1989年银南地区农技站从北京星火科技开发部偃师肥厂引进小麦高效多元素微肥在灵武县郭家桥乡清水沿村进行小面积试验,取得了明显的增产效果,深受当地农民的欢迎。一、试验方法 1.试验共设4个处理。①小麦拔节期(5月18日)喷多元素微肥1次。②小麦拔节期喷多元素微肥1次,抽穗期(6月2日)喷磷酸二氢钾1次。③小麦抽穗期喷磷酸二氢钾1次。④以不喷肥为对
In 1989, Yinnan Agro-Technology Research Station started a small-area experiment in Qingshui along the village of Guojiaqiao Township, Lingwu County, introducing high efficient multi-element wheat micronutrient from Yanshi Fertilizer Plant of Beijing Xinghuo Science and Technology Development Department and obtained obvious yield increase effect. Welcome. First, the test method 1 test a total of 4 processing. ① wheat jointing period (May 18) spray multi-element fertilizer 1 time. ② wheat jointing multi-element fertilizers spray 1, heading (June 2) sprayed with potassium dihydrogen phosphate 1 times. ③ wheat heading stage spraying potassium dihydrogen phosphate 1 times. ④ do not spray right

中国人喜欢说“九”.唐代诗人刘禹锡在《浪淘沙九首》里写道: 九曲黄河万里沙, 浪淘风簸自天涯. 如今直上银河去, 同到牵牛织女家. 民谣里说: 天下黄河九十九道弯. 实际上黄河的弯多得数不清,“九曲”或“九十九道弯”都只是用数字9来形容多. 在数学上,数字9有很多有趣的性质.例如,如果一个数的各位数字都是9,那么它的平方就会出现一种循环: 92=81,8 1=9; 992=98
