Green nutrient cultivation cup

In rural China, the seeds of Camellia oleifera are usually used to squeeze edible oil. The seed residue after squeezing is called "tea seed cake". Because it is rich in nitrogen and other trace elements, people often use it as fertilizer. This is a seedling cultivation cup made of Camellia oleifera seed residue. It is mainly made of pressed seed residue and a small amount of straw (straw is mainly used for fixation). It is buried in the soil. After a period of time, it will gradually degrade to form the nutrients needed by plants, and it also has certain insect repellent and bactericidal effects. The production process of "Green nutrient cultivation cup" does not add any chemical materials, so green, healthy, environmentally friendly, and safe are its characteristics, and the cost of making it is very low. The secondary use of materials makes it turn waste into treasure.
