摘要
草莓高架栽培因劳动强度小、果实品质高等特点受到生产者的推崇。为了探讨日光温室高架栽培草莓的耗水规律,明确草莓耗水量与环境气象因子之间的相关性,采用水量平衡法开展了日光温室高架栽培草莓耗水规律的研究。结果表明,草莓整个生育期耗水量呈U型变化,在花芽分化期、越冬期和开花结果期日均耗水量分别为71.9、58.1、74.8 mL/(株·d)。试验还得到了草莓日均耗水量和累积光辐射能、日均温度和日均相对空气湿度之间的多元线性模型:ET=0.288X+0.333Y-0.096Z,为指导草莓灌溉、实现灌溉的自动化、智能化管理奠定了理论基础。
Elevated strawberry cultivation was promoted for its advantages of reducing labor intensity and increasing fruit quality. In order to study the water consumption law of strawberry in solar greenhouse and to clarify the correlation between water consumption of strawberry and environmental meteorological factors, this paper studied the law of water consumption by water balance method. The results showed that the water consumption of strawberry during the whole growth period showed a U-shaped variation, and the average daily water consumption of strawberry was 71.9 mL/(plant·day), 58.1 mL/(plant·day), and 74.8 mL/(plant·day) during flower bud differentiation, overwintering period and flowering and fruiting period, respectively. The multivariate linear model was obtained between the daily water consumption and the accumulated light radiation energy of strawberry, the average daily temperature and the average daily relative air humidity: ET =0.288 X +0.333 Y-0.096 Z, which laid a theoretical foundation for the automation and intelligent management of irrigation.
