摘要
为了确定平欧杂种榛最适合生长的土壤类型,促进其高品质生产,研究不同类型的土壤对平欧杂种榛生长发育、叶片生长和光合特性的影响。结果表明,(1)砾质壤土栽培条件下,平欧杂种榛株高、新梢长度和新梢基径生长量比黏壤土和砂质壤土增加141.05%和187.40%、172.34%和139.00%、157.00%和123.48%,砾质壤土栽植的平欧杂种榛叶面积显著大于黏壤土和砂质壤土,分别增加101.13%、74.05%。净光合速率与土壤铵态氮和pH呈显著正相关,与交换性钙、交换性镁呈显著负相关;可见土壤pH为影响其光合的重要土壤因子,土壤交换性镁为限制因子。(2)根据熵权-TOPSIS综合性评价所得到的贴近度结果,砾质壤土为最优的平欧杂种榛种植土壤。综上,在3种土壤类型中,砾质壤土栽培最有利于平欧杂种榛幼树生长和叶片的发育,有利于对光能的吸收利用和提高叶片光合能力,其次为砂质壤土。
In order to determine the most suitable soil type for the growth of Corylus heterophylla×Corylus avellana promote its high quality production,the effects of different types of soil on the growth and development,leaf growth and photosynthetic characteristics of C.heterophylla×C.avellana were studied.The results showed that:(1)Under the condition of gravelly loam cultivation,the plant height,shoot length and shoot base diameter of C.heterophylla×C.avellana increased by 141.05%and 187.40%,172.34%and 139.00%,157.00%and 123.48%,respectively,compared with those of clay loam and sandy loam.The leaf area of C.heterophylla×C.avellana planted in gravelly loam was significantly larger than that in clay loam and sandy loam,which increased by 101.13%and 74.05%,respectively.The net photosynthetic rate was significantly positively correlated with soil ammonium nitrogen and pH,and significantly negatively correlated with exchangeable calcium and exchangeable magnesium.It can be seen that soil pH is an important soil factor affecting its photosynthesis,and soil exchangeable magnesium is a limiting factor.(2)According to the entropy weight-TOPSIS comprehensive evaluation of the closeness of the results obtained,the gravel loam is the best Ping-European hybrid hazelnut planting soil.In summary,among the three soil types,gravel loam cultivation is most conducive to the growth and leaf development of C.heterophylla×C.avellana saplings,which is conducive to the absorption and utilization of light energy and the improvement of leaf photosynthetic capacity,followed by sandy loam.
