春小麥籽粒高分子量麥谷蛋白亞基積累過程中不同形態氮肥的調節作用When inadequate n was added, the chloroplast structure in mesophyll cell was damaged in ear leaf, the amount of carbohydrate decreased in mestome sheath, and excessive n - redistribution and n - transportation to grain from vegetative mass appeared, which resulted in earlier leaf senescence. excessive n application led to too high activity of nitrate reductase, excessive vigorous nitrogen metabolism and too much exhaustion of carbohydrate in ear leaf, which resulted in the lack of enough carbohydrate in the lower leaf, meanwhile, the expansive chloroplast grana lamellae in leaf mesophyll cell and starch grain without nuclear in mestome sheath cell was observed, which led to the decrease of chlorophyll content and photosythetic capacity in maize leaf, then the early senescence occured
氮肥用量不足導致穗葉葉肉細胞葉綠體結構性差,維管束鞘細胞碳水化合物累積減少,營養體氮素再分配率大而引起葉片早衰;而過量供氮則導致生長後期硝酸還原酶活性過高,氮素代謝過旺,消耗了大量碳水化合物,以致下位葉不能得到充足的碳水化合物供應而提早脫落,同時葉肉細胞葉綠體片層結構膨脹,呈「肉汁化」特徵,維管束鞘細胞澱粉粒大量消耗,無核澱粉粒出現,從而葉片葉綠素含量下降,光合能力降低而出現早衰。With nitrogen ( n ) consumption in 1989 at 15. 36 million tons, it would seem obvious that large economic loses occur due to inefficient use of part of this n because china does not use one of the simplest components of myr, balanced npk fertilization
