我校是设在农村的一所全日制初级中学,学生都来自农村,98%以上是劳动人民的子女。毕业后除一小部分升入高一级学校外,大部分都回生产队参加农业生产。为了适应农业生产需要,我校开设了农业生产知识课,到现在已经有好几年了。我们曾有计划地开辟了实验园地的活动。目前我校有三亩实验园地,结合当地的生产特点,按不同季节,组织各年级学生种植水稻、棉花、小麦、油菜等四大作物。上学期我们种了一亩半水稻,其中一亩种“农垦58号”;作高产试验,半亩种“千三穗”、“白芒短种”、“老来青”等品种,作品种对比试验。棉花也种了一亩半,大部分是“岱字15号”棉,分别以每亩5000、6000、7000株,作不同密度与产量关系的对比试验,一部分还种了“海岛棉”和“彭泽棉”,作杂交育种试验。水稻、棉花长 Our school is a full-time junior high school located in rural areas.
