摘要
以2a生芦笋阿波罗为试材,在地处西辽河平原的内蒙古民族大学试验农场,研究了采笋期间气象条件对绿芦笋产量和质量的影响。结果表明,绿芦笋日合格笋产量、总产量均与近3日(采笋当日及前2日)积温间呈极显著正相关关系,当日温度对笋产量的影响最大,其次为前1日温度和前2日温度。采笋当日与前1日的日平均风速均与不合格笋的支数、产量呈极显著正相关关系,风力作用是形成弯曲笋和散头笋的主要原因之一。日最高、最低气温与不合格笋的支数、产量呈显著或极显著正相关关系,而温度日较差、空气湿度均与不合格笋支数和产量相关不显著。因此,西辽河平原种植芦笋在春季采笋期间设立风障、小拱棚等保护性设施是提高绿芦笋产量和质量的有效途径。
Effects of meteorological factors on yield and quality of green asparagus （Asparagus Officinalis L. ） were studied in 2006 in the West Liaohe Plain, Inner Mongolia. The results showed that the total yield and qualified asparagus spears were extremely significantly positively （P 〈 0.01 ） correlated to the accumulated temperature in the period of the day on spear harvest （DSH） and two days before DSH. The yield and the number of unqualified asparagus spears were significantly positive correlated to the wind velocity during the DSH and one day before DSH （ P 〈 0.01 ）. The wind velocity is one of reasons that loose top spears and twisted spears formed. The yield and the number of unqualified spears were extremely significantly positive correlated to the daily minimum and maximum temperature, but not significant to the relative humidity, daily range of temperature. Building windbreak or small shed mulching with plastic film during the harvest season was an effective way to improve the yield and quality of green asparagus spears in the West Liaohe Plain.
