摘要
通过日光温室小区试验研究了连作条件下丰香、全明星和土特拉等九种不同品种草莓的生长发育状况及根部病害发生状况。结果表明:与熏蒸对照相比,土特拉草莓连作土壤中定植成活率高,平均单株草莓根数、根系和茎叶干重下降少,叶面积指数较大,花蕾数较多,根茎较粗,物候期相对稳定,果实产量高、品质变化小,根部病害发生轻,抗(耐)连作障碍能力最强。全明星连作土壤定植成活率低,平均单株生物量降低最显著,收获期绝产,物候期变化大,根部病情指数高达83.4,抗(耐)连作障碍能力最弱,其次是丰香和童子一号。
The growth,development and root disease of nine kinds of different strawberry cultivars from continuous cropping,including Tudla,Toyonoka,All-star and so on,were studied though greenhouse trail. The results showed that the resistance of Tudla to continuous cropping obstacle was stronger than others＇. Comparing to the control,it was more suitable that Tudla was planted in continuous cropping soil because the survival rate and the yield were higher,the average dry weight of per plant was weightier,the stem diameter was thicker,the number of bud and leaf area index were bigger,the phonological phase and the quality were more stable respectively and the root disease was less serious. The biomass of All-star reduced more obviously with the lower survival rate,the highest index of root disease by 83.4 and there was no yield at harvest date. The resistance of All-star was the weakest flowed by Toyonoka and Tongzi yihao.
