The most striking yuan longping grandpa's contribution.Commentator said aunt, he cultivated varieties of hybrid rice, the rice yield was improved greatly.We use seven percent of the world's arable land, to feed the world more than twenty-two percent of the population, yuen liledagong grandpa.
I also see a canopy model.The greenhouse can accurately control temperature, humidity and light, also can let flowers bloom in cold winter, melon and fruit fragrance.
The introction of color cotton aroused my curiosity.This kind of cotton in the boll opening has a different color such as red, yellow, green, cotton mills can directly use it spun out of the color line, weave colorful cloth.
Soilless culture technology is very great.Science and technology personnel to dissolve the various nutrients in the water, without soil, plants on the water, also can grow very strong.
On the way home, I can't help but think: with advanced science and technology, agriculture has changed so much!
星期六，我兴致勃勃地来到展览馆，观看农业科技成就展。
袁隆平爷爷的贡献最引人注目。讲解员阿姨介绍说，他培育出的杂交水稻良种，大大提高了水稻产量。我们用世界上百分之七的耕地，养活了全世界百分之二十二以上的人口，袁爷爷立了大功。
我还看到一个大棚模型。这种大棚能准确控制温度、湿度和光照，在寒冷的冬季也能让百花盛开，瓜果飘香。
彩色棉花的介绍引起了我的好奇。这种棉花在吐絮时就有红、黄、绿等不同颜色，棉纺厂可以直接用它纺出五彩线，织出五彩布。
无土栽培的技术也很了不起。科技人员把各种养分溶解在水里，不用泥土，植物靠着这样的水，也能长得十分茁壮。
回家的路上，我不禁想：有了先进的科学技术，农业的变化真大！
