几种主要有机复合(混)肥对太子参产量的影响

目的]研究几种主要有机复合(混)肥对太子参产量的影响。方法]以化学复混肥为对照,研究药渣菌肥、草炭菌肥、食品加工尾渣肥料、草炭菌肥+化学复混肥对太子参产量的影响。结果]不同肥料处理对太子参各处理间株高均有影响,变幅在0.3～1.8 cm;不同肥料处理对太子参单条块根个体影响不大,各处理间块根的平均长度变幅在0.47～1.24 cm,粗度变幅在0.27～0.41 cm,块根平均长度最大差异不足1.3 cm;草炭菌肥、施药渣菌肥、食品加工尾渣肥料和草炭菌肥+化学复混肥后的产量比对照(施用化学复混肥)高,产量以T1最高;T1、T2处理的pH值较基础土样略有降低外,其他处理的pH值均有所提高。结论]在施秉县及其类似生态环境下,施用草炭菌肥对太子参的产量较其他品牌的肥料有一定程度的增产增效作用。

Effects of Several Major Organic Compound (Mixed) Fertilizer on the Yield of Pseudostellaria heterophylla (Miq.)

Objective ] To study effects of several main organic compound （ mixed ） fertilizer on the yield of Pseudostellaria heterophylla. Method ] With chemical compound mixed fertilizer as control, effects of liquid bacteria fertilizer, peat moss bacteria fertilizer, food processing tail slag fertilizer, peat moss bacteria fertilizer ＋ chemical compound fertilizer on yield of P. heterophylla were studied. Result] Different fer- tilizers all have effects on plant height of P. heterophylla with the range of 0.3 - 1.8 cm ; different tertilizers has＂ no significant effects on single earthnut with the variation range of 0.47 - 1.24 cm, width varied between 0.27 - 0.41 cm, the biggest difference of average length is no more than 1.3 cm; the yield by treatments of peat moss bacteria fertilizer, liquid bacteria fertilizer, food processing tail slag fertilizer, peat moss bacteria fertilizer ＋ chemical compound fertilizer is higher than in control group, T1 is the highest ; pH value all improved except for T1, T2 treatment. Conclusion] In Shibing County and similar eco-environment, peat moss bacteria fertilizer can increase the yield compared with other brands.
