摘  要：
为缓解太子参的连作障害,实现太子参的高产优质栽培,采用4因素3水平正交试验研究了不同处理对太子参单个块茎茎长、茎粗、鲜重、产量、多糖含量的影响,并对多糖含量进行极差分析。结果表明,太子参连作障害防控技术的最优组合为栽植深度11 cm,土壤消毒液为福尔马林,基肥施用量为每公顷施草木灰1 500 kg、磷肥450 kg、复合肥225 kg、硫酸钾225 kg,病害药物防治措施为喷50%多菌灵1 000倍稀释液。

摘  要：
In order to furthest relieve the continuous cropping obstacles of Pseudostellaria heterophylla,to realize its high yield and quality cultivation,the four factors and three levels orthogonal test L9(34) was performed.Effects of stem length,stem diameter,fresh weight,moist yield and polysaccharide content of single tuber of P.heterophylla under different treatments were studied,and range analysis on polysaccharide content of yield was made,the optimal combination of main prevention and control techniqes of continuous cropping obstacles of P.heterophylla were obtained.That is,the transplant depths was 11 cm,soil disinfection solution was formalin,amounts of base fertilizer were plant ash was 1 500 kg/hm2,phosphorus was 450 kg/hm2,compound fertilizer was 225 kg/hm2,potassium sulfate was 225 kg/hm2,and drug prevention measure of diseases was 1 000 times liquid of 50% carbendazim.
