Building strong roots and vigorous seedlings is an important guarantee of high yield and good quality.
The root system is the foundation of crop growth and development. Only when the root system is robust are nutrients sufficient and the crop healthy! And soil is the fundamental reason determining whether the root system is in good condition.

Therefore, creating a soil environment suitable for root growth is the fundamental condition for high yield and good quality in crops. So, from which aspects do we usually start to improve the soil?
1. Increase the application of biological bacterial fertilizer
Regularly applying microbial bacterial fertilizer can improve soil structure, break up soil compaction, activate nutrients fixed in the soil, and provide crops with complete nutrition. It can also inhibit or kill harmful bacteria in the soil, improve crop resistance, prevent infection from soil-borne diseases, and comprehensively enhance the crop's ability to resist pests and diseases.

2. Adjust soil pH
Long-term unreasonable application of chemical fertilizers and pesticides leads to severe soil acidification or alkalization, causing frequent root rot and dead plants in crops. Therefore, adjusting soil pH is very important, and soil pH can be adjusted by applying medium and trace element bacterial fertilizer.
3. Increase organic matter
Appropriately increasing humic acid fertilizer, while enriching the soil, promotes the formation of aggregate structure, making the soil loose and breathable, which is beneficial to the growth and activity of microorganisms and promotes the development of crop roots.

4. Reasonable drainage and irrigation
When watering, reduce flood irrigation and adopt drip irrigation or frequent light watering, so as not to damage the soil structure and affect the growth of crop roots. The drainage system should also be improved to avoid waterlogging and root suffocation during the rainy season.
5. Intertillage and soil loosening
Proper intertillage and soil loosening are very beneficial to root growth and development and the improvement of resistance, especially at the seedling stage. When the root function of crops is not fully developed, timely soil loosening can raise ground temperature, increase soil air permeability, and promote the rapid development of seedling roots.
