摘要
榆林山地苹果绝大多数为“雨养农业”,为提升山地苹果标准化建园水平,缩短幼树待产周期,该试验以常规栽植为对照,研究“七个一”抗寒抗旱栽植技术对榆林山地苹果幼树栽植成活率、树体生长量及早果性的影响。结果表明,采用该技术,极大地提高了‘长富2’幼树栽植成活率,较常规栽植提高47.5%~51.1%;树体生长量显著增加,一年生‘长富2’株高、分枝数、干径、新梢长度分别较常规栽植增加57.35%~74.59%、110.0%~145.0%、60.00%~61.22%、90.02%~92.42%;早果丰产性明显提升,4年生‘长富2’结果株率较常规栽植增加45.6%~47.3%;6年生株产较常规栽植增加69.66%~80.00%。
Apples planted in the mountains of Yulin City have no irrigation conditions and mainly rely on rainwater watering.In order to improve the level of standardized apple garden construction in this region and shorten the growth cycle of young trees.In this experiment,“seven one”cold and drought planting techniques were applied to study the effect of this technology on apple saplings survival rate,tree growth and early fruit.The results showed that the survival rate of‘Changfu 2’was increased by 47.5%to 51.1%than the conventional planting.Compared with the routinely planted saplings,the height,the number of branches,trunk diameter and the length of‘Changfu 2’saplings growing for a year increased by 57.35%~74.59%,110.0%~145.0%,60.00%~61.22%,90.02%~92.42%;The early fruit and fertility of young trees using this technology have been improved.Compared with conventional planting,the number of apple trees growing after 4 years of growth increased by 45.6%~47.3%;the number of fruit trees growing for 6 years increased by 69.66%~80.00%.
