以干旱区梨为研究对象,进行了单因素试验和水肥耦合试验。梨树生长对水的反应,氮,为水肥高效管理提供理论依据。其中,单因素试验集水,氮,和磷作为三个因素,设置了五个级别。筛选出W3,W4,N3,N4,P3和P4促进植物养分吸收和果实品质。在水肥耦合试验中设置了八个处理:处理1(T1,W3N3P3),治疗2(T2,W3N3P4),治疗3(T3,W3N4P3),治疗4(T4,W3N4P4),治疗5(T5,W4N3P3),治疗6(T6,W4N3P4),治疗7(T7,W4N4P3),和治疗8(T8,W4N4P4)。结果表明,T1、T2、T3、T4处理的叶面积指数在成熟期显著高于其他处理。产量,单果重量,T3处理下初生果实率最高。果实品质的灰色关联度分析表明,T3处理各果实品质指标的关联度和排序最高,表明T3处理具有最高的果实品质。产量模型表明,灌溉量为6510.06m3hm-2,氮肥为337.5kgNhm-2,磷肥为262.5kgPhm-2,产量最好。对梨树生长和果实品质的详细调查表明,T3处理具有最佳的果实生长发育性能,梨果实品质最好。
Considering the pear in the arid region as the research object, single-factor testing and water-fertilizer coupling testing were conducted. The response of pear tree growth to water, nitrogen, and phosphorus was explored and provided a theoretical basis for efficient water and fertilizer management. Among them, the single-factor test set water, nitrogen, and phosphorus as the three factors, and five levels were set. Screening out W3, W4, N3, N4, P3, and P4 promoted plant nutrient uptake and fruit quality. Eight treatments were set up in the water and fertilizer coupling test: Treatment 1 (T1, W3N3P3), Treatment 2 (T2, W3N3P4), Treatment 3 (T3, W3N4P3), Treatment 4 (T4, W3N4P4), Treatment 5 (T5, W4N3P3), Treatment 6 (T6, W4N3P4), Treatment 7 (T7, W4N4P3), and Treatment 8 (T8, W4N4P4). The results showed that the leaf area index of the T1, T2, T3, and T4 treatments was significantly higher than that of the other treatments at maturity. The yield, single fruit weight, and primary fruit rate were the highest under T3 treatment. The gray correlation degree analysis of fruit quality showed that the T3 treatment had the highest degree of correlation and ranking of each fruit quality index, indicating that the T3 treatment had the highest fruit quality. The yield model showed that irrigation with 6510.06 m3 hm-2, nitrogen fertilizer with 337.5 kg N hm-2, and phosphate fertilizer with 262.5 kg P hm-2 had the best yield. A detailed investigation of pear tree growth and fruit quality showed that the T3 treatment had the best fruit growth and development performance, and the pear fruit quality was the best.
