摘要
研究了几种栽培措施对小麦籽粒蛋白质含量的影响。降低种植密度,增加生育后期的氮肥用量,以及喷施某些植物生长调节剂(PGR),可以不同程度地提高小麦籽粒的蛋白质含量。播种期的影响很大,春播条件下籽粒蛋白质含量很高,但千粒重明显降低,适当调整播期,可望提高蛋白质含量。本文就栽培措施影响蛋白质的生理机制进行了讨论。
The effect of some eultivation measures on protein content of wheat grains was studiedin this papor.Redueing of plant density,increasing of N Fertilizer application rate in lategrowth stage and spray-ing of some plant growth regulators (PGRs) can increase proteincontento of wheat grains in different extent.There was great effect of sowing dates inprotein content,which was very high for seeding in spring.Increasing of protein contentmay be expected by appropriate change of sowing dates.In the study,physiologicalmechanism of effect of cultivation measures on protein content was discussed.
