摘要
计算研究了枸杞全生育期及不同生长阶段气温、光照、降水、相对湿度、大风等因子对产量的影响,确定了各自的指标。结果表明,枸杞全生育期需要≥10℃积温为3450℃·d,日照1640h;不同生长阶段存在不同的相关气象因子,尤其夏果幼果期最敏感。枸杞在夏果幼果期不耐高温,受干热风影响严重,这是枸杞研究中迄今为止的一个新发现。
By analyzing statistic characters of meteorological data and historic yield data of Lycium barbarian L, The influence of yiled with different vactors is studied such as temperature, radiation, precipitation, relative humidity and wind speed in whole growing season or in different terms, and the index of each factor is established. The result shows that the amount of temperature accumulated over 10* in whole growing season for Lycium barbarum L need is 3450℃·d, as well as the sunlight hours is 1640h. There are lots of factors related to yield in different period of growing season, the most in period of summer fruit growing season. Lycium barbarum L is rare suffer from high temperature in the beginning of summer fruit growing season, and deep influenced by dry - hot wind. This is a new discovery so far research in Lycium barbarum L.
