文冠果(Xanthoceras sorbifolia Bunge)是我国“三北”地区一个很有发展前途的油料树种。但由于它长期处于野生状态,类型混杂,单株间种子产量相差悬殊,单位面积产量很低。而且大面积人工栽培的历史尚短,所以至今还没有探索出完整的丰产栽培措施。为提高文冠果的产量,弄清其产量与有关技术措施的关系,我们对文冠果种子产量与优树利用、栽植密度、树形、结果枝类、修剪和施肥灌水等因子之间的关系,进行了初步研 Xanthoceras sorbifolia Bunge is a promising oilseed species in the “Three Norths” of China. However, due to its long-term status in the wild, the types of hybrids, there is a big difference between the seed yield per plant, yield per unit area is very low. And the history of large-scale artificial cultivation is still short, so far no full-bodied cultivation measures have been explored. In order to improve the yield of the plant and ascertain the relationship between the yield and the related technical measures, we analyzed the relationship between the seed yield of the plant and the optimal tree utilization, planting density, tree shape, fruiting branches, pruning and fertigation irrigation Relationship, conducted a preliminary study
