NGHIÊN CỨU ẢNH HƯỞNG CỦA THỜI VỤ TRỒNG VÀ THỜI VỤ THU HOẠCH ĐẾN NĂNG SUẤT DƯỢC LIỆU CÂY SÂM ĐẠI HÀNH (ELEUTHERINE BULBOSA (MILL.) URBAN) TẠI THANH HÓA

Abstract

Experimental design of growing season, harvesting season of Eleutherine bulhosa (Mill.) Urh., hy RCBD field experiment, 3 replications was carried out. Planting seasonal experiment consists of 6 formulas (Growing in October, November, December, January’, February, and March) and harvested time experiment consists of 3 formulas (harvesting 330 days after planting, 360 days after planting 390 days after planting). The aim o f this study was to find which planting season and harvest time are for high yield materials. The research has shown that the planting seasons having high average yield in November - December was 2.53 - 2.59 tons/ha/year, the highest of which was in November, the average yield was 2.59 tons/ha/year. The time to harvest the best medicinal plant was after 390 days, the average yield was from 2.64 tonnes/ha/year.
