Abstract:
Taking the fruit mulberry variety ‘Da 10’ as the experimental material,conventional irrigation and fertilization were used as the control, set two drip irrigation levels of 80% and 70% of conventional irrigation amount,and two fertilization levels of 80% and 60% of conventional fertilization amount to carry out drip irrigation water and fertilizer integration test.The changes in growth,yield and partial fertilizer productivity indicators of different dropper fertilization treatments,and comprehensive evaluation using entropy weight TOPSIS were studied,in order to provide reference for scientific irrigation and fertilization of facility mulberry cultivation.The results showed that there was no effect with different drip fertigation treatments on branch germination and leaf growth of fruit mulberry.Drip fertigation treatments T1 and T2 had higher fertilizer partial productivity，and could promote branch growth，increase fruit number，single fruit weight and yield per plant，and reduce fruit drop rate.The analysis of entropy weight TOPSIS method showed that the relative closeness of T1 treatment was the first，which was 0.805 4，followed by T2 treatment，and the relative closeness was 0.552 3.It was concluded that when the drip irrigation amount was 80% (3 200 m3?hm-2) and the fertilization amount was 60%-80%，the mulberry yield index and fertilizer utilization rate were high，which should be popularized and applied in production.
