摘要
为探索木薯的抗逆增产技术,设置5个生根粉浸种浓度(0、10.0、20.0、40.0、60.0 mg·L-1)、2个浸种时间(6、12 h)、以不浸种处理为对照(CK),研究其对木薯农艺性状、薯块产量与品质的影响.结果表明:与不浸种比较,20.0、60.0 mg·L-1浸种6 h和20.0～60.0 mg·L-1浸种12 h显著增粗茎径,20.0 mg·L-1浸种6 h显著提高薯长和薯径,0、10.0、60.0 mg·L-1浸种12 h显著增长薯长,0、40.0、60.0 mg·L-1浸种6 h及40.0、60.0 mg·L-1浸种12 h显著增粗薯径,20.0 mg·L-1浸种6 h鲜薯产量显著增加42.3％、淀粉产量显著提高49.9％、收获指数显著提高10.5％.综上,推荐20.0 mg·L-1生根粉溶液浸泡木薯种茎6 h的增产技术.
Abstract
In order to optimize the technology of increasing stress resistance and yield of cassava,five concentrations of rooting powder solution (0,10.0,20.0,40.0,60.0 mg·L-1) for soaking seeds and two soaking time (6,12 h) were set up by taking the non-soaking treatment as the control group (CK).Then,their effects on the agronomic traits,storage root yield and quality of cassava were studied.The results showed that:compared with no seed soaking,after soaking in the rooting powder solution with the concentration of 20.0,60.0 mg·L-1 for 6 h and soaking in the solution with the concentration of 20.0-60.0 mg·L-1 for 12 h,the stem diameter of cassava was significantly increased.After soaking in the rooting powder solution with the concentration of 20.0 mg·L-1 for 6 h,the length and diameter of storage root was significantly increased.After soaking in the rooting powder solution with the concentration of 0,10.0,60.0 mg·L-1 for 12 h,the length of storage root was significantly increased.After soaking in the rooting powder solution with the concentration of 0,40.0,60.0 mg·L-1 for 6 h and soaking in the solution with the concentration of 40.0,60.0 mg·L-1 for 12 h,the diameter of storage root was significantly increased.After soaking in the rooting powder solution with the concentration of 20.0 mg·L-1 for 6 h,the fresh storage root yield was significantly increased by 42.3％,the starch yield was significantly increased by 49.9％,and the harvest index was significantly increased by 10.5％.In conclusion,soaking the seed stem of cassava with 20.0 mg·L-1 rooting powder solution for 6 h was recommended as the yield-increasing technology.
