为掌握清香核桃在四川不同地区引种栽培的生物学特性,探索其生长习性和结果规律,开展清香核桃在四川的引种观察与栽培技术研究。通过3年连续观察和综合分析,结果表明:(1)清香核桃在四川的适应性较强,以在海拔400~1 800m的阳性平地、缓坡栽植为宜。(2)树势健壮,树体较大,幼树时生长较旺盛,枝条粗壮,侧芽萌芽率较低,成枝力较强。结果以顶生混合花芽为主,且单果、二果较多,果枝率偏低,丰产性表现一般。(3)该品种在配置适合当地物候期的授粉树、加强整形修剪、提高栽培管理技术的前提下,可适当扩大栽培面积与推广。
In order to master the biological characteristics of the introduction and cultivation of fragrant walnut in different areas in Sichuan, to explore its growth habits and the results of the law, to carry out the introduction of fragrant walnut in Sichuan and cultivation techniques. Through 3 years of continuous observation and comprehensive analysis, the results showed that: (1) Fragrant walnut is more adaptable in Sichuan, and it is suitable for planting on gentle flat land with positive elevation of 400 ~ 1800m. (2) The tree vigor is robust, the tree body is larger, the young tree grows more vigorous, the branches are thick, the buds of the lateral buds are lower, and the branching force is stronger. The results of the top mixed flower buds dominated, and more fruit, two fruit, fruiting branches rate is low, high yield performance in general. (3) Under the precondition that the species is suitable for the pollination tree suitable for the local phenophase, strengthening the shaping and pruning, and improving the cultivation and management techniques, the cultivation area and promotion may be appropriately expanded.
