Abstract: The present disclosure relates to a simplified cultivation method without wheat-corn rotation system in Huang-huai-hai Plain. Aiming at making the most of regional light, temperature and water resources to increase the annual wheat-corn grain yield, the method optimally integrates cultivation technologies for two crops to achieve the objective of complementary, comprehensive and balanced annual grain production. The technical core of the method is as follows: directly planting corn with minimal tillage under no soil ploughing but straw mulching after corn harvest, and directly planting wheat with minimal tillage under no soil ploughing but straw mulching after wheat harvest, thereby realizing zero crop rotation in annual wheat-corn planting in the Huang-huai-hai Plain, making the most of light and temperature resources and increasing regional annual grain yield.

Abstract: Systems and methods are provided for the manipulation of a polarizable object with a pair of elongated nanoelectrodes using dielectrophoresis. The nanoelectrodes can be carbon nanotubes and are coupled with one or more time-varying voltage sources to create an electric field gradient in a gap between the nanotubes. The gradient induces the movement of a polarizable object in proximity with the field. The nanotube pair can be used to trap a single polarizable object in the gap.
