Methods and systems that employ hybrid fluid flow profiles for optimized movement of materials through channel networks. These systems employ hybrid pressure-based and electrokinetic based flow systems for moving materials through interconnected channel networks while maintaining interconnection among the various channel segments. In particular, the invention is generally directed to channel networks where flow in a first channel segment is driven by pressure flow with its consequent parabolic flow profile, while flow in an interconnected channel segment is dominated by electrokinetic flow with its consequent plug flow profile. The invention also provides channel networks wherein fluid flow in channel segments is driven by both pressure and electric field and the multiple species contained in a fluid plug are separated by altering the applied pressure and electric fields in the various channel segments of the channel networks.

After being applied, the bio-organic fertilizer has the effects of effectively improving soil structure and improving soil fertility; the planted vegetables and fruits are excellent in quality and low in pesticide residues and have small difference in yield in comparison with a general fertilizer application method; the bio-organic fertilizer has the advantages of promoting wide-range popularization of organic agriculture and achieving remarkable economic benefits and social benefits.

The present invention employs a mass analyzer comprised of a pair of permanent magnets to select a desired species from multiple species within a ribbon type ion beam. These permanent magnets provide a substantially uniform magnetic field of adequate magnitude in a small region not attainable with electromagnets that applies a specific force in a desired direction. The force is applied to passing particles of a ribbon ion beam and causes paths of the particles to alter according to their respective mass. As a result, a selected species can be obtained from a beam by the force causing rejected species and/or contaminants to fail passing through the mass analyzer (e.g., by impacting the magnets themselves and/or another barrier present in the analyzer). As a result of the mass analyzer, dopant/species sources that generate multiple species can be employed instead of sources that only supply a single dopant/species.

In addition, the seedling method is simple, and the cost is low. A plurality of different kinds of flowering peach scions can be grafted on each mountain peach rootstock seedling, so that the single-plant grafting survival rate can be enabled to reach up to 99%. A cultivated grafted seedling has multiple species in one plant, so that better viewing values are brought when the cultivated grafted seedling is in blossom. Magnetic field treatment is carried out on the scions before grafting, division and differentiation of cells at a notch can be promoted, the wound healing ability is improved, the healing time is shortened, growth of the scions can also be promoted, and the grafting survival rate is improved. The method disclosed by the invention can complete grafting of flowering peach in the same year when the mountain peach rootstock seedling is cultivated, thereby greatly shortening the seedling time, and improving the efficiency and the market competitiveness.
