于 1 991~ 1 994年应用盆栽和大田试验研究了前期控水节水高产技术对冬小麦根系和群体光合作用的调控作用。研究表明 ,前期限制供水有利前期根系发育 ,有利产量形成阶段光合物质生产 ,从而达到节水高产。
The pot experiment and field experiment from1991to1994was conducted to study the regulation of photosynthesis on root and population of winter wheat by pre-stage water-saving and high-yielding techniques. Research shows that the pre-restricted water supply is favorable for early root development and favorable photosynthetic production in the stage of yield formation, thus achieving high water-saving and high-yield.
