Canadian scientists develop a new agricultural research management framework from ecological functions
According to the latest issue of the Journal of Applied Ecology, Canadian scientists have developed a new agricultural research and management framework by studying functional trait ecology to understand short-term agricultural yields and long-term sustainability and biodiversity. The relationship provides a new way.
Mane Isaac, a researcher in the Canadian agroecology and development field and associate professor at the University of Toronto, Scarborough, said that the focus of ecological function traits is on the response and impact of plants to environmental changes, not just on the analysis of their genetic characteristics or Measure its output.
The new research framework will help answer many questions, such as how do certain plant varieties achieve nutrient cycling? Can you resist pests? Can you mitigate the effects of drought? Isaac said that environmental changes and agricultural practices can affect the size of crops, the characteristics of roots and leaves, and their reproductive patterns. New methods based on traits will reveal the causes and consequences of these changes, in addition to the effects on yield, as well as the interaction of crops with other plants, insects, microbes and the surrounding environment.
The promotion of commercial crops often leads to an increase in the single planting model, while the single planting model can lead to severe environmental damage while maximizing production. Single-crop crops become more vulnerable and less resilient in the face of drought, disease, alien species and herbivorous pests, and increasing biodiversity alone does not help.
Isaac said the new research framework will help promote understanding of ecological models in natural and experimental ecosystems, creating a new blueprint for applying this approach to agriculture. The new framework will speak with data to help select plant species in agricultural production systems so that they can fully complement each other and better adapt to adaptability and sustainability.
Concerned about surprises
Si3N4 ceramic is an important structural material. It is a kind of super-hard material. It is lubricious and wear-resistant. It does not react with other inorganic acids except hydrofluoric acid. It has strong corrosion resistance and resistance at high temperature. It is also resistant to thermal shock. It is heated to above 1,000 °C in air, and is rapidly cooled and heated rapidly without cracking. It is precisely because of the excellent properties of Si3N4 ceramics that it is often used to make bearings. Mechanical components such as gas turbine blades, mechanical seal rings, permanent molds, etc. If the Silicon Nitride Ceramics with high temperature resistance and heat transfer resistance are not used to manufacture the heating surface of engine parts, not only can the diesel engine quality be improved, fuel can be saved, but thermal efficiency can be improved.
