采取管栽法对比研究了杂交小麦与普通小麦不同生育时期根系生育特点。结果表明,杂交小麦各生育时期单株次生根、单株根干物质积累、深层根量占总根干重比例等方面均比普通小麦优势明显,与之相应的地上部分单株生物产量和籽粒产量也表现了一定的优势。为杂交小麦高产稳产栽培提供了一定依据。
The tube planting method was used to study the characteristics of root growth in different growth stages of hybrid wheat and common wheat. The results showed that both the secondary roots and root dry matter accumulation in hybrid wheat at each growth stage were superior to that of common wheat in terms of the proportion of deep roots and total root dry weight. The aboveground biomass per plant and grain Production also showed some advantages. It provided a certain basis for the high and stable cultivation of hybrid wheat.
