摘要:
为探讨‘绿岭’核桃对光照的需求和适应性，设置了不同遮阴程度（80%、50%、30%），研究其对翌年‘绿岭’核桃树体生长发育的影响。结果表明：80%遮阴处理的一年生枝抽干长度和比例极显著大于其它处理和CK，分别为75 cm和37.5%；80%遮阴处理的主枝抽干长度及比例极显著大于其它处理和CK，分别为138 cm和72.42%；80%遮阴处理的主枝上结果枝抽干数量及比例极显著大于其它处理和CK，分别为每枝21.67条和91%；80%遮阴处理的结果枝抽干数量极显著大于其它处理和CK，每株达212条；80%遮阴处理的核桃叶片叶绿素含量极显著低于其它处理和CK；80%遮阴处理的叶面积指数极显著低于其它处理和CK，仅为2.34；80%遮阴处理的平均叶倾角极显著低于其它处理和CK，仅为40.23°；80%遮阴处理的无截取散射极显著高于其它处理和CK，达到0.17；80%遮阴处理的枝条含水量显著高于其它处理和CK，高达51.60%；80%遮阴处理枝条的可溶性糖、蔗糖和淀粉含量均显著低于其它处理和CK，仅为4.53%、2.07%和4.25%；80%遮阴处理的单株结果数量极显著低于其它处理和CK，每株仅为37.67个；80%遮阴处理的冠幅极显著低于其它处理和CK，仅为260.00 cm×323.33 cm；80%遮阴处理一年生枝的长度和粗度极显著大于其它处理和CK，达到241.12 cm和3.02 cm。
Abstract:
In order to study the needs and adaptability to sunlight of ‘Lyuling’ walnut,the effects of different degrees of shads (80%,50% and 30%) on the second year growth and development of ‘Lyuling’ walnut were studied.The results showed that,the elongation and proportion of dead annual branches in the 80% shading treatment were significantly higher than that of other treatments and CK,which were 75 cm and 37.5%；the elongation and proportion of dead main branches in the 80% shading treatment were significantly higher than that of other treatments and CK,which were 138 cm and 72.42%；the elongation and proportion of dead fruiting branches above main branch in the 80% shading treatment were significantly higher than that of other treatments and CK,which were 21.67 each branch and 91%；the number of dead fruiting branches in the 80% shading treatment were significantly higher than that of other treatments and CK,which was 212 each strain；the chlorophyll content of 80% shading treatment was significantly lower than that of other treatments and CK；the LAI of 80% shading treatment was significantly lower than that of other treatments and CK，which was only 2.34；the MTA of 80% shading treatment was significantly lower than that of other treatments and CK，which was only 40.23°；the DIFN of 80% shading treatment was significantly higher than that of other treatments and CK，which was 0.17；the water content of branch in the 80% shading treatment was significantly higher than that of other treatments and CK，which was 51.60%；the soluble sugar,sucrose and starch content of branch in the 80% shading treatment were significantly lower than that of other treatments and CK，which were only 4.53%,2.07% and 4.25%；the number of each plant of 80% shading treatment was significantly lower than that of other treatments and CK，which was only 37.67 each strain；the tree canopy width of 80% shading treatment was significantly lower than that of other treatments and CK,which was only 260.00 cm×323.33 cm；the annual branches elongation and diameter 80% shading treatment was significantly higher than that of other treatments and CK，which were 241.12 cm and 3.02 cm.
