根据北方葡萄大多采用埋土越冬的特点,笔者经多年的试验和研究,结合甘肃农业大学齐与枢、王嘉长两位教授的指导,总结出适合北方埋土越冬地区葡萄的整形方式--双主蔓规则扇形。该整形技术植株形成后不留主干,从地面附近分两个主蔓,分别向斜上方生长或都向同一方向倾斜生长 According to the characteristics of northern grapes mostly used for embedding soil overwintering, after years of experiments and studies, combined with the guidance of two professors Qi Heshu and Wang Jiachang of Gansu Agricultural University, the author sums up the plastic methods suitable for the northern grapes Man rule fan-shaped.
