摘要
经过2年的木薯品种适应性比较研究,新选048表现出极高的鲜薯产量,达51.79t/hm2,较对照增幅57.95%,但其淀粉含量最低,仅28.5%,比对照减幅19.03%,由于其产量优势,淀粉产量达14.76t/hm2,较对照增幅27.90%;惠丰60性状较好,鲜薯产量达37.74t/hm2,较对照增幅15.1%,淀粉含量38.6%,淀粉产量达14.57t/hm2,较对照增幅26.26%。新选048和惠丰60均属高位分枝,且分枝角度小,种植可适当密植,能迎合崇左薯农的密植栽培习惯,适合在当地推广种植。华南8号属矮分枝,且分枝角度大,种植时不可过密,其鲜薯产量为37.44t/hm2,较对照增幅14.17%,但淀粉含量略低于对照,为35.1%,降幅0.28%,其淀粉产量达13.14t/hm2,较对照增幅13.87%,也适合在当地推广;GR891为高淀粉品种,植后8个月可收获,是目前淀粉含量最高和最早熟品种之一,其鲜薯产量与对照相当,但其淀粉含量和淀粉产量均高于对照,亦适合在当地推广。
After two years of adaptivity research on cassava varieties,Xinxuan 048 was found to have a high root yield,reached 51. 79 t /hm^2,with an increase of 57.95% compared with the control,but its starch content was only28. 5%,a decrease of 19. 03 % compared with the control. due to its yield advantage,starch production reached14. 76 t / hm^2,an increase of 27.90% compared with the control.Huifeng 60 had better characters：fresh potato production reached 37. 74 t /hm^2,an increase of 15.1%,starch content 38.6 % and starch production reached 14.57t/hm^2,an increase of 26. 26% compared with the control;Those two cassava varieties had high branches,small branching angle,suitable for high density planting,which was close to Chongzuo potato farmers habit. Huanan 8 had dwarf branching and branching angle,but not too dense planting. The fresh potato production was 37. 44 t /hm^2,an increase of14. 17% compared with the control,but starch content was 35. 1%,a decline 0. 28%,slightly lower than the control.It was also good for local promotion;GR891 was a high starch varieties,eight months after planting can be harvested,the amount of starch is one of the highest and most precocious species are included,its fresh potato production was similar to control,but its starch content and starch yield were higher than the control,also suitable for the local promotion.
