在杂交水稻汕优63始稳期,用15mmol/LCa(2+=)喷施叶面,能增加抽穗结实期间主茎旗叶的叶绿素和可溶性蛋白质含量,提高超氧物歧化酶(SOD)的活性.降低丙二醛(MDA)含量.延缓叶片衰老;同时,Ca(2+)能增加主德的实位数、结实串和千粒重,从而提高谷产量.
In the beginning of hybrid rice Shanyou 63, the leaf chlorophyll and soluble protein content increased with the increase of superoxide dismutase (SOD) active. Lower malondialdehyde (MDA) content. Delaying the leaf senescence. At the same time, Ca (2+) could increase the real number of main virtues, strengthen the string and 1000-grain weight, and thus increase the grain yield.
