采用间伐降密、品种优化、整形修剪、水肥管理、花果管理、病虫害防治等措施,对7~9 a 生核桃低产园进行改造试验,研究不同措施对核桃园的影响。结果表明：不同措施对促进核桃园丰产的影响和作用不同,但联系紧密、相互促进,形成完善的改造系统。改造试验后,效果达到最优,产量由改造前的150 kg?hm－2上升到1500 kg?hm－2,增产1350 kg?hm－2,增产率达900％。
採用間伐降密、品種優化、整形脩剪、水肥管理、花果管理、病蟲害防治等措施,對7~9 a 生覈桃低產園進行改造試驗,研究不同措施對覈桃園的影響。結果錶明：不同措施對促進覈桃園豐產的影響和作用不同,但聯繫緊密、相互促進,形成完善的改造繫統。改造試驗後,效果達到最優,產量由改造前的150 kg?hm－2上升到1500 kg?hm－2,增產1350 kg?hm－2,增產率達900％。
채용간벌강밀、품충우화、정형수전、수비관리、화과관리、병충해방치등조시,대7~9 a 생핵도저산완진행개조시험,연구불동조시대핵도완적영향。결과표명：불동조시대촉진핵도완봉산적영향화작용불동,단련계긴밀、상호촉진,형성완선적개조계통。개조시험후,효과체도최우,산량유개조전적150 kg?hm－2상승도1500 kg?hm－2,증산1350 kg?hm－2,증산솔체900％。
Taking the measures of thinning and decreasing density,optimizing variety,training and pruning,fertilizer and water management,flower and fruit management,disease and pest control and so on to test how to improve 7 ~ 9 years-old Juglans regia of low-yield orchard,we studied the effects of different measures on the orchard.The results showed that different measures had different effect on improving the yield of Juglans regia ,but they were closely linked, mutual promotion and forming a perfect transformation management system.After improvemental test,the effect ar-chived the best,and the output was increased from 1 50 kg?hm-2 to 1 500 kg?hm-2 ,1 350 kg?hm-2 was increased and the increasing rate of the yield was 900%.
