1.品种选择 作加工用的蕌头一般选择分蘖力强的单心蕌。种植品种一般以单心蜂窝蕌为好,其鳞片多(12片左右),鳞芽出现较迟(6月中旬开始出现),分蘖能力强(可分生20个～30个)。 2.播种 ①整地作畦。蕌头的根系一般分布在15厘米～30厘米表土内,根系的吸肥、吸水能力弱。应选有机质含量多而保水能力强的旱地适当深耕, 1. Selection of varieties for the processing of the first choice of tillering strength of the single heart 蕌. Cultivars generally monoculture honeycomb as well, the scales (12 or so), late emergence of scale buds (beginning in mid-June), strong tillering ability (can be derived from 20 to 30). 2. Seeding ① soil preparation for 畦. The root of the head is generally distributed in the 15 cm to 30 cm topsoil, root absorption of fat, water absorption capacity is weak. Should be selected organic matter content and water retention ability of dry land appropriate deep plowing,
