足穗 的英文怎麼說
中文拼音 [zúsuì]
足穗
英文
ashio-
Because the appreciate interplanting period is between wheat heading and milking stage, when wheat needs 1500 - 1800 m3 / ha water, water supply should both ensure wheat requirement and prepare suitable soil moisture for maize emergence
因為適宜套種期是小麥抽穗灌漿期，小麥需水1500 ~ 1800米3 /公頃，供水應保證滿足小麥需要和玉米出苗的土壤濕度。Many spikelets and good grain - filling were the direct factors for the high yield of sscmts in hybrid rice, and those high - yielding factors relied on high quality seedlings, sturdy individuals, high quality population and vigorous later growth
「兩超」栽培高素質的「超多蘗壯秧」和本田期健壯的個體生長是其穗足、穗大粒多的前提，而其高質量的群體結構和明顯的後期生長優勢是其籽粒灌漿結實良好和單穗重提高的物質保證。Abstract : the pot - experiment shows that the coated - and mixed - fertilizer applied to rice only once can meet the need of rice in its various growth periods and increase the yield of rice
文摘:盆栽試驗表明，一次性水稻專用塗層復混肥一次性施用能滿足水稻各生育期的需要，並能促進養分由稻稈向穀粒的轉移，提高成穗率和產量，使用方便，節省勞力，有較好的推廣應用前景。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。The results showed that both inadequate and excessive nitrogen application accelerated the decreasing process of leaf area index ( lai ) and chlorophyll content at later growth stage, which led to earlier leaf senescence
結果表明，氮肥用量不足或過量均加速了生長後期葉面積系數及穗葉葉綠素含量的下降進程，使葉片提早衰老，但二者作用機制不同。分享友人
