| Abstract: |
| 【Objective】The effects of water and fertilizer coupling on the growth and yield of day lily were studied. 【Method】This experiment took day lily as the research object, two factors experiments were set up to study the effects of water and fertilizer coupling on the growth and yield of day lily. 【Result】 Under the same drip amount, the yield of day lily was significantly different under different drip times, and the agronomic characters of day lily were the best under IV and V treatments, and the maximum yield was 5 983.96-6 000 kg/hm2. Under the same fertilization time and different fertilization rates, S-Ⅳ treatment and S-Ⅴ treatment showed the best agronomic characters such as height, number of flower buds and flower buds. 【Conclusion】 Daylily should be dripped 8-10 times during the whole growth period and fertilized with 525-600 kg/hm2. |
