摘要
为了探明免耕直播对高粱生物学性状、叶绿素含量和产量的影响,以吉杂123、龙杂11号和泸糯8号3个品种为材料,开展免耕直播和旋耕播种两种耕种方式的田间比较试验。结果表明,不同耕种方式除对植株干重的影响显著外,对株高、茎粗、穗长、鲜重、叶绿素含量、产量和产量构成因素均无显著影响。综合分析,免耕直播可以作为代替传统旋耕播种的一种简化高粱栽培措施推广应用。
A field comparison experiment with three cultivars,Jiza 123, Longza 11 and Lunuo 8,was conducted under the conditions of no-tillage direct seeding and conventional tillage to explore their effects on biological character, chlorophyll content and grain yield of sorghum. The results showed that there were no significant differences on plant height, stem diameter, ear length, fresh weight, chlorophyll content, yield and yield components between no-tillage and conventional tillage except dry weight. In conclusion, no-tillage direct seeding as a simplified cultivation mode for sorghum production could be popularized and applied instead of conventional tillage.
