Effects of Different Soil Types on Growth and Photosynthetic Characteristics of Corylus heterophylla ×Corylus avellana
摘要
Abstract
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.关键词
