摘要
运用描述统计和相关性分析等方法,探究19个生物气候因子、海拔、土壤p H和土壤有机质含量等气候环境因素对滇东地区6个马铃薯产量和品质的影响.结果表明:在一定范围内,马铃薯产量与气温的BIO1、BIO5、BIO6、BIO8、BIO9、BIO10和BIO11等7个气候因子和土壤pH呈极显著负相关(p≤0.01),低温和偏酸性土壤有利于马铃薯增产,与BIO12、BIO13、BIO16、BIO18等4个降水因子和土壤有机质含量呈极显著正相关(p≤0.01);还原糖与BIO15呈极显著负相关(p≤0.01),与BIO14和土壤pH呈极显著正相关(p≤0.01);淀粉与BIO14和土壤pH呈显著正相关(p≤0.05);花青素与日较差和BIO12呈极显著正相关(p≤0.01),与海拔呈显著正相关(p≤0.05).
Using descriptive statistics and correlation analysis methods,we studied the impact of 19 bioclimatic factors,altitude,soil pH,and soil organic matter content on the yield and quality of potatoes in the eastern region of Yunnan.The results showed that within a certain range,the yield of potatoes was negatively correlated(p≤0.01)and with high statistical significance to the 7 climate factors of temperature(BIO1,BIO5,BIO6,BIO8,BIO9,BIO10 and BIO11)and soil pH.Low temperature and acidic soil were conducive to potato yield increase.The statistical analysis revealed an extremely significant positive correlation(p≤0.01)between the yield and 4 precipitation factors(BIO12,BIO13,BIO16,BIO18)as well as soil organic matter content.Reducing sugar was inversely and significantly tied(p≤0.01)to BIO15 and significantly positively correlated(p≤0.01)to BIO14 and soil pH.Starch was positively correlated(p≤0.05)with BIO14 and soil pH.Anthocyanins were significantly positively correlated(p≤0.01)with the daily temperature difference and BIO12,and positively correlated(p≤0.05)with altitude.
