运用组织培养手段,生产草莓无病毒试管苗,经过防蚜隔离繁育,应用于大面积生产,这是一项提高草莓产量和品质的突破性技术措施。有关资料表明。日本草莓主产区的奈良县,在使用组培脱毒苗后,草莓病毒复合感染率从原来的70%下降到8%,产量增加了1.6倍。日本爱知县一农户应用脱毒苗与高产栽培技术相搭配,使草莓产量上升到4000kg/666.7平方米。占美国草莓面积75%以上的加利福尼亚州,在草莓推广露地栽培、垄栽、滴灌等先进的 The use of tissue culture to produce strawberry virus-free in vitro test tube, after aphids isolated breeding, applied to large-scale production, which is a breakthrough to improve strawberry yield and quality technical measures. Relevant information shows. In Nara Prefecture, a major strawberry producing area in Japan, the combined infection rate of strawberry virus decreased from 70% to 8% and its yield increased by 1.6 times. Aichi Prefecture, Japan, a farmer application of virus-free seedlings and high-yield cultivation techniques match, the strawberry production rose to 4000kg / 666.7 square meters. California, accounting for more than 75% of strawberry area in the United States, promotes the open cultivation of strawberry, ridge planting, drip irrigation and other advanced
