7. Beijing, China – CAU – P27 & Qinggang County, China – HAAS – P23
Demonstration of the techniques of salinity resistance improvement and nutrient loss reduction in vegetable substrate cultivation
Demonstrator: Cuihu soilless cultivation innovation factory in Beijing China
Type and volume of input materials/products
The technology effectively combined the improvement of salt resistance of vegetable cultivation substrate with the improvement of crop stress resistance.
Type & volume of output materials/products
Through the simultaneous control of substrate and crop, the salt resistance of crops can be improved simultaneously with the reduction of the availability of salt ions in the root zone, so as to maximize the absorption and utilization rate of input nutrients (nitrogen and phosphorus) of crops.
Nitrogen and phosphorus emission reduction technology centered on alternative measures of corn straw humification returning to the field
Demonstration Site: Qinggang county ( by HAAS – P23)
Type and volume of input materials/products：
Using humic straw and livestock manure as organic materials to replace some fertilizer nitrogen, and supporting by deep tillage and biological control technologies.
Type & volume of output materials/products：
With greenhouse gas emissions, nitrogen and phosphorus loss, and crop yield as the main measurement indicators, then parameters such as the proportion of organic material substitution and application time will be improved and optimized, and establish a nitrogen and phosphorus efficiency enhancement and emission reduction technology model under continuous corn cropping conditions in black soil areas.
