摘要
笔者对辽榛7号的开花习性、生长结果习性、丰产性、抗逆性等进行田间观察和经济性状对比试验,结果表明,辽榛7号的雌花、雄花一般在3月下旬至4月上旬开放,维持10 d^13 d左右;在4月上旬芽开始萌动。辽榛7号在山西省晋北、晋西北风沙和高寒地区及吕梁山、太行山海拔较高区域均能正常生长结果,果实成熟时间较达维早10 d左右;平均单株产量略高于对照品种达维。辽榛7号和对照品种达维抽条率、抽条长度、抽梢比例相差不大,虽有少量抽梢,但不影响正常生长结实。辽榛7号榛子果大壳薄,坚果3径均值17.23 nnn,单果重2.65 g,果壳厚度1.4 mm,商品价值高。
Field observation and comparative test of economic characters of Liaozhen No.7 such as flowering habit,growth and bearing habit,high yield and stress resistance were conducted.Results showed that the female and male flowers of Liaozhen No.7 opened from late March to early April and last for about 10?13 days.Its buds began to sprout in early April.Liaozhen No.7 could grow and bear normally in the windy sand and high cold areas in the north and northwest of Shanxi Province,and in the high altitude areas of Luliang Mountain and Taihang Mountain.The ripening time of the fruit was about 10 days earlier than that of Dawei.There was no significant difference between Liaozhen No.7 and Dawei in the sprout rate,sprout length and sprout ratio.It did not affect the normal growth and fruiting although there were a few shoots.Liaozhen No.7 had a large fruit and thin shell.The average diameter of nut was 17.23 mm,and the weight of single fruit was 2.65 g.The thickness of shell was 1.4 mm,and the commodity value was high.
