在江苏南京的气候、土壤条件下,桃树根系全年都能生长,具有一定节奏,呈双峰模式。第一个峰出现在春季,呈尖峰状,生长量占全年的60%~66%;第二个峰出现在秋季,呈尖峰状或波浪状,生长量占全年的10%~200%。新根的分枝一般有1~2次,产生2~3次根的数量很少。断根可促进分枝生长,分枝可达3次,数量约占新根量的50%。单根延长生长的速率,平均最高值为42.9mm/周,绝对最高值达70.0mm/周,均出现在春季生长高峰期。单根的寿命,长的可达1年左右,短的仅1周左右。
In Nanjing, Jiangsu climate, soil conditions, the peach tree roots can grow throughout the year, with a certain tempo, a bimodal pattern. The first peak appeared in spring with a spike shape, accounting for 60% ~ 66% of the annual growth. The second peak appeared in autumn with a spike or wavy shape, accounting for 10% ~ 200% . The roots of new roots are generally 1 to 2 times, producing 2 to 3 times the number of small roots. Broken roots can promote the growth of branches, branching up to 3 times, the amount of about 50% of the amount of new roots. The rate of single root elongation growth was 42.9 mm / week on average with the highest absolute value of 70.0 mm / week, all of which appeared in the peak of spring growth. A single root life, up to 1 year long, short only about 1 week.
