湖南新化不同海拔梯度下黑籽花生的生长及产量分析

Growth And Yield Analysis of Black-Seeded Peanut(Arachis Hypogaea, L.) At Different Altitude Gradients in Xinhua, Hunan Province

海拔作为一个重要的生态因子,其变化会对气候环境、生态因子、作物生产等产生一定的影响。为探讨不同海拔梯度下(360、430和500m)花生的生长和产量差异,采用大区对比试验对湘中地区油茶林套种的黑籽花生进行了比较。结果表明:随着海拔的升高,黑籽花生的主茎生长量、单株分枝数量和秕果数明显增加,单株结果数、饱果数、小区饱果、小区籽仁产量和经济效益明显下降。由结果可知,低海拔有利于黑籽花生的生产。

Altitude is an important ecological factor,and its changes will have a certain impact on climate environment,ecological factors,crop production and so on.In order to investigate the difference of growth and yield of peanut under different altitude gradients(360,430 and 500 m),a large-scale comparative experiment was conducted to compare the black-seeded peanut interplanted in camellia oleifera forest in central Hunan.The results showed that with the increase of altitude,the growth of main stem,the number of branches per plant and the number of unripe fruits of black-seeded peanut increased significantly,while the number of fruits per plant,full fruits per plot,full fruits per plot,seed yield and economic benefits of small plot decreased significantly.It can be seen that low altitude is conducive to the production of black-seeded peanuts.
