[Method] With SC9(Southern China 9) as test materials, the test included four treatment methods, as follows: control group by traditional cultivation with crops uncovered(CK), treatment 1 by traditional cultivation with mulch coverage, treatment 2 by powder ridge cultivation with crops uncovered, and treatment 3 by powder ridge cultivation with mulch coverage. Water and fertilizer managements were kept the same. [Result] Compared with traditional cultivation(CK), the treatment by powder ridge cultivation with mulch coverage performed better. Specifically, yield per unit area reached 44 790 kg/hm2, increasing by 86.38%(20 760 kg/hm2) than that of control; starch content grew by 17.24%. The cultivation method considerably improved cassava yield and quality. [Conclusion] Powder ridge cultivation with mulch coverage is a cultivation approach suitable for cassava in Hunan province.展开更多

The results showed that the highest yield of fresh root occurred with row spacing of 90 cm, and the lowest yield of fresh root was with row spacing of 75 cm. With the in- crease of row spacing, the yield of fresh root gradually increased, and reached highest yield when it planted the row spacing with 90 cm. However, as the row spacing expanded, the yield of fresh root declined. In a word, it can get a good harvest when set the row spacing of 90 cm in southwest.展开更多
