泡核桃产业化生产中,普遍存在生长结果初期植株间延长枝交叉、树势失衡、枝条徒长现象。通过多年研究,摸索出了适当疏剪、喷施富氧钾肥、合理间作与覆盖、造伤及人工辅助授粉等早期丰产栽培技术,从而有效控制了树体营养生长,为后期丰产奠定了基础;技术实施第4年,干果产量达149.4kg/667m2,产值达4 500元/667m2。试验结果为提高泡核桃产业早期栽培效益及产业可持续发展提供了技术支撑。
Bubble walnut industrial production, the prevalence of early growth of plants growing branches to extend the cross, tree potential imbalance, leggy growth phenomenon. Through years of research, we have found out the early high yielding cultivation techniques such as proper pruning, fertilizing potassium-rich fertilizer, rational intercropping and covering, wounding and artificial pollination so as to effectively control the vegetative growth of tree and lay the foundation for the later yield. In the fourth year of technical implementation, the output of dried fruits reached 149.4kg / 667m2, with an output value of 4 500 yuan / 667m2. The experimental results provide technical support for improving the early cultivation efficiency of bubble walnut industry and the sustainable development of the industry.
