草莓是经济价值较高的小浆果 ,近几年来在国内发展很快 ,目前栽培面积已超过８０万亩 ,其中大部分为保护地栽培。由于草莓无性繁殖的特点及生产上的连作 ,目前国内生产用草莓苗几乎全部感染有病毒。病毒导致草莓植株衰弱、果实变小、品质变劣 ,繁殖能力降低 ,总体产量下降３０% Strawberries are small berries with high economic value. In recent years, they have developed rapidly in China. At present, the cultivated area has exceeded 800,000 mu, most of which are cultivated in protected areas. Due to the characteristics of asexual reproduction of strawberry and continuous production, the domestic production of strawberry seedlings is almost completely infected with viruses. The virus causes the strawberry plant to be weakened, the fruit becomes smaller, the quality deteriorates, the reproductive ability decreases, the overall yield drops 30%
