摘要: 钾对植物的抗旱性有着密切的关系。我们就不同土壤水分条件下钾肥对小麦的生理效应及其对抗旱性的影响作了初步研究。在缺钾的土壤中,无论是充分供水或干旱,施用钾肥均能促进植株对氮和磷的吸收和运转,提高叶水势、叶片持水力,从而提高土壤水分的利用效率。在生长期间,钾能提高叶片的叶绿素含量,增大叶面积,延长叶的功能期,提

Abstract: In pot trials in 1982~1983,winter wheat cv.Wu-nong 132 was grownin a potassium-deficient soil.The effect of applying potassium asfertilizer before sowing under two soil moisture levels was studied,highlevel(w)was 70% and low(d)was 35% of field water capacity,whichhad been maintained at seedling sta
