主 题:N_min residue spinach water and nitrogen recommendation
摘 要:Effets of conventional and optimized water and nitrogenmanagements on spinach (Spinacia oleracea L.) growth and soil mineralN (N_min) residues were compared in an open field experiment in whichwater balance method and N recommendation with the KNS-system wereincluded. It was shown that the conventional water treatment(seasonal irrigated amount: 175 mm) reduced spinach growth comparedto the water balance treatments (seasonal irrigated amount: 80 and 85mm) at he same N supply level due to N loss through leaching causedby excessive water supply.
