摘要
抗青一号为番茄砧木一代杂交种。该品种早中熟、耐寒性强、高抗青枯病。其与接穗易亲和、成活率高,嫁接后的番茄高抗青枯病等土传病害,抗逆性提高、不易衰老、产量增加、农药用量减少,且果实品质、商品性无不良影响。湖南省各示范点嫁接后均表现比对照红石串自根苗增产,增产幅度为50%～131.13%,平均产量3 800～4 500 kg/667m2,最高产量达5 000 kg/667m2,嫁接后增产效果十分显著,且嫁接对接穗品质影响不大。适宜在青枯病严重的番茄产区作嫁接番茄砧木品种,进行早春保护地或露地丰产栽培使用。
Kangqing No.1 is F1 hybrid of the tomato rootstock.This variety has characteristics of early middle maturity,strong cold resistance,high resistance to bacterial wilt,affinity with scion easy and high survival rate.The grafted tomato has high resistance to bacterial wilt and other soil-borne diseases,has the following characteristics：improving stress resistance,not easy to aging,high production,reduced pesticide dosage and fruit quality without adversely affecting the marketability.At each exemplary base in Hunan province,the yield of grafted tomato increased by 50%～131.13% compared with CK（Hongshichuan self-rooted）,the average yield was 57 000 ～67 500 kg/hm2,the maxium yield up to 75 000 kg/hm2,after graftin the stimulation effect was obvious and had little effect on fruit quality.Kangqing No.1 is a suitable rootstock variety for grafting tomato in tomato-producing areas with serious bacteria wilt,and suites for early spring protection or open high-yielding cultivation.
