Characters of corn hybrid population growth types at IV evolution stage and its evolution characters and trend in Hebei-Shandong-Henan summer corn plantiug zone were analyzed in this paper.
运用群体生育型特征与演化的观点,分析了冀、鲁、豫夏玉米区玉米杂交种群体生育型演化进程至端的第Ⅳ演化阶段群体生育型基本特征与演化特征及其演进趋向,结果表明,第Ⅳ演化阶段群体生育型基本特征表现为株型紧凑或半紧凑,穗位叶适中,雄穗分枝较少,抗倒性和抗斑性优良,籽粒长,出籽率高;其演化特征主要由穗粒结构与第一叶面积、生育日数决定,其穗长演化将趋于稳态,穗行数、穗粗、百粒重、行粒数与第一叶面积、株高将呈现较明显的持续演进态势,其中生育日数、行粒数和株高将分别向早熟、多粒和高棵方向回归。
Based on EPMA analysis of arsenopyrite and the phase diagram of coexisting minerals pyrite-arsenopyrite,we conclud that temperature of the main mineralization stage is stable within 300~450℃.
本文通过主要矿化阶段热液矿物毒砂成分的测定,利用相图中共生金属硫化物稳定温度范围得出主要矿化阶段的温度为300~450℃,它比通过石英流体包裹体测得的均一温度更准确地代表成矿流体的温度,由此温度平均值计算出的氢氢同位素能准确判断初始流体的来源。
