(一) 纳容乡地处紫云西南部,位于北纬25°38′,东经106°10′。河谷槽子,西北东南走向。有典型的南亚热带气候特点。水热资源较为充裕。年均温17.1℃。年降水量1300—1400mm,海拔高度800—840米。该乡为紫云县水稻产区之一。 纳容乡泡冬,炕冬田面积大,常年不种小季,只种一季中稻,对水热资源利用不充分。发展再生稻能在确保一季早中稻高产的基础上,增加稻谷产量,是纳容乡增产粮食的有效途径之一。为此,紫云县农业局从1988年即开始进行本试验示范。 (二) 根据省农推总站的安排,1988年紫云县农业局
(1) Nathan Township is located in the southwest of Ziyun at latitude 25 ° 38 ’north and longitude 106 ° 10’. Valley trough, northwest southeast direction. A typical southern subtropical climate characteristics. Hydrothermal resources are more abundant. The average annual temperature of 17.1 ℃. Annual precipitation 1300-1400mm, altitude 800-840 meters. The township is one of the Ziyun rice producing areas. Nathan township bubble winter, kang winter field area, perennial non-small season, only a quarter of rice, the use of water and heat resources are not sufficient. The development of ratooning rice can increase the yield of rice on the basis of ensuring the high yield of early-season middle-season rice in one season, which is one of the effective ways to increase grain yield of NAR. To this end, Ziyun County Agricultural Bureau from 1988 that began the pilot demonstration. (B) According to the provincial agricultural push terminus arrangements, 1988 Ziyun County Bureau of Agriculture
