| 摘 要： | 以红美人柑橘的需肥特性为基础,研究以沼液和腐烂柑橘发酵净化液为基础原料配制而成的有机液肥滴灌对红美人柑橘园土壤环境、柑橘产量、品质和经济效益的影响。试验设4个处理:CK,不施肥;F1,农民习惯施肥(复合肥撒施, N 480 kg·hm-2,P2O5 480 kg·hm-2,K2O 480 kg·hm-2);F2,纯化肥配方肥滴灌施肥(N 480 kg·hm-2,P2O5 180 kg·hm-2,K2O 540 kg·hm-2);F3,有机液肥滴灌施肥(N 400 kg·hm-2,P2O5 120 kg·hm-2,K2O 380 kg·hm-2)。结果显示:不同施肥管理均可以提高土壤肥力,增加柑橘产量和经济效益,但易导致土壤酸化,有机质含量降低。与F1和F2处理相比,F3处理能提高土壤pH值,减轻土壤酸化,增加经济效益6.73%~25.39%,对果实品质无明显不利影响。虽然滴灌施用有机液肥可以减少化学肥料投入量,提高土壤肥力,减轻土壤酸化,满足红美人柑橘生长需求,并带来较高的产量和经济效益,但生产上仍应补施有机肥。 |

| Abstract: | Based on the nutritional requirement, the organic liquid fertilizer made from biogas, rotting citrus and chemical fertilizers, was drip fertigated to test its effect on soil fertility, fruit yield and economic income of citrus cv. beni madonna. Four treatments were set: CK, no fertilization; F1, traditional fertilization (spread application, N 480 kg·hm-2, P2O5 480 kg·hm-2, K2O 480 kg·hm-2); F2, balanced chemical fertilization (N 480 kg·hm-2, P2O5 180 kg·hm-2, K2O 540 kg·hm-2, drip fertigation); F3, organic liquid fertilization (N 400 kg·hm-2, P2O5 120 kg·hm-2, K2O 380 kg·hm-2, drip fertigation). The results showed that fertilization could enhance soil fertility, increase citrus fruit yield and economic income, but would decrease soil pH and soil organic matter content. Compared with F1 and F2 treatments, it achieved higher soil pH, and increased economic income by 6.73%-25.39% under F3 treatment. Besides, there was no significant difference on fruit quality within treatments. Although drip fertigation with organic liquid fertilizer could reduce fertilizer input, improve soil fertility, elevate soil pH, and increase the fruit yield and economic income, addition of other organic fertilizers should be well considered. |
