INTERCROPPING: FEED MORE PEOPLE AND BUILD MORE SUSTAINABLE AGROECOSYSTEMS

Frontiers of Agricultural Science and Engineering 2021, Volume 8, Issue 3,   Pages 373-386 doi: 10.15302/J-FASE -2021398

Abstract:

Intercropping is a traditional farming system that increases crop diversity to strengthen agroecosystem functions while decreasing chemical inputs and minimizing negative environmental effects of crop production. Intercropping is currently considerable interest because of its importance in sustainable agriculture. Here, we synthesize the factors that make intercropping a sustainable means of food production by integrating biodiversity of natural ecosystems and crop diversity. In addition to well-known yield increases, intercropping can also increase yield stability over the long term and increase systemic resistance to plant diseases, pests and other unfavorable factors (e.g. nutrient deficiencies). The efficient use of resources can save mineral fertilizer inputs, reduce environmental pollution risks and greenhouse gas emissions caused by agriculture, thus mitigating global climate change. Intercropping potentially increases above- and below-ground biodiversity of various taxa at field scale, consequently it enhances ecosystem services. Complementarity and selection effects allow a better understanding the mechanisms behind enhanced ecosystem functioning. The development of mechanization is essential for large-scale application of intercropping. Agroecosystem multifunctionality and soil health should be priority topics in future research on intercropping.

Independent Development:The Way to Build up the Strength of a Country

Jin Lüzhong

Strategic Study of CAE 2005, Volume 7, Issue 7,   Pages 1-6

Abstract:

The paper expounds the significance of independent development in the fields of politics, military affairs, economy, security, science and technology, etc. It suggests that most of industries in China be provided with the capability of independent development and international competitiveness within 10〜15 years. It analyzes the possibility for achieving this goal. The paper also suggests that the environment favorable to independent development be created in the aspects of ideology, spirit, laws and regulations, policies, system as well as dissemination and public opinion.
