摘要
为了探索生物炭施用量对盐碱化土壤种植玉米的效果,进行了田间小区试验,研究了生物炭不同施用量(0,10,20,40和80 t·hm^(-2))对玉米生长、养分积累及产量的影响。结果表明,生物炭增加了花后干物质积累量,促进了籽粒灌浆速率,提升了玉米植株及籽粒对养分(C、N、P、K)的吸收,进而提高了玉米产量,改善了玉米品质。因此,在松嫩平原西部碱化玉米田上生物炭施用量40 t·hm^(-2)时玉米植株叶茎鞘养分积累最为充足,籽粒灌浆活跃期长,玉米产量最高,为最经济有效的用量。
In order to explore the optimal application rate of biochar for planting maize on saline alkali soil,a field plot experiment was conducted to study the effects of different application rates(0,10,20,40,80 t·ha^(-1))of biochar on maize growth,nutrient accumulation,and yield.The results showed that,biochar increased the accumulation of dry matter after flowering,promoted the increase of gra in filling rate,and enhanced the absorption of nutrients(C,N,P,K)by maize plants and grains,thereby increasing maize yield and improving maize quality.Therefore,in the alkaline maize field of the western Songnen Plain,the application amount of biochar of 40 t·ha^(-1) is the most sufficient for nutrient accumulation in the leaves,stems,and sheaths of maize plants,with a long active period of grain filling and the highest maize yield,making it the most economically effective amount.
