| 摘 要： | 为了提高平凉山药的繁殖效率,研究了塑料大棚条件下山药珠芽不同栽培密度对当年形成的种薯的茎鲜质量、珠芽质量、种薯横径、单薯质量、产量等指标的影响.研究结果表明,大棚栽培珠芽较露地栽培能提早出苗12 d;珠芽栽培密度对山药种薯生育期无明显影响;珠芽栽培密度越大,种薯的单质量下降越明显(f=0.631**);合理的栽培密度为...

| Abstract: | In order to improve the reproduction efficiency of the Pingliang Chinese yam,studied the effects of different cultivation density of yam bulbils on stem fresh weight,yam bulbils weight,seed tuber transverse diameter,single weight of yam seed tuber and yield,all which produced at the same year under the plastic shed condition.The findings indicated the emergency time under plastic shed condition was earlier 12 days than that under the ground.Cultivation density of bulbils had no significant efficiency on yam... |
