摘要
[目的]人为控制其最佳上市时间,从而产生更大的经济效益。[方法]对采用不同方式处理后的大棚草莓进行对比试验,观测其品质和产量发生的变化。[结果]经过遮阳处理的大棚,气温低、日照少、光照强度差,因而草莓花芽分化早而快;而未进行遮阳处理的大棚因其棚内气温高、光照强,较经处理的大棚草莓分化日数平均多6 d。草莓在开花期,应当提前加温、加光处理,并使棚内温度保持在20℃以上,湿度应适当降低,最好能控制在60%以下。大棚草莓在果实膨大期如果环境温度高,则小果多,所以此期应通过通风、棚外喷水等人工调控技术适当降低棚内温度。大棚草莓灰霉病发病率与棚内空气相对湿度呈显著的正相关,白粉病发病率与棚内温度呈正相关。[结论]确定了延长草莓果实膨大期,提高大果比例,促进增产增收的方法。
[ Objective ] The study aimed to control the best time on market, creating greater economic benefits. [ Method ] Through the use of different ways of dealing with the greenhouse strawberries comparison tests, the changes of quality and yield were observed. [ Result ] The greenhouse treated with shade had low temperatures, less sunshine, the light intensity difference, as a result strawberry flower bud differentiation was early and fast. But greenhouse untreated with shade had high temperatures, strong light, and the number of days on average differenti- ation was more 6 d than the greenhouse treated with shade. During the flowering stage, strawberry should be added heat and light processing in advance, and kept temperature above 20 ℃, the humidity degree should be appropriately reduced, and controlled less 60%. If the environmental temperature was high during the fruit expanding process, the small fruit number was many. So people should reduce the temperature during the fruit expanding process through different control technology. The Botrytis cinerea incidence of greenhouse strawberry had significant positive correlation with the greenhouse relative humidity, and the powdery mildew incidence of greenhouse strawberry had correlation with the greenhouse temperature. [ Conclusion ] The method of extending the fruit expanding process, raising the proportion of fruit, increasing the incomes was confirmed.
