摘要:
通过对合玉21玉米株高、叶绿素、地上部生物量及品质的测定分析，研究了控释尿素对玉米生理特性和品质的影响。结果表明：控释尿素对提高玉米株高影响最大。拔节期到灌浆期，控释尿素处理叶绿素值与不施肥处理相比差异达到显著水平。灌浆期到成熟期，控释尿素处理干物质积累与不施肥处理相比差异达到了极显著水平，与普通尿素处理相比差异达到了显著水平。控释尿素处理提高玉米籽粒蛋白质和脂肪含量，降低淀粉含量，与不施肥处理相比蛋白质和淀粉含量差异达到显著水平。
Abstract:
According to the determination analysis of Heyu 21 on plant height，chlorophyll content，aboveground biomass and the quality，the effect of controlled release urea(CRU)on physiological characteristics and quality of maize were studied.The results showed that CRU has the most importance on improving maize height.From jointing to filling stage，the difference of chlorophyll content of CRU reached significant level compared with no fertilizer treatment.From filling stage to mature stage，the difference of dry matter accumulation of CRU reached extremely significant level compared with no fertilizer treatment and significant level compared with PU.CRU could increase protein and fat content and decrease starch content，the difference of protein and starch content reached significant level compared with no fertilizer treatment.
