Rice is one of the most important foods in the world, especially in Asia. However, in the early stage of planting, it is often caused by insect pests or strong winds that cannot grow well. Because this will cause a lot of loss of rice every year, we hope that this problem can be solved through design. Crop Protector is a seedling's stake to prevent being damaged by Pomacea Canaliculata and wind damaged. The shell is made from straw fiber, which can stabilize the root and prevent dumping in a strong wind, the top is made of rice husk and tea seed meal which can drive away from the Pomacea Canaliculata. These three materials from agricultural waste are rich in nutrients, can decompose in the soil become nutrients to help crops grow to achieve friendly planting. Crop Protector can be used to transplant rice seedlings or mechanical transplanting, providing different needs in different areas.
