中国低效苹果园改造现状、效果及建议

Situation,Effects and Recommendation of Inefficient Orchard Transformation

通过调查分析结果表明:果园间伐、树形改良是普遍采用和推广的低效苹果园改造技术;显著提高优果率、增加果园的单位面积纯收入,以及减缓轮纹病、腐烂病是低效苹果园改造的主要效果;果农接受速度慢、改造技术复杂果农掌握难度大,以及改造的后续保障措施不到位、配套集成技术缺乏等,是低效苹果园改造过程中存在的主要问题。因此,提出要循序渐进推进低效苹果园改造;创新技术指导形式,增强技术推广力量;完善改造后续保障措施,注重采用配套集成技术等建议。

This paper shows that intermediate cuttings and immprovement tree technology was been widely used and promoted in inefficient orchard renovation. The rate of excellent fruit significantly increased,net income per unit area of orchard increased,ring rot slowing was the main effect of the inefficient orchard renovation. Slowing growers accepted,complex transformation technology and lack of supporting integration technology was main problems existed in the process of inefficient orchard transformation. The article concludes with such recommendations as implementate the inefficient orchard transformation gradually,innovate forms of technical guidance to enhance the power of technology promotion,perfect follow-up safeguards transformation and focusing on the adoption of supporting integration technology.
