目前我国甜高粱栽培以去除分蘖栽培为主,去蘖栽培需耗费大量人力,已成为甜高粱生产和大面积推广的重要限制因子之一。用7个甜高粱杂交种,对7个主要经济性状进行调查分析,研究去除分蘖和自然生长对甜高粱主要农艺性状和经济性状的影响。结果表明:去蘖处理使穗长显著变短,鲜重极显著降低。甜高粱留蘖栽培不仅可免除栽培中去除分蘖造成的人力财力浪费,同时可获得更高的产量。
At present, the cultivation of sweet sorghum in our country is dominated by the removal of tillers, and the removal of tillers is labor-intensive and has become one of the most important limiting factors in the production and promotion of sweet sorghum. Seven sweet sorghum hybrids were used to investigate and analyze the seven main economic traits. The effects of tillering and natural growth on the main agronomic and economic traits of sweet sorghum were studied. The results showed that tiller treatment significantly shortened spike length and fresh weight decreased significantly. Sweet sorghum tillering cultivation not only eliminates the waste of human and financial resources caused by the removal of tillers during cultivation, but also achieves higher yield.
