First, there is a clear principle of foliar leaf structure foliar supply, the basic structure of the leaf blades, petioles, stipules. Leaves also includes epidermis, mesophyll foliar fertilizer prices, veins. Mesophyll generally divided into palisade and spongy tissue (that C3 plants and C4 plants are different). Studies have shown that long carbon chain fatty acid of the stratum corneum from a composition having a hydroxyl group and a carboxyl group foliar species, hydroxyl, carboxyl and hydrophilic groups molecule gap on this polymer molecules can penetrate into the leaf so that an aqueous solution of within, of course, fertilizer, foliar stomata leaf surface is more convenient to enter the blade passage. Urea fertilizer substances epidermal cells of the stratum corneum has a softening effect, can accelerate the penetration of other nutrients, so foliar urea become an important component.
