钾对春小麦籽粒蛋白质形成期氮素利用的影响—(K.Koch及K.Mengel),《Agronomy Journal》’1977,69,№.3,477—480 一些研究者报导,禾谷类在高氮量下还需提供充足的钾,才能得到高的籽粒产量。氮和钾在籽粒形成中的生理关系还不十分清楚。为此进行试验,以研究灌浆期钾对氮在
Effect of Potassium on Nitrogen Utilization during Grain Protein Formation in Spring Wheat - (K. Koch and K. Mengel), Agronomy Journal, 1977, 69, No. 3,477-480 Some researchers report that at high nitrogen levels Need to provide sufficient potassium to get high grain yield. The physiological relationship between nitrogen and potassium in grain formation is not well understood. To this end, experiments were carried out to study the effect of potassium on nitrogen during grain filling
