一、目的和意义种子的性状,首先指品种的性状,第二是指种子的质量。所以,选用什么样的品种,使用什么质量的种子,与农业生产的关系极为密切。搞好农作物品种区划,就能为确定育种(引种)目标,有计划地繁育和提纯复壮优质种子,因地制宜地推广优良品种,提供科学依据。品种布局区域化,是充分发挥品种的优良种性,保持农作物稳产丰产的重要措施;同时,对于调整农作物种植结构,提高种植业的经济效益,满足社会和市场对农产品的需要,都具有重要意义。
First, the purpose and significance of the traits of seeds, first of all refers to the traits of varieties, the second refers to the quality of the seeds. Therefore, the choice of what kind of species, the use of what kind of quality seeds, and the relationship between agricultural production is very close. If we do a good job in the division of crop varieties, we will be able to breed and purify high-quality seeds in a planned manner and popularize fine varieties according to local conditions in order to determine the goal of breeding (introduction) and provide a scientific basis. The regionalization of variety layout is an important measure to give full play to the fine variety of varieties and maintain stable and high-yield crops. At the same time, it is of great significance to adjust the planting structure of crops, increase the economic benefits of planting industry and meet the needs of society and market for agricultural products .

语文教学中的探究是指学生在教师的引导下，按照一定的任务或目标，采用一定的学习策略，独立阅读文章、观察生活、妥善表达、摄取知识、总结规律，并在这一过程中逐渐培养起良好的学习习惯和创新能力。教学中，笔者常采用以下几种方式引导学生的语文探究性学习。 一、合作学习促进探究 在教学中采用小组合作学习的方式，形成了教师与学生、学生与学生之间的全方位、多层次、多角度的交流模式，使每位学生都有机会发表自己的观
识字教学是低年级语文教学的重头戏，也是教学的难点。教学识字时，如果教师采用填鸭式教学法，让学生被动接受，那么久而久之教师授课时会感到缺乏激情，同时学生也会感觉学得很枯燥、索然无味。事后所授知识不能够很好地被消化吸收。日积月累必然会丧失对写字的兴趣，成为母语学习的一大绊脚石。当务之急是教师必须变换多种方法和手段进行识字教学，以激发学生的识字兴趣，同时培养良好的学习习惯。俗话说：“兴趣是最好的老师。”
