草根英雄

作品简介：

小草是最常见的小植物，常被踩踏，同学们很少了解小草有什么作用。本作品从介绍黄河开始，深入浅出，了解小草是如何保护黄河。通过“草根水土保持实验”，“小草保护水土流失冲刷实验”，“小草防风沙实验”，加深小草在大自然中的重要性。通过作品了解小草不仅美化环境，吸收二氧化碳，放出氧气。增加土壤蓄水能力，控制水土流失，防风固沙。没有小草的默默付出，河水就会变得浑浊，家园将会黯然失色。大家向默默奉献的小草致敬。

Abstract：

Grass is the most common small plant, and it is often trampled on. Students rarelyunderstand the role of grass.

This workstarts with an introduction to the Yellow River, and explains in simple terms,how Small grass protects the Yellow River. Through the "Grass Root Waterand Soil Conservation Test", the "Small Grass Protection Water andSoil Erosion Erosion Test", and the "Small Grass Anti-wind and SandTest", the importance of the grass in nature has been deepened.

Through the works, we understand that grass not only beautifies the environment,but also absorbs carbon dioxide and releases oxygen.Increase soil water storagecapacity, control soil erosion, and prevent wind and fix sand. Without the silent contribution of the grass, the river will become muddy and the home will be overshadowed. Everyone pays tribute to the silently dedicated grass.
