| 摘 要： | 为了评估哈尼水稻地方品种可持续发展的内在因素,调查了元阳县水稻地方品种的多样性和箐口村水稻种子的更换情况,结果显示元阳水稻地方品种多样性的减少比发达地区缓慢的多.在婚姻状况和海拔梯度两方面,哈尼的换种表现出明显的规律性.68.6%的非本村互婚户从外村引种,55.1%的本村互婚户在村内互换种子,购买种子的农户极少;35%...

| Abstract: | To evaluate the intrinsic factors of Hani rice landrace sustainable development,the rice landrace diversity in Yuanyang County and seed exchange in Qingkou village was surveyed.The results showed that the diversity of rice landraces in Yuanyang County was reduced slower than that in modern culture region.In terms of altitude gradient and marital status,the seed exchange among Hani people has a clear rules;68.6% exogamous households exchanged seed outside their village and 55.1% inside,the ratio of purchase ... |
