| 摘 要： | 在郁闭杨树林地间作麦冬,研究不同施肥处理对麦冬生长的影响。结果表明:施肥对2年生麦冬的地上部分鲜重及分蘖株数的影响不大,但对麦冬块根生长有极显著促进作用。3种施肥处理对比不施肥的对照,块根鲜重分别增加了179%、196%、342%,块根干重分别增加了170%、177%、294%。在复合肥用量不变的情况下,增加鸡粪用量到15 000 kg/hm~2,麦冬块根鲜、干重分别为2 861 kg/hm~2、1 408 kg/hm~2,相比鸡粪用量3 750 kg/hm~2处理,块根鲜、干重分别增加了58.8%、46.1%;相比鸡粪用量7 500 kg/hm~2处理,块根鲜、干重分别增加了49.2%、42.5%。施肥还有助于提高麦冬块根的外观品质。

| Abstract: | Intercropping Ophiopogon japonicus in the woodland of the poplar closed forest,the effect of different fertiliza-tion treatments on the growth of Ophiopogon japonicus was studied. The results showed that,fertilization had little effect on the fresh weight of shoot and tiller number for the 2 years old Ophiopogon japonicus,but fertilization had a very signifi-cant effect on the growth of the tuberous root. Under three fertilization treatments compared with no fertilizer treatment, the fresh weights of the tuberous roots increased by 179%,196%,342% and the dry weights of the tuberous roots in-creased by 170%,177%and 294%. In case of constant compound fertilizer dosage,increasing the chicken manure dos-age to 15 000 kg/hm2,the fresh and dry weight of tuberous roots were 2 861 kg/hm2 and 1 408 kg /hm2,compared with the treatment of chicken manure dosage of 3 750 kg/hm2 ,the fresh and dry weights of tuberous roots increased by 58.8%and 46.1%,and compared with the treatment of chicken manure dosage of 7 500 kg/hm2 ,the fresh and dry weights of tuberous roots increased by 49.2% and 42.5%.Not only that,the fertilization also improved the appearance quality of the tuberous roots of Ophiopogon japonicus. |
