Abstract:

The kinetic cha racters of Zn in soi l and soybea n plant under so ybean, continuo uscropping st ress w ere inv estig ated by po t ex periments, field ex periment s and chemicalanalysis indo ors. As fa r as the av ai lable Zn in soil o f soy bean continuous cropping is totallyhig her but the uptake and accumulation o f Zn in soy bean plant is low er than that ofrota tio n in di fferent so ybean co ntinuous cro pping yea rs and di fferent g row th stag es, theva ri tio n is especially sig ni ficant in the cri tical full blooming-podding-seed fil ling vegetative stag e. The result s indicate tha t bio logica l availabili ty of soil Zn is no t high so thatthe co ntino us planting soy bean causes poo r g row ing condi tio ns and malabso rption o f nutrientelement s by it s root s. Therefo re, soybean continuo us cro pping should requi remore supply of soi l available Zn to meet i t s needs. The scientific g ro unds fo r reaso nablreg ula ting Zn nut ri tio n of so ybean continuo us cropping and alleviating continuo us croppingbarriers a re recommended by the study.
