| 为充分发挥攀西地区光热资源优势，创新优化早熟桃配套栽培技术，本研究以攀西地区4个早熟桃品种为试材，研究了叶面喷施多效唑、夏季修剪以及不同栽植密度对早熟桃植株生长指标的影响。结果表明，叶面喷施多效唑显著抑制了桃树春梢生长，但提高了单株挂果量和冠层叶片温度；夏季修剪均促进了‘中农金辉’和油桃优系1181二次枝的萌发，但1181抽生的二次枝主要为短枝，而‘中农金辉’抽生的二次枝主要为长枝；当栽植密度增加时，‘中桃红玉’的多项植株生长指标和单株挂果量显著下降，而‘中桃紫玉’的各项生长指标未出现显著变化，但显著提高了距地面1.5m处叶片的SPAD值和氮含量，并显著降低了冠层叶片温度。本研究为研发攀西地区早熟桃控梢保果和合理密植技术提供了理论依据。 |

| The aim is to fully utilize the advantages of light and heat resources in Panxi region and innovate and optimize the cultivation techniques of early-maturing peach. Taking four varieties of early-maturing peaches in Panxi region as test materials, the effects of foliar spraying with paclobutrazol, summer pruning, and varying planting densities on the growth indexes of the peach plants were systematically studied. Spraying paclobutrazol significantly inhibited the growth of spring shoots of peach trees, but increased the number of fruits per plant and temperature of canopy leaves. Summer pruning promoted the germination of secondary branches of ' Zhongnongjinhui ' and 1181. However, the secondary branches of 1181 were mainly short branches, while the secondary branches of ' Zhongnongjinhui ' were mainly long branches. As the planting density increased, a number of plant growth indexes and fruit counts per plant of ' Zhongtaohongyu ' decreased significantly. In contrast, Zhongtaoziyu's growth indexes did not change significantly. However, the SPAD value and nitrogen content of leaves at 1.5 m above the ground were significantly increased, while the temperature of canopy leaves was significantly reduced. This study serves as an important theoretical basis for the development of supporting cultivation techniques aimed at controlling excessive growth, improving fruit retention, and facilitating rational dense planting of early-maturing peaches in the Panxi region. |
