half a year above, fall the fruit severity, mature fruit quantity in in the field is very small. Reason of little analytical mature fruit, think to expect with fruit too grow to fall the fruit severity, big parts of plants autumn death, stud farm lower various of fatty dint and etc. factors relevant to.
