Organosilicon additives help transform saline-alkali land into high-yield fields, facilitating breakthroughs in agriculture in arid areas

1.New breakthroughs in soil treatment through science and technology bring new life to saline-alkali land
In the arid and semi-arid regions of northwest China, the management of saline-alkali land has always been a difficult problem for agricultural development. In recent years, agricultural organosilicon additives have demonstrated unique advantages in the improvement of saline-alkali land and have become an important means of scientific soil treatment. Taking a certain saline-alkali land demonstration area in Northwest China as an example, by adopting the "organosilicon + water and fertilizer integration" technology system, the once barren land with white alkali has been transformed into high-yield fields with an output of over 1,000 jin per mu, opening up a new path for agricultural development in arid areas.

2. Targeted desalination technology reconstructs soil ecology
The core role of silicone additives in the management of saline-alkali land lies in the construction of a "targeted desalination" system. Its special molecular structure can change the surface tension of water, promoting the rapid deposition of salt ions in the soil below the root zone of crops. Combined with the drip irrigation system, it forms a "light salt protection circle for the root system", effectively preventing deep salt from moving upward. In the moderate saline-alkali land experiment, the corn fields treated with organosilicon improvers showed significant advantages such as more vigorous growth, greener leaves and thicker stems, and the physical and chemical structure of the soil was significantly improved.

3. The dual benefits of water conservation and pesticide reduction increase the income from planting
In agricultural production in arid regions, the water-saving and efficiency-increasing characteristics of silicone additives are particularly crucial. Data shows that the spray solution with organosilicon additives can reduce water consumption per mu by more than 30%, and when combined with drip irrigation technology, it can further reduce water evaporation loss. Meanwhile, the additives enhance the absorption efficiency of pesticides and fertilizers in saline-alkali land crops, reducing the use of pesticides by 30% to 50%. The application effect on salt-tolerant crops such as sunflowers and corn is particularly significant, greatly lowering the production input of farmers.

4. Technology integration and promotion expand application prospects
At present, the research team has formed an integrated technical system of "silicone improvers + salt-tolerant varieties + water-saving irrigation", and has screened out 61 salt-tolerant crop varieties in the northwest demonstration area and developed 19 key management technologies. Among them, the "organosilicon + amino acid" seed coating agent has increased the emergence rate of corn by more than 20%. Combined with the liquid nitrogen fertilizer efficiency enhancement technology, it has achieved a virtuous cycle of "less input and more output" for crops in saline-alkali land. Industry insiders say that this technical system is expected to be promoted and applied in more arid and semi-arid regions, providing important support for the comprehensive management of saline-alkali land.
