昆明市核桃低产园改造技术研究

Study On Technology Of Renovation Of Low-Yield Walnut Garden In Kunming

以昆明市低产云新系列早实核桃园(种植8年和4年)和低产漾濞核桃园(种植12年)为研究对象,以未采取综合改造措施园区为参照,对比研究综合改造措施对核桃生长和产量的影响,为昆明市低产核桃园的经营管理提供技术支持。结果表明:(1)综合改造对低产云新系列早实核桃园(种植8年和4年)和低产漾濞核桃园(种植12年)的核桃生长、产量均有显著的提升效果;(2)综合改造技术对低产漾濞核桃园(种植12年)的效果最为显著,实施后亩产提高了70. 6%。在低产云新系列早实核桃园和低产漾濞核桃园的改造后,应配合持续的经营管理措施,以维持改造成效。扩大试验范围,形成技术标准并推广是下一步工作的重点。

Taking low-yielding Yunxin series Early-fruiting Walnut orchards( planted for 8 and 4 years) and low-yielding rippling walnut orchards( planted for 12 years) in Kunming as the research objects,and taking the park without comprehensive transformation measures as the reference,the effects of comprehensive transformation measures on the growth and yield of walnuts were studied comparatively,so as to improve the management of low-yielding walnut orchards in Kunming. For technical support. The results showed that:( 1) comprehensive transformation had significant effect on the growth and yield of early-bearing walnut orchards( 8 and 4 years of cultivation) and low-yielding walnut orchards( 12 years of cultivation);( 2) comprehensive transformation technology had the most significant effect on low-yielding walnut orchards( 12 years of cultivation),after implementation the yield per mu increased by 70. 6%. After the transformation of low-yielding Yunxin series Early-fruiting Walnut orchards and low-yielding rippling walnut orchards,continuous management measures should be taken to maintain the transformation effect. Expanding the test scope,forming technical standards and popularizing them are the key points of the next step.
