In recent years, problems such as acidification of soil, salinization, compaction, heavy metal pollution, decline in basic soil fertility, and degradation of cultivated land have occurred in many areas of China. The data show that the total area of soil degradation caused by non-point source pollution, soil erosion, salinization, soil fertility decline, etc. will be nearly 460 million hectares, accounting for about 40% of the total land area of the country. Song Furu said at the beginning: "Resolving soil problems depends on science and technology, and on the other. Products. In this regard, Silicon Valley agriculture is ahead of the agricultural industry, taking the lead in developing farmland soil pollution control technologies and products, and opening the door to China."


Starting from the goal of breakthrough in polluted soil management, the Silicon Valley Academy of Agricultural Sciences has developed a new technology for the treatment of slab soil activator fertilizer, organic silicon to control saline soil, acid soil conditioner fertilizer, and organic silicon to control heavy metal pollution. Soil passivator fertilizer and other products. Field trials have shown that this series of products can effectively control soil salinity, acidification and heavy metal pollution.


Song Furu said that the soil-producing nature of organic silicon forms the agglomerate structure of the soil, which solves the problem of soil compaction. The high-efficiency dispersibility of the product can increase the utilization rate of traditional fertilizers to over 80%, and the utilization rate of foliar fertilizer containing silicone can be More than 95%. The use of silicones improves soil conditions, not only increasing yields, but also improving the quality of agricultural products. If the plant is planted with silicone water soluble fertilizer, the yield per mu can reach 974 kg, which is the highest record in China's wheat history. The hybrid rice experiment in cooperation with Academician Yuan Longping achieved 1082.1 kilograms of organic fertilizer per mu last year, creating the highest yield record in the world.


Song Furu believes that green, environmental protection, high performance and multi-function are the development direction of China's fertilizer in the future, and it is also an urgent need to solve soil pollution. At present, there is no functional fertilizer for soil pollution in the world. After more than 20 years of research on silicone materials, Silicon Valley Academy of Agricultural Sciences found that silicone has many little-known properties. Good surface activity can effectively neutralize the pH of the soil, and also has dispersibility, water repellency and soil-friendly properties. The research and development of organic silicon can be used to control soil materials, which can control saline soil, acid soil and heavy metal contaminated soil. The sunflower was planted in the saline-alkali land in Inner Mongolia. After using the Silicon Valley fertilizer, the emergence rate reached 85%, the diameter of the disk was 30 cm, and the yield per mu reached 200 kg, which increased production and efficiency. In some areas in the north, the pH value of saline soil reached 8~10, and in the acidic soil in the south, the pH value reached 4.5. After using the fertilizer of Silicon Valley, the pH value of the soil can be corrected to neutral.


The most serious soil pollution is heavy metal pollution. So far, there is no technology to ensure that the treatment is up to standard and the technology can be promoted. Some experts pointed out that it takes at least 35 years to form a regular conclusion. “After many years of research, the Silicon Valley Academy of Agricultural Sciences believes that the treatment of soil heavy metal pollution should be adjusted, and there should be no more products that affect crop growth and secondary pollution appear in farmland. Under the guidance of this idea, the Silicon Valley Academy of Agricultural Sciences established a soil for governance. The scientific research team of heavy metal pollution has successfully explored the technology and direction to solve heavy metal pollution in soil. It is to use organic silicon to control heavy metal contaminated soil, restore soil health function, keep soil pH stable at around 7, and passivate heavy metal biological activity and reduce crop pair. Its absorption."


The pH value is an important factor affecting the pollution of heavy metal cadmium. For every 1 unit of pH reduction, the activity of heavy metals will increase by 100 times. The use of silicone active alkali in combination with fertilizers can make the pH of the fertilizer neutral, leaving free heavy metal ion contaminants outside the roots, becoming the first barrier to solve heavy metal pollution. Silicone treatment of heavy metal pollution can be quickly absorbed by crop cells on the leaf surface, which can inactivate the heavy metal cadmium ions and block the passage of cadmium ions. A tea garden in Jiangxi was blocked by heavy metal pollution, and the use of Silicon Valley fertilizers reached the EU standard and was exported to the EU market. In 2014, using Silicon Valley fertilizer in Nanyang, Henan Province, the heavy metal content in tobacco leaves also fell below the national standard.


Not only that, Silicon Valley Academy of Agricultural Sciences and Huazhong Agricultural University established a demonstration base for the treatment of heavy metal pollution in Hubei Public Security County, using organosilicon to control heavy metal pollution passivator functional fertilizer, effectively blocking the absorption of heavy metal cadmium by rice. After testing, the cadmium content of rice is 0.02 mg per kilogram, which is only one tenth of the national standard of 0.2 mg per kilogram. There is also an unexpected effect. The use of organosilicon to control heavy metal passivation agent to control soil pollution not only effectively reduces the cadmium content of rice, but also increases the yield per mu by more than 150 kilograms, and increases the total income by more than 400 yuan.


Harnessing heavy metal pollution is still a world problem. Japan is the first country in the world to discover that heavy metals in the soil cause pollution to the soil. However, for more than 40 years, it has not developed green, environmentally friendly, high-tech products to effectively control the heavy metal pollution of the soil. "China is the world's largest producer and consumer of fertilizers. We have the ability and wisdom to control soil heavy metal pollution and restore soil vigor. We have the ability to increase the production of agricultural products after heavy metal pollution, and improve quality." Song Furu said firmly .


Looking forward to the future, Song Furu is full of enthusiasm: "The history of the vast river, the industrious and wise ancestors of all generations, experienced the eternal years of the storms and snows, step by step to today's civilization, progress, brilliant... China's history is The history of farming culture. In the new historical period, China's agricultural development requires a group of people who have created history. We should all become history-creating people in different positions in the agricultural field. I am a rural person and a village official. The official is the peasant, how many homesickness, future dreams, I have to work hard to become a distinctive Chinese peasant."
