Existing Problems

Rice is an important crop in many areas, but it will be damage by Pomacea Canaliculata and strong wind, causing over a billion dollars of agricultural damage every year. Farmers used a lot of pesticides to kill Pomacea Canaliculata, which caused another ecological catastrophe, which affected the environment near the farmland and also affected the quality of rice.

Design Information

Crop Protector is a seedling's stake to prevent seedlings from being damaged by Pomacea Canaliculata, dumped, and provides nutrients. The shell is made from straw fiber, which can stabilize the root of the seedlings and prevent it from dumping in a strong wind, the top is made by adding rice bran and tea seed meal, which can reduce the damage of Pomacea Canaliculata and promote the initial growth of seedlings. The straw fiber, rice bran, and tea seed meal which from agricultural waste are rich in nutrients can be decomposed in the soil and become an organic fertilizer to help the growth of the seedling, and then achieve friendly recycling planting. Crop Protector can be used to transplant rice seedlings, or it can be linked into a form for mechanical transplanting, providing different planting needs in a different areas.

Mechanized Transplanting Process

Use Crop Protector 

linked into a disk form 

for seedlings.

Place the entire plate of Crop-

Protector above the rear plate 

of the rice transplanter.

When the rice transplanter 

the operation, it will hook a 

single Crop Protector.

The hooked Crop 

Protector will be 

separated from the 

entire Crop Protector.

Crop Protector will de-

compose and turn into 

nutrients to help crops 


Crop Protector can protect 

the crops when the crop are 


The rice transplanter will 

insert the hooked Crop 

Protector into the soil.

Material Information

The Up Half Material -

The tea seed meal not only can be used to prevent the intrusion by Molluscs which have the mucus, but also can decompose and produce rich of nutrients to help crops grow.

The Down Half Material -

Straw fiber can provide soil organic, and the nutritional elements will release after decomposition. It can supplement soil nutrients, and have the function of adjust soil temperature, which can improve the growth environment of crop roots and enhance crop growth.

Material Recycle

Acquiring agricultural waste from 

farmers, and crushing the straw 

fiber, rice bran and tea seed meal 

into Crop Protector.


Crop Protector can prevent crops been damaged from Pomacea Canaliculata and strong wind during the growth of the seedling.


After the harvest, collect the 

agricultural waste and re-make 

the Crop Protector.


Crop Protector decompose

naturally into the soil and become the nutrients to help crops grow.
