【摘要】 不同的草莓栽培形式需要不同的草莓品种,1个草莓品种适宜哪种栽培形式是由其本身的需冷量决定的,明确草莓的需冷量是成功栽培草莓的1个关键因素。以河北省农林科学院石家庄果树研究所选育的优良草莓新品系458-2为试材,在冷库(库温2℃)中存放不同的时间,然后放入到日光温室中,根据草莓的生长情况分析打破休眠所需的低温需求量,确定其最适的栽培形式,可以使新品系发挥最大的生产潜力,实现良种良法。结果表明:458-2新品系的需冷量为300 h左右,属中早熟品种,适宜保护地半促成栽培及露地栽培。更多还原

【Abstract】 Different cultivars of Strawberry demand different cultivation modes,the latter are decided mainly by strawberry’s chilling requirement.Taking new strawberry cultivar 458-2 as experimental material,which was bred by Shijiazhuang Institute of Pomology,effects of different cold storage(2 ℃) time before transplanting into the greenhouse were analyzed.According to the growth of strawberry,the demand of low temperature in order to break dormancy was determined.The results showed that chilling requirement of cultivar 458-2 was 300 h.By adopting the optimum cultivation mode,new cultivar could express its production potential.The new strawberry cultivar 458-2,with mid-early maturity,suited for protected field semi-forcing cultivation and open cultivation.更多还原
