玉米盖膜育苗移栽是近年发展起来的一项新的玉米栽培技术。在生产上已显示出它巨大的优越性,得到迅速的推广和应用。这一技术主要通过以下方面达到趋利避害、抗灾增产的目的。 1、提早播种期。玉米盖膜育苗移栽,可以在气温还不足玉米安全发芽出苗的10—12℃以前的一段时间,依靠盖膜增温,人工创造一个适宜玉米发芽出苗的温度环境,从而明显地提早玉米的播种期。并给予玉米幼苗生长以比大田正期直播更为优越的环境条件,从而有效地提前开花授粉和灌浆的时期。据万县地区和宝兴县多年的实践证明,采用玉米盖膜育苗移栽,通常可在大气温度回升到6—7℃
Corn cover film seedling transplanting is a new corn cultivation technology developed in recent years. In the production has shown its tremendous superiority, get rapid promotion and application. This technology is mainly through the following areas to achieve the purpose of avoiding disadvantages and increasing output. 1, early sowing period. Corn cover film seedling transplanting, temperature can be less than the safe germination of corn sprouting 10-12 ℃ before a period of time, relying on the cover film warming, artificially create a suitable temperature for emergence of corn germination environment, which significantly earlier sowing of corn period. And give corn seedlings grow more favorable than the direct broadcast field weather conditions, thus effectively flowering in advance pollination and grouting period. According to Wan County and Baoxing County, many years of practice has proved that the use of corn seedling transplanting, usually in the atmospheric temperature rose to 6-7 ℃

在教育界，“人文教育”一词用得十分普遍。然而，究竟什么是“人文教育”，却是一个仁者见仁、智者见智的问题。一般来说，人们谈到的人文教育，并没有一种统一的定论，常常表达着多种含义。此刻，我仅站在一个普通教师的角度谈谈自己在新课程改革中，对如何以人文教育为本，全面提升学生素质作个探讨。在我看来人文教育绝不仅仅是文、史、哲的学科教育，其核心应是使人成为“人”的教育。这是针对教育中无视人，把人当作工具或者强
一、建设小康体育的社会背景探析 1.城乡居民收入水平稳步增长。从农村居民收入来看，1979年到2007年平均每年实际增长7.3%。农民收入水平实现温饱有余，部分地区已实现小康。从城镇居民看，城镇居民收入加速增长，2007年，城镇居民人均可支配收入7860元，城镇居民已经整体上实现小康。 2.农村居民生活质量还需进一步提高。全面建设小康社会，农村农民的小康是至关重要的，农村小康体育也将是未来
增强青少年体质、促进青少年健康成长，是关系国家和民族未来的大事。如何引导广大学生自觉走向操场，走到阳光下，走到大自然中去，积极参加体育运动，让学校的“阳光体育”真正阳光起来呢? 一、锻炼时间要保证 首先，学校要把学生每天一个小时的体育活动时间列入课程总表和各班课程分表，一、二年级每周4节体育课，三年级以上每周3节体育课，每天上午有课间操，下午有课外活动；要求教师要严格按课程表上课，任何
