| Abstract: |
| 【Objective】To explore the influence of different factors of domestic reclaimed water irrigation on the yield and quality of alfalfa. 【Method】Through the three-factor three-level orthogonal test, using the analysis of variance and analysis of variance, etc., the order of the major and minor factors of different factors, significance, the influence trend of each factor and the optimal combination were studied. 【Result】The results showed that irrigation quotas had effects on alfalfa plant height, stem thickness, number of first branches, hay yield, crude fat, crude fiber, acid washing fiber, neutral washing fiber, relative feeding value, total nitrogen, total phosphorus, and total potassium The effect of water and calcium was significant (P <0.05); the quality of irrigation water had a significant effect on coarse ash. The comprehensive influence of irrigation quota, irrigation technology and irrigation water quality on the growth, yield and quality of alfalfa, the reference combination T8 (A3B2C1) is consistent with the optimal combination. The chromium was not detected in this treatment, and the lead was the highest, but the lead content was far less than the national standard.【Conclusion】 It is suggested that the reference design of the experimental area is that the irrigation quota is 240m3/hm2, the irrigation technology is underground drip irrigation, and the irrigation water quality is reclaimed water. |
