| Abstract/Contents: | "Nutrient management is a significant measure to improve crop yield in modern agriculture. In order to find out the effect of fertilization on Ryegrass (Lolium multiflorum L.) physiology and yield relating to cold temperatures,a field experiment was conducted including five fertilization treatments: NPK, NP, NK, PK and CK (no fertilization). We tested leaf physiological indicators such as chlorophyll content, net photosynthetic rate, POD activities and MDA content during winter stage and harvested the grass yield. The result showed that nitrogen and phosphorus fertilizer could significantly increase the chlorophyll content of ryegrass (P<0.05), whereas potassium fertilizer did little. Nitrogen increased net photosynthetic rate in ryegrass significantly higher than phosphorus and potassium. Results also showed that the order of fertilizer effects on WUE of ryegrass was N>P>K. Content of chlorophyll, net photosynthetic rate and WUE showed as NPK>NP>NK>CK=PK; Transpiration rate decreased significantly when applying nitrogen or phosphorus fertilizer. The general trend was NPK=NPCK=PK while MDA content was completely opposite. Nitrogen, phosphorus and potassium application increased the ryegrass yield by 273.7%, 73.2% and 22.4% respectively. Results indicate that reasonable fertilization can adjust cold resistance indicators which promote ryegrass yield." |
