Now, from Yunnan province in southwestern China to Jiangsu province in the east of China, many farmers use biological bacterial fertilizer instead of chemical fertilizers when they add fertilizer to crops. Experts say that the promotion of the use of bacteria-based fertilizers in rural China is an important way to prevent agricultural production from polluting rivers and lakes. This pollution is caused by a large amount of chemical fertilizers and pesticide residues in the farmland that flow into rivers and lakes with rainwater. According to information provided by environmental protection agencies, a considerable part of industrial and urban domestic sewage from various parts of China is discharged into rivers and lakes after treatment by sewage treatment plants. The degree of pollution to water bodies has been significantly reduced, but this also causes pollutants from agriculture. The harm caused is even more pronounced. In the recent pollution of rivers and lakes, three quarters of the sources of pollution come from agriculture. Guo Huiguang, a senior engineer at the Yunnan Institute of Environmental Sciences, said: "The large-scale use of fertilizers and pesticides by Chinese farmers began in the mid-1960s. For decades, chemical fertilizers have greatly increased China's grain production, but it has also caused considerable growth. The negative impact is that most of the farmers are directly spraying fertilizers and pesticides into the fields, which not only can not provide continuous nutrients to the crops, but also wash off most of the fertilizers and pesticides when it rains and waters. Rivers, lakes and seas, where these contaminated waters are consumed by people, can be described as harmed.†The long-term excessive use of chemical fertilizers has caused the consolidation of many farmland in China, and the effect of fertilization has declined, which in turn has brought about a decline in product quality. The direct expression of the product's taste is poor. Therefore, many people complained that "vegetables are not as tasty as they once were." In order to overcome the many negative effects of using chemical fertilizers, Chinese scientists are studying the use of bacterial fertilizers instead of fertilizers. Zhang Tao, director of the Science and Technology Industry Department of the Yunnan Provincial Institute of Environmental Sciences, said that in cooperation with Tsinghua University, they have treated some bacteria to make them biological bacteria capable of solidifying the soil and keeping nutrients. The fungus fertilizer will not pollute the environment like traditional chemical fertilizers, but also provide balanced and comprehensive nutrition for the plants, make the plants grow more robust, the quality is significantly improved, and the probability of occurrence of diseases and insect pests is greatly reduced. Bio-fertilizer is to grind the crop's straw into the fermentation tank, add the bacteria, and after mixed fermentation with the livestock and human feces, it is applied to the field. These bacteria are able to better solidify the nitrogen in the air and soil, while having the characteristics of decomposing phosphorus and potassium. Nitrogen, phosphorus, and potassium are essential nutrients for plant growth, and they are also the main substances that pollute water sources. After the decomposed nitrogen, phosphorus, and potassium, the water pollution will be very low. According to Dai Li, an engineer who participated in the experiment, experiments on applying biological bacterial fertilizers to vegetables showed that they grew better than chemical fertilizers, and the characteristics of the fungus fertilizers were that they could continuously supply nutrients. She said that unlike chemical fertilizers, bacterial fertilizers do not accumulate on plant leaves or in soil, and they will flow away when precipitation is encountered. It can convert solid nitrogen into easily absorbed ionic nitrogen, which softens the compacted soil. In order to make the use of fungus more convenient, the biological fungicide developed in Jiangsu Province is almost the same as that of chemical fertilizers. There is no smell of farmyard fertilizers, and the cost is slightly lower than that of chemical fertilizers. Now, many places in China have restricted the use of chemical fertilizers and pesticides. Jiangsu Province clearly stipulated the amount of chemical fertilizers used in farmland along the Taihu Lake area. Yunnan Province has also taken compulsory measures this year, reducing the use of fertilizers and pesticides by 20% in previous years.
