Long-finned koi successfully bred at aquatic improved variety trial farm
In Renhe Village, Bingcun, Meixian, there is a farmer named Qiu Dong. Two years ago, he suffered a natural disaster while growing golden pomelo, and nearly 400,000 yuan of investment was almost completely lost. He then switched to raising grass carp, but an 8-mu pond earned him only about two thousand yuan in a year, unable to make ends meet, and he fell into no small amount of debt, with his finances in dire straits. One day, a fisheries expert appeared and showed him a kind of fry, which brought a turning point in his life. Now, he has become a locally somewhat well-known "fish" farming specialist, with an annual net income of more than 20,000 yuan, and has led three or four neighboring relatively poor villagers to prosper together.

Degradable-film controlled-release fertilizer for rice successfully developed in Hunan Province
The Soil and Fertilizer Institute of Hunan Province has developed a degradable-film controlled-release fertilizer for rice that can be widely applied in rice-growing regions of China with no side effects. Using natural and semi-natural polymer materials as the main coating components and adopting a self-developed new fluidized dual-spray-bed coating process, the Soil and Fertilizer Institute of Hunan Province developed a degradable-film controlled-release fertilizer whose nutrient release can be artificially controlled within 30 to 330 days. This controlled-release fertilizer is non-toxic, completely degrades within 2 years after being applied to the soil with no residue, and can reduce fertilizer pollution of the atmosphere, soil, water bodies and other environments.

Self-pesticide potatoes successfully cultivated in Belarus
Scientists in Belarus have become the first in the world to cultivate potatoes that can automatically kill pests. A scientist involved in the research said that through experiments they successfully transplanted a special gene into the potato plant, and this gene can continuously produce a toxin lethal to the Colorado potato beetle (the toxin is harmless to humans). Therefore, when the Colorado potato beetle begins to damage the potato stems and leaves, the toxin quickly penetrates the insect's body and poisons it to death.
