Abstract:

Planted cassava by smash-ridging cultivation technology, compare with traditional cultivation, ascertain difference at roots, yield, quality and so on, provide the basis for the smash-ridging cultivation. The ‘Huanan205’ and ‘Xinxuan048’ of cassava verities as materials, at maturation period, smash-ridging cultivation and traditional cultivation comparative experiment at the same location for two years, investigate or measure roots, yield, quality and so on. The results showed that, compared with traditional cultivation, smash-ridging cultivation cassava could cause per plant roots rise 23.13%-39.10%, increased length of root from 6.94% to 60.00%, increased root diameter between 8.40% and 13.91%, the yield increased 29.22%-63.78%, and improved quality of fresh cassava, the starch increased 3.23%-18.67%. This paper showed that smash-ridging cultivation can increase the yield of cassava, and improve quality. And discussions “roots as basic theory” of crop cultivation which roots for leading.
