摘　　要：对2015年栽植的早酥红梨树进行垄栽、平栽、沟栽3种栽植模式下植株生长与结果的研究。结果表明,2020-2021年度间,垄栽、平栽、沟栽的植株主干粗度年均增长量分别是14.39、11.54、10.21 mm;主枝粗度年均增长量分别是2.32、1.71、0.88 mm;植株外围营养枝年生长量分别是83、77、56 cm。均为垄栽的最大,平栽的次之,沟栽的最小,三者之间差异显著。平均单果重分别是274.5、243.5、215.6 g,垄栽的最大,三者之间差异显著。果实的可溶性固形物含量在12.5%~12.6%之间,差异不明显;果形指数分别是1.19、1.13、1.08,垄栽的最大,果形更接近长圆柱形。单株产量分别为24.6、21.2、17.1 kg,垄栽的最大,三者之间差异显著。灌水后垄栽的无积水,根部环境条件优于平栽和沟栽。The plant growth and yield of Zaosuhong pear planted in 2015 were studied under three planting modes:ridge planting,flat planting and ditch planting.The results showed that from 2020 to 2021,the average annual growth of trunk diameter of ridge,flat and ditch planting plants was 14.39,11.54 and 10.21 mm respectively;The average annual growth of main branch diameter was 2.32,1.71 and 0.88 mm respectively;The annual growth of vegetative branches around the plant was 83,77 and 56 cm respectively.The ridge planting was the largest,the flat planting was the second,and the ditch planting was the smallest.The average single fruit weight was 274.5,243.5 and 215.6 g,respectively.The ridge planting was the largest,and the difference among the three was significant.The soluble solid contents of fruit was between 12.5%and 12.6%,with little difference;The fruit shape index was 1.19,1.13 and 1.08,respectively.The ridge planting was the largest,and the fruit shape was closer to the long cylindrical shape.The yield per plant was 24.6,21.2 and 17.1 kg,respectively,and the ridge planting was the largest,with significant difference among the three.After irrigation,there was no water accumulation in ridge planting,and the root environmental conditions were better than flat planting and ditch planting.
