针对利川核桃发展的要求,通过对利川核桃主产区实地调查,发现品种良莠不齐、缺乏优良种苗繁育技术、栽培管理中技术水平低下、病虫害严重是利川发展核桃生产存在的主要问题。结合利川资源优势以及良好的干果生产栽培基础,提出了加强核桃品种选优、尽快推广核桃嫁接育苗技术以及适地适树、科学配置授粉树等相应的发展对策。积极发展核桃产业,也是充分发挥山区生态潜力、治理水土流失的重要措施之一。
According to the requirements of the development of walnut in Lichuan, the main problems in the development of walnut production in Lichuan were found through the field investigation of the main producing areas of Lichuan walnut, which found that there were both good and bad varieties, lack of excellent seedling breeding techniques, low technical level in cultivation and management, and serious pests and diseases. Combining with the advantages of Lichuan and the good foundation for the production and cultivation of dried fruits, some countermeasures were proposed to strengthen the selection of walnut varieties, popularize the technology of grafting and seedling propagation of walnut as soon as possible, and to adapt trees and scientifically configure pollination trees. To actively develop the walnut industry is also one of the important measures to give full play to the ecological potential in mountainous areas and control soil and water loss.
