摘要
为探明丘陵山地条件下四季蜜芒反季节栽培丰产稳产果园的树体结构相关指标以用于指导生产,以树龄为12年、行株距为4.0m×2.8m、连续4年平均产量30994.5 kg/hm^(2)的四季蜜芒反季节栽培丰产丘陵地形果园为调查对象,在果园的山顶、山腰、山脚各取样4株进行冠高、冠径、枝条数、枝粗、枝长、叶片数及叶片长度、宽度、厚度等方面调查与统计分析。结果表明:丰产稳产果园的植株树冠形状为自然圆头形,冠高2.88m,行向冠径3.30m,株向冠径3.11m,冠高率89.1%;株间交叉0.31m,行间空距0.70m,果园密株不密行;单株末级梢数239条,单枝长度20.08 cm、粗度0.853 cm;末级梢叶片数15.34片,最大叶片的长度、宽度、厚度分别是19.85 cm、6.51 cm、0.29mm。
To explore the tree structure index of high and stable yield orchards of anti-season Mangifera indica L.cv.SiJiMi under hilly and mountainous conditions for guiding production,a study was conducted on a high and stable yield orchard of anti-season M.indica L.cv.SiJiMi with 12-year-old trees,row and plant spacing of 4.0 m×2.8 m and an average yield of 30994.5 kg/hm^(2)for 4 consecutive years.Each four trees sampled from the hilltop,hillside and foot of the hill were surveyed and analyzed in terms of crown height,crown diameter,number of branches,length and di-ameter of branches,number of leaves,and length,width and thickness of leaves,etc.The results showed that the crown shape of plants in a high and stable yield orchard was natural-round-head shape,with a crown height of 2.88 m,a row-oriented crown diameter of 3.30 m,a plant-oriented crown diameter of 3.11 m,and a crown height rate of 89.1%;the cross between plants was 0.31 m and the space between rows was 0.70 m,with close plant spacing and no close row spacing;the num-ber of final tip per plant was 239,with a single branch length of 20.08 cm and a diameter of 0.853 cm;the number of leaves of final tip was 15.34,and the length,width and thickness of the biggest leaf were 19.85cm,6.51cm and 0.29mm,respectively.
