新疆核桃具有颗粒大、薄壳、早熟等特性。车河地区林科所于1966年开始引种,经过几年来的精心培育,现有180亩新疆核桃,长势良好。6年生树平均高3.34米,平均冠幅2.82米,平均地径9.18厘米。最优株树高4.8米,冠幅4.55米,地径13.3厘米。1969年开始结果,至1972年已有40％的植株开花,有21株结果,总产果269个,单株最高产果95个。1970年培育的子代茁壮成长,1973年已高达1.3米,地径2.4厘米。1972年用枫杨作砧木,新疆核桃作接穗,嫁接也获得基本成功。新疆核桃南移成功的要点是: 1.种子处理。用温水浸种5天,然后取出,在室内用湿沙单层进行种子催芽。
Xinjiang walnut with large particles, thin shells, precocious characteristics. Chahe area Linke was introduced in 1966, after years of careful cultivation, the existing 180 acres of Xinjiang walnut, growing well. The 6-year-old tree averaged 3.34 meters high, with an average crown width of 2.82 meters and an average diameter of 9.18 centimeters. The best tree height of 4.8 meters, crown 4.55 meters, diameter 13.3 cm. The results began in 1969, to 1972, 40% of the plants have flowering, 21 results, the total fruit 269, the highest yield of 95 per plant. The children born in 1970 thrived, reaching a height of 1.3 meters and a diameter of 2.4 centimeters in 1973. 1972 with Feng Yang as rootstock, Xinjiang walnut scion, grafting also obtained basic success. Xinjiang walnut south move the main points are: 1. Seed treatment. Soaked with warm water for 5 days, and then removed, indoors with wet sand single seed germination.
