树势对巴旦杏新梢生长与开花坐果的影响

Effect of tree vigors on shoot growth and blooming Fruit-bearing in Almond

验以"鹰嘴"巴旦杏为调查对象,对强旺、中庸和衰弱三种树体营养类型的树,分别进行了自然落果率、枝梢营养状况和不同树体营养情况的调查研究。通过调查分析得出:3种不同树体类型的巴旦杏落果率高低顺序为强、弱、中,且中庸树与强旺树差异显著;春梢的生长量顺序为:中庸树>衰弱树>强旺树,且中庸树与强旺树有极显著差异,秋梢的生长量差异均不显著;中庸树体类型在保持一定结果枝、花芽比例,进行合理的肥水管理,可以使坐果率得到一定的提高。

The investigation obtains the order of 3 kinds of different tree types： fruit-falling rate of Yingzui almond is the mean tree, weak force tree, strong force tree, also the difference of the mean tree and strong force tree is remarkable. The order of the growth of spring shoot is： mean tree 〉 weak force tree 〉 strong force tree, and the difference between mean tree and strong force tree is extremely remarkable,but the difference of the growth of autumn shoot is not remarkable. The mean tree to maintain a certain outcome of the branch, the proportion of flower buds, rational management of fertilizer, can be a certain fruit-setting rate increase.
