2个核桃新品种物候期及结实丰产性研究

Phenophase & Seed-Bearing Yield for Two New Varieties of Juglans regia

文章主要介绍了朝核1号、朝核2号核桃新品种的物候期,对二者在区域试验中的丰产性表现进行了研究,结果表明:在株行距4m×5m的果园内,朝核1号比对照系50610系、礼品2号和11001系分别增产62.66%、16.29%、36.70%;"朝核2号"比各对照系分别增产63.92%、17.19%、37.77%。在株行距5m×6m的果园内,朝核1号比对照系50610系、礼品1号和50410系增产46.26%、32.63%、32.63%;朝核2号比各对照系分别增产46.73%、33.05%和33.05%。朝核1号和朝核2号产量及结实稳定性明显优于用作对照的本地区几个常见栽植品种。矮化密植是获得较高产量的有效途径。

The phenophase of new walnut varieties(Juglans regia ‘Chaohe 1',Juglans regia ‘Chaohe 2')were introduced;the high yield of Juglans regia ‘Chaohe 1'&Juglans regia ‘Chaohe 2'in the regional trials was studied.Result shows that:in the orchard with the space between plants and between rows being 4m ×5m,Juglans regia‘Chaohe 1'increase by 62.66%,16.29% &36.70%than the CK(50610series,‘Lipin 2'&11001series), respectively;Juglans regia ‘Chaohe 2'increase by 63.92%,17.19% &37.77% respectively than the CK.In the orchard with the space between plants and between rows being 5 m × 6 m,Juglans regia ‘Chaohe 1'increase 46.26%,32.63% &32.63%than the CK(50610series,‘Lipin 1',50410series);Juglans regia ‘Chaohe 2'increase by 46.73%,33.05% &33.05%respectively than the CK.Yield &seed-bearing stability of Juglans regia ‘Chaohe 1'&Juglans regia ‘Chaohe 2'are optimal than several common planted varieties which were used as a control in this region.Dwarfing close-planting is one of the effective ways to get a higher yield.
