气象条件对宁夏马铃薯生长及品质的影响
Influence of weather conditions on the potato growth and quality in Ningxia
【摘要】 采用分期播种试验的方法,结合气象站点的气象数据,对宁夏西吉县2008年的马铃薯试验资料进行了统计分析,研究了宁薯4号和陇薯3号的品质与气象因子之间的关系。结果表明:在马铃薯生长期间,宁薯4号和陇薯3号的淀粉、还原糖及Vc含量都因气象因子的改变而受到不同程度的影响。对于宁薯4号,淀粉的积累受气象因子影响程度的强弱为累计降水量>日照时数>积温(≥10℃);Vc含量的积累受气象因子中日照时数的影响较大,且呈正相关;而还原糖含量受气象因子的影响则不明显。
【Abstract】 Effect of planting time and combined with the meteorological data on the potato with Ningshu-4 and Longshu-3 were taken as experimental material and the field experiments of potato in Xiji,Ningxia province were conducted to study the weather conditions on growth and quality of potato.The results showed that in the potato growth period,starch,reducing sugars and vitamin C content have changed due to the meteorological factors by different impacts.For the Ningshu-4,starch accumulation effect by the strength of the climatic factors was in the lever of accumulated precipitation,accumulative total sunshine hours,accumulated temperature;Vitamin C content by the accumulation of climatic factors influencing on the sunshine duration,and positively correlated;And the reducing sugar content in the influence of by meteorological factors were not obvious.
