我们和贵州省都匀县墨冲公社河西大队第二生产队合作,进行麦烟稻三熟的试验研究。这个生产队属于山区生产队。海拔840公尺,年平均气温15.5℃。土质为粘质壤土或沙质壤土。耕地272亩,其中水田232亩,旱地40亩。以往用旱地种植烤烟,因旱地面积小,轮作困难,容易发生病害,影响了烤烟生产的发展。1976年开始试验麦烟稻三熟,小麦行里套栽烤烟,烤烟收后栽插水稻。试验结果如表1所示。
We and Duyun County, Guizhou Province Mexican commune Hexi Brigade second team to carry out experimental research on wheat and tobacco three crops. This production team belongs to the mountain production team. 840 meters above sea level, the annual average temperature of 15.5 ℃. Soil is clay loam or sandy loam. 272 acres of arable land, of which 232 acres of paddy fields, dry land 40 acres. In the past, flue-cured tobacco was planted in dry land. Because of the small area of dry land and the difficulties of rotation, diseases easily occurred and the development of flue-cured tobacco production was affected. Three trials began in 1976, wheat, wheat, tobacco lines planted tobacco, tobacco harvest after planting rice. The test results are shown in Table 1.
