采用“高肥宽行稀播”高产优质低耗栽培技术,小麦生育后期群体发展合理,中、下部光照充足,叶绿素含量提高,光合速率和灌浆速率加快,具有良好的光合特性。在维特较小的叶面积系数的基础上,改善光合性能,提高光合能力,是进一步提高小麦产量的一个关键。 The high-yield, high-quality, low-loss cultivation techniques of “high-yielding and wide-width thinning” high yield and good low-loss cultivation techniques demonstrated that the population of wheat developed at a reasonable rate in the later growth stages. Sufficient light was obtained in the middle and lower parts of the wheat and chlorophyll content was increased. Photosynthetic rate and filling rate were accelerated. Based on the smaller leaf area coefficient of Witte, improving photosynthetic performance and increasing photosynthetic capacity are the keys to further increase wheat yield.
