| 摘 要： | 为选出适应黄土丘陵区栽培的核桃砧木,以交城县为试点,选择晋RS-1系、晋RS-2系、晋RS-3系、185、Tu-lare、Ford、Seer、Chico、Sexton、Livemore、Gillet、黑核桃等12个国内外砧木品种,通过调查种子出苗率、苗高和地径的生长量、抽梢率、抗病虫性等指标,对其品种特性展开研究。结果表明,出苗率表现为晋RS-1系(89%)>晋RS-3系(75%)>晋RS-2系(73%);地径苗高生长量为晋RS-3系>晋RS-1系>晋RS-2系;苗高生长量为晋RS-3系>晋RS-1系>晋RS-2系;抽梢情况表现为晋RS-3系和晋RS-1系最轻;抗病虫性为晋RS-3系>晋RS-1系>晋RS-2系。因此,在立地类型与交城县相近的黄土丘陵区,适宜的砧木品种为晋RS-3系、晋RS-1系、晋RS-2系。

| Abstract: | In order to select the walnut rootstock that could fit loess hilly area,emergence rate,height,ground diameter,sprouting rate and resistance to disease of 12 varieties of Jin RS-1,Jin RS-2,Jin RS-3,185,Tulare,Ford,Seer,Chico,Sexton,Livemore,Gillet,J.hindsii were investigated in Jiaocheng county.The results showed that the order was Jin RS-1(89%) > Jin RS-3(73%)> Jin RS-2(75%) for emergence rate;Jin RS-3> Jin RS-1> Jin RS-2 for height and ground diameter;Jin RS-3 > Jin RS-1 > Jin RS-2 for resistance to disease and pest;Jin RS-3 and Jin RS-1 were the best in their sprouting characteristic.The suitable varieties were Jin RS-3,Jin RS-1and Jin RS-2,and other foreign varietiess did not adapt to the hilly area of the Loess plateau. |
