本文从杂交红麻的纤维产量优势效应和优势性状表现的特点两方面对选育的抗病、高产杂优组合 H005(722×青皮3号)进行了论述。大量试验证明:红麻杂种优势是显著的,植株营养体的优势表现是多方面的,其中以单株纤维重和单位面积有效株数的优势最显著。在组成单株纤维重的诸因素中,按优势指数大小的顺序依次为茎粗、株高、出麻率和皮厚。据各地测产,该组合比生产上大面积栽培的青皮3号品种平均增产24.5%,每亩净增产值40～50元,经济效益显著,适应范围广。这项研究,为我国红麻生产的进一步发展开辟了一条新途径。 In this paper, the resistant and high-yielding heterosis combination H005 (722 × Qingpi No.3) of hybrid kenaf was discussed from the aspects of the fiber yield superiority and the characteristics of the dominant traits. A large number of experiments show that: kenaf heterosis is significant, the advantages of vegetative body performance is multifaceted, of which the single fiber weight and the number of effective units per unit area the most significant advantage. In the composition of fiber weight of the various factors, according to the order of the size of the dominant index of stem diameter, plant height, hair rate and skin thickness. According to the local production survey, the combination of large-scale production than the production of cultivars Qingpi No. 3 an average increase of 24.5%, net output per acre 40 to 50 yuan, significant economic benefits, to adapt to a wide range. This study has opened a new avenue for the further development of kenaf production in our country.
