摘要：基于西北山区气候特征和耕作传统特点,探索适宜西北干旱山区的高产党参栽培技术。在前期大田生产观察的基础上,考察4种代表采收和耕作特征农田在党参生长过程中土壤保墒能力、杂草生长情况、党参生长发育、党参产量和性状质量方面的差异。前茬不同收获和耕作时间对党参田土壤水分和田间杂草生长数量、党参生育期、产量和性状都具有显著差异性影响,其中轮休地土壤保墒能力最佳,杂草数量最小,党参产量最高,党参药材性状质量也最好。选择轮休田进行党参生产,能够明显的提高田地保墒能力,减少田间杂草的生长,延长党参的生长周期,从而有效地提高党参的产量和质量,保证党参的稳产、高产。
Based on climate and cultivation tradition of the northwest areas,the study aims to determine the high-yielding cultivation measures for Codonopsis pilosula.Based on the previous observation on field production,four typical Codonopsis pilosula field representing different harvesting time and farming measures,were selected to evaluate differences of soil moisture conservation,growth of weeds,as well as development,yield and appearance qualitative traits of Codonopsis pilosula.The results showed that harvesting time of previous crops and farming had significant influence on soil moisture of Codonopsis pilosulafield,number of weeds,and growth period,yield and appearance quality of Codonopsis pilosula.The land on fallow rotation was characterized as better soil moisture conservation,less weed,high yielding and the best quality of Codonopsis pilosula.So,choosing the land on fallow rotation characterized well soil moisture conservation and less weeds to produce Codonopsis pilosula can prolonge growth period and improve yield and appearance quality of Codonopsis pilosula.
