本文研究了不同类型小麦品种在不同密度和施肥水平下的生育和代谢特性。结果表明,品种间产量差异显著,对研究的两种栽培方法有不同的反应。稀播高肥处理,所有品种植株矮壮,体内含氮量、分蘖成穗率高,剑叶的光合势大,每穗粒数多,单株生产力高。高产品种生育后期干物质积累多,稀播下成熟期间的物质积累增多。
This article studied the fertility and metabolic characteristics of different types of wheat at different densities and fertilization levels. The results showed that there was significant difference in the yield among the cultivars and different responses to the two cultivation methods studied. Thin and sowing high fertilizer treatment, all varieties of plant short stature, nitrogen content in the body, the rate of tillering into a high, the flag leaf photosynthetic potential, grain number per spike, single plant high productivity. High-yielding varieties have more dry matter accumulation in later growth period and more material accumulation in mature period under thinning.
