叶面肥施加对马铃薯农艺性状及品质的影响
Effects of Foliar Fertilizer Application on Agronomic Traits and Quality of Potato
摘要
Abstract
Three types of foliar fertilizers,including PFS1(salt-tolerant phosphate-solubilizing bacterium-Pseudo-monas adaceae,108 CFU/mL),PFS2(PFS1+chitosan 1.7 g/L),and PFS3(PFS2+water-soluble macroelement fertilizer 1.5 g/L),on the basis of applying conventional base fertilizer(CF,including organic fertilizer 250 kg/ha+NPK compound fertilizer 500 kg/ha),were sprayed to investigate the effects of different foliar fertilizer combinations on agronomic traits and quality of potatoes('Xisen 6').Compared to the CF treatment,the PFS1 treatment did not significantly affect any potato indicators.However,the PFS2 treatment significantly increased starch content(22.3%)and soluble protein content(66.1%)in potato tubers.The PFS3 treatment did not demonstrate more pronounced advantages than PFS2 in agronomic traits or quality indicators.Therefore,the combination of salt-tolerant phosphate-solubilizing bacterium+chitosan(PFS2)is recommended as a foliar fertilizer regimen to enhance yield and improve quality in'Xisen 6'.关键词
