针对贵州冬春低温的气候特点，探讨木薯在贵州的适宜播种期。结果表明：从2月底至4月底，随着播种期推迟，出苗快，出苗整齐，但株高和茎径降低，植株营养生长不够，而产量降低，试验以3月前播种为最好，最迟不超过4月上旬，过晚播种产量明显降低；播种过早，通过16℃的保证率为33.3%，种茎受低温霜冻危害的可能性大；在贵州播种期对淀粉含量没有影响；木薯在贵州的适宜播种期为3月。

This experiment aims at the climate characteristic of Guizhou winter low temperature, suitable seeding time of cassava in Guizhou is discussed, and the results showed that from late February to the end of April, as the seeding time delayed, while the fast, neat emergence, but plant height and stem diameter, plant vegetative growth, and yield is reduced, this test by seeding for the best 3 month ago, can't more than early April, the latest late sowing yield significantly reduced; Early sowing, through 16 ℃ assurance rate of 33.3%, a big stems from the possibility of frost damage at low temperature; Seeding time in Guizhou province has no effect on starch content. Suitable seeding time of cassava in Guizhou for 3 month.
