小麦品种鄂恩一号和7023生期规律的对比观察与分析

通过对豫南小麦当家品种鄂恩一号和种植多年的7023的对比观察,找出二者在生育规律上的差异,进而分析在栽培措施上的异同。与7023相比,鄂恩一号出叶速度快,容易形成壮苗;抽穗后绿叶保持时间较长,有利后期光合作用;年前分蘖数比例大,总分蘖及成穗数没有7023多;幼穗分化开始早,进程快,小穗数及穗粒数比较少;开花早,灌浆时间长,灌浆强度大,子粒大,千粒重高。基于这些特点,提出了十月下旬播种,三叶期、药隔形成期追肥,四分子期根外喷肥,加强后期管理等针对该品种特性的栽培措施。

A Comparative Observation And analysis on the Developmental Regularity in Wheat Variety of En-1 and 7023

During mang years comparison and abservation of wheat En-1 and 7023 in South Henan,we found the differ and the same of the two wheat variety in regularigy of growth and development,E-1 has more advantage over 7023, such as: the leave-growth faster, which is easier to get strong young plants. The green leave can keep longer time after heeding out. And it is helpful to later photosysthesis. Before the Spring Festival the;proporation of its' tillering of seeding is more, the number of total tillering and developing spike is less. The small spike divide early and its' stage is shorter. The number of small spikes and kernels in spike is less. Its' flower blooms early and milking stage is longer.The intensity of milking and the weight of looo kernel are great.Based on this, we obtained the culture of kernel row on the late lOdays in Oct. And applied additional manuring during the time of three blade -formed another division-formed stage. Applied manuring out side the root during tetrad stage.
