摘要
桂西北地区长期以来种植泡核桃,然而对泡核桃种植的立地条件并未进行系统的调查分析。为了探寻最适于泡核桃生长的立地条件,从而为桂西北地区因地制宜发展核桃产业提供数据支撑,以广西壮族自治区凤山县为例,研究了海拔高度、坡度坡向、土壤类型、土壤质地等立地条件对泡核桃生长结实的影响情况。结果表明:泡核桃树的生长势随着海拔的升高而减弱,海拔高度对泡核桃产量的影响差异不显著;坡度与坡向对泡核桃树的生长势与产量均无显著影响;土壤类型对泡核桃树的生长势与产量的影响差异均显著。总体上讲,土壤质地对泡核桃树生长势与产量的影响差异均显著;种植在黄壤土上的泡核桃树其生长势与产量比种植在红壤土和砂壤土的都要好要高,种植在中壤土上的泡核桃树其生长势最好,种植在轻壤土的的泡核桃树其产量最高;土壤厚度对泡核桃产量的影响差异显著,种植于土层厚度为20~50cm和>50cm的土壤上的泡核桃树其产量均较高。
J. sigillata has been cultivated in northwest Guangxi for a long time. However, systematic investigation and analysis on planting site conditions were not carried out. In order to find out the most suitable site conditions for J. sigillata growth, and to provide some data supports for developing walnut production for adaption to local conditions in northwest Guangxi, this paper researched effects of elevation, slope direction, soil type and soil texture on J. sigillata growth and bearing in Fengshan County. The results showed that growth vigour of J. sigillata was decreased with elevation rising. Altitude had no significant effects on J. sigillata yield. Slope and aspect had no significant effect on growth vigour and yield of J. sigillata. Soil type had significant differences on growth vigour and yield of J. sigillata. As a whole, soil texture had significant effects on growth vigour and yield of J. sigillata. Growth vigour and yield of J. sigillata in yellow loam were better and higher than those in red loam and sandy loam. Growth vigour of J. sigillata in middle loam was the best, and yield in light loam was the highest. Soil thickness had significant effects on yield of J. sigillata, and yield of trees in loam at 20-50 cm and > 50 cm thickness was higher.
