Abstract
In March 2020, oil tea base was established in Qingyuan, Zhejiang province with 1-year Camellia oleifera ‘Changlin 53, 4, 27’ with density of 1 333 plant/ha. In April 2020, interplanting of Chenopodium quinoa ‘Longli 1’ was implemented in oil tea plantation with 9 densities and in August 2020, investigations were carried out on agronomic traits, lodging rate and seed yield. The results showed that the treatment with spacing of 20 cm×20 cm had the advantages of higher first effective branch, less number of productive ear, as well as improved plant height, main panicle length, survival rate, lodging resistance performance and the highest seed yield among the 9 treatments. Density with 160 000-250 000 plant/ha was recommended for interplanting of Chquinoa ‘Longli 1’ in Qingyuan.
