16% Exianqing is the first choice for controlling rice "small panicle head"
For many years, in some major rice-producing areas such as Jiangsu, the phenomenon of "small panicle head" (also called small-grain distorted panicle) has appeared continuously over many years under multiple varieties, multiple planting levels, and multiple ecological conditions in large-scale production. Its characteristics are: small panicles, small glumes, cracking of the inner and outer husks after grain filling, partial exposure of rice grains, and small grains with dark brown color. It is especially severe in the Lixiahe area, coastal areas, along the Huai River, along the Yangtze River, and hilly areas of Jiangsu Province. It is estimated that in recent years the affected area in Jiangsu Province alone has been about 100,000 hectares each year, reducing rice output by more than 100 million kg, and cumulatively causing about 500 million kg of rice yield loss.

Why is the golden-headed turtle called a masterpiece among turtles?
The golden-headed turtle, also known as the snake-eating turtle, is a specialty of China and originally lived in mountain streams south of the Yangtze River basin; it is now on the verge of extinction. The golden-headed turtle has a smooth, scale-free head, a short snout that does not protrude beyond the edge of the beak, an upper beak with a distinct notch, large eyes, a round and clearly visible tympanum, and a broad golden-yellow arc-shaped stripe behind the eye, hence the name "golden-headed turtle."
