摘要
探讨了适宜于延边地区紫苏的高产栽培技术.研究结果表明,延边地区最适宜紫苏出苗的土壤相对含水量为50%～80%,适宜播种期为4月20日～5月15日.高产密度为行距60cm,株距22cm,氮、磷、钾肥施用量分别为120kg/hm2、80kg/hm2和60kg/hm2.紫苏每株荚数和分枝数对紫苏的高产起主要作用.
The high-yield cultivation technique of Perilla frutescens (Linn.) Britt. in Yanbian area was researched. The results indicated that the fit relative water quantity of soil for the (emergance) of Perilla frutescens (Linn.) Britt. was 50%～80%; the fit seeding period was from April 20th to May 15th. Its high-yield cultivation density was linewidth 60 cm and row spacing 22 cm. Its high-yield fertilizer amount was N:120 kg/hm^2, P:80 kg/hm^2, K:60 kg/hm^2. The legumen amount of individual plant and divarication amount were major effects on its high-yield.
