| Abstract: |
| Effects of different irrigation low limits of alternate partial root-zone drip irrigation under plastic film on some physiological indexes,yield and quality and water use efficiency of muskmelon were studied,taking conventional drip irrigation as comparison.The results showed: free water/binding water of the all treatments of alternate partial root-zone drip irrigation less than conventional drip irrigation,and contents of chlorophyll,soluble protein and malondialdehyde(MDA) is higher than conventional drip irrigation,the treatments with low limits of alternate partial root-zone drip irrigation of 85% and 75% field water capacity saved water by 30.33% and 34.98% respectively,and water use efficiency increased by 40.32% and 47.11% respectively,yield only decreased by 2.71% and 4.34%. |
