美国草莓居世界之冠。据1984年统计,年产量为29.5万吨,占全世界草莓年产量150百吨的19.7%。其发展趋势是栽培面积下降,而单位面积产量和总产上升,这完全归功于培育高产新品种、改进栽培技术和应用无病毒苗的结果。为了开发我省草莓生产,1985年省两西指挥部从美国引进了四个草莓新品种,委托我所进行栽培试验,观察品种的生物学性状,选择适宜我省栽培的丰产、抗病 American strawberry ranks highest in the world. According to the statistics of 1984, the annual output is 295,000 tons, accounting for 19.7% of the annual output of strawberry of 150 tons in the world. The development trend is the decline of cultivated area, and the increase of yield per unit area and total output, which is entirely attributed to the cultivation of new varieties with high yield, improved cultivation techniques and application of virus-free seedlings. In order to develop strawberry production in our province, in 1985, two provincial headquarters of the province introduced four new strawberry varieties from the United States, entrusted me with cultivation experiments, observed the biological traits of the varieties, and selected the high yield and disease resistance suitable for cultivation in our province
