甜菜移栽露地采种与直播露地越冬相比,用种少(每亩0.1公斤)、产籽多(我场两年种3,000余亩,平均单产175公斤,高产田350公斤以上)、繁殖系数高、种球大、色泽好、发芽率高、种子质量好,深受北方用种单位的欢迎。采种甜菜要获得高产、冬前营养生长期,要求母根直径在3厘米以上(在安全越冬的前提下,产籽量与越冬母根的大小呈正相关)。而冬前母根的大小在相同播期及栽培管 Sugar beet transplanting open-field planting and direct-field open-air compared to winter, with less species (0.1 kg per acre), more seeds (more than 3,000 acres in my field for two years, an average yield of 175 kg, 350 kg high yield), high coefficient of multiplication , Bulbs big, good color, high germination rate, good seed quality, welcomed by the northern species units. To grow beet in order to get high yield, before winter vegetative growth period, the diameter of parent root is required to be more than 3 centimeters (under the condition of safe wintering, seed yield is positively correlated with the size of overwintering parent). The size of winter before the mother’s sowing and planting tube
