Silicon fertilizer is a kind of mineral fertilizer mainly containing calcium silicate. Its raw material is industrial waste (water quenching slag), which has a wide application range and remarkable application effect. The development of silicon fertilizer and the development of comprehensive application technology were established in the Tianjin Science and Technology Commission in 1996 and included in the key agricultural research projects.
Development and production of silicon fertilizer:
1. Established a silicon fertilizer production plant and a silicon fertilizer production line with an annual output of 25,000 tons. The small sand grain silicon fertilizer produced by the small sand grain silicon fertilizer production process has lower cost, convenient use and good effect than the domestic similar powder fertilizer.
2. Completed the development and application of high-efficiency composite additives, so that the utilization rate of main elements (Si, Ca, Mg) in silicon fertilizer is increased to 60-70%, which is more than twice that of similar products. 3. The silicon-calcium fertilizer, a new product of silicon fertilizer, has been developed and developed, and its application range is wider, and the effect of increasing disease resistance and pest control is more remarkable.
Comprehensive application technology development completed: A number of application effects tests on multiple crops were completed.
1. Completed the application test of silicon fertilizer under the condition of silicon content in different soils, and determined the critical value of soil available silicon (rice) to be 300mg/kg;
2. Completed the experiment of different application rates of silicon fertilizer, and found the best application amount of the main crops of grain, vegetables and fruit, namely 50kg/mu of grain crop and 50-75kg/mu of fruit and fruit;
3, completed the test of different varieties of silicon fertilizer, with a small sand-grain type of silicon fertilizer below 2mm, low cost and good effect;
4. The experiment of different application methods of silicon fertilizer was completed, and the effect of the base fertilizer was the best.
5. Completed the research and application of silicon fertilizer to control the cadmium pollution of heavy metal elements. Applying silicon fertilizer in the sewage irrigation area can significantly reduce the cadmium content in agricultural products.
The fine-grained (small sand-grain) silicon fertilizer and high-efficiency composite additive developed in this project are the first in China, and the technical indicators are at the leading level among similar products in China. The project systematically carried out farmland application test research and obtained a large amount of data. It has a guiding role in the large-scale application and application of silicon fertilizer. The project is mature in technology and has entered the stage of large-scale production and application. It can be promoted and applied in areas lacking silicon and calcium deficiency in the country. The project has been in operation for 5 years and has accumulated 12,000 tons of silicon fertilizer. It has an application area of ​​more than 200,000 mu in 14 provinces and cities such as Tianjin, Beijing, Hebei and Shandong, and has significant economic, social and ecological benefits. There are problems: Silicon fertilizer is a new type of fertilizer, farmers are still very strange, and the proportion of applied area is very small. In the future, it should focus on the development of compound fertilizer for silicon fertilizer and increase the propaganda of silicon fertilizer.
