红果参栽培技术研究

Study on Cultivation Technology of Campnumoea lancifolia(Roxb.)Merr.

选用海拔1 800~2 600 m驯化繁殖1年以上的红果参优质组培苗,探讨海拔、覆膜、遮阴和肥料对红果参产量和产量构成因素的影响。结果表明,红果参最适宜海拔为2 450 m;覆黑色地膜的种植方式可促进红果参生长发育进程;在种植初期用75%遮阳网遮阴可使红果参的成活率达95%以上;种植密度采用80 cm 100 cm,施用30 000 kg/hm^2腐熟农家肥和1 500 kg/hm^2复合肥;采用追肥、底肥各施1/2;11月采收的处理方式产量为4 825.20 kg/hm^2,与其他处理方式的产量差异极显著(P<0.01)。

High quality tissue culture seedlings of Campnumoea lancifolia(Roxb.)Merr.,which were breeding for more than one year at the altitude of 1800-2600 m were selected as study materials.the effect of altitude,mulching,shade and fertilizer on the yield and quality of Campnumoea lancifolia(Roxb.)Merr.were studied.The results showed that the most suitable planting altitude was 2450 m;the planting pattern of black mulch could promote the growth and development of Campnumoea lancifolia(Roxb.)Merr.;the survival rate could reach more than 95%by shading with 75%shading net at the beginning of planting.Under the condition of 80 cm 100 cm of planting density,45000 kg/hm^2 of humic farm manure and 1500 kg/hm^2 of compound fertilizer,1/2 of topdressing and 1/2 of base fertilizer,the harvested yield was 4825.2 kg/hm^2 in November,and the output was significantly higher than that of other treatments.
