摘　　要：以华南205为研究对象,研究粉垄耕作条件下减施肥料对木薯块根产量和品质的影响。结果显示:(1)随着施肥量的减少,常耕和粉垄两种耕作方式下的木薯株高、茎粗、产量均随之下降,但粉垄耕作的下降幅度较小,当减施肥料30%时仍能保持常规耕作全施肥量相当的鲜薯产量;(2)粉垄减施肥料后对鲜薯块根中的淀粉含量、干物质无显著影响,但是可以显著降低氢氰酸含量。因此,粉垄耕作条件下,减施30%左右的肥料可以保证木薯的产量和品质。South China 205 of cassava was.taken.as the.research object,and a study was conducted to investigate the effect of fertilizer reduction on cassava root yield and quality under the Fenlong tillage.The results showed that:(1)With the fertilizer reduction,the cassava plant height,stem diameter,yield decreased under both traditional tillage and Fenlong tillage,However,the decline under Fenlong tillage was smaller,and 30% reduction of fertilizer treatment remained the similar yield with the treatment without fertilizer reduction under traditional tillage.(2)Fenlong tillage with reduction fertilizer management had no obvious effect on starch content and dry matter in fresh tuber,but significantly reduced hydrocyanic acid content.Therefore,about 30% reduction of fertilizer application can ensure the yield and quality of cassava under Fenlong tillage.
