As we all know, my country is the first country to use kaolin to make porcelain. It is famous at home and abroad for the Gaolin Village, which was discovered in Fuliang County, Jiangxi Province and was rich in kaolin, and has the English translation of "kaolin". Kaolin is a clay mainly composed of kaolinite. Its mineral composition contains a large amount of quartz and hydromica minerals besides kaolinite. Internationally, this kind of special clay is called "kaolin". The appearance is generally white or off-white, and it is the main raw material for making porcelain and making white paper.
In recent years, with the advancement of science and technology, its application range has become more and more extensive. According to the relevant information: Researchers from an institute under the US Department of Agriculture found that kaolin clay diluted and applied to grapevines can prevent or reduce pest infestation. If apples, pears and other fruit trees are sprayed with kaolin aqueous solution, it can reduce the heat radiation of strong sunlight on the trees in summer, thereby reducing water evaporation and improving the fruit yield of fruit trees; if the use of kaolin clay is widely used in orchards, pesticides can be reduced. More than half of the dosage is beneficial to reduce the cost of fruit production, and the safety of fruit consumption is also improved.
At the same time, American agricultural researchers also found that adding a certain amount of kaolin to pesticides to make a colloidal mixture and spraying it on crops can not only reduce the amount of pesticides, but also prolong the killing time. If grains, vegetables and other crops are also sprayed with kaolin clay mixed with pesticides, the cost will not only be greatly reduced, but also the residues of crop pesticides will be greatly reduced.
